The role of magnetic resonance imaging for prostate cancer
What is the role of MRI for prostate cancer? Prostate cancer is a type of tumor disease that requires MRI as adjuvant treatment. Today, what I want to popularize for you is what are the functions of magnetic resonance examination for prostate cancer, and interested friends should not miss it.
Symptoms of prostate cancer
Compression symptoms: Compression of the urethra by the enlarged prostate gland can cause progressive dysuria, which is manifested by thin urine line, short range, slow urine flow, interrupted urine flow, post-urine dribbling, incomplete urination, labored urination, and frequent urination, urgency, increased nocturia, and even urinary incontinence.
Tumors that compress the rectum can cause constipation or intestinal obstruction, compress the vas deferens and cause lack of ejaculation, compress nerves causing perineal pain, and radiate to the sciatic nerve.
Metastatic symptoms: prostate cancer can invade the bladder, seminal vesicles, vascular nerve bundles, causing hematuria, hematospermia,impotencePelvic lymph node metastases can cause edema in both lower extremities. Prostate cancer is often prone to bone metastasis, causing bone pain, pathological fractures, and paraplegia. Prostate cancer can also invade the bone marrow, causing anemia or decreased blood count.
Next, let's take a look at what MRI can do for prostate cancer.
The role of magnetic resonance imaging for prostate cancer
The outer edge of the prostate on the side of the lesion is irregularly bulging, and the edges are not smooth.
Posterolateral protrusion or angulation of the tumour with asymmetry of the bilateral neurovascular plexus.
Shows signs of direct penetration of the tumour through the capsule and entry into the surrounding hyperintense fat, and loss of fat in the neurovascular plexus or prostate-rectal fossa.
Tumors that show hypointensity enter and surround the seminal vesicles from the base of the prostate, resulting in the presence of hypointense foci in the seminal vesicles with normal T2 hyperintensity and the loss of the seminal vesicle angle of the prostate.
It shows that the tumor invades the seminal vesicle glands along the ejaculatory duct and the seminal vesicle wall disappears.
Focal areas of hypointensity within the seminal vesicles.
Therefore, it is necessary to have an MRI examination for prostate cancer.
