Diffusion-weighted imaging (DWI) is a technique that assesses the cellularity, tortuosity of the extracellular/extravascular space, and cell membrane density based on differences in water proton mobility in tissues. The strength…
Magnetic resonance (MR) imaging is a robust, noninvasive tool with the ability to perform a wide array of diagnostic functions within the abdomen. Over the last decade, there has been…
Assessment of tumor response is crucial in determining the effectiveness of loco-regional and systemic therapy, and for determining the need for subsequent treatment. The ultimate goal is to improve patient’s…
The Liver Imaging–Reporting and Data System (LI-RADS) is a comprehensive system for standardized interpretation and reporting of computed tomography and magnetic resonance examinations performed in patients at risk for hepatocellular…
Hepatocellular carcinoma (HCC) is the fastest growing cause of cancer-related death in the United States. Cirrhosis is the most important risk factor for HCC. Dynamic contrast-enhanced magnetic resonance (MR) imaging…
Magnetic resonance (MR) can characterize specific tissue subtypes, thus facilitating focal liver lesion diagnosis. Focal liver lesions that are isointense to hyperintense to liver on T1-weighted images are usually hepatocellular…
Intravenous contrast agents are important in the performance of liver magnetic resonance (MR) imaging. These agents differ in their physical properties. These differences can be exploited to optimize imaging protocols…
This article describes a basic 1.5-T hepatic magnetic resonance (MR) imaging protocol, strategies for optimizing pulse sequences while managing artifacts, the proper timing of postgadolinium 3-dimensional gradient echo sequences, and…
Peter S. Liu, MD, Editor Richard G. Abramson, MD, Editor Although evaluation of the hepatobiliary system is considered one of the more common indications in body MR imaging, it remains…
Suresh K. Mukherji, MD, MBA, FACR, Consulting Editor I have always viewed hepatobiliary magnetic resonance (MR) as a microcosm of how to expand technology and grow our specialty. I was…
