Abstract

BACKGROUND

Whether or not automated scores obtained from myocardial single-photon emission computed tomography (SPECT) imaging using software correlate with the visual interpretations by experts remains obscure.

METHODS AND RESULTS

Eighty-seven consecutive patients with known or suspected angina pectoris underwent (201)thallium stress/rest SPECT followed by coronary angiography and the summed difference scores (SDS) were calculated using Heart Score View software. The SDS was substantially associated with coronary stenosis and accurately detected culprit lesions, because the diagnostic accuracy was comparable to that of expert visual evaluation.

CONCLUSIONS

Automated scores obtained from myocardial SPECT can help detect coronary artery disease.

摘要

背景

心肌单光子发射计算机断层扫描（SPECT）成像的自动评分是否与专家的视觉解释相关仍不清楚。

方法和结果

87 例已知或疑似心绞痛患者连续进行（201）铊应激/静息 SPECT 检查，随后进行冠状动脉造影，并使用 Heart Score View 软件计算总和差评分（SDS）。SDS 与冠状动脉狭窄有显著相关性，并能准确检测到罪犯病变，因为其诊断准确性与专家的视觉评估相当。

结论

心肌 SPECT 的自动评分有助于检测冠状动脉疾病。
