ABSTRACT
PURPOSE: To investigate the optimal positioning for low-birth-weight infants using a vacuum fixation device, considering the most suitable position for each manufacturer’s coil.
METHODS: Image data of low-birth-weight infants scanned at the institution were measured to assess their physical characteristics. Uniformity was evaluated by imaging a common phantom under identical imaging conditions using the head coils provided by GE Healthcare (Milwaukee, WI, USA), Siemens Healthineers (Erlangen, Germany), and Philips Healthcare (Best, the Netherlands).
RESULTS: The physical characteristics of low-birth-weight infants allowed them to fit entirely within all manufacturers’ coils. Uniformity varied depending on the coil type and the position within the coil: uniformity was highest in the deeper position for the GE 8-channel coil, in the central position for the Siemens 20-channel coil, in the deeper position for the Philips 32-channel coil, and in the central position for the Philips 20-channel coil.
CONCLUSION: When using a vacuum fixation device in low-birth-weight infants, optimal positioning was achieved by adjusting for the thickness of the fixation device and placing the infant at the position within the coil where imaging uniformity was highest.
