Common indications for CT and MRI of the kidneys

What are the common indications for CT and MRI of the kidneys?

The most common clinical indications include:

  • • Characterization of indeterminate renal lesions detected on prior cross-sectional imaging. This is done most frequently to distinguish a benign lesion such as a renal cyst from a malignant primary or metastatic neoplasm.
  • • Surveillance of patients with genetic syndromes who are at increased risk for renal cell carcinoma (RCC).
  • • Staging and response assessment of patients with renal malignancies.
  • • Pretreatment and post-treatment evaluation of patients undergoing renal transplantation, as well as pretreatment evaluation of live renal donors.
  • • Evaluation of patients with abdominal symptoms or signs (e.g., flank pain, hematuria) that are suspected to be secondary to renal disease.
  • • Assessment for traumatic injury to the kidneys (mainly using contrast-enhanced CT).
  • • Providing guidance for percutaneous biopsy or intervention for renal disease.
