The clinical performance of the planar vs. tomographic ergometric stress 201-Tl myocard perfusion scintigraphy was compared. The results of the investigations of 80 patients were analysed retrospectively. In 59 patients planar, in 21 tomographic imaging was performed. As a consequence of clinical decision making cardiac catheterization was made in all of the patients, within 3 months after the perfusion scintigraphy. The sensitivity of the planar method was 23/27 (85%), the specificity 18/32 (56%), the accuracy 41/59 (69%). The respective values of the SPECT technique were: Sensitivity: 12/12 (100%), specificity 6/9 (66%), accuracy 18/21 (86%). It is concluded, that in comparison to the planar imaging the SPECT technique is superior in the detection of the perfusion abnormalities of the myocard due to significant coronary narrowings.
对平面与断层运动负荷201-Tl心肌灌注闪烁显像的临床性能进行了比较。对80例患者的调查结果进行了回顾性分析。59例患者进行了平面显像，21例进行了断层显像。由于临床决策，所有患者在灌注闪烁显像后3个月内均进行了心导管检查。平面法的敏感性为23/27（85%），特异性为18/32（56%），准确性为41/59（69%）。SPECT技术的相应值为：敏感性：12/12（100%），特异性6/9（66%），准确性18/21（86%）。得出结论，与平面显像相比，SPECT技术在检测由于明显冠状动脉狭窄导致的心肌灌注异常方面更具优势。
