摘要: 研究少血供和富血供肝转移瘤螺旋CT双期表现。 12 8例肝转移瘤行螺旋CT全肝双期扫描 ,扫描后图象重建。扫描结果 98例为少血供 ,30例为富血供。结果证实螺旋CT双期扫描动脉期有利于富血供病灶的检出 ,门静脉期易于少血供的转移瘤检出。双期扫描提高了肝转移瘤的检出率 ,对于肝转移瘤的定性和鉴别诊断有很重要意义Abstract: Study spiral CT dual-phase appearance for rich blood supply and less blood supply hapatic metastases.128 cases hapatic metastasis were scaned by spiral CT whole liver dual-phasescans.Image was reconstracted after CT scans, 98 cases were less blood supply, 30 cases were rich blood supply.Spiral CT dual-phase scans aterial phase help to detect rich blood lesion.And portal vein phase help to detect less blood supply metastasis.dual-phase scans improve hapatic metastases detecting rate.There is important signification for detecting and differential diagnosis of hapatic metastasis.
