Noncontrast and Contrast-Enhanced Pulmonary Magnetic Resonance Angiography,ecting the pulmonary arteries. Some clinical sites are already using this method for the primary assessment of pulmonary embolism in younger patients. The advantages of CE-MRA over Computed Tomographic Angiography (CTA), in the assessment of the pulmonary vasculature, are: (1) lack of ionizing radia

Hyperpolarized 129Xenon MRI of the Lung,ontains tissue or blood while the remainder is filled with air. By comparison, most of the volume in other organs is hydrogen. Another source of the inherently weak MR signal in the lungs is the extremely large area of the tissue-gas interface. The 3 ppm difference in magnetic susceptibility between

Dynamic MRI of Respiratory Mechanics and Pulmonary Motion,ngly appreciated in clinical imaging and research. Dynamic MRI accelerated by parallel imaging and echo sharing reaches temporal resolutions of up to ten images per second in single plane acquisitions or one volume per second in time-resolved 3D imaging. Recently developed, externally, navigator- or
