Synopsis

Keywords: Lung, Cancer, unbalanced steady state free precessionCardiovascular MR is an invaluable diagnostic tool for the heart and great vessels. As with cardiac CT, it is imperative to carefully evaluate areas outside of the heart to exclude the presence of clinically relevant lesions such as pulmonary infiltrates or lung cancer. Unfortunately, existing CMR techniques are grossly inadequate for detecting and characterizing extra-cardiac lesions. We hypothesized that prototype volumetric dark blood SSFP techniques could overcome these limitations and tested them in patients undergoing CMR. In this pilot study, dark blood SSFP outperformed standard CMR techniques for the evaluation of incidental pulmonary lesions, including benign nodules and cancer.
