Recent advances in imaging techniques of renal masses

Figure 3 Dual-energy computed tomography images. A: Contrast-enhanced axial dual-energy computed tomography image showing contour bulge from the lateral cortex of the interpolar region of the left kidney, enhanced similar to background parenchyma; B: Iodine overlay image confirming the absence of any differential iodine distribution, suggesting the lesion to be a dromedary hump.
