J Appl Clin Med Phys. 2021 Nov 02; doi: 10.1002/acm2.13469. Epub 2021 Nov 02.

To investigate the spatial accuracy of delineating prostatic calcifications by quantitative susceptibility mapping (QSM) in comparison with computed tomography (CT), we conducted phantom and human studies. Five differently-sized spherical hydroxyapatites mimicking prostatic calcification (pseudo-calcification) were arranged in the order...
