Whats better for diagnosing pancreatic cancer? Ct scan or mri? 34yr male. I've had normal ultrasound and CT scan with contrast. Still worried.
CT, ERCP, MRCP: Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures... Blood tests including tumor markers: ca-19-9, ca-15-3, and cea can alert the clinician for ca. Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy. Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority. ...Read more

If so and negative, your comprehensive and perhaps more than appropriate workup shows within the limits of present technology, you don't have a detectable cancer. Longstanding gerd can be a pre-cancerous change over the years however and may warrant future follow-up endoscopy. ...Read more
