Prostate MRI basal shifted band dwi high signal and adc slightly low signal, consider prostate cancer is not excluded, please combine with clinical, puncture biopsy if necessary. DWI is a special sequence in MRI, full name is diffusion weighted imaging, DWI is often used in the diagnosis of tumor disease, if the DWI signal of prostate MRI basal migratory zone is high, it suggests that there may be malignant tumors, or other prostate diseases such as prostatitis, prostate soft tissue injuries and so on. ADC refers to the apparent diffusion coefficient of magnetic resonance, which mainly evaluates the diffusion movement of water molecules in the living body, and a low ADC signal usually means that the cancer cells will produce a restricted diffusion of water molecules, which can be used to detect whether the patient has prostate cancer or not.A low ADC value suggests that no matter whether the lesion is located in the peripheral band of the prostate or in the migratory zone, it suggests that there is a possibility of prostate cancer. In conclusion, the high signal of dwi and low signal of adc in the basal migratory zone of prostate MRI is not an exclusion of prostate cancer, and it is recommended that the patient obtains a tissue test if necessary to determine the presence of prostate cancer.
