A 32-channel Receive Array Coil for Pediatric Brain Imaging at 3T
نویسندگان
چکیده
Introduction: Pediatric MRI currently requires general anesthesia to preclude motion artifacts. With highly accelerated image encoding in conjunction motion navigators it may be possible to significantly reduce or even eliminate anesthesia. For research studies of brain development where anesthesia is not possible, improved motion robustness can significantly improve the success rate. Highly parallel array detection is thus critically needed for pediatric brain imaging. In this work we have designed and constructed a 32channel receive-only head coil to image 4 year olds. The sensitivity and image acceleration achievable with an optimized 32 channel pediatric brain array is compared with a commercially available 32-channel adult head coil and a 12-channel adult head coil.

96-Channel receive-only head coil for 3 Tesla: design optimization and evaluation.
The benefits and challenges of highly parallel array coils for head imaging were investigated through the development of a 3T receive-only phased-array head coil with 96 receive elements constructed on a close-fitting helmet-shaped former. We evaluated several designs for the coil elements and matching circuitry, with particular attention to sources of signal-to-noise ratio (SNR) loss, includin...

Size-optimized 32-channel receive array coils were developed for five age groups, neonates, 6 months old, 1 year old, 4 years old, and 7 years old, and evaluated for pediatric brain imaging. The array consisted of overlapping circular surface coils laid out on a close-fitting coil-former. The two-section coil former design was obtained from surface contours of aligned three-dimensional MRI scan...
متن کاملA 32 Channel receive-only 3T array optimized for brain and cervical spine imaging
Introduction: Simultaneous imaging of the brain and cervical spinal cord is integral to the study of pathologies involving both structures such as multiple sclerosis. Imaging the spinal cord is challenging due to its small size (~1cm diameter) and the presence of large B0 inhomogeneities that result in severe image distortions in diffusion-weighted and functional MRI acquisitions. These issues ...
متن کاملValidation of A Semi-flexible 64-channel Receive-only Phased Array For Pediatric Body MRI at 3T
Purpose: Pediatric MRI is often performed using receive coils designed for adult patients. The mismatch of the receive coils and the pediatric patients can cause degraded image quality [1]. In this work, a 64-channel receive-only phased array dedicated for pediatric body MRI is designed and constructed. This coil array incorporates the quarter-wavelength-balun technique, achieves ideal coil dec...

Parallel imaging has been demonstrated to reduce the encoding time of MR spectroscopic imaging (MRSI). Here we investigate up to 5-fold acceleration of 2D proton echo planar spectroscopic imaging (PEPSI) at 3T using generalized autocalibrating partial parallel acquisition (GRAPPA) with a 32-channel coil array, 1.5 cm(3) voxel size, TR/TE of 15/2000 ms, and 2.1 Hz spectral resolution.
