Performance of 18F-FDG PET/MRI and 18F-FDG PET/CT for T and N staging in patients with non-small-cell lung cancer

We read with great interest the recent article by Kirchner and colleagues who compared the performance of 18F-FDG PET/CT and 18F-FDG PET/MRI for primary (T) and locoregional lymph node (N) staging in patients with non-small-cell lung cancer (NSCLC) . 18F-FDG PET/CT and 18F-FDG PET/MRI were successively performed at 60 min and 120 ± 16 min after tracer injection, respectively. T and N stages were determined according to the seventh edition of the American Joint Committee on Cancer staging manual . Quantitative agreement between the two methods in terms of the maximum standardized uptake values (SUVmax) and the sizes of the primary tumours was assessed using Bland-Altman plots. The authors concluded that 18F-FDG PET/MRI and 18F-FDG PET/CT show equivalently high performance for T and N staging in patients with NSCLC. However, they recommended that the quantitative assessment of treatment response should be performed on the same equipment (either PET/MRI or PET/CT) to provide...
