Iodine Mapping Using Subtraction in Pulmonary Embolism CT Versus Dual-Energy CT

Comparing two techniques (Subtraction and Dual Energy CT) for functional Chest CT for patients with suspected with pulmonary embolism.

Lung Perfusion Measured With Dual-Energy CT in Patients With Chronic Thromboembolic Pulmonary Hypertension: Comparative Study With Right Heart Catheterization and V/Q

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...

Early Therapy of Pulmonary Arterial Hypertension

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 Recognition of Pulmonary Arterial Hypertension

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...

Evaluation of FDG Uptake and Pulmonary Perfusion by Positron Emission Tomography in Patients With Pulmonary Arterial Hypertension Before and After Treatment With Ambrisentan

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...

How Well Does Dual-Energy Computed Tomography With Metal Artifact Reduction Software Improve Image Quality and Quantify Computed Tomography Number and Iodine Concentration?

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).

Interscanner and Intrascanner Comparison of Virtual Unenhanced Attenuation Values Derived From Twin Beam Dual-Energy and Dual-Source, Dual-Energy Computed Tomography.

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...

Clinical and hemodynamic correlates of pulmonary arterial stiffness in incident, untreated patients with idiopathic pulmonary arterial hypertension.

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...

The role of platelets in the development and progression of pulmonary arterial hypertension.

Pulmonary arterial hypertension is a multifactorial disease characterized by vasoconstriction, vascular remodeling, inflammation and thrombosis. Although an increasing number of research confirmed tha...

Medical and Biotech [MESH] Definitions

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.
