EARLY DIAGNOSTIC TECHNIQUE FOR SEGMENTAL AND SUB-SEGMENTAL; PULMONARY THROMBOEMBOLISM Russian patent published in 2014 - IPC A61B10/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, and can be used to diagnose pulmonary thromboembolism. Computed-tomography pulmonary angiography is performed. Complementary scanning is performed on the 30^th second from administering a contrast agent. That is followed by a post-processing preparation of the scanning findings. The preparation involves a visual assessment of the vessels and lung parenchyma taking into account the measured density of the lung parenchyma on the 30^th second after administering the contrast agent in the segment of the estimated hypoperfusion or aperfusion and in the intact region at the identical level in HU. The P1/P2 relation is calculated, wherein P1 is the density of the lung parenchyma after administering the contrast agent in the pulmonary artery in the segment of the estimated hypo- or aperfusion (HU), P2 is the density of the lung parenchyma in the intact region. If the P1/P2 relation is less than 0.2, pulmonary thromboembolism is diagnosed.

EFFECT: technique provides the higher accuracy, effectiveness and information value of diagnosing pulmonary thromboembolism by complementary scanning and assessment of the relation of the density of the lung parenchyma measured at complementary scanning and in the intact region.
