The muscles are sharply outlined in black. 

Case Discussion

Black boundary artifact or india ink artifact is an artificially created black line located at fat-water interfaces such as those between muscle and fat. This results in a sharp delineation of the muscle-fat boundary that is sometimes visually appealing but not an anatomical structure.
