From: Quantitative detection of myocardial ischaemia by stress echocardiography; a comparison with SPECT
a-d. Receiver operator characteristics curves of the quantitative perfusion measurements A-, β- and Axβ- reserve in all coronary territories (a), LAD territory (b), LCx territory (c) and RCA territory (d), as compared with ischaemia at SPECT. LAD, left anterior descending; LCx, left circumflex; RCA, right coronary artery; A-r, peak signal intensity reserve; β-r, myocardial blood flow velocity reserve; Axβ-r, myocardial blood flow reserve.
