The Effect of Contrast Dose, Imaging Time and Lesion Size in the MR Detection of Intracerebral Metastasis AJNR 16:373-380, Yuk,W.T.C.,et al, 1995 See this aricle in Pubmed Article Abstract To evaluate the effect of MR contrast dose versus delayed imaging time on the detection of metastatic brain lesions based on lesion size.Contrast MR examinations with gadoteridol were obtained in 45 patients with brain metastases.The patients were divided into two groups:16 received cumulative standard dose(0.1 mmol/kg)and 29 received cumulative triple dose(0.3 mmol/kg).In the evaluation of small central nervous system metastases,either delayed imaging after the injection of standard contrast dose or higher contrast dose may improve their detection,and therefore affect clinical management.Higher contrast dose(cumulative triple dose) studies appear to be more effective than delayed imaging with standard dose.
