The role of MRI in prostate cancer screening

What is the role of MRI in prostate cancer? Prostate cancer is a type of tumor disease that requires MRI to assist in treatment. Today, we will share with you the role of MRI in prostate cancer. Interested friends should not miss it.

Symptoms of prostate cancer

Compression symptoms: The gradually enlarged prostate gland compresses the urethra and can cause progressive dysuria, which is manifested as thin urine stream, short range, slow urine flow, interrupted urine flow, dripping after urination, incomplete urination, labored urination, frequent urination, urgency, increased nocturia, and even urinary incontinence. Tumor compression of the rectum can cause dysuria or intestinal obstruction, and can also compress the vas deferens to cause lack of ejaculation, and compress the nerves to cause perineal pain, which can radiate to the sciatic nerve.

Metastatic symptoms: Prostate cancer can invade the bladder, seminal vesicle, and blood vessels and nerve bundles, causing hematuria, hematospermia, and impotence. Pelvic lymph node metastasis can cause edema of both lower limbs. Prostate cancer is often prone to bone metastasis, causing bone pain or pathological fractures, paraplegia. Prostate cancer can also invade the bone marrow, causing anemia or a decrease in the whole blood count.

Next, let’s take a look at the role of MRI in prostate cancer screening.

The role of magnetic resonance imaging in prostate cancer screening

The outer edge of the prostate on the affected side bulges irregularly and the margins are not smooth.

The tumor protrudes posterolaterally or shows angulation signs, and the bilateral neurovascular plexuses are asymmetric.

It shows signs such as the tumor directly penetrating the capsule and entering the surrounding high-signal fat, and the disappearance of fat in the neurovascular plexus or the prostate rectal fossa.

The low-signal tumor enters and surrounds the seminal vesicle from the base of the prostate, resulting in the appearance of low-signal foci within the normal T2 high-signal seminal vesicle and the disappearance of the prostate-seminal vesicle angle.

It showed that the tumor invaded the seminal vesicle along the ejaculatory duct and the seminal vesicle wall disappeared.

Focal low signal area in the seminal vesicle.

From this point of view, it is necessary to do MRI examination for prostate cancer.
