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…
Magnetic resonance (MR) imaging is an established modality for the evaluation of musculoskeletal structures, including the knee. Metallic implants are increasingly used and techniques to minimize artifacts are continuously improving….
In pediatric patients, the high resolution and excellent soft-tissue contrast of magnetic resonance (MR) imaging allows for complete evaluation of osseous and soft-tissue structures around the knee joint, and its…
The knee has unique anatomy regarding the relationship between the synovial and capsular layers, with interposed fat pads at certain locations. The extrasynovial impingement and inflammation syndromes about the knee…
Osteoarthritis is characterized by a decrease in the proteoglycan content and disruption of the highly organized collagen fiber network of articular cartilage. Various quantitative magnetic resonance imaging techniques have been…
The magnetic resonance (MR) imaging presentations of arthritis of the knee are important for radiologists to recognize because these disorders are often clinically unsuspected. When they are known or clinically…
