Dual radionuclide subtraction imaging of the spleen using 67Ga citrate and 99mTc is useful in further delineating lesions that are identified on either a routine radiogallium survey or on a conventional sulfur colloid liver-spleen image. Better anatomic localization of left subphrenic abscesses may be obtained. Differentiation of tumors and abscesses from less serious lesions such as cysts, infarcts, and hematomas is possible. We have found this technique to be generally applicable to any organ that can be selectively imaged using a technetium radiopharmaceutical, including the liver, bones, and kidneys. In addition, we are currently evaluating thallium-pertechnetate subtraction imaging in the evaluation of parathyroid adenomata.
使用枸橼酸镓67和锝99m对脾脏进行双放射性核素减影成像，有助于进一步明确在常规放射性镓扫描或传统硫胶体肝脾图像上发现的病变。可以更好地对左膈下脓肿进行解剖定位。能够区分肿瘤和脓肿与囊肿、梗死和血肿等不太严重的病变。我们发现这项技术通常适用于任何能用锝放射性药物进行选择性成像的器官，包括肝脏、骨骼和肾脏。此外，我们目前正在评估高锝酸盐铊减影成像在甲状旁腺腺瘤评估中的应用。
