| الملخص: | The aim of this study is to explore the feasibility, suitability, and compatibility of
polyvinyl acetate slime as tissue mimicking phantom for magnetic resonance
spectroscopy (MRS) studies. Phantoms are made with gelling agents and some without
by measuring the ingredient and mixing them. In this study, there are seven types of
phantoms with different ingredient. Four of them are PVA slime phantoms which were
fabricated with different additives that are water, oil, milk and salt. While the other three
consist of water, oil and milk only which were regarded as control. MRS imaging was
performed using Philips Achieva 3 Tesla MRI system available at Department of
Radiology, HUSM. All phantoms were characterized base on their MR spectra and
chemical shift. The MR spectra and chemical shift of the phantoms were also compared
with those of normal and pathological tissue. The result from this study show that the
chemical shift and especially the metabolite ratio data are much likely equivalent to
human tissue. It can be concluded that PVA slime phantom can be use as tissue mimicking
phantom for MRS as the characteristics of the phantom is suitable to use in MRS. |
