A ct of a man’s lower abdomen from front to back basically examines his prostate, ureters, bladder, and some of his bowel tissue. 1. Examination of the ureter and bladder can look for the presence of stones or other lesions within these tissues, and examination of the prostate can determine whether there are abnormalities in its function and organization, such as the presence of prostatic hypertrophy and other diseases. 2. Examination of the intestinal area can be roughly divided into two sections, the appendix, descending colon, cecum and sigmoid colon and rectum, the first half to see whether there is obvious occupation obstruction and other problems, the appendix area can focus on whether there is the presence of fecaliths, the second half can look at the internal accumulation of fecal matter, and can even check whether there is a malignant tumor. The internal organs of the lower abdomen can be initially examined by CT, and it is recommended to consult a doctor promptly if there is any discomfort.
