简介
Purpose
To conduct a prospective comparison of the accuracy of whole‐body MR imaging and positron emission tomography (PET) with fluorine‐18 deoxyglucose (FDG) (FDG‐PET) to assess the M‐stage in lung cancer patients.
Materials and Methods
A total of 90 consecutive lung cancer patients (mean age = 68 years) underwent whole‐body MR imaging and FDG‐PET as well as other standard radiological imaging procedures before and after treatment. Probabilities of metastases on whole‐body MR imaging and FDG‐PET were assessed by using 5‐point scoring systems on a per‐site basis and on a per‐patient basis. Receiver operating characteristic (ROC) curve analysis was used to compare diagnostic capabilities. Sensitivity, specificity, and accuracy were also compared by using the McNemar's test on a per‐site and per‐patient basis.
Results
For assessment of head and neck metastases and bone …
