Renal MR angiography accurately diagnoses kidney vascular disease using advanced imaging and postprocessing. Future developments promise expanded functional assessments for comprehensive patient evaluation.

Area of Science:

  • Radiology
  • Medical Imaging
  • Cardiovascular Imaging

Background:

  • Renal MR angiography is highly accurate for diagnosing renal vascular disease.
  • Comprehensive examination requires assessing lumenal anatomy and hemodynamic significance of stenosis.

Purpose of the Study:

  • To outline the components of a comprehensive renal MR angiography examination.
  • To highlight the critical role of postprocessing in displaying vascular lesions.
  • To discuss the future potential of renal MR angiography.

Main Methods:

  • Utilizes three-dimensional gadolinium MR angiography for lumenal anatomy.
  • Incorporates functional techniques to assess hemodynamic significance of stenosis.
  • Employs postprocessing techniques like reformations and maximum intensity projections.

Main Results:

  • Postprocessing is crucial for optimal demonstration of vascular lesions through angiographic format.
  • Reviewing source images is essential to avoid missing pathologic findings.
  • Current techniques provide detailed anatomical and hemodynamic information.

Conclusions:

  • Renal MR angiography is well-suited for diagnosing renal vascular disease.
  • Advanced postprocessing enhances the display of vascular lesions.
  • Future MR angiography will likely integrate extensive functional information and novel techniques.
