Pre-Prepared, Low-Cost, Mass-Produced Phantom Regulated by the Food Standards Agency for Assessing Imaging Characteristics within MRI
Axford A., McGing J., Rua C., Symms M., Tyler D., Grist J.
A potential low-cost quantitative MR image assessment phantom was investigated by calculating relaxation times and the magnetization transfer ratio over multiple scans. An imaging protocol comprised of an inversion recovery sequence with varying inversion times, a spin echo with varying echo times, and an Enhanced Fast Gradient Echo 3D sequence with and without a magnetization transfer pulse, was developed and used to acquire images of the phantom, a block of store-bought jelly. The imaging data was used to calculate a T1 time of 109±1ms, a T2 time of 12.8±0.2ms, and an MTR value of 17.4±0.2%.
