Dual-energy computed tomographic imaging of pulmonary hypertension.
Dual-energy computed tomography (DECT) angiography of the chest provides a combined morphological and functional analysis of the lung, usually obtained in a single acquisition without extra radiation or injection of extra intravenous iodine contrast. The parenchymal iodine maps generated by DECT are well correlated with scintigraphy, and are becoming an essential tool for evaluating patients wi...
متن کاملDual-energy CT imaging of thoracic malignancies
Computed tomography (CT) plays a pivotal role in the detection, characterization, and staging of lung cancer and other thoracic malignancies. Since the introduction of clinically viable dual-energy CT techniques, substantial evidence has accumulated on the use of this modality for imaging chest malignancies. This article describes the principles of dual-energy CT along with suitable image acqui...
متن کاملMR and CT Imaging for the Evaluation of Pulmonary Hypertension.
Imaging plays a central role in the diagnosis and management of all forms of pulmonary hypertension (PH). Although Doppler echocardiography is essential for the evaluation of PH, its ability to optimally evaluate the right ventricle and pulmonary vasculature is limited by its 2-dimensional planar capabilities. Magnetic resonance and computed tomography are capable of determining the etiology an...
متن کاملDual energy CT pulmonary angiography: findings in a patient with chronic thromboembolic pulmonary hypertension.
A 55-year-old woman became increasingly breathless over a 9month period. Systolic pulmonary artery pressure was estimated at 50 mm Hg by echocardiography. CT pulmonary angiography was performed using a dual energy technique whereby datasets are simultaneously acquired at 80 kV and 140 kV. Differential absorption of these energy spectra by iodine molecules in intravenous contrast medium is explo...
