Check the chest: review of chest findings on abdominal MRI

Magnetic resonance imaging (MRI) of the abdomen may include lower chest findings which may be overlooked or misinterpreted due to their location outside the area of main exam focus or lack of familiarity with the image appearance of these findings. This article will review the utility of abdominal MRI sequences to diagnose lower chest pathology while providing a systematic pictorial review of imaging findings in the lungs, pleura, mediastinum and chest wall. We will discuss the MRI appearance of lung nodules and masses, lung infiltrates, pulmonary infarction, pulmonary embolism, empyema, pleural effusions and thickening, mediastinal lesions and lymphadenopathy, cardiac thrombus and masses, and breast lesions. The purpose of this article is to increase awareness to the diagnostic advantages of abdominal MRI sequences for lower chest findings and encourage abdominal MRI readers to meticulous scrutinize the lower chest for concomitant pathology.
