Abstract:

MRI scan frequently exceeds half an hour and young children have difficulty keeping still for such long periods. Images are non-diagnostic and marred by motion artifact when children or adults move during the scan. Vendors have created ultrafast sequences which propose to be able to scan the brain in a very short imaging time of 5 minutes compared to our standard MRI brain protocol which has an imaging time of 14 mins. In this prospective study, children scheduled for MRI brain underwent both the ultrafast MRI as well as standard MRI protocol. The presence of artifacts on each set of scans for the children were compared across the T1, T2, FLAIR, DWI and SWI sequences in both protocols and statistical significant differences were calculated using chi square test. Out of 30 children, who had MRI brain scan, 13 (43%) of the ultrafast scans were non-diagnostic due to artefact. For the rest of the 17 scans, the diagnoses made on ultrafast scans were similar to the diagnosis made on the standard MRI scans. Artifacts seen on the ultrafast T2 and FLAIR images were statistically significantly more than those present on standard MRI. Time taken to carry out 30 standard MRI brains is 30Ã?14 mins=420 minutes. Time to carry out 30 ultrafast MRI brains is 30Ã?5=150 minutes. Even after factoring time required to carry out supplementary standard brain MRI to supplement the 43% of ultrafast imaging with non-diagnostic MRI=150 minutes + (13Ã?14 minutes)=332 minutes, ultrafast MRI provides time saving compared to standard protocol for all (which is 420 minutes). Ultrafast MRI is effective and saves time even with some scans having artifacts and requiring supplementation with standard MRI brain.
