To investigate the tolerance of MR examinations in children and adolescents performed in a 1.5 Tesla MR scanner with an expanded bore diameter. ⋯ Pediatric MR imaging using a 1.5 Tesla MR scanner with an open design can be conducted in children and adolescents with excellent acceptance. The failure rate of 3.0 % of cases for pediatric MR imaging is comparable to that of a conventional low-field open MR scanner.

Analysis of the value of the perfusion parameter mean transit time (MTT) for the diagnosis of cerebral vasospasm after Subarachnoid Hemorrhage (SAH). Comparison with other perfusion parameters. An MTT threshold indicating the necessity of conventional angiography will be defined. ⋯ The analysis of the cortical perfusion parameter MTT is suitable for revealing clinically relevant global and regional vasospasm. A risk potential prediction is possible. An MTT of 3.2 s indicates a conventional angiography (DSA). This should be verified using a larger number of patients.
