[en] The authors developed a three-dimensional display technique for blood vessels related to soft tissues, using MR images generated by the three-dimensional Fourier transform method or multisection method. An application of this study for neurosurgery provided satisfactory results. In this paper they describe this display technique and its clinical practice, including procedures (1) to enhance blood vessels by nonlinear filter capable of detecting three-dimensional line patterns without losing the form of soft tissues, (2) to generate three-dimensional images by the numerical projection, and (3) to present three-dimensional display utilizing the dynamic or binocular parallex (animation display or stereoscopic display). This technique facilitates the recognition of the three-dimensional structure of blood vessels related to soft tissues
