Assessment of whole-body MRI including diffusion-weighted sequences in the initial staging of breast cancer patients at high risk of metastases in comparison with PET-CT: a prospective cohort study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe aim of this study was to assess the diffusion-weighted whole-body-MRI (WBMRI) in the initial staging of breast cancer at high risk of metastases in comparison with positron emission tomography (PET)-CT.
methodsForty-five women were prospectively enrolled. The inclusion criteria were female gender, age >18, invasive breast cancer, an initial PET-CT, and a performance status of 0-2. The exclusion criteria were contraindication to WB-MRI and breast cancer recurrence. The primary outcome was the concordance of WB-MRI and PET-CT in the diagnosis of distant metastases, whereas secondary outcomes included their concordance for the primary tumor and regional lymph nodes (LN), as well as the agreement of WB-MRI interpretation between two radiologists.
resultsThe mean age was 51.2 years with a median size of the primary tumor of 30 mm. Concordance between the two modalities was almost perfect for metastases staging, all sites included (k = 0.862), with excellent interobserver agreement. The accuracy of WB-MRI for detecting regional LN, distant LN, lung, liver, or bone metastases ranged from 91 to 96%. In 2 patients, WB-MRI detected bone metastases that were overlooked by PET-CT. WB-MRI showed a substantial agreement with PET-CT for staging the primary tumor, regional LN status, and stage (k = 0.766, k = 0.756, and k = 0.785, respectively) with a high interobserver agreement.
conclusionWB-MRI including DWI could be a reliable and reproducible examination in the initial staging of breast cancer patients at high risk of metastases, especially for bone metastases and therefore could be used as a surrogate to PET-CT. CLINICAL RELEVANCE STATEMENT: Whole-body-MRI including DWI is a promising technique for detecting metastases in the initial staging of breast cancer at high risk of metastases. KEY POINTS: Whole-body-MRI (WB-MRI) was effective for detecting metastases in the initial staging of 45 breast cancer patients at high risk of metastases in comparison with PET-CT. Concordance between WB-MRI and PET-CT was almost perfect for metastases staging, all sites included, with excellent interobserver agreement. The accuracy of WB-MRI for detecting bone metastases was 92%.
