PURPOSE: To compare image contrast and lesion conspicuity of enhancing intracranial lesions obtained with T1-weighted and magnetization transfer T1-weighted spin-echo sequences after administration of standard (0.1 mmol/kg body weight) and triple doses of gadobutrol. METHODS: Twenty-four patients with a total of 34 enhancing intracranial lesions were studied with T1-weighted and magnetization transfer T1- weighted spin-echo MR imaging. An incremental dose technique was used with intravenous injections of 0.1 and 0.2 mmol/kg body weight gadobutrol. Lesion-to-white matter contrast and white matter-to-edema contrast were calculated. RESULTS: The lesion-to-white matter contrast of the magnetization transfer T1-weighted studies was significantly higher than that of the T1-weighted studies when identical doses of gadobutrol were compared. The lesion-to-white matter contrast was not significantly different on the triple-dose T1-weighted study and the standard-dose magnetization transfer T1-weighted study. Two lesions were visible only on the standard-dose magnetization transfer T1- weighted and the triple-dose studies. CONCLUSION: Standard-dose magnetization transfer T1-weighted and triple-dose T1-weighted spin- echo MR studies are equally well suited to increase the lesion-to-white matter contrast in patients with enhancing intracranial lesions. Triple- dose magnetization transfer T1-weighted studies further increase lesion- to-white matter contrast but do not show additional lesions. This article has been cited by other articles: B.
