目的：探讨时间延迟分析软件及螺旋自动启动技术在多层螺旋ct腹部增强扫描中的应用价值。
Objective: Study the application of Time Lapse software and spiral Automatic Start technique in Multi-layers spiral ct on abdomen contrast enhancement scanning.
延迟增强扫描费时费力，检出率明显低于动态和常规延迟增强，不适应于常规应用。
Delayed enhanced MRI waste time and strength, rate of lesions detection was inferior to the dynamic and delayed conventional contrast enhancement. It should not be used as routine.
