Recurrence assessment is important for management of postoperative NSCLC patients. We hypothesized that quick and segmented 3D T1-weighted gradient echo sequence (Quick 3D) and a double fat suppression RF pulse (DFS) technique could improve the diagnostic performance of CE-WB-MRI using a 3T MR system as compared with CE-WB-MRI without Quick 3D and DFS, and might be at least as effective as FDG-PET/CT and conventional radiological examinations in this setting. The purpose of this study was thus to compare diagnostic capabilities for assessment of recurrence of CE-WB-MRI with and without Quick 3D and DFS, PET/CT and conventional radiological examinations.
