Synopsis

Keywords: Tumors, Tumor, MetastasisWe compared standard T1-weighted thin-slice SE and T1-weighted SPACE sequences in the detection of metastatic brain lesions at 1.5 and 3 Tesla in 56 patients. Three raters evaluated the presence of lesions in 2 sessions minimally 6 weeks apart. Our results show that T1-weighted SPACE is not inferior to standard thin-slice SE sequences in the detection of brain metastases. All three experienced raters reached excellent consistency between SE and SPACE and agreement with ground truth.
