Brief Summary

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:

  1. 1.to develop an imaging protocol for MR Elastography of the kidneys;
  2. 2.To calculate the stiffness of normal kidneys;
  3. 3.To evaluate the variability of the measurements of kidney stiffness by repeating the procedure twice on the same volunteers.

Outcome Measures

Primary Outcomes (2)

  • Normal kidney stiffness (measured from MRE data)

    2 months

  • Variability of stiffness measurement (on repeat examination)

    2 months

Secondary Outcomes (3)

  • Tolerance of the procedure

    2 months

  • Percentage of partial and total technical failures

    2 months

  • Quality criteria of stiffness measurements (area of the ROIs used for measurement, mean induced displacement measured in the ROIs)

    2 months

Interventions

Ten healthy volunteers will undergo MR Elastography using a pneumatic driver connected to a commercially available speaker and the stiffness of the left kidney will be measured. The examination will be repeated on the same volunteers at least one month later and the same stiffness measurements will be performed.
