MR Imaging of Ductal Carcinoma In Situ
Ductal carcinoma in situ (DCIS) now accounts for well over 20% of cancers diagnosed in mammography screening programs. This article reviews the biology of DCIS and the unique kinetic and…
Implementing a Breast MR Imaging Program: All Things Considered
The role of magnetic resonance (MR) imaging in breast imaging and evaluation has increased rapidly. MR imaging now encompasses diagnostic evaluation as well as screening for breast cancer in high-risk…
Breast Magnetic Resonance Imaging: Current Clinical Indications
Breast magnetic resonance (MR) is highly sensitive in the detection of invasive breast malignancies. As technology improves, as interpretations and reporting by radiologists become standardized through the development of guidelines…
The BI-RADS Breast Magnetic Resonance Imaging Lexicon
The Breast Magnetic Resonance Imaging Lexicon was designed to standardize interpretation and reporting of breast magnetic resonance (MR) imaging findings, ultimately improving communication between radiologists and clinicians and facilitating patient…
Tumors of the Liver and Intrahepatic Bile Ducts: Radiologic–Pathologic Correlation
Primary tumors of the liver can be classified pathologically based on their cell of origin into epithelial tumors, arising from hepatocytes or biliary epithelium, and nonepithelial tumors, including mesenchymal tumors…
Functional Magnetic Resonance Imaging of the Liver: Parametric Assessments Beyond Morphology
There is growing interest in exploring and using functional imaging techniques to provide additional information on structural alterations in the liver, which often occur late in the disease process. This…
Magnetic Resonance Imaging of the Liver: Sequence Optimization and Artifacts
The liver is one of the most challenging organs of the body to image with magnetic resonance because it is large and mobile, receives a dual blood supply, and is…
Imaging at Higher Magnetic Fields: 3 T Versus 1.5 T
Clinical hepatobiliary magnetic resonance (MR) imaging continues to evolve at a fast rate. However, three basic requirements must still be satisfied if novel high-field MR imaging techniques are to be…
MR Imaging Evaluation of the Hepatic Vasculature
Assessment of the hepatic vasculature is essential for tumor staging, surgical planning, and understanding of liver disease. Technological advances have made contrast-enhanced magnetic resonance (MR) imaging comparable to multidetector-row computed…
Magnetic Resonance Cholangiopancreatography of Benign Disorders of the Biliary System
Magnetic resonance cholangiopancreatography (MRCP) is an elegant MR technique for noninvasively delineating the biliary system. Technologic advances in MRCP acquisition and processing and the routine availability of three-dimensional sequences have…
