Inflammatory Demyelinating Diseases
Abstract The spinal cord is commonly affected in inflammatory demyelinating diseases (IDD) of the central nervous system. In the most common IDD, multiple sclerosis (MS), the importance of spinal cord…
MAGNETIC RESONANCE IMAGING
Rationale for Quantitative MRI of the Human Spinal Cord and Clinical Applications
Abstract In vivo spinal cord imaging is now commonly used to diagnose patients with neurodegenerative disorders. Quantitative MRI (qMRI) techniques applied to the spinal cord show promise for predicting prognosis…
Sectional Anatomy of the Postnatal Brain
This section discusses the normal magnetic resonance (MR) imaging appearance of the brains of children after term delivery up to the age of 18 months. We illustrate this topic with…
Sectional Anatomy of the Fetal Brain
The major part of this section is a pictorial review of cross-sectional fetal brain anatomy using magnetic resonance (MR) imaging matched as closely as possible with postmortem histologic sections. It…
Surface Anatomy of the Brain
The adult human brain has a highly complex external morphology, and this is particularly true of the cerebral hemispheres. The clinical neuroimager needs to know the normal patterns of cortical…
Wall Motion Stress Magnetic Resonance
• CMR can detect myocardial ischemia using exercise and pharmacologic stressors with accuracy comparable to nuclear and echocardiography. • Accuracy of CMR wall motion stress testing for ischemia may be…
Carotid Atherosclerotic Disease
• Multiple contrast weighted imaging sequences (including bright- and black-blood techniques) are needed for accurate assessment of the luminal surface condition and plaque composition. • MRI is able to visualize…
Plaque and Wall Assessment
• Vascular magnetic resonance imaging is noninvasive, does not involve ionizing radiation, and can provide extensive coverage of large arteries with high accuracy and reproducibility. • As such, it can…
Coronary Anomalies
• Define the most common and clinically significant coronary anomalies. • Define common types of coronary fistulae. • Define which coronary anomalies are low versus high risk. • Outline the…
Coronary Arteries and Bypass Grafts
• Free-breathing 3D coronary MR angiography allows for visualization of all major coronary arteries without administration of contrast medium or radiation exposure to the patient. • Acquisition of free-breathing whole…
