皮质醇增多症磁共振成像分析

The Analysis of Magnetic Resonance Image of Hypercortisolism

目的探讨皮质醇增多症患者的磁共振检查表现。方法选取20例皮质醇增多症患者,将磁共振检查方法与MRI表现进行分析。结果肾上腺皮质增生病变信号与正常肾上腺基本相同,故MRI诊断主要看形态。肾上腺腺癌形态学表现与CT相似,但信号改变有特点。结论 MRI为成肾上腺高质量的影像,多作为CT的补充检查。特别是MRI可获得冠状切面成像,有利于分辨肾上腺与肾上极的病变;病变的MR信号特征可助于某些病变(如血肿)的定性诊断。

Objective The magnetic resonance manifestation of patients with hypercortisolism is to be investigated. Methods Analyzing the magnetic resonance manifestation and MRI manifestation of 20 cases of patients with hypercortisolism. Results The adrenal hyperplasia signal was substantially identical with the normal one, therefore, the diagnosis of MRI was basically about the feature. The morphological features of adrenal carcinoma wea similar to that of CT, but the signal changes particularly. Conclusion As the high-quality image of adrenal glands, MRI is taken as a supplement to CT examination. Especially that the coronal-shape image is available in MRI which is conducive to distinguishing adrenal lesions from kidney pole lesions; pathological changes in signal characteristics of MR could be helpful to diagnose some illness（e.g. hematoma）.
