TNM Staging of Non-Small Cell Lung Cancer: Comparison of PET/MR and PET/CT.

Unlabelled: The purpose of this study was to compare the diagnostic accuracy of whole-body unenhanced PET/MR with that of PET/CT in determining the stage of non-small cell lung cancer.

Methods: This study was approved by the institutional review board and by national government authorities. Forty-two consecutive patients referred for the initial staging of non-small cell lung cancer underwent whole-body imaging with a sequential trimodality PET/CT/MR system.

Whole-body nonenhanced PET/MR versus PET/CT in the staging and restaging of cancers: preliminary observations.

Purpose: To assess the diagnostic performance of whole-body non-contrast material-enhanced positron emission tomography (PET)/magnetic resonance (MR) imaging and PET/computed tomography (CT) for staging and restaging of cancers and provide guidance for modality and sequence selection.

Materials And Methods: This study was approved by the institutional review board and national government authorities. One hundred six consecutive patients (median age, 68 years; 46 female and 60 male patients) referred for staging or restaging of oncologic malignancies underwent whole-body imaging with a sequential trimodality PET/CT/MR system.
