COMPARATIVE STUDY OF MAGNETIC RESONANCE IMAGING AND COMPUTED TOMOGRAPHY ON THE EVALUATION OF MEDIASTINAL INFILTRATION OF PRIMARY LUNG CANCER
Forty patients suspected of mediastinal involvement of primary lung cancer were studied prospectively using magnetic resonance imaging (MRI) and computed tomography (CT). The patients consists of squamous cell carcinoma (n＝20), adenocarcinoma (n＝14), large cell carcinoma (n＝3) and small cell carcinoma (n＝3). MRI has advantage in contrast resolution, sagittal and coronal images, and in great intrinsic contrast resolutin of large vessels. Spatial resolution of MRI, however, is currently not equal to that of CT and is hampered by respiratory motion. MRI discriminated mediastinal tumor infiltration from the atrium and pulmonary artery more accurately than CT but tumor infiltrations to the SVC and aorta were not evaluated properly by MRI for its poor spatial resolution. It is concluded that for the proper evaluation of tumor infiltration to mediastinal organs, both MRI and CT are valuable and complementary to each other.
