The Clinical Study On Application Value Of Three-dimensional Ultrasound Imaging Of Static Structures With Free-hand And Volume Transducer

Objective: To evaluate clinical application of three-dimensional (3D) ultrasound imaging of static sructures with free-hand and volume transducer.Methods: part 1: 27 patients with deripheral vascular atherosclerosis,11 patients with hepatic tumor, 24 patients with gallbladder disease and etc were examined by two-dimensional(2D) ultrasound and free-hand 3D ultrasound respectively. The 2D and 3D ultrasonic imaging gained was contrasted and analyzed by two practiced ultrasonic doctors on five aspects including distinctness, stereo feeling, contrast ratio, relation to surround and completeness; Part 2: 12 fetuses, 3 carotid arteries, 5 uteruses and 3 kidneys were examined by 2D ultrasound and 3D reconstructed system and real-time 3D ultrasound respectively. And the 2D and 3D ultrasonic imaging gained were contrasted and analyzed too.Results: part 1 .-Compared between 2D and 3D ultrasonic imaging of 94 study objects , the degrees of satisfaction to free-hand 3D ultrasonic imaging was significantly higher than that of 2D(p< 0. 05), and it can provided more clinical information. Part 2:Compared among 2D, 3D reconstructed system and real-time 3D ultrasonic imaging of 23 study objects, the 3D ultrasonic imaging was more excellent thanthat of 2D.Conclusions: Three-dimensional ultrasound imaging of static structures with Free-hand and volume transducer which were two advanced types of 3D ultrasonic imaging, could provide comprehensible ultrasonic imaging. And it has important clinical values and application potentialities for diagnosing diseases in cardiovascular abdomen and gynemetrics,...
