Pelvic CT is used to look for abdominal hematomas, pelvic fractures, and part of the hip joint. 1. Pelvic CT is mainly used for trauma or other conditions that cause pain around the pelvis. The first thing that needs to be ruled out is whether there is bleeding or hematoma around the pelvis or in the lower abdomen, because the most dangerous part of pelvic fracture is the large amount of blood loss leading to hemorrhagic shock. 2. The continuity of the pelvic bone can then be observed, and if there is a break in continuity it is a sign of a fracture. Pelvic fractures can also be seen in a portion of the femoral head, such as femoral neck fractures and ischemic necrosis of the femoral head. It is important to note that CT is a very specialized test. It is difficult for people without formal medical studies to read and understand it, so it is still necessary for the doctor to make a comprehensive judgment in combination with the condition and signs.
