目的探讨肋骨单发浓聚灶骨显像特点及临床意义。方法选择84例全身骨显像发现肋骨单发浓聚灶病例,将浓聚灶按位置划分为肋骨与肋软骨交界处、前肋、侧肋和后肋四个部位,按浓聚灶形状分为点状、团块状和条形三种,分别进行分析。结果骨显像肋骨单发浓聚灶以点状、条形为主。点状浓聚灶分布以肋骨与肋软骨交界处及前肋居多,多为肋骨骨折(42/61,68.85%);绝大部分条形浓聚灶(18/19,94.74%)为肋骨转移瘤。后肋浓聚灶中,大部分(24/29,82.76%)为肋骨转移瘤。结论良恶性肋骨单发浓聚灶图像具有一定的特征性,有利于鉴别诊断。
Objective To investigate the characteristics and clinical significance of ossification with single ribs. Methods 84 cases of single-concentrated ribs were found by whole-body bone scintigraphy. Concentrated foci were divided into four parts: rib and cartilage junctions, anterior ribs, lateral ribs, and posterior ribs. Three kinds of points, lumps and strips were analyzed separately. Results The single concentrating lesions of bone imaging ribs were mainly punctate and strip. The distribution of punctate concentrating lesions was mostly at the rib and cartilage cartilage junctions and anterior ribs, mostly rib fractures (42/61, 68.85%); most of the strip concentrating lesions (18/19, 94.74%) were rib transfer. tumor. In the posterior rib dense lesions, most (24/29, 82.76%) were rib metastases. Conclusion The image of single concentrating lesions in benign and malignant ribs has certain characteristics and is helpful for differential diagnosis.
