Some CT scans require the use of a special dye known as contrast material in order to better emphasize the parts of your body that are being inspected. Because the contrast material is opaque to X-rays and looks white in pictures, it is useful for highlighting structures such as blood arteries, intestines, and other anatomical components.

What can a CT scan with contrast miss?
Misreadings and incorrect interpretations of CT images are possible. Imaging tests are typically unable to determine whether or not a change was caused by cancer. CT scans have the potential to give both false negative and false positive results. It is possible for a CT scan to miss cancer, as well as tumors located in other parts of the body.
What cancers can a CT scan detect?
A CT scan can easily detect the following cancers: A cancer diagnosis can be made with the use of a CT scan. At American Health Imaging (AHI), we provide diagnostic CT scans that are able to identify cancers of the bladder, kidneys, ovary, stomach, and even the colon with relative ease.
What are black spots on abdominal CT scan?
Overview. This CT scan of the abdomen reveals cysts in both the liver and the kidneys (polycystic disease). The huge organ that can be seen on the left side of the image is the liver. Cysts are the black patches that can be seen in the liver.
Can you see inflammation on a CT scan?

Can a CT scan show bowel inflammation?
A CT scan will reveal inflammatory diverticula, inflammation of the intestinal wall, pericolic fat stranding, and the problems that are associated with these conditions. CT has the ability to visualize both pericolonic and colonic problems, which leads to a more accurate diagnosis for the patient and a higher quality of treatment overall.
What organs are seen on a CT scan of abdomen and pelvis with contrast?
- Your abdomen and pelvis will be scanned using computed tomography (also known as CAT or CT), as per your doctor’s request.

What’s the difference between a CT scan and a CAT scan?

How small of a tumor can a CT scan detect?
However, because of the physical constraints, the smallest size of a lesion that may be measured with CT is around 3 millimeters (24). Contemporary MR imaging methods have detection limitations of lesions that are comparable (25).
Why would a doctor order a CT scan?
- In the case of bones and joints, CT scans are able to detect issues such as complicated bone fractures and malignancies.
- CT scans may detect conditions like cancer, heart disease, emphysema, or liver tumors, as well as assist doctors notice any changes that may have occurred in those conditions.
