DIAGNOSTICS OF LAMBLIASIS AFFECTION OF HEPATOPANCREATODUADENAL ZONE Russian patent published in 1994 - IPC

FIELD: medicine. SUBSTANCE: diagnostics is exercised by using ultrasonic examination of a patient in twelve hours after his/her last meal. The examination is carried out by real-time devices with 3.5 Mcs sensor. Patient lies on his/her back or left side horizontally in a phase of a deep breath. Echo location of patient's liver and pancreas in crossing and slanting directions is carried out changing angle of the sensor by one degree. Turning "brightness of image" knob they exercise observation in 6-8 points regime. Then brightness is decreased to its minimum values up to the liver parechima and pancreas tissue image disappears. Depth of mechanical pressure of the sensor scanning surface on patient's skin surface in the area of examined organs is not more than 0.5 cm. They estimate the whole complex of echographic pathological features, that become apparent as small oval up to 0,2 cm diameter formations located mainly in the area of liver periphery, and visualization of Wirsung's duct with thickened and hardened walls, appeared in the form of amplification of echo signal against a background of brightness decreasing up to patient's liver parechima and pancreas tissue image disappearance on a monitor screen. EFFECT: it increases accuracy of the diagnostics.
