To compare the results obtained with 99mTc-sestamibi and gated-SPECT (gated SPECT in stress and rest) with 201Tl (stress, redistribution, and 24 hour reinjection SPECT).
Twenty patients underwent two SPECT studies, one with 201Tl and the other with 99mTc-sestamibi.
Using 201Tl as a reference, 177 segments were considered normal, 31 viable and 32 with myocardial necrosis. The overall concordance with 99mTc-sestamibi was 84.2%. In the subgroup of defects that improved after reinjection of 201Tl, it was much less (45%), even after wall thickness and movement (55%) were analyzed.
The overall concordance between 201Tl scintigraphy compared to 99mTc-sestamibi is acceptable. Correlation is low in the viable segments with 99mTc-sestamibi, even after analyzing the Gated-SPECT.
比较99m锝-司他米比和门控单光子发射计算机断层扫描（静息和负荷状态下的门控单光子发射计算机断层扫描）与铊-201（负荷、再分布及24小时再注射单光子发射计算机断层扫描）的检查结果。
20例患者接受了两项单光子发射计算机断层扫描检查，一项使用铊-201，另一项使用99m锝-司他米比。
以铊-201作为参照，177个节段被视为正常，31个节段存活，32个节段存在心肌坏死。99m锝-司他米比的总体符合率为84.2%。在铊-201再注射后缺损改善的亚组中，符合率更低（45%），即便分析了室壁厚度和运动情况后（符合率为55%）依然如此。
铊-201闪烁扫描与99m锝-司他米比之间的总体符合率尚可。即便分析了门控单光子发射计算机断层扫描结果，99m锝-司他米比在存活节段中的相关性仍较低。
