Ultrasonography In The Diagnosis And Treatment Of Inflammations Of The Prostate
The prostate gland may be the place of development of acute inflammations and chronic inflammations. Ultrasound images in the course of chronic prostatitis are not characteristic. The echogenicity of the gland parenchyma is not homogenous. The hypoechogenic areas are accompanied by hyperechogenic areas in a disordered manner. The prostate gland may be enlarged and deformed.
Persistent, recurrent symptoms of chronic prostatitis , which are unresponsive to the classical antibiotic therapy, may be an indication for applying targeted antibiotic therapy performed through an intraprostatic injection. The antibiotic is selected in accordance with the result of the microbiological examination of the semen and the assessment of the antibiogram. The most frequently administers antibiotics were: gentamicin, amoxicillin with clavulanic acid, piperacillin. Gentamicin 80 mg is dissolved and administered in the amount of 1 ml to each lobe under USG control with the use of an intrarectal transducer. Piperacillin 2 g is dissolved in 3 ml of the solution and administered in the amount of 1.5 ml to each lobe. While administering the antibiotic it is important to distribute it evenly over the entire lobe and especially on the central zone. After administering the antibiotic to the prostate one should control the uniformity of its distribution within the scope of both lobes using the USG 3D option. The antibiotic solution containing microbubbles of air is visible as a hyperechogenic area .
Transrectal Colour Doppler Imaging
Colour Doppler imaging is well established to illustrate macrovascularity and therefore perfusion. PCa has an increased microvessel density compared with healthy prostatic tissue. Therefore, Doppler visualization of streaming blood within the vasculature may aid in detecting and localizing PCa . In addition, the cancer grade correlates positively with the degree of Doppler signal. Other studies have compared Doppler-guided and systematic biopsies with achieving a detection rate of up to 40%.
Corresponding contrast-enhanced colour Doppler US showing clearly more enhancement of the left side . Targeted biopsy confirmed the presence of a Gleason score 3+4 cancer focus.
As a criterion for capsular penetration an increased capsular flow on colour Doppler imaging has been applied. Another study that performed Doppler TRUS staging revealed a sensitivity of 59% for detecting locally advanced disease. In addition, Doppler imaging also aids in differentiating fibrotic tissue from local recurrence of PCa.
Path To Improved Health
A pelvic ultrasound can be done one of three ways abdominally , vaginally , or rectally . The approach your doctor recommends for your ultrasound depends on the reason for your test and whether you are a man or a woman. A pelvic ultrasound can be used to look at the bladder for both men and women. Your doctor may recommend a pelvic ultrasound of your bladder if you are having difficulty going to the bathroom . It is used on men and women to guide a doctor during a biopsy procedure .
A transabdominal ultrasound is commonly used to monitor the development of a baby in pregnant women at or before 14 weeks in their pregnancy. For this type of ultrasound, the technician will squirt a small amount of warm gel onto your stomach and move the probe or wand back and forth over your stomach. It will check the babys growth, such as height, the length of the babys arms and legs, head size, and more. It will be used to check how far along the mother is in her pregnancy, the babys position in the uterus, the number of babies the mother is carrying, and the amount of amniotic fluid that surrounds the baby. It can be used to look at the babys heart. In some cases, it may be used as a screening method for certain birth defects and developmental abnormalities, such as Down syndrome. A transabdominal ultrasound also can be used to look for tumors in your uterus and other issues related to the female body, whether you are pregnant or not.

Your TNM stage is used to work out if your cancer is localised, locally advanced or advanced. This can help your doctor see how far it has spread and which treatment might be suitable for you.
Cancer that’s contained inside the prostate. Sometimes called early prostate cancer. Possible TNM stages are:
- T stage: T1 or T2
- N stage: N0 or NX
- M stage: M0 or MX.
Cancer that’s started to break out of the prostate, or has spread to the area just outside it. Possible TNM stages are:
- T stage: T1 or T2
- N stage: N1
- T stage: T3 or T4
- N stage: N0 or N1
- M stage: M0.
See A Doctor If You Have Symptoms
Early cancers of the ovaries often cause no symptoms. Symptoms of ovarian cancer can also be caused by other, less serious conditions. By the time ovarian cancer is considered as a possible cause of these symptoms, it usually has already spread. Also, some types of ovarian cancer can rapidly spread to nearby organs. Prompt attention to symptoms may improve the odds of early diagnosis and successful treatment. If you have symptoms similar to those of ovarian cancer almost daily for more than a few weeks, report them right away to your health care professional.

