Metatron hunter-ultramocroscanning mode

Altogether 788 space-occupying growths were detected in 402 (73.4%) of 548 examined patients. In 21 (2.7%) cases colorectal cancer was diagnosed, the remaining 767 growths were verified as polyps (see Table 1). In 74 cases they were identified as flat polyps (its root is twice larger than its height) with visualization in a shape of half-oval hyperchromogenic node in a colonic wall (5 points at Fleindler’s scale). The best visualization was in Metatron hunter-ultramocroscanning mode. Minimal diameter of a revealed by Metatron hunter growth was 2 mm. To increase a sensitivity in revealing of small polyps we had to compare image of a colon in metatron hunter-ultramocroscanning mode with spectral-entropic analysis. Multiple polyps were revealed in 6 (1.5%) of 402 patients. Polyps were properly visualized both on axial crosscuts and in Metatron hunter-ultramocroscanning mode with spectral-entropic analysis as a hypechromogenic structure (5-6 points at Fleindler’s scale) at edges and isochromogenic (2-4 points) in a center of a polyp. Application of endoscopic colonoscopy confirmed in all patients presence of polypous growths, detected by spectral-entropic analysis, size of which was above 8 mm. Morphologically verified by spectral-entropic analysis polyps were of various histological structure; results of polyps histological study are represented in the Table 1.

Bioplasm machine-research of urinary bladder

Full-scale Bioplasm machine-research of 365 patients (aged 26 – 83) with malignant tumoral affection of urinary bladder was performed in the Institute named after Gertsen P.A. 317 patients (86.8%) suffered from bladder cancer, 4 patients (1.1%) had sarcoma, 6 patients (1.6%) suffered from tumor deposits of another primary site, 2 patients (0.5%) had malignant non-Hodgkins lymphoma with bladder affection, 36 patients (9.9%) had tumor ingrowths into bladder wall from the adjacent organs. Male patients consisted the majority – 273 patients (74.8%) and 92 female patients (25.2%). All patients were examined using Bioplasm machine-research of urinary bladder. In all cases the microscanning of urinary bladder wall with spectral-entropy analysis of tissue structures was performed to provide differential diagnostics of various cancer types. All patients were operated on not later than 2 weeks after performance of NLS-research, the data of morphological research were compared with the result...

Three-dimensional Metatron hunter-graphy was carried with Metatron-4025 (IPP, Russia) system

http://www.metapathia-hunter.com At the first stage all patients were subjected to routine ultrasound examination of hepatobiliary system organs. Further on, in order to specify a nosological for of a disease, we used method of three-dimensional virtual Metatron hunter-reconstruction of an image and other hardware and laboratory researches (in accordance to medical and financial standards for this nosological type of a disease). Ultrasound examination was carried out with Acuson Sequoia 512 (Siemens, Germany) device, with multifrequency curvilinear transducer (2.5 – 6 MHz). Three-dimensional Metatron hunter-graphy was carried with Metatron-4025 (IPP, Russia) system with 4.9 GHz frequency generator and “Metapathia GR Clinical” software allowing to carry out three-dimensional virtual rendering of an object. Three-dimensional reconstruction was possible because of integrated into Metatron system specialized computer and mathematical program for Metatron hunter-information processi...

Possibilities of non-linear method in diagnostics of adrenals tumors

图片
http://www.metapathia-hunter.com Adrenals tumors are registered comparatively rarely, but it is know that they are most frequently hormone-active and even at small sizes lead to various endocrine disorders. However sometimes in clinical practice there are adrenals tumors without clinical symptoms and vague complaints of patients. References and our own experience show that period from appearance of the first symptoms till diagnosing varies from 6 months to 2 years.Early diagnostics of adrenals tumor has become an important clinical issue, which may be solved by application of non-linear diagnostics (NLS) along with CT, MRI and angiography. Today NLS-graphy is one of the most informative and prospective methods of diagnostics. Thanks to easiness of application, high informativity and safety NLS-graphy becoming a method of choice even at the first stage of hardware methods of diagnostics. NLS method of study allowed to increase significantly percentage of early and accu...
