In this issue of Radiology, Lennartz and his colleagues (1) evaluate the performance of spectral CT for differentiating between benign pleural lesions and pleural carcinomatosis. They conclude that spectral CT and its derived iodine map improve both quantitative and qualitative determination of pleural carcinomatosis versus noncalcified benign pleural lesions compared with conventional CT. The authors assert that iodine overlay images and quantitative iodine maps substantially improve differentiation of noncalcified benign pleural lesions from pleural carcinomatosis and that the benefit of spectral CT for diagnosis of pleural lesions is greater for less-experienced radiologists than for experienced radiologists.
