Abstract:
The purpose of this study was to construct and evaluate a phantom for measurement of magnetic resonance (MR) imaging sections with thicknesses of 0.3-0.6 mm. The phantom consisted of 304 0.1-mm-thick disks, each of which had a single notch filled with a diluted solution of gadopentetate dimeglumine. Qualitative and quantitative evaluations of T1-weighted images with section thicknesses of 0.3-0.6 mm were performed. A computer simulation was performed to evaluate the influence of different examination angles. At quantitative evaluation, the difference between nominal and measured section thicknesses ranged from 11% (nominal section thickness, 0.6 mm) to 18% (nominal section thickness, 0.4 mm). Computer simulations revealed that the phantom's positioning along the z-axis had a negligible influence at quantitative evaluation.
