Widespread bone metastases can occasionally give rise to a uniform distribution of 99Tcm methylene diphosphonate resulting in a superficially normal appearance on the bone scan. The scans are recognizable by the high ratio of bone to soft tissue activity, the absence of focal lesions in the axial skeleton, and there are usually no renal images. These "superscans" can occasionally be misinterpreted as normal. An index of image quantitation related to the ratio of bone to soft tissue uptake is shown to be capable of clearly distinguishing these patients from patients in other categories. The condition is thought to be more frequently associated with prostatic carcinoma than with other aetiologies.
广泛的骨转移偶尔可导致99锝亚甲基二膦酸盐均匀分布，从而在骨扫描上呈现出表面正常的外观。这些扫描可通过骨与软组织活性的高比值、中轴骨骼无局灶性病变以及通常无肾脏影像来识别。这些“超级骨显像”偶尔可能被误诊为正常。与骨与软组织摄取比值相关的图像定量指标显示能够清晰地区分这些患者与其他类型的患者。这种情况被认为与前列腺癌的关联比与其他病因更为常见。
