FPnotebook.com is a rapid access, point-of-care medical reference for primary care and emergency clinicians. Each radiology department will have a slightly different method for achieving the same outcome, i.e. The quality and accuracy of imaging is demonstrated by representative examples. Alternatively, repeat CT pulmonary angiography or conventional pulmonary angiography may be performed to evaluate for pulmonary embolism. The pulmonary vasculature may be evaluated with various invasive and noninvasive methods. CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries.Its main use is to diagnose pulmonary embolism (PE). Computed tomography pulmonary angiography (CTPA) is currently the preferred thoracic imaging test for patients suspected of having pulmonary embolism (PE) [ 1 ]. Indications for coronary angiography Coronary angiography involves the opacification of the lumen in coronary arteries and acquisition of this luminogram under fluoroscopy. and you may need to create a new Wiley Online Library account. Pulmonary angiography is performed to evaluate blood circulation to the lungs. In 1997 the British Thoracic Society (BTS) published advice entitled “Suspected acute pulmonary embolism: a practical approach”.1 It was recognised that it would need updating within a few years. In this chapter, these aspects of pulmonary angiography are described. Although radiologic examination of the pulmonary vascular tree has been performed since the middle of the 1930s, pulmonary angiography has only been a routine diagnostic procedure for the last 15 years. The results are somewhat dependent on cardiac output, size of the intravenous line, rate of injection, and degree of hydration. Pulmonary angiography has become a routine procedure in most hospitals as part of the evaluation of patients for pulmonary embolism [1–3]. Working off-campus? Nevertheless, it is important that one knows the technique, pitfalls and complications of this imaging technique. Imaging of the coronary arteries requires high temporal and spatial resolution.
