Can MRI detect prostate cancer?

Prostate cancer is a malignant disease with a high incidence and mortality rate among modern men. In life, people are afraid of cancer. When the prostate has some uncomfortable symptoms, it does not mean that you have prostate cancer. This disease requires a series of tests to be confirmed. So can MRI detect prostate cancer? The following is an introduction to the examination methods of prostate cancer.

1. Ultrasound examination can detect low-echo nodules in the prostate, but they must be differentiated from inflammation or stones.
2. Radionuclide bone scanning can often show metastatic lesions earlier than X-rays.
3. CT or MRI examinations can show prostate morphological changes, tumors and metastasis. The main CT manifestations of prostate cancer are that the cancer foci appear as low-density areas with little enhancement during enhanced scanning, the capsule appears irregular, the fat around the gland disappears, and the seminal vesicles may be blurred when the seminal vesicles are invaded, the bladder and seminal vesicle angle disappears or the seminal vesicles are enlarged; when the tumor invades the bladder or the organs around the prostate, the pelvic CT may show corresponding changes. When the pelvic lymph nodes have tumor metastasis, CT can judge whether metastasis has occurred based on the changes in the size of the pelvic lymph node group.
The MRI examination of prostate cancer mainly uses the T2-weighted sequence. On the T2-weighted image, if a low-signal defect area appears within the high-signal peripheral zone of the prostate, if the prostate band structure is destroyed, and the boundary between the peripheral zone and the central zone disappears, prostate cancer should be considered.
4. Prostate biopsy can be used as a method to confirm prostate cancer. Failure to remove tumor tissue does not negate the diagnosis.
