To determine the value of inclined coronal MR in diagnosing thoracic abnormalities, the multiscan coronal and inclined coronal spin echo MR images of 4 normal subjects and 10 patients with thoracic abnormalities were reviewed. The major airway such as trachea, main bronchi and lobar bronchi, left atrium and its junctions with pulmonary veins required less slices for visualization on inclined coronal images than on standard coronal images, and these normal structures and the lesions located in this region were easy to evaluate in several cases. The left pulmonary artery, especially the upper and lower lobe branches were better visualized on inclined coronal images. The pericardium and the other great vessels were equally visualized on inclined and on standard coronal images. There was no case in which normal structures or lesions were more difficult to demonstrate on inclined coronal images compared with standard coronal images. We conclude that an inclined coronal MR scan of the thorax is valuable to evaluate the mediastinal structures and lesions, especially in diagnosing the abnormalities of the airway, left atrium and its junctions with pulmonary veins.
为了确定斜冠状面磁共振成像（MR）在诊断胸部异常中的价值，我们回顾了4名正常受试者和10例胸部异常患者的多层面冠状面和斜冠状面自旋回波MR图像。与标准冠状面图像相比，气管、主支气管和叶支气管等主要气道、左心房及其与肺静脉的连接处，在斜冠状面图像上显示所需的层面较少，在某些病例中，这些正常结构以及位于该区域的病变易于评估。左肺动脉，尤其是上叶和下叶分支，在斜冠状面图像上显示得更好。心包和其他大血管在斜冠状面和标准冠状面图像上显示相同。与标准冠状面图像相比，没有一例正常结构或病变在斜冠状面图像上更难显示。我们得出结论，胸部斜冠状面MR扫描对于评估纵隔结构和病变是有价值的，尤其是在诊断气道、左心房及其与肺静脉连接处的异常时。
