Synopsis

Keywords: Cardiovascular: Myocardium, Image acquisition: Quantification

Quantitative myocardial perfusion imaging is increasingly being used clinically as a valuable tool for improved detection of perfusion defects arising from coronary artery disease as well as microvascular disease. A number of frameworks exist for performing quantitative perfusion imaging with combinations of different (i) data acquisition and reconstruction schemes, (ii) post-processing methods and (iii) modeling approaches. The presentation will give an overview of methods used in each of the three major steps.

Quantitative myocardial perfusion imaging is increasingly being used clinically as a valuable tool for improved detection of perfusion defects arising from coronary artery disease as well as microvascular disease [1-3]. A number of frameworks exist for performing quantitative perfusion imaging with combinations of different (i) data acquisition and reconstruction schemes [4-12], (ii) post-processing methods [13-15] and (iii) modeling approaches [16-18]. The presentation will give an overview of methods used in each of the three major steps including (i) dual-bolus [7], dual-sequence [4, 19] and non-cartesian acquisitions [6, 10, 20] (ii) semi-automated and automatic motion compensation [13] and segmentation methods [21, 22] (iii) Two-compartment [17], Fermi [23], Blood Tissue Exchange (BTEX) [18] models.
