MRI of the lower abdomen is more extensive because the soft tissue of the MRI has a higher resolution and the MRI has no radiation, so it can provide a very accurate examination of the lower abdomen. Lower abdominal MRI is different depending on men and women. Women can examine the uterus, ovaries, fallopian tubes, rectum, and bladder, while men can examine the prostate, seminal vesicles, rectum, and bladder. For women, MRI of the uterus can look at fibroids, especially for endometrial cancer. MRI has a clear demarcation of the endometrium of the uterus, so the demarcation of endometrial cancer can be seen better, and adenomyosis can be diagnosed well. If there is a cystic adenoma or cystic adenocarcinoma of the ovary, it can also be well seen and precisely staged. In men with prostate cancer when the PSA is elevated, the MRI can see a reduced signal in the peripheral band, which is highly suspicious of prostate cancer and can be further diagnosed and staged. MRI of the lower abdomen can examine the rectum and can observe the structure of the rectum, and if there is rectal cancer, it can also observe the invasion of rectal cancer to the intestinal wall and surrounding area, and make a good staging of rectal cancer, so MRI of the lower abdomen can provide a lot of useful information.
