A recent study conducted in Utrecht, Netherlands, focused on improving advanced intraoperative MRI methods during pediatric neurosurgery. The researchers aimed to develop a protocol for intraoperative MRI with increased sensitivity for arterial spin labeling (ASL) and diffusion MRI (dMRI), optimized for patient positioning commonly used in pediatric neurosurgery. The study found that ASL cerebral blood flow (CBF) did not differ between the surgical prone and supine positions, and the use of four RF coils instead of two resulted in higher signal-to-noise ratio (SNR) and reduced susceptibility artifacts. The research concluded that ASL and dMRI acquisition with two RF coils can be performed adequately for clinical use, but the use of four RF coils improves image quality and sensitivity to artifacts.
