METHOD FOR DETERMINING INTRAPULMONARY OR EXTRAPULMONARY LOCALIZATION OF PARIETAL THORACIC NEOPLASM Russian patent published in 2000 - IPC

FIELD: medicine. SUBSTANCE: method involves applying ultrasonic scanning of the chest with scanner operating in real time gray scale mode after taking X-ray pictures of the chest. Transducers are used at frequency of 3.5-5 MHz, 0-7.5 MHz. Scanning is carried out in vertical and horizontal positions of a patient through intercostal space along the reference anatomic topography lines. Parietal hyperechogenous line of pneumatic lung surface is studied for its position, integrity and discreteness. Interruptions of parietal hyperechogenous line being observed at the level of neoplasm, interruption of the parietal hyperechogenous line being observed along the lateral edge of the neoplasm in scanning depth between the parietal hyperechogenous line and hyperechogenous line behind the internal boundary of the neoplasm, acute parietal angle being found between the parietal hyperechogenous line and lateral surface of the neoplasm, intrathoracic localization of the parietal neoplasm is to be diagnosed. Extrapulmonary localization of the parietal neoplasm is considered to be the case, when deviation of the parietal hyperechogenous line at the level of the neoplasm is directed inside from its natural position, no interruption in scanning depth between the parietal hyperechogenous line and hyperechogenous line behind the internal boundary of the neoplasm along the lateral edge of the neoplasm and obtuse or right angle between the parietal hyperechogenous line and lateral surface of the neoplasm is detected. EFFECT: enhanced accuracy of diagnosis. 4 dwg
