METHOD FOR DIFFERENTIATED EVALUATION OF PYLOBULBAR STENOTIC STRUCTURE Russian patent published in 2004 - IPC

FIELD: medicine.

SUBSTANCE: one should carry out a continuous ultrasound testing of longitudinal cut in pylobulbar area. Additionally, ultrasound scanning should be performed of longitudinal cut in pylobulbar canal at the site of the highest narrowing of the lumen and deformation of walls' foliation. One should detect the structure of pylobulbar stenosis due to making an ultrasound amplitude histogram of desired area followed by registering the peak of ultrasound amplitude histogram and value of standard deviation. At peak value of ultrasound amplitude histogram being 15.4±2.3c.u. and standard deviation being 4.6±0.6c.u. one should detect normal structure of pylobulbar area. At peak value of 21.4±2.7c.u. and standard deviation being 7.8±0.7c.u. one should diagnose pylobulbar stenosis at prevailed inflammatory component. At peak value being 29.1±1.8c.u. and standard deviation being 5.8±0.6c.u. pylobulbar stenosis should be diagnosed at prevailed scar component.

EFFECT: higher efficiency of evaluation.
