The Production and Evaluation of the Tissue-equivalent Phantom for the Magnetic Resonance Imaging
Abstract
- PURPOSE
For the production and evaluation of the tissue-equivalent phantom.
MATERIALS AND METHODS
We used agarous gel and oil as a basic component of the mixture and added Tween 80 for the stabilization of phantoms. We did the test for homogeneity and measured T1 and T2 relexation times of each phantom tube.
RESULTS
T1 relaxation time ranged from 642 to 2781 msec and T2 relaxation times from 42 to 157 msec. Each phantom was significantly different in T1 relaxation time and T2 relaxation time (p < .0001).
CONCLUSION
Tissue equivalent phantom may provide good information on the optimal sequence before MR imaging of patients and may be valuable if it is used with the patients' MR imaging.
