NLS-research methods in primary diagnostics of diseases of abdominal cavity organs become more and more available. Up to the present moment the NLS-images were in 2D which did not cover the dimensioned interrelation of structures under research. Significant information volume and accuracy increase is required to achieve fundamental improvement in NLS-image quality.

    That is why appearance of metatron 4025 hunter with 3D pictures feasibility became a new development stage of NLS-graphy. The multidimensional reconstruction mode is based on rendering of 3 mutually perpendicular imaging planes of the organ. The advantage of such method is getting of accurate topographic-anatomical interrelations between targeted structures which results in improvement of picture perception.

    Prognostic significance of 3D non-linear picture reconstruction in practical diagnostics is still being updated at the present moment. One of the possible upcoming trends of usage of the given procedure is an early detection of pathological changes in gastro-intestinal tract organs which requires emergency and scheduled surgical measures.

    NLS-diagnostics may become a procedure of choice for detection of concrements and dilatation degree of bile passages. When examining of patients with choledocholithiasis the classical picture of concrement is a hyperchromogenic structure (5-6 points according to Fleindler’s scale) of various forms. The accuracy of 3D NLS-diagnostics of choledocholithiasis is more than 95.0%.

    The minimal size of detected concrement in gall bladder is about 5 mm. for NLS-diagnostic systems of the first generation. Acquired image of concrement and gall bladder walls accuracy significantly improves when using 3D picture reconstruction mode in metatron 4025 hunter.
