Twenty normal subjects and ten patients with pericardial abnormalities underwent ECG-gated magnetic resonance (MR) imaging of the thorax using a 0.35-tesla superconducting system. The patients with pericardial abnormalities were also evaluated with serial chest radiographs, ultrasound, computed tomography, and/or angiography. ECG gating was necessary to identify the normal pericardium, which was visualized as a 1- to 2-mm-wide curvilinear structure of low signal intensity. Pericardial thickening in constrictive pericarditis was clearly delineated on gated MR images. Pericardial inflammation caused a marked increase in signal intensity as well as thickening of the pericardium. Pericardial effusions and pericardial adhesions were also demonstrated. A simple pericardial cyst and a complex pericardial mass were identified and differentiated from pericardial fat and diaphragmatic eventration. MR appears to be an important modality for the evaluation of pericardial disease.
20名正常受试者和10名心包异常患者使用0.35特斯拉超导系统进行了胸部心电图门控磁共振(MR)成像。心包异常患者还接受了系列胸部X线片、超声、计算机断层扫描和/或血管造影检查。心电图门控对于识别正常心包是必要的,正常心包表现为1至2毫米宽的低信号强度曲线结构。缩窄性心包炎的心包增厚在门控MR图像上清晰可见。心包炎症导致信号强度显著增加以及心包增厚。还显示了心包积液和心包粘连。识别出一个简单的心包囊肿和一个复杂的心包肿块,并将其与心包脂肪和膈膨出区分开来。MR似乎是评估心包疾病的一种重要方式。
