13 Motion in Cardiovascular Radiography
The minute has given way to the second as an expression of radiographic exposure duration. It is predicted that the millisecond will be the term of the future. Arterial blood velocity exceeds 50 cm. per second. In cardiovascular radiography, especially angiocardiography, maximum detail cannot be achieved unless the x-ray exposure is short enough to "stop" rapid movement. Practical experience in...
متن کاملBilateral Arm-Abduction Shoulder Radiography to Determine the Involvement of the Scapulothoracic Motion in Frozen Shoulder
Background: We hypothesize that there is no difference in the motion of the scapula with respect to the thoracic wall (scapulothoracic interface) between the affected versus non-affected shoulder on 0° and 90° standard arm abduction radiography. Methods: We enrolled 30 patients with the diagnosis of unilateral frozen shoulder after ruling out of other pathologies. Bilateral standard should...

متن کاملStudy of wrist joint motion with dynamic radiography
Dynamic radiography had been used for motion analysis of the wrist joint since 1980s. But only limited images could be obtained with high exposure doses in conventional equipment. In recent years, advance equipment for dynamic radiography was developed, and thus, various images could be obtained with low exposure doses and without distortion. In this session, I would like to talk about our stud...
متن کاملDiagnostic Value of Chest Radiography in Pediatric Cardiovascular Diseases: A Retrospective Study in Tabriz, Northwest of Iran
Background and Objective: Chest X-ray is usually the first radiography performed for a newborn. This test is easily accessible and yet a basic screening method. Different results have been reported in various studies regarding the diagnostic value of chest X-ray in cardiovascular disease in children. Materials and Methods: The study was carried out retrospectively using the medical files of 100...
