title: [Boundary low intensity band between fat and organ on opposed phase gradient echo image].
abstract: Phantom study was done to consider the mechanism of boundary low intensity band between fat and organ on opposed phase gradient echo image. Phantom 1 consists of 10 syringes that contain gelatinized olive oil and water emulsion of various concentrations. Phantom 2 is a small water tank that contains olive oil and water. Images of in phase and opposed phase gradient echo were obtained with 1.0 T unit. Phantom 1 study proved signal intensity of oil and water emulsion was magnitude of oil signal-water signal. Phantom 2 study suggested the most domestic cause of boundary low intensity band was signal cancelling of coexisting fat and water in the boundary.
