摘要
目的探讨64层螺旋CT多期增强扫描对小肾癌的诊断价值。方法回顾性分析23例经手术或活检证实的小肾癌的螺旋CT资料及病理结果。结果 CT平扫中8例为等密度,14例为略低密度,1例为囊实性混杂密度。增强扫描皮质期18例强化程度高于或相当于正常肾皮质,3例强化低于肾皮质但高于肾髓质,1例强化程度等于肾髓质,1例囊实性病例囊壁明显强化。肾实质期扫描23例均显示肿瘤强化迅速减退,肾盂期扫描肿瘤密度进一步减退。结论多层螺旋CT多期增强扫描对小肾癌的诊断是可靠有价值的诊断方法,特别是小肾癌皮质期强化明显,实质期强化迅速减退,呈"快进快出"表现,有重要的定性意义。
Objective To study the diagnostic value of multi-phase multislice helical CT scan in small cell carcinoma.Methods The CT scan datum and pathologic findings of 23 patients pathologically proved small renal cell carcinomas were retrospective analyzed.Results 8 patients CT showed isodense,14 with sligthtly hypodense,and 1 with cyst and solid mass.After administration of contrast media,in cortical phase the tumor was enhanced,combined with higher and the same degree to the cortex in 18 SRCCs,with lower degree to the cortex but higher degree to the medullary in 3 SRCCs,with the same degree to the medully in 1 SRCCs In cortical phase the cyst wall showed marked enhacement in the cyst and solid case.In parenchymal phase the tumor density drops promptly,and in the pelvic phase the tumor density drops further.Conclusion The multi-phasic spiral CT scan is valuable in the diagnosis of small renal cell carcinoma.In most patients tumor enhacement was marked in cortical phase but less in parenchymal phase,the phenomenon of"quick staining and quick fainting"which is a characteristic pattern of enhancement is significant in diagmosis of small renal cell carcinoma.
