DIFFERENTIAL DIAGNOSIS METHOD FOR DIAGNOSING NODULAR FORMATIONS IN THYROID GLAND Russian patent published in 2006 - IPC A61B10/00 G01N33/48 

FIELD: medicine.

SUBSTANCE: method involves taking thin needle suction biopsy from a nodular formation in thyroid gland under ultrasonic scanning control and carrying out cytological study of puncture material. Liquid portion of the puncture material is additionally studied by applying wedge-like dehydration method. To do it, the puncture material is first centrifuged during 10-15 min at 1500-3000 rpm and then supernatant drop is dried on object-plate during 18-24 h at room temperature with minimum air circulation movement being permitted. The so produced facies structure is studied with microscope. Arc-shaped cracks being found in peripheral zone of the facies, benign node nature is considered to be the case. Broken line pattern cracks being found in peripheral zone of the facies, malignant node nature is considered to be the case.

EFFECT: high accuracy and sensitivity of differential diagnosis.
