| 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 explore the imaging features and clinical significance of solitary costal hot spots on bone scintigraphy (BS). Methods Eighty-four patients with single costal hot spots were enrolled in the study. The sites of lesions were classified into four types: junction between costal cartilage and rib, frontal rib, lateral rib and posterior rib. The shapes of hot spots were classified into three forms: Punctiform, clumping and strip. The above data were respectively analyzed. Results Single hot spots were mainly showed in the punctiform and strip shapes, and the distribution of punctiform spots were mainly in the sites of junction between costal cartilage and rib and frontal ribs, also mainly due to costal fractures (42/61, 68.85%). The majority of spots in strip shape were costal metastases(18/19, 94.74%). Hot spots in posterior ribs were also mainly costal metastases (24/29,82.76%). Conclusion Useful imaging features can be obtained from BS with single costal hot spots, being helpful to differential diagnosis of benign and malignant lesions. |
