螺旋CT平扫与多期增强扫描检出肝脏实质性占位病变的临床对比研究

目的探讨螺旋CT平扫与多期增强扫描检出肝脏实质性占位性病变对比诊断中的应用价值。方法对螺旋CT和多期增强扫描肝脏实质性占位性病变的图像,分别从对病灶的检出数目、图像显影质量和图像确诊优势这些方面比较两种检查。结果多期增强扫描图像对肝实质性占位性病灶的检出数目53个优于螺旋CT平扫的33个病灶,两组数据差异具有统计学意义(P0.01);螺旋平扫图像质量于多期增强扫描质量,对肿瘤具有增强信息的作用;多期动态增强扫描图像更能对实质性占位性病灶判断其性质,更有利于诊断。结论多期动态增强扫描显影图像质量可得到肝脏和肝脏典型病变多期图像表现特征,能够快速的做出诊断,提高对肝脏实质占位性病临床诊断率,避免误诊发生,可为临床诊治提供影像依据。

Clinical Contrast Study of Spiral CT Scan and Multi-phase Scan on Detecting Liver Space-occupying Lesion

Objective To investigate the application value of spiral CT scan and Multiphase scan on detecting liver space-occupying lesion.Methods Compare the checkout number,image enhancement quality,image confirmed advantage of the images by spiral CT scan and Multi-phase scan on liver space-occupying lesion.Results Checkout number of Multi-phase scan (focus:53) was more than spiral CT scan (focus:33),the difference was statistically significant (P＜0.01).Compared with Multi-phase scan,quality of spiral CT scan can enhance information.Multi-phase scan can better judge character and source compared with spiral GT scan.Conclusion Image quality by Multi-phase scan can obtain image features of liver and liver lesions.It can improve clinical diagnostic rate and avoid misdiagnosis and provide basis.
