Contrast Media in Breast Imaging
Although mammography is the standard imaging modality for detection of breast cancer, magnetic resonance (MR) imaging is a valuable adjunct and, in certain cases, is the imaging of choice. Contrast-enhanced…
Peripheral MR Angiography
Since the introduction of contrast-enhanced MR angiography (MRA), several different techniques for imaging the peripheral arteries have evolved. All of them provide good diagnostic image quality, whereas some older techniques…
Use of Magnetic Resonance Imaging Contrast Agents in the Liver and Biliary Tract
This article presents an overview of liver and biliary contrast agents including their mechanisms of action, dosage and elimination, current clinical indications, and potential future uses. • Hepatobiliary-specific contrast agents…
Advanced Techniques Using Contrast Media in Neuroimaging
This article presents an overview of advanced magnetic resonance (MR) imaging techniques using contrast media in neuroimaging, focusing on T2*-weighted dynamic susceptibility contrast MR imaging and T1-weighted dynamic contrast-enhanced MR…
Contrast-Enhanced Magnetic Resonance Angiography
Magnetic resonance (MR) angiography is a powerful tool for the evaluation of cervical and intracranial vasculature. Both noncontrast and contrast-enhanced MR angiography can provide exquisite vascular contrast and detail without…
Contrast-Enhanced MR Imaging in Neuroimaging
MR imaging without and with gadolinium-based contrast agents (GBCAs) is an important imaging tool for defining normal anatomy and characteristics of lesions. GBCAs have been used in contrast-enhanced MR imaging…
Use of Contrast Media in Neuroimaging
Since their introduction, gadolinium-based contrast media are routinely used in most CNS MR imaging indications. Due to their paramagnetic effect, they significantly shorten the T1 relaxation times of the tissue…
Gadolinium-Based Magnetic Resonance Contrast Agents for Neuroradiology
There has been much progress in contrast enhanced neuroradiologic magnetic resonance imaging in the almost 25 years since the first gadolinium-based contrast agent was approved in the United States. Much…
MR Imaging and Ultrasound Correlation of Hip Pathologic Conditions
Magnetic resonance (MR) imaging has become the workhorse in the imaging evaluation of the painful or clinically abnormal hip. It provides an excellent anatomic overview and demonstration of the bony…
MR Imaging of the Hip
MR imaging of the hip is frequently used in symptomatic patients before hip preservation surgery; it is used as a decision-making tool and as a planning tool. The MRI can…
