Abstract
For enhancement of visualization and 3D image reconstruction of intracranial pathological forms, it is suggested to use MR images obtained with simultaneous water and fat signal suppression. In this case one can more distinctly reveal pathological forms which are hidden ordinarily under powerful signals of fat tissue (orbits and hypodermic fat) and free water (brain ventricles). To realize simultaneous suppression of strong water and fat signals, we use modified sequence "inversion-recovery" supplemented by second inversion pulse. The signal/noise ratio degrades insignificantly in comparison with common "inversion-recovery" technique. Yet due to suppression of intensive background signals the dynamic range of the receiver extends and its responsiveness to weak signals improves. Herewith the graphical data processing and construction of 3D images are significantly simplified as tissue contrast picture is maximally refined. The method is illustrated by 3D images in the cases of subdural haematomas and intracranial tumors. Drawing of 3D images for pathological forms was carried out by the standard software of MR scanner TOMIKON S50 (Bruker) which was used in MRI investigations.
