Chemical exchange saturation transfer (CEST) imaging is suggested as new technique and one of the MR-based molecular imaging techniques. However, no major reports have been published for evaluating clinical utility of CEST imaging in thoracic oncology patients. We hypothesized that newly developed CEST imaging is possible to evaluate thoracic nodule and mass, and play as new diagnostic tool in routine clinical practice. The purpose of this study was to determine the capability of CEST imaging for characterization of thoracic nodule and mass, and evaluate a potential as a new MR-based molecular imaging method in thoracic oncology.
