“…While a higher field strength is expected to improve image quality, the theoretical doubling of the signal-to-noise ratio was no higher than 25%. 15 In agreement with our results, Debatin and Patak 16 conclude that 3.0-T imaging is subject to significantly more artefacts when using specific sequences such as trueFISP.…”

Objectives: To compare the image quality of MRI scans produced with 1.5-and 3.0-T devices during functional test condition. Methods: 65 MRI scans obtained with 1.5-(n 5 43) or 3.0-T (n 5 22) true fast imaging with steady-state precession (trueFISP) sequences from patients with a history of a cleft palate were evaluated. Two experts assessed the MRI scans, independently of each other, and blinded to the MRI technique used. Subjective ratings were entered on a five-point Likert scale. The median planes of three anatomical structures (velum, tongue and pharyngeal wall) were assessed in three functional states (at rest, during phonation of sustained "e" and during articulation of "kkk"). In addition, MRI scans taken during velopharyngeal closure were evaluated. Results: Under blinded conditions, both observers (radiologist and orthodontist) independently rated the quality of 1.5-T scans higher than that of 3.0 T. Statistical analysis of pooled data showed that the differences were highly significant (p , 0.009) in 4 out of 10 test conditions. The greatest differences in favour of 1.5 T were observed for MRI scans of the velum. Conclusions: 1.5 T used with trueFISP may be preferable over 3.0-T trueFISP for the evaluation of the velopharyngeal structures in the clinical routine.

“…Other limitations include our use of a 1.5 T scanner and a relatively short resting-state scanning time. Although a 1.5 T scanner is adequate for fMRI 37 and for visualizing amygdala subregions (e.g., see the study by Vogel and colleagues 38 ), this study warrants replication at higher resolution and with longer scan durations. Moreover, although the study therapists were highly experienced and followed a treatment manual, we did not evaluate fidelity to the manual or assess treatment compliance among patients.…”

“…However our review highlights a lack of direct comparisons of CVR between 1.5 and 3 T. 24 Therefore, more data are required to determine the true differences in BOLD signal and artefacts due to field strength.…”

Cerebral small vessel disease (SVD) pathophysiology is poorly understood. Cerebrovascular reactivity (CVR) impairment may play a role, but evidence to date is mainly indirect. Magnetic resonance imaging (MRI) allows investigation of CVR directly in the tissues affected by SVD. We systematically reviewed the use of MRI to measure CVR in subjects with SVD. Five studies (total n ¼ 155 SVD subjects, 84 controls) provided relevant data. The studies included different types of patients. Each study used blood oxygen level dependent (BOLD) MRI to assess CVR but a different vasoactive stimulus and method of calculating CVR. CVR decreased with increasing white matter hyperintensities in two studies (n ¼ 17, 11%) and in the presence of microbleeds in another. Three studies (n ¼ 138, 89%) found no association of CVR with white matter hyperintensities. No studies provided tissue-specific CVR values. CVR decreased with age in three studies, and with female gender and increasing diastolic blood pressure in one study. Safety and tolerability data were limited. Larger studies using CVR appear to be feasible and are needed, preferably with more standardized methods, to determine if specific clinical or radiological features of SVD are more or less associated with impaired CVR.
