The Role of Dynamic Contrast-Enhanced MRI in a Child with Sport-Induced Avascular Necrosis of the Scaphoid: A Case Report and Literature Review

Figure 2

To assess the vascularity with dynamic contrast-enhanced MRI, a region of interest was placed on the proximal and distal scaphoid poles and time-signal intensity curves were recorded. The dynamic contrast-enhanced MRI showed fair perfusion of the proximal pole with account of measuring associated fibroblasts in the cystic alteration in the distal pole. The time-signal intensity curve on the proximal pole (yellow curve) was lower than the distal pole (red curve) with a maximum enhancement of 50%.
