Almost: Usually a ct will allow the radiologist to see dilation of the ducts in the liver and pancreas even before there is a discrete mass to find. If medical suspicion is high enough, occasionally an MRI and/or mrcp will be ordered as follow up, particularly if there are also laboratory abnormalities. Talk to your doctor about this, or seek a surgical or gastrointestinal specialist consult.

No test: No test can always detect the disease it was designed to find, and the ct scan is no exception. For pancreatic and bile duct cancer, ct scan is a very good test, but often uses along with ultrasound, endoscopic ultrasound, MRI and endoscopy (ercp). Even with all these tests, surgical exploration may still be indicated in certain circumstances. Your gallbladder may be the problem, not cancer.

No test is perfect!: No test is 100 percent accurate. Although a multiphase ct with contrast is a very good test for pancreatic or bile duct cancer, it is not a perfect test. Mri, mrcp and ERCP are all tests that may be useful. Generally, imaging for this problem begins with a ct, with the additional tests based on the ct results, as well as lab tests and other examinations.
