Specific requirements for MRI diagnosis of prostate cancer

I believe that everyone has heard of MRI in life and in TV dramas. However, people have not yet formed a clear understanding of the use of MRI. Some people may have such questions, can MRI confirm prostate cancer? If MRI can confirm prostate cancer, what are the specific requirements? Below, the editor will give you some knowledge in this regard.

We need to understand what prostate cancer is. Prostate cancer is a malignant tumor that occurs in the prostate tissue. It has a very high incidence and mainly occurs in men. It is the result of abnormal growth of prostate acinar cells. Among them, prostate cancer mainly includes two major symptoms.

First, compression symptoms. Prostate enlargement compresses the urethra, which can cause dysuria, characterized by short urination, frequent urination, urgency, and even incontinence. Compression by prostate cancer can lead to difficulty in defecation. The prostate can also compress the vas deferens, leading to insufficient ejaculation. Compression of nerves can cause pain in the reproductive organs.

Second, metastatic symptoms. Prostate cancer can invade the bladder, seminal vesicle, and vascular nerve bundles, causing symptoms such as hematuria, hematuria, and impotence. Pelvic lymph node metastasis can cause lower limb edema. Prostate cancer is often prone to bone metastasis, causing bone pain or pathological fractures and paraplegia. Prostate cancer can also invade the bone marrow, leading to anemia or a decrease in total blood count.

Current medical research shows that MRI is an effective way to diagnose prostate cancer. It is understood that MRI is a nuclear physics phenomenon that mainly uses image reconstruction technology to reconstruct the signals generated by nuclei in a strong magnetic field. The specific requirements for diagnosing prostate cancer with MRI are as follows:

First, correct patient preparation and posture. The patient should have a moderately filled bladder. Of note, an overfilled bladder can cause wave artifacts. An empty bladder is not conducive to observing the relationship between the prostate and the bladder wall. When the patient is supine, the centerline should be above the pubic bone.

The above is the knowledge about MRI diagnosis of prostate cancer that the editor has shared with you. I hope that you can have a clearer understanding of the purpose of MRI and the causes and clinical symptoms of prostate cancer. Moreover, when using MRI to diagnose prostate cancer, you must cooperate under the guidance of a doctor.
