This is the second edition of the first available monograph on coronary radiology. In line with recent advances, this edition places special emphasis on the role of non-invasive techniques, detailed information being provided on CT angiography with multidetector and dual-source tomography, 2D and 3D visualization techniques, and MR coronary angiography. Sections on invasive imaging techniques and coronary calcification are included. High-quality color images compliment the text.
