核素骨显像胸骨单发浓聚灶特点分析

目的探讨核素全身骨显像胸骨单发浓聚灶的特点及联合CT诊断的临床意义。方法收集本院近7个月全身骨显像中发现的胸骨单发浓聚灶42例,并行胸骨局部CT检查。按核素浓聚灶位置、形状及CT影像表现进行诊断分析。结果 42例胸骨单发浓聚灶患者中有骨转移瘤37例(占88.1%),退行性变3例,手术创伤2例。胸骨单发浓聚灶胸骨体多见(28处),其次是胸骨柄(16处)和诸切迹(5处),形状以团块状为主。结论核素骨显像胸骨单发浓聚灶联合CT有助于对胸骨病变明确诊断,具有重要临床价值,值得推广应用。

Analysis of Sternal Single Uptake on Bone Scintigraphy

Objective To explore the features of sternal single uptake on bone scintigraphy and to investigate the value of bone scintigraphy combined with CT in the diagnosis of sternal single uptake.Methods 42 patients with sternal single uptake in recent seven months were involved in the study,and CT scans of the sternum were also performed.The images of sternal lesion were analyzed according to the site,shape and the CT manifestation of the lesion.Results Among the 42 patients with sternal single uptake,37 cases had bone metastases(88.1%),3 cases had joint degeneration and 2 cases had surgical traumas.The sterna single uptake were mainly in the body of sternum(28 lesions),manubrium(16 lesions) and incisure(5 lesions),mostly in the shape of mass.Conclusion Single uptake in sternum can be diagnosed by bone scintigraphy combined with CT,which has important clinical value and should be promoted.