Getting A Prostate Ultrasound For Prostate Cancer
A prostate ultrasound is often used early as a way of diagnosing prostate cancer. Prostate cancer develops in the prostate, a small gland that makes seminal fluid and is one of the most common types of cancer in men.
Prostate cancer usually grows over time, staying within the prostate gland at first, where it may not cause serious harm. While some types of prostate cancer grow slowly and may need minimal or no treatment, other types are aggressive and can spread quickly. The earlier you catch your prostate cancer, the better your chance of successful treatment.
If your doctor suspects you might have prostate cancer they will conduct a number of tests which may include a prostate-specific antigen test, a digital exam of your prostate, and an ultrasound. If your blood work comes back and your PSA is high, your prostate feels abnormal upon exam and the ultrasound show signs of cancer, your doctor will likely want to do a biopsy.
How Do Doctors Screen For Prostate Cancer
Screening for a disease involves testing for it even if no symptoms or history of the illness are present. Because all men are at risk for prostate cancer, especially older men, getting screened is an important health care step for any man to take. For men not experiencing prostate cancer symptoms, the most common screening method is a prostate-specific antigen blood test.
A PSA is a protein created by cells within the prostate gland. A blood test designed to assess PSA levels measures the concentration of PSA within a patients blood. Although there is no definitive cutoff number, the higher the PSA level in a mans blood, the greater the chances he has prostate cancer.
Typically, men without prostate cancer have a PSA level under 4 nanograms of PSA per milliliter of blood , which means those with PSA test results above 4 ng/mL may require further testing. While the likelihood of a patient having prostate cancer decreases dramatically with a 4 ng/mL result, some doctors may request that those with lower PSA levels get additional testing. When done in tandem with other scans and tests, a PSA blood test can help medical professionals provide a more accurate prostate cancer diagnosis.

Who Interprets The Results And How Do I Get Them
A radiologist, a doctor trained to supervise and interpret radiology exams, will analyze the images. The radiologist will send a signed report to the doctor who requested the exam. Your doctor will then share the results with you. In some cases, the radiologist may discuss results with you after the exam.
Follow-up exams may be needed. If so, your doctor will explain why. Sometimes a follow-up exam is done because a potential abnormality needs further evaluation with additional views or a special imaging technique. A follow-up exam may also be done to see if there has been any change in an abnormality over time. Follow-up exams are sometimes the best way to see if treatment is working or if an abnormality is stable or has changed.
What Is Ultrasound Imaging
An ultrasound exam is a painless diagnostic technique that makes use of how sound waves travel through the body. When sound waves pass through the body, they bounce off tissues and organs in certain ways. The reflected waves can be used to make images of the organs inside. The sound waves dont hurt the body, and theres no radiation.
Ultrasound imaging may be done in the health providers office, in the hospital, or in an outpatient facility. The reason for the study and details of the case will help decide where the test should be done.
In most cases, very little needs to be done before an ultrasound exam. The patient lies on the exam table. A clear, water-based gel is put on the skin over the part to be checked. This gel helps the sound waves go through the body. A hand-held probe is then moved over that part. For prostate ultrasound exams, a specially designed probe is inserted into the rectum.
There is no risk of radiation. The patient can return to daily tasks right away after the test.
Some exams, such as a bladder scan for residual urine, dont call for the user to have a lot of experience. Other exams, such as ultrasound of the kidneys, testicles or prostate, call for the user to have more experience or skill.

Preparing For Your Pet
For most PET-CT scans, you need to stop eating about 4 to 6 hours beforehand. You can usually drink water during this time. You might have instructions not to do any strenuous exercise for 24 hours before the scan.
Some people feel claustrophobic when theyre having a scan. Contact the department staff before your test if youre likely to feel like this. They can take extra care to make sure youre comfortable and that you understand whats going on.
Your doctor can arrange to give you medicine to help you relax, if needed.
Biopsy During Surgery To Treat Prostate Cancer
If there is more than a very small chance that the cancer might have spread , the surgeon may remove lymph nodes in the pelvis during the same operation as the removal of the prostate, which is known as a radical prostatectomy .
The lymph nodes and the prostate are then sent to the lab to be looked at. The lab results are usually available several days after surgery.

