  Purpose

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

Condition Intervention
Healthy Device: Pneumatic Driver

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Renal MR Elastography: Normal Findings and Variability of Stiffness Measurements

Further study details as provided by Hospices Civils de Lyon:

Primary Outcome Measures:
  • Normal kidney stiffness (measured from MRE data) [ Time Frame: 2 months ]
  • Variability of stiffness measurement (on repeat examination) [ Time Frame: 2 months ]

Secondary Outcome Measures:
  • Tolerance of the procedure [ Time Frame: 2 months ]
  • Percentage of partial and total technical failures [ Time Frame: 2 months ]
  • Quality criteria of stiffness measurements (area of the ROIs used for measurement, mean induced displacement measured in the ROIs) [ Time Frame: 2 months ]

Enrollment: 10
Study Start Date: March 2009
Study Completion Date: July 2009
Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Pneumatic Driver

    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.
