Prostate MRI generally cannot confirm the diagnosis of prostate cancer, and can only be used as an auxiliary examination to diagnose the disease, and prostate pathological tissue examination is the gold standard for the diagnosis of prostate cancer.
When prostate cancer patients undergo MRI, there will be low signal defects in the peripheral band of the prostate with high signal on the T2-weighted image, while the signal of the tumor is more uniform on the T1-weighted image. In addition, patients undergoing prostate MRI can also clarify the relationship between the prostate envelope and pelvic lymph nodes, surrounding tissues, and bone metastases.
This is more helpful for assisting in the diagnosis of prostate cancer. The examination is more meaningful for diagnosing early prostate cancer, but cannot be used as the standard for confirming the diagnosis of prostate cancer. At present, pathological tissue examination after prostate puncture biopsy is the gold standard for diagnosing prostate cancer.
Prostate MRI is usually not the standard for diagnosing prostate cancer. If patients want to confirm the diagnosis of prostate cancer, they need to consult a doctor in time, and the doctor will decide whether to perform prostate puncture biopsy according to the patient’s clinical manifestations and the results of various tests to diagnose whether there is prostate cancer or not.