Getting A Prostate Ultrasound
Ultrasound imaging uses high-frequency sound waves to create a picture of the prostate. Ultrasounds are used early in the diagnostic process to determine whether your prostate is enlarged or has an abnormal or asymmetrical shape. If your prostate is enlarged without any other characteristics of cancer, you may just have benign prostate hyperplasia. As you age, your prostate increases in size. An ultrasound can help your doctor determine if your prostate size increase is normal and age-related or a sign of prostate cancer.
Ultrasound is also used very frequently during a prostate biopsy to guide the physician to biopsy exactly where needed. In order to produce an image of the prostate, a thin ultrasound probe is inserted a short distance into the rectum. This probe emits high-frequency sound waves and detects their return. These sound waves can then be detected and measured as they reflect off of various structures inside the body.
When sound waves echo off of an object, they change slightly. The ultrasound machine can interpret these very tiny changes in the character of the returning sound wave to make determinations about the object that it has hit. Different types of structures reflect or echo sound waves differently. These differences can be detected and an image produced that shows where one structure stops and another starts. This allows for a detailed view of the area near the ultrasound probe.
Changing Standard Of Care
Will a Prostate MRI eventually become the standard of care? Dr. Walker thinks so. Across the country and in the minds of urologists, he says the Prostate MRI is becoming essential for the management of patients at risk of prostate cancer.
Now I think a lot of docs are becoming more comfortable using the MRI ahead of time to get a little bit more accurate biopsy. And more patients actually know about the MRI technology and even ask about it. -Dr. Todd Brandt of Metro Urology

Can Ultrasound Detect Cancer
An ultrasound uses sound waves to create pictures of organs and tissues inside the body and has been used for many different conditions, including abdominal disorders, suspicious lumps, and other disease in the body.
The technician places a sound wand onto the area in question. The sound waves send a picture to a monitor and several snapshots are taken. A radiologist then reads the images and can get a good first impression of abnormalities. This article explains the role of ultrasound in detection of cancer and how the test works.
How Do I Prepare For My Exam
- Please arrive 15 minutes prior to your appointment.
- Take all prescribed medications as directed.
- Wear comfortable clothes.
- 90 minutes prior to your appointment, empty your bladder. Then drink one litre of water within the next 30 minutes.
- If you have a problem keeping a full bladder, you may arrive early to drink your water at the clinic. If you are too uncomfortable, you may void some urine to relieve the pressure but try not to empty the bladder.

What Is A Trus
Ultrasound scans use high frequency sound waves to create a picture of a part of the body. A prostate ultrasound scan can show up changes in your prostate, including abnormal growths.
The ultrasound scanner has a microphone that gives off sound waves. The sound waves bounce off the organs inside your body, and the microphone picks them up. The microphone links to a computer. This turns the sound waves into a picture on the screen.
You might have a sample of tissue taken from the prostate gland at the same time. This is called transrectal ultrasound guided biopsy.
Can A Prostate Ultrasound Show Cancer
ultrasoundprostateprostate cancer
In detecting prostate cancer, your doctor may also recommend a transrectal ultrasound. During this exam, a small probe is inserted into the rectum so sound waves may provide a picture of the prostate and measure its size. Images will reveal tumors, calcifications and enlargement of the prostate.
Secondly, what is the most accurate test for prostate cancer? The prostate health index is one such test that is a more accurate blood test and measures your risk for having prostate cancer. It’s approved by the FDA for men who have PSA scores between 4 and 10.
Also Know, how accurate is a prostate ultrasound?
A prostate ultrasound is more accurate than an X-ray. This is because your technician can see the images as the transducer moves through your rectum rather than having to take a snapshot and develop the images. Ultrasound tests are also safer than X-rays because they don’t produce any dangerous radiation.
Can an ultrasound detect cancer?
Ultrasound is very good at getting pictures of some soft tissue diseases that don’t show up well on x-rays. Ultrasound cannot tell whether a tumor is cancer. Its use is also limited in some parts of the body because the sound waves can‘t go through air or through bone.

What Is Examined During A Renal/pelvic Ultrasound
During a renal/pelvic ultrasound, the kidneys are examined to determine their size, shape and exact position. The bladder may be evaluated to help determine the cause of unexplained blood in the urine or difficulty in urinating, or to look for bladder stones.
Before the renal or pelvic ultrasound
You do not have to fast for this test, but your bladder must be full. See instructions below.
- Finish drinking one quart of fluids 1 hour before your scheduled test. Once you start drinking, do not empty your bladder until the exam is completed.
- Failure to follow the above preparation will result in delays or possible cancellation of your examination.
On the day of the test
Please do not bring valuables such as jewelry and credit cards.
- It is very important to arrive for the test with a full bladder. This allows the technologists and radiologist to view the bladder while it is full and after it has been emptied.
- Your ultrasound test is performed by registered, specially trained technologists, and interpreted by a board-certified radiologist.
- You may be asked to change into a hospital gown.
During the test
- You will lie on a padded examining table.
- A warm, water-soluble gel is applied to the skin over the area to be examined. The gel does not harm your skin or stain your clothes.
- A probe is gently applied against the skin. You may be asked to hold your breath briefly several times.
The ultrasound takes about 40 minutes to complete.
After the test
