Synopsis
Although a single-function phantom for either ADC or fat content is popular, it is crucial to develop a multiple-function phantom to simulate the real situation of human tissue in vivo. The aim of our study was to design a novel phantom containing different fat fractions and cellularity to evaluate the effect of fat content on ADC measurement in vivo as in human tissue environment. In conclusion, the influence of fat contents and glass beads density on ADC values was examined in our dual-function phantom, which can be helpful to improve the accuracy of ADC quantification in clinical practice.
