An example of aneurysmal concentration of 99mTc-pyrophosphate (Tc-PPi) is described. An abdominal aortic aneurysm was suspected when a rectilinear bone scan showed an abnormal paraspinal area of activity. The aneurysm was confirmed by ultrasonic examination. Conventional radiographic examination failed to reveal calcification within the aneurysm. Aneurysmal concentration of Tc-PPi should be considered in patients showing abnormal radioactivity in the region of vascular structures on radionuclide bone images.
本文描述了一例99m锝-焦磷酸盐（Tc-PPi）在动脉瘤处浓聚的病例。当直线型骨扫描显示脊柱旁异常放射性浓聚区时，怀疑存在腹主动脉瘤。经超声检查确诊为动脉瘤。传统X线检查未发现动脉瘤内有钙化。对于放射性核素骨显像上血管结构区域出现异常放射性的患者，应考虑Tc-PPi在动脉瘤处的浓聚情况。
