Multidetector computed tomographic pulmonary angiography: beyond acute pulmonary embolism.
Although multidetector computed tomographic (MDCT) pulmonary angiography has found widespread use in the evaluation of acute pulmonary embolism, advances in technology have allowed for its application in realms that were previously exclusive to conventional pulmonary angiography. In this article, the authors address the use of MDCT in the evaluation of chronic thromboembolic pulmonary hypertension and pulmonary arteriovenous malformations. These examples demonstrate the potential for MDCT to expand the use of computed tomographic angiography in the evaluation of the pulmonary arteries. Technical parameters, diagnostic findings at MDCT, and therapeutic implications of such findings are discussed for each condition.
