| Popis: | On a 1.5-T MR unit conventional spin-echo (CSE) and fast spin-echo (FSE) images were obtained in 70 consecutive children ranging from 4 days to 13 years in age. They suffered from developmental retardation, neurodegenerative, ischemic or inflammatory diseases. In our prospective study artifacts, lesion conspicuity and general impression were compared between double-echo (proton density- and T2-weighted) CSE and single-echo (T2-weighted) FSE images. Phase artifacts from flowing blood were seen rarely on the FSE images, while motion artifacts appeared more frequently. Assessment of myelination in 43 children with unfinished myelination revealed no difference between FSE and CSE. The lesion conspicuity in 20 children with focal abnormalities compared favorably between FSE and CSE. There was no diagnostically relevant difference between FSE and CSE, although in FSE spin density images were missing. FSE sequences can be used in MR imaging of the pediatric brain without disadvantage and with a time reduction of 67-75%. |
