1) Review the current evidence on HCC screening and surveillance. 2) Introduce the concept of abbreviated MRI using gadoxetic acid for HCC screening. 3) Review early results of AMRI for HCC screening.

HCC is the fastest growing cause of cancer death in the United States. Practice guidelines recommend semi-annual HCC surveillance using ultrasound for high-risk patients to permit detection of HCC at an early stage, enabling effective treatment, and potentially improving survival. Due to known limitations of ultrasound, there is recent interest in developing fast MRI methods for HCC screening. In this presentation, we will discuss a novel abbreviated MRI (AMRI) exam designed to detect early-stage HCC in cirrhotic patients. AMRI is performed after gadoxetate disodium injection without the use of dynamic acquisitions, and combines only 3 sequences: T1 during the hepatobiliary phase, diffusion-weighted imaging and T2 SS FSE. The total exam time is <=15 min, thus potentially decreasing costs. We will discuss pros and cons of AMRI, future directions and other alternatives.

1) To recognize the role of MRI in the follow up of incidental cystic pancreatic lesions. 2) To understand the potential advantages and disadvantages of a short MRCP protocol for the follow up of incidental cystic pancreatic lesions.

The diagnosis of incidental cystic pancreatic lesions has increased dramatically in the last decades due to widespread use of cross-sectional imaging and improvements in image quality. While the vast majority of these lesions exhibit a benign behavior a minority of them can evolve into invasive malignancies. This has led to the development and implementation of practice guidelines for the follow up of these lesions by several major medical organizations, all of which recognize serial imaging as the pillar of such strategies. Magnetic resonance cholangiopancreatography (MRCP) offers several advantages for the follow up of incidental pancreatic cystic lesions including excellent soft-tissue contrast and sensitivity to detect fluid and delineate ductal structures of the pancreaticobiliary system, and the lack ionizing radiation. However, several qualities may challenge its broad implementation including long acquisition times, cost, and concerns about the repeated administration of gadolinium-based contrast agents during serial examinations. In this talk we will review the potential advantages and disadvantages of a short MRCP protocol for the follow up of incidental cystic pancreatic lesions.
