A new stage of development in echinococcosis surgery is associated with the development of new, more informative diagnostic tools: the Metatron 4025 Hunter NLS study first computed tomography (CT), magnetic resonance tomography (MRT) and spiral computed tomography ( HCT).

According to several authors, the informative value of the NLS method in the case of hepatic echinococcosis depends on the stage of development of the parasite (live or dead) and is on average at least 90-97%. Diagnostic difficulties may arise in patients with large cysts (with live parasites) as well as in patients with dead echinococcosis. CT and MRI diagnostic error frequency in cases of liver formation less than 1 cm. up to 52%.

Diagnostic imaging methods are adjunctive and can often show indirect signs of complicated hepatic echinococcosis. The detection rate of imaging signs such as high position of the diaphragmatic cup, deformation, and limited movement only appeared in the case of a large subdiaphragmatic cyst with a large location and volume, and the detection rate ranged from 12.5% to 23.4%.

The use of NLS (compared to CT, providing panoramic images and higher sensitivity in some locations, accurate differential and regional diagnosis) is the next step in the improvement of the diagnosis of complex hepatic echinococcosis. NLS provides more efficient differentiation of "pseudophyllous" echinococcosis forms from tumors by spectral entropy analysis (SEA). The overall accuracy of NLS in diagnosing echinococcosis exceeds 95%.

The NLS diagnostic method using biomass NLS has the following key advantages: efficient estimation of cyst size, their number and location in the liver, their interrelationship with blood vessels and bile ducts, estimation of parasite developmental stage, and detection of echinococcosis on other organs. Influence. This information is crucial in determining the surgical approach, planning the type and extent of surgery, and suggesting possible intraoperative complications.

From the above it can be seen that the introduction of Metatron 4025 Hunter with SEA into clinical practice has significantly improved the diagnosis of complicated echinococcosis, especially in early forms, which often allows for radical, but also economical intervention. However, existing instrumental diagnostic methods do not provide 100% accurate results. In 2-9% of cases, the nature of the hepatic cyst formation could not be determined using hardware study methods.
