Contrast enhanced MRI is known to be optimal for detection of brain metastasis with high sensitivity and specificity. In recent MR studies, double- or triple-dose Gd-contrast administration was found to be effective in accurate localization of metastasis without any complications. Gadobutrol is the first commercially available 1.0M Gd contrast. With its higher Gd concentration in plasma, gadobutrol increases signal of enhanced lesions and raised diagnostic rate in brain tumors and metastasis. The purpose of this study was to compare the diagnostic efficacy of 1.5T with double dose 1.0M gadobutrol in detection of brain metastasis comparing with 3.0 T with double-dose 0.5M Gd-DTPA.
