一般恶性肿瘤骨转移灶在核素骨显像图上呈现全身多发性、非对称性放射性浓聚区。然而,骨转移病灶呈放射性稀疏区(以下简称“冷区”)也是其骨显像图中的一种表现。本文对14例以“冷区”为表现的恶性肿瘤骨转移图像进行分析,以探讨其产生机制及临床意义。一、资料与方法从我院1993年～1996年的515份全身核素骨显像图中,查出14例以“冷区”为表现的临床确诊为恶性肿瘤骨转移的患者,均伴有放射性浓聚区。其中,男10例,女4例,年龄30～68岁,

The malignant tumor bone metastases showed a systemic multiple and asymmetric radioactive concentrating area on the nuclide bone imaging. However, bone metastatic lesions are sparsely radioactive areas (hereinafter referred to as “cold area”), which is also a manifestation of bone imaging. In this paper, 14 cases of malignant tumor bone metastases expressed as “cold area” were analyzed to explore its production mechanism and clinical significance. I. Materials and Methods From 515 systematic radionuclide bone scans of our hospital from 1993 to 1996, 14 patients with clinical manifestations of malignant tumor bone metastases who were diagnosed with “cold area” were identified. Accompanied by radioactive concentrated area. Among them, there were 10 males and 4 females aged 30-68 years.
