Objectives: After studying the article entitled “Comparison of Diagnostic Medical Sonography, Computed Tomography, Magnetic Resonance Imaging, and Contrast Enhanced Ultrasound in the Investigation of Renal Lesions,” you will be able to:
Identify the strengths, limitations, and benefits of differing modalities for use in the kidneys
Describe the incidence of renal pathologies
Discuss the system used to classify renal lesions
Which imaging modality is recommended by the American College of Radiology Appropriateness Criteria for a patient with renal insufficiency or contraindications for intravenous contrast? Diagnostic medical sonography (DMS) Magnetic resonance imaging (MRI) Contrast-enhanced ultrasound (CEUS) Computed tomography (CT)
According to the Bosniak classification system, which type of follow-up is needed for a type IIF lesion? None Repeat imaging Surgical intervention Varies by institution
Which is the most common benign renal abnormality seen across all imaging modalities? Lipoma Renal cell carcinoma Polycystic kidney disease Simple cyst
Which is a known weakness of using CT to characterize renal masses? Increased sensitivity and detail Sufficient to characterize subtle differences Exposure to ionizing radiation Fast acquisition time
Which is a known weakness of CEUS? Inability to differentiate between some masses More cost-effective than MRI Nonionizing radiation technique Low incidence of adverse contrast reactions
