MSCT多平面重组和血管造影在肝脏巨大肿块诊断中的价值

摘要

Objective: To investigate the application of multi-slice spiral CT (MSCT) multiplanar reformation (MPR) and angiography (CTA) in diagnosis of huge hepatic tumor. Methods:Collected 15 cases of patients with liver, multiple CT enhanced scanning. Slice thickness 1.0mm, pitch 1.0mm scanning. With the thickness of 0.625mm, 0.625mm space reconstruction, axial source images (ASI) data were transferred to workstation. Vascular arterial phase data MIP, VRT reconstruction, MPR reconstruction in venous phase data, diagnostic value of MPR, CTA and MPR+CTA. Results:7 cases of qualitative MPR, CTA according to the arterial and tumor staining to identify benign and malignant 8 cases, no significant differences in qualitative diagnosis of the contrast of the two (P>0.05), MPR+CTA qualitative analysis in 13 cases, there was significant difference compared with the former two (P<0.05).Conclusion:MPR, CTA technology as a non-invasive examination means, it is helpful to diagnosis of huge hepatic tumor, but MPR+CTA has diagnostic value, can provide help for the clinical treatment plan reasonable and effective.%目的：探讨多层螺旋CT(MSCT)多平面重组技术(MPR)及血管造影(CTA)对肝脏巨大肿块的诊断价值。方法：收集15例肝脏患者,行多期CT增强扫描。层厚1.0mm、间距1.0mm扫描。采用0.625mm层厚、0.625mm间距进行重建,轴面源图像(ASI)数据传至工作站。血管动脉期数据行MIP、VRT重建,静脉期数据行MPR重建,分析MPR、CTA及MPR+CTA的诊断价值。结果：MPR定性7例,CTA根据供血动脉的多少及肿块染色确定良恶性8例,对比两者定性诊断无显著差异(P>0.05),MPR+CTA定性13例,与前两者比较有显著差异(P<0.05)。结论：MPR、CTA技术作为无创伤的检查手段,都有助于肝脏巨大肿块的诊断,但MPR+CTA有更高的诊断价值,能为临床制定合理有效的治疗方案提供帮助。
