Abstract

PurposeHeating of gradient coils and passive shim components is a common cause of instability in the B0 field, especially when gradient intensive sequences are used. The aim of the study was to set a benchmark for typical drift encountered during MR spectroscopy (MRS) to assess the need for real-time field-frequency locking on MRI scanners by comparing field drift data from a large number of sites.MethodA standardized protocol was developed for 80 participating sites using 99 3T MR scanners from 3 major vendors. Phantom water signals were acquired before and after an EPI sequence. The protocol consisted of: minimal preparatory imaging; a short pre-fMRI PRESS; a ten-minute fMRI acquisition; and a long post-fMRI PRESS acquisition. Both pre- and post-fMRI PRESS were non-water suppressed. Real-time frequency stabilization/adjustment was switched off when appropriate. Sixty scanners repeated the protocol for a second dataset. In addition, a three-hour post-fMRI MRS acquisition was performed at one site to observe change of gradient temperature and drift rate. Spectral analysis was performed using MATLAB. Frequency drift in pre-fMRI PRESS data were compared with the first 5:20 minutes and the full 30:00 minutes of data after fMRI. Median (interquartile range) drifts were measured and showed in violin plot. Paired t-tests were performed to compare frequency drift pre- and post-fMRI. A simulated in vivo spectrum was generated using FID-A to visualize the effect of the observed frequency drifts. The simulated spectrum was convolved with the frequency trace for the most extreme cases. Impacts of frequency drifts on NAA and GABA were also simulated as a function of linear drift. Data from the repeated protocol were compared with the corresponding first dataset using Pearson's and intraclass correlation coefficients (ICC).ResultsOf the data collected from 99 scanners, 4 were excluded due to various reasons. Thus, data from 95 scanners were ultimately analyzed. For the first 5:20 min (64 transients), median (interquartile range) drift was 0.44 (1.29) Hz before fMRI and 0.83 (1.29) Hz after. This increased to 3.15 (4.02) Hz for the full 30 min (360 transients) run. Average drift rates were 0.29 Hz/min before fMRI and 0.43 Hz/min after. Paired t-tests indicated that drift increased after fMRI, as expected (p < 0.05). Simulated spectra convolved with the frequency drift showed that the intensity of the NAA singlet was reduced by up to 26%, 44 % and 18% for GE, Philips and Siemens scanners after fMRI, respectively. ICCs indicated good agreement between datasets acquired on separate days. The single site long acquisition showed drift rate was reduced to 0.03 Hz/min approximately three hours after fMRI.DiscussionThis study analyzed frequency drift data from 95 3T MRI scanners. Median levels of drift were relatively low (5-min average under 1 Hz), but the most extreme cases suffered from higher levels of drift. The extent of drift varied across scanners which both linear and nonlinear drifts were observed.

Abstract

Brain maturation is an important factor in cognitive, emotional, behavioural and motor development during childhood and adolescence. This study uses multi-modal magnetic resonance imaging (MRI) techniques to assess neural representations of devel opment in both healthy and abnormally developing populations. A novel face emotion stimulus set, designed to assess distinct dimensions of facial emotion, particularly to assess the e ect of averted faces, is introduced in a pilot functional MRI study of an adult cohort. Results from this pilot study show that interactions between face direction and emotion can infuence which brain areas are recruited for emo- tion processing, suggesting that the neural correlates of judging facial emotion content are modulated by face direction. Facial emotion perception was assessed as a neural task to investigate dimensions of emotion processing, and emotion processing development, in a group of children and adolescents. A number of correlations were found between dimensions of the task and developmental measures such as age, pubertal development and intelligence. In particular, intelligence was shown to be positively associated with the increasing utilization of regions associated with cognitive control, such as the prefrontal cortex. A voxel-based morphometry (VBM) study explored potential structural correlates of adolescent development. Age was found to correlate with changes in local brain regions, however pubertal development was shown to be a more accurate measure of those changes. A diusion tensor imaging assessment of white matter using fractional anisotropy has demonstrated important developmental di erences in white matter be- tween males and females over childhood and adolescence. Findings also suggest diff erent relationships between intelligence and white matter for males and females. Developmental Coordination Disorder, a common childhood disorder characterised by deficits in learning and automating motor skills, was assessed as an example of ab normal brain development. VBM was used to show that kinematic metrics of a simple visuomotor task correlated with regional grey matter volumes.

27. Landscape in Literature.

Author

Association of American Geographers, Washington, DC., Salter, Christopher L., and Lloyd, William J.

Abstract

One of a series of Resource Papers for College Geography, this thematic study guide focuses on literary setting and the personal space of fictional characters as an approach to comparative literary study, and concurrently uses fictional treatments of landscape and place as a means to encourage greater sensitivity to geographical and architectural space. The suggested methodology relates to the concept of landscape signatures, the specific imprints people or peoples have made upon the earth in their use of geographical space. The authors recommend having students reread known works with attention to the way the author creates and employs settings, choose a landscape and search for distinctive and contrasting views of that landscape, and consider how landscapes are utilized in the work of a single author. The guide discusses literature and geography in general terms; approaches to reading for setting; landscapes of settlement, agriculture, livelihood, sacred spaces, and transportation; the shaping of personal space in home and garden; and entertainment landscapes. Bibliographies of fictional and reference works are included. (DS)
