Magnetic Resonance (MR) renography offers a noninvasive method to assess kidney function, improving diagnosis and reducing costs. This review covers MR renography techniques, clinical uses, and future challenges in kidney imaging.

Area of Science:

  • Radiology
  • Nephrology
  • Medical Imaging

Background:

  • Magnetic Resonance (MR) imaging provides a noninvasive assessment of renal status.
  • It offers diagnostic improvements and cost reductions in kidney evaluation.
  • MR renography is a key technique in this field.

Purpose of the Study:

  • To review various MR renography techniques.
  • To discuss methods for quantifying renal perfusion and glomerular filtration rate (GFR).
  • To explore clinical applications of MR renography.

Main Methods:

  • Review of existing literature on MR renography.
  • Description of techniques for assessing renal perfusion.
  • Explanation of methods for GFR quantification.
