Additional MR contrast dosage for radiologists’ diagnostic performance in detecting brain metastases: a systematic observer study at 3 T

Conclusions
The double dose improved detection for metastases smaller than 5 mm at 3 T and thus resulted in better diagnostic performance of radiologists. However, a higher dose might result in prolonged reading time and increased false-positives, presumably due to increased vessel signals and frequency of flow-related artifacts.
