Advances in CT Imaging of GI Malignancies.

There have been multiple advances in multidetector CT over the past decades which have directly improved the quality of oncologic imaging. Not only has the most recent generation of CT scanners allowed markedly improved spatial and temporal resolutions, but modern imaging protocols have been refined and are now specifically tailored to the patient's known malignancy. Moreover, the last few years have also seen the widespread use of 3-D imaging (including volume rendering and maximum intensity projection imaging), which has also markedly improved the quality of CT diagnosis. This article discusses the state-of-the-art advances in the imaging of pancreatic, hepatic, and small bowel malignancies, each of which illustrates the strengths of modern MDCT in oncologic diagnosis and staging.
