The Development Of NLS-diagnostics With Metatron 4025 Hunter For Major Duodenal Papilla Tumors
Technological innovations of the recent years in equipment for non-linear diagnostics and software resulted in cardinal extension of NLS-research application area and improvement of images quality. One of the promising directions for the development of NLS-diagnostics with metatron 4025 hunter is a mode of multidimensional virtual reconstruction of an NLS-image, allowing to visualize crosscuts and anatomical reconstruction of a researched area, which remain invisible during application of two-dimensional scanning only. This method offers the possibility of data manipulating, using rotation and zooming, rendering true anatomy of organs in a direct projection. Three-dimensional NLS-scanning has a certain technical and practical advantages in visualization of anatomical and pathological structures in comparison with two-dimensional visualization. The method allows to make a crosscuts of acquired image, for example frontal ones, or to isolate separate areas in Fast Vision mode. It makes possible to see an internal structure of a parenchymatous organ, and if there are areas of affection inside the investigated region, an operator can isolate and zoom in areas of a parenchyma and thus see intratissual growths – in NLS-ultramicroscanning mode. Spectral-entropic analysis (SEA) mode allows to define morphological character of a researched area by comparison of spectral similarity with etalon processes.
According to T. Guseva et al., three-dimensional NLS is better in investigation of anatomical motion of hepatic vessels and biliary ducts, than standard two-dimensional NLS-investigation.
A. Schvack in his work evaluates practicability of three-dimensional NLS-scanning application in work with patients suffering from obstructive diseases of bile-excretory system. After comparison of three-dimensional NLS-scanning with endoscopic retrograde cholangiopancreatography it was noted that three-dimensional NLS-scanning has almost the same efficiency and informativity in evaluation of biliary system pathology as endoscopic retrograde cholangiopancreatography.
The Application Of Metatron System - Metatron 4025 Hunter
50 patients with various bacterial infections were examined in order to test possibilities of hardware-software system "Metatron"; patients were inscribed in studied groups after their diagnosis was defined using laboratory data, including bacteriologic and histological research, ultrasound research results, diagnostic laparoscopy and intraoperative research. Carriers of various bacterial infections and great variety of microorganisms were revealed by NLS diagnostics. At the same time accuracy of this method is 86.2%, specificity – 86%, sensitivity – 92.4%. Results are positive in 88.2% of cases, 11.8% are negative. Time for one patient check up is from 30 minutes to 1 hour. Using this method Helicobacter pilori revealed in 20% of cases, when immune-enzyme analysis reveals up to 100% of cases. This method can be regarded as accurate at revealing of enteric infections, golden staphylococcus, streptococcus, syphilis when accuracy rate is 100%.
