- W2077946413 abstract "The present study aimed to investigate the diagnostic value of Flash dual‑source CT coronary angiography (DS‑CTA) combined with dual‑energy myocardial perfusion imaging (DS‑CTP) for coronary heart disease (CHD), as a single‑stage examination. A total of 60 patients with CHD underwent DS‑CT examination, as well as coronary angiography (CAG), as the reference standard. The patients were divided into <50% and ≥50% stenosis groups based on their coronary angiograms. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of the method for diagnosing stenosis of ≥50% were evaluated via DS‑CTA combined with DS‑CTP. Of the 60 patients, 59 showed satisfactory results that conformed to the diagnostic requirements. Using CAG as the reference standard, the sensitivity, specificity and positive and negative predictive values of the Flash DS‑CT results in the ≥50% vascular stenosis group were 83.7, 92.7, 88.9 and 89.1%, respectively. The respective values for DS‑CTA combined with DS‑CTP for diagnosing CHD were 94.2, 91.1, 88.0 and 95.8%. Therefore, the results obtained indicate that DS‑CTA combined with DS‑CTP has a high diagnostic value for CHD. DS‑CT is advantageous for diagnosing and prognosticating CHD." @default.
