Which is better MRI or CT scan for abdomen?

MRI is more accurate than a CT scan or other tests for certain conditions but less accurate for others. The function of the small and large bowel (intestines) is not readily visible. Disadvantages include the high cost, long duration of the scan, and sensitivity to movement.

Increased wall thickness of the stomach in the CT scan is considered pathological in the early diagnosis of gastric cancer. The need for early diagnosis of gastric cancer via CT scan has been the subject of many studies by investigating nonpathological gastric wall thickness.

What can a CT scan of the abdomen show?

What can a CT scan tell you about esophageal cancer?

A CT scan uses x-rays to produce detailed cross-sectional images of your body. This test can help tell if esophageal cancer has spread to nearby organs and lymph nodes (bean-sized collections of immune cells to which cancers often spread first) or to distant parts of the body.
