Blood Flow Velocity Assessment
The idea of mapping measurements of blood flow onto a magnetic resonance (MR) image was first discussed in an article by Singer in 1978. The methods that followed could generally…
CARDIOVASCULAR IMAGING
Myocardial Perfusion Imaging Theory
Introduction The concept of injecting a tracer into the blood stream and detecting its transit and distribution in the heart muscle for the assessment of myocardial perfusion is well established…
Cardiovascular Magnetic Resonance Contrast Agents
Although currently not approved by the US Food and Drug Administration (FDA) for cardiac imaging, the vast majority of cardiovascular magnetic resonance (CMR) studies use a gadolinium-based contrast agent. The…
Basic Principles of Cardiovascular Magnetic Resonance
Introduction This introduction to the basic principles of cardiovascular magnetic resonance (CMR) describes the concepts of magnetization, T1, T2, T2*, and image formation, and describes some common CMR pulse sequences…
Techniques for T1, T2, and Extracellular Volume Mapping
Many disease processes alter the local molecular environment of the myocardium, and consequently the longitudinal (T1) and transverse (T2) relaxation times can change. While such changes may be observed directly…
Fleischner Society Glossary of Terms for Thoracic Imaging
Fleischner Society Glossary of Terms for Thoracic Imaging 25.1 Preliminary Remarks The Fleischner Society is an international society for thoracic radiology, founded in 1969 to provide a forum for the…
Diffuse Parenchymal Lung Diseases
Diffuse Parenchymal Lung Diseases A systematic approach to differential diagnosis of diffuse parenchymal lung diseases based on the radiologic findings is given in Chapter 24. Diffuse parenchymal lung diseases are…
Treatment-Related Changes
Treatment-Related Changes 17.1 The Postoperative Thorax 17.1.1 Partial Lung Resection Surgical Techniques Partial lung resection is performed for therapeutic and, less commonly, also for diagnostic purposes: Diagnostic resection: This is…
Tumors of the Lung
Tumors of the Lung 9.1 Hamartoma Hamartomas (synonyms: chondroid hamartoma, chondromatous hamartoma, chondrohamartoma, hamartochondroma, chondroma) are the most common type of benign lung tumor and account for 8% of all…
