“…Diagnostic confidence increased using CTAC as 80% of scans were interpreted as normal or abnormal, rather than equivocal, versus 57% of scans without AC (P \ 0.001). 22 Caobelli et al looked at 60 patients, 44 of which underwent coronary angiography, to compare the performance of CZT with and without CTAC. Interestingly, the authors found significantly improved diagnostic accuracy in the RCA territory (P = 0.002) but not in the LAD (P = 0.35) or LCx (P = 0.08) territories.…”
