Objective To evaluate the value of dynamic contrast enhancement MRI in the diagnosis of pituitary micro-adenomas.
目的评价磁共振动态增强扫描诊断垂体微腺瘤的价值。
MRS can differentiate the nature of the lesions, and can improve the diagnostic specificity combined with dynamic contrast enhancement MRI.
MRS能够区分病变性质，与动态对比增强扫描联合应用能够提高诊断的特异性。
The parameters for evaluation in dynamic contrast enhanced MRI included early enhancement rate, time signal intensity curve pattern and lesion's morphological features.
动态资料的评价参数包括：早期增强率、时间信号强度曲线类型以及病变的形态学特征。
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.
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。
