There are many benefits to using CT scans as a diagnostic tool. First, and foremost, is their ability to provide high-quality imaging of bones, soft tissue, and blood vessels at the same time. They are particularly helpful when patients are experiencing pain caused by infection and inflammation or from traumatic injury as the speed and accuracy of the imaging can help reduce the risk of serious complications. Since doctors are able to view detailed images quickly, they can also illnesses and prescribe treatment plans immediately that can help you get back to feeling your best as soon as possible.

CT scans also provide real-time imaging which makes them useful for needle biopsies and needle aspirations. This, in turn, can help reduce the likelihood of doctors having to perform more invasive diagnostic testing. They are useful for so many different things that ideally, CT scans can even one day completely eliminate the need for exploratory surgery and surgical biopsies.

While there are many positive aspects of using CT scans for identifying abdominal and pelvic issues, there are also a few limitations. Due to the design of CT machines, patients above 450 pounds may be unable to be scanned as they may not be able to fit into the “tunnel” of the scan machine. CT scans may not be as accurate for patients who have metallic objects within their abdomen, have had a total hip replacement, or currently have stool in their bowels. If you have any of these conditions or if there is a chance that you may be pregnant, it is important to let your doctor and the CT technician know ahead of time.

In addition, CT scans may not be as sensitive in identifying gallstones as having an ultrasound of the abdomen. If a doctor suspects this may be the issue, they may order a different diagnostic test. For some other conditions impacting the liver, kidney, uterus, pancreas, or ovaries, MRIs may be preferable to CT scans.
