简要总结
MR Elastography is a new technique aimed at non-invasively measuring the stiffness of tissues. It has recently given interesting results in the assessment of liver fibrosis.
The objectives of the current study are:
- to develop an imaging protocol for MR Elastography of the kidneys;
- To calculate the stiffness of normal kidneys;
- To evaluate the variability of the measurements of kidney stiffness by repeating the procedure twice on the same volunteers.
