MR Assessment of Oral Cavity Carcinomas
Approximately half of head and neck carcinomas arise from the oral cavity. Imaging plays an essential role in the preoperative evaluation of oral cavity carcinomas. MR imaging is particularly advantageous…
Aggressive Inflammatory and Neoplastic Processes of the Paranasal Sinuses
Although uncommon, sinonasal malignancies and aggressive inflammatory processes are entities every radiologist will encounter during the evaluation of routine sinus imaging studies. A high index of suspicion is necessary for…
MR Imaging of the Temporomandibular Joint
MR imaging allows detailed evaluation of temporomandibular (TMJ) anatomy because of its inherent tissue contrast and high resolution. Joint biomechanics can be assessed through imaging patients in the closed and…
MR Imaging of the Brachial Plexus
MR imaging of the brachial plexus assesses the continuity of the elements, relationship, and orientation of lesions, evaluates morphology, and reveals secondary features of plexopathies. The selection of sequences and…
Contrast-Enhanced Cardiac Magnetic Resonance Imaging
Cardiac magnetic resonance (CMR) imaging has significantly evolved in the past decade and is well established in the evaluation of coronary artery disease (CAD). The evaluation of cardiac anatomy and…
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…
