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...

Perfusion and Dual Energy Computer Tomography in Hepatocellular Carcinoma

The aim of this study is to evaluate the hepatic perfusion computer tomography and dual energy computer tomography in the assessment of tumor characterization of Hepatocellular carcinoma i...

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...

Navigating the Pulmonary Perfusion Map: Dual-Energy Computed Tomography in Acute Pulmonary Embolism.

Pulmonary embolism is the third most common acute cardiovascular disease. Dual-energy computed tomography perfusion imaging is a promising adjunct in the detection of acute PE providing simultaneous f...

Heterogeneous Pulmonary Perfusion on Dual-Energy Computed Tomography: Faulty Postprocessing or New Artifact?

Iodine uptake in the lungs and intrathoracic lesions on postcontrast dual-energy computed tomography is used for evaluation of pulmonary embolism-related perfusion defects and pulmonary infarctions. I...

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...

In Vivo Analysis of Urinary Stones With Dual-Energy Computed Tomography.

Formation mechanisms and treatment of the urinary stones are different, depending on their chemical structure. Therefore, determining the stone type plays a key role in planning treatment and preventi...

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...

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.
