Comparing two techniques (Subtraction and Dual Energy CT) for functional Chest CT for patients with suspected with pulmonary embolism.
A comparative, observational, cross-sectional and prolective diagnostic test study, including patients that have had a right heart catheterization and were referred for a CT pulmonary angi...
Exercise-induced increase of the pulmonary arterial pressure may be an early sign of pulmonary arterial hypertension. It has been shown that patients with normal pulmonary arterial pressur...
The early detection of pulmonary arterial hypertension may help to improve prognosis of the disease. It is assumed that in the early stages of pulmonary arterial hypertension, pulmonary ar...
We are doing this research study to find out how blood flow changes in the lungs of people with pulmonary hypertension before and after treatment with ambrisentan (sold under the brand nam...
The objective of this study was to assess the accuracy of the quantitative measurements obtained using dual-energy computed tomography with metal artifact reduction software (MARS).
The aim of the current study was to evaluate the reliability and comparability of virtual unenhanced (VUE) attenuation values derived from scans of a single-source, dual-energy computed tomography usi...
Dual-Energy Computed Tomography-Based Iodine Quantitation for Response Evaluation of Lung Cancers to Chemoradiotherapy/Radiotherapy: A Comparison With Fluorine-18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography-Based Positron Emission Tomography/Computed Tomography Response Evaluation Criterion in Solid Tumors.
The objective of this study was to investigate the correlation between dual-energy computed tomography (DECT)-based iodine quantitation and fluorine-18 fluorodeoxyglucose (F-FDG) positron emission tom...
The role of decreased pulmonary arterial (PA) compliance (C), equivalent to increased PA stiffness (1/C) as a critical determinant of right ventricular dysfunction and prognosis has been emphasized in...
Pulmonary arterial hypertension is a multifactorial disease characterized by vasoconstriction, vascular remodeling, inflammation and thrombosis. Although an increasing number of research confirmed tha...
An imaging technique using a device which combines TOMOGRAPHY, EMISSION-COMPUTED, SINGLE-PHOTON and TOMOGRAPHY, X-RAY COMPUTED in the same session.
Computed tomography where there is continuous X-ray exposure to the patient while being transported in a spiral or helical pattern through the beam of irradiation. This provides improved three-dimensional contrast and spatial resolution compared to conventional computed tomography, where data is obtained and computed from individual sequential exposures.
Computed tomography modalities which use a cone or pyramid-shaped beam of radiation.
Tomography using x-ray transmission and a computer algorithm to reconstruct the image.
Tomography using radioactive emissions from injected RADIONUCLIDES and computer ALGORITHMS to reconstruct an image.
