多层螺旋CT对脾实性肿瘤的诊断价值

目的评价多层螺旋CT对脾实性肿瘤的诊断价值。资料与方法回顾性分析16例经病理、穿刺或手术证实的脾实性肿瘤患者的CT资料,分别由2名放射科医师采用双盲法对病灶的CT征象进行分析,最后统一意见判断其良、恶性。采用Fisher精确校正检验及t检验进行统计学分析。结果脾良、恶性肿瘤的大小、数目、形态及脾有无肿大无统计学差异(P>0.05),但患者症状、病灶有无环形强化及腹腔或后腹膜淋巴结有无肿大有统计学差异(P<0.05)。CT对良恶性诊断结果进行统计学分析,P<0.05,差异具有统计学意义。CT鉴别脾良、恶性肿瘤的敏感度、特异度、阳性预测值、阴性预测值分别为77.8%、85.7%、87.5%、75.0%。结论多层螺旋CT具有鉴别脾良、恶性肿瘤的诊断价值,使一些良性肿瘤患者避免不必要的切脾手术,帮助淋巴瘤患者及早明确治疗。

Multidetector CT Diagnosis Of Splenic Solid Tumors

Objective To discuss the role of Multi-detector CT in the evaluation of splenic solid tumors.Materials and Methods CT findings of 16 patients with splenic solid tumors confirmed by histopathology,biopsy or surgery were retrospectively analyzed,and also double-blinded reviewed by two radiologists.Statistical analysis were evaluated by Fisher exact test and paired t test.Results There were no significant difference in size,number and pattern of tumors as well as spleen size(P>0.05),while subject's symptoms,ri...
