Imaging Effect and Accuracy Analysis of 64-Slice Spiral CT in the Diagnosis of Coronary Artery Stenosis

Objective: To analyze the imaging effect and accuracy of 64-slice spiral CT in diagnosis coronary arterystenosis. Methods: 30 patients with suspected heart disease admitted to our hospital from March 2022 2023 were selected. All underwent both digital subtraction angiography (DSA). DSA is considered gold standard for diagnosis, so it was used diagnostic performance CT. Results: (1) The results analyzed compared each other. had an 96.67% (29/30), a sensitivity 96.55% (28/29), specificity 100.00% (1/1) diagnosing artery stenosis. (2) There no significant difference between positive detection rate anterior descending lesion, left main circumflex lesion right (P > 0.05). (3) examination identifying mild stenosis, moderate severe stenosis arteries Conclusion: can accurately determine degree occlusion arteries, which allows accurate
