FIG 4. 56-year-old man after resection of a high-grade sarcoma of the masticator space and placement of a pectoralis rotational flap. Imaging studies were obtained 2 months postoperatively. This case illustrates nonenhancement of the muscular graft component.

A, Axial T1-weighted (450/9/2) image shows a medially situated fatty graft component (black dots) and a laterally situated muscular graft component with obvious striations (arrowheads).

B, Contrast-enhanced, fat-suppressed T1-weighted (583/9/2) image shows signal suppression of the fatty component and no enhancement of the muscular graft component.
