摘要 目的探讨高场磁共振全身弥散加权成像(WB-DWI)技术对恶性肿瘤骨转移的诊断价值。方法利用我院1.5T超导磁共振对22例恶性肿瘤骨转移的患者,同期行WB-DWI扫描及ECT检查,二者进行比对,以此来分析WB-DWI对病灶的检出率与准确率。结果 22例恶性肿瘤骨转移患者中,经临床及综合影像确认骨转移灶180个;WB-DWI检出骨骼异常信号灶159个,其中假阳性6个,遗漏真阳性病灶27个,检出率85%,准确性96.23%;核素骨扫描检出骨骼系统异常放射性浓聚灶175个,其中假阳性15个,遗漏真阳性病灶20个,检出率88.89%,准确性91.14%。结论 WB-DWI与核素骨扫描对骨转移瘤的诊断差异无统计学意义,并且其检查简便易行、费用低廉、无辐射损伤,可作为恶性肿瘤骨转移的筛查手段。
