Disease relevance of Tomography, X-Ray Computed

OBJECTIVES: The high sensitivity of electron beam tomography (EBT) in the detection of coronary artery calcium (CAC) and obstructive coronary artery disease prompted us to investigate the association between CAC detection and future cardiac events in patients with acute chest pain syndromes requiring hospitalization [1].
A case of cor triatriatum in a 51-year-old man was demonstrated by rapid acquisition cine-CT (CCT) [2].
Appropriate axial or coronal computed x-ray tomography is the most inexpensive method to reliably supply detail in orbital disease [3].
Antioxidant intake was assessed with the Block Dietary Questionnaire, and coronary atherosclerosis was identified by measuring coronary artery calcification using electron beam computed tomography [4].

High impact information on Tomography, X-Ray Computed

Ethnic origin and serum levels of 1alpha,25-dihydroxyvitamin D3 are independent predictors of coronary calcium mass measured by electron-beam computed tomography [5].
Usefulness of electron-beam computed tomography in arrhythmogenic right ventricular dysplasia. Relationship to electrophysiological abnormalities and left ventricular involvement [6].
BACKGROUND: Coronary calcium identified by electron-beam computed tomography (EBCT) correlates poorly with luminal atherosclerotic narrowing, but calcium, an intimate part of coronary plaque, may be more directly related to atheromatous plaque area [7].
Renal hemodynamics and function were quantified in vivo using electron-beam computed tomography at baseline and after vasodilator challenge using acetylcholine [8].
The RV standardized uptake value (SUV) of FDG was corrected for the partial volume effect based on the wall thickness measured by electron-beam computed tomography or magnetic resonance imaging [9].

Biological context of Tomography, X-Ray Computed

Myocardial perfusion and vascular permeability were measured in vivo using electron beam computed tomography before and after cardiac challenge with intravenous adenosine [10].
Renal blood flow was measured with electron-beam computed tomography before and during infusion of acetylcholine (Ach) [11].
Myocardial microvascular function (blood volume and blood flow at baseline and in response to adenosine) was assessed by using electron beam computed tomography (CT) [12].

Anatomical context of Tomography, X-Ray Computed

Because lipoproteins, angiotensin-converting enzyme, and angiotensin II colocalize with calcium in aortic valve lesions, we hypothesized an association between angiotensin-converting enzyme inhibitor (ACEI) use and lowered aortic valve calcium (AVC) accumulation, as measured by electron beam computed tomography [13].
METHODS: (99m) Tc-sestamibi SPECT/X-ray-CT was performed by gamma camera-mounted anatomical X-ray tomography (GMAXT; GE Medical systems, Millenium VG with Hawkeye) in four patients with ectopic parathyroid glands (two patients with primary, two with persistent secondary hyperparathyroidism) [14].
We designed an uncollimated non-uniform line array source (non-uniform LAS) for attenuation correction based on transmission computed tomography (TCT) using Tc-99m and compared its performance with an uncollimated uniform line array source (uniform LAS) in a thorax phantom study [15].

Associations of Tomography, X-Ray Computed with chemical compounds

Electron beam tomography and National Cholesterol Education Program guidelines in asymptomatic women [16].
Subsequently, cardiac electron beam computed tomography was performed before and during intravenous infusion of adenosine and dobutamine, and MP and PI were calculated [17].
CONCLUSIONS: Electron beam computed tomography has a higher diagnostic ability than either treadmill-ECG or technetium-stress for the detection of obstructive angiographic CAD [18].
Agatston coronary artery calcium (CAC) score, as a marker of coronary artery calcification, was obtained using electron-beam computed tomography [19].
Renal regional perfusion and intratubular contrast media concentration in each nephron segment (representing fluid reabsorption) were quantified in vivo with electron-beam computed tomography before and after a suprarenal infusion of either acetylcholine (6 pigs of each diet) or sodium nitroprusside (SNP; 5 pigs of each diet) [20].

Gene context of Tomography, X-Ray Computed

Matrix Gla protein is associated with coronary artery calcification as assessed by electron-beam computed tomography [21].
Clinical characteristics, homocysteine, lipids, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and coronary artery calcification as detected by electron beam computed tomography were measured [22].
Usefulness of electron beam computed tomography scanning for distinguishing ischemic from nonischemic cardiomyopathy [23].
METHODS: In a prospective, cohort study of type 2 diabetic individuals (N = 90; normoalbuminuric diabetic controls, 30; diabetic nephropathy, DN, 60), electron-beam computed tomography (EBCT) was repeated at an average interval of 19 months [24].
METHODS: Electron beam tomography (EBT) was performed in 75 female patients with SLE aged <50 [25].

Analytical, diagnostic and therapeutic context of Tomography, X-Ray Computed

Technetium-99m-HMPAO brain SPECT and x-ray-CT scans were acquired [26].
Patients were examined by x-ray (transmission) computed tomography (CT) and by radionuclide (emission) computed tomography (RCT) prior to and during a course of dexamethasone therapy [27].
METHODS: We used electron beam tomography (EBT) to quantitate CC in 168 symptomatic (chest pain or anginal equivalent) persons with diabetes who underwent coronary angiography and then compared this with a cohort of 155 asymptomatic persons with diabetes [28].
Prior cross-sectional studies also showed that high BMI in CKD is associated with higher C-reactive protein (CRP) levels and increased coronary calcification on electron beam computed tomography (CT) scan [29].
HYPOTHESIS: The study was undertaken to evaluate the diagnostic ability of echocardiography and electron beam tomography (EBT) to differentiate between ischemic and nonischemic cardiomyopathy [30].
