本文对2例恶性淋巴瘤大面积心肌侵犯患者的铊-201心肌灌注显像进行了临床病理分析。尽管有广泛的肿瘤浸润，但其中一名患者的铊闪烁图显示正常，而另一名患者只有一个中等大小的示踪剂摄取减少的区域。这些患者的铊扫描结果与死后观察结果之间的差异可能与肿瘤细胞对铊的摄取有关。任何细胞和灌注良好的组织吸收钾和钾类似物（如铊）的能力表明，铊-201闪烁显像可能不是筛查已知恶性肿瘤患者心脏病变的有用方法。
A clinicopathologic correlation was made of thallium-201 myocardial perfusion imaging in two patients with massive myocardial invasion by malignant lymphoma. Despite extensive tumor involvement, the thallium scintigram was normal in one patient, while the other had only a modest-sized region of reduced tracer uptake. The discrepancy between the results of thallium scans and postmortem observations in these patients is probably related to uptake of thallium by tumor cells. The ability of any cellular and well-perfused tissue to absorb potassium, and potassium analogs such as thallium, suggests that thallium-201 scintigraphy may not be a useful method to screen for cardiac involvement in patients with known malignant neoplasms.
