Computed Tomography Total Airway Count Is Associated with the Number of Micro–Computed Tomography Terminal Bronchioles

The airway response to deep inspirations decreases with COPD severity and is associated with airway distensibility assessed by computed tomography.

In patients with mild chronic obstructive pulmonary disease (COPD), the effect of deep inspirations (DIs) to reverse methacholine-induced bronchoconstriction is largely attenuated. In this study, we tested the hypothesis that the effectiveness of DI is reduced with increasing disease severity and that this is associated with a reduction in the ability of DI to distend the airways. Fifteen subje...

Extraction of Airway in Computed Tomography

Total coronary artery plaque burden measured by cardiac computed tomography is associated with metabolic syndrome.

AIM Increased coronary plaque burden, which could be involved in the pathogenesis of atherothrombotic events, is difficult to evaluate in the three major coronary arteries. The purpose of this study was to quantify coronary plaque volume using 64-slice computed tomography (CT). METHODS We measured coronary plaque volume with our new protocol in 23 consecutive patients (48% men; 66 ± 11 years ...

Computed tomography anomalies associated with isolated hypoparathyroidism

Hypocalcemia due to chronic hypoparathyroidism presents with nonspecific symptoms. However, if untreated, hypocalcemia may affect neurological, cognitive, muscular, and cardiac function. Computed tomography (CT) findings may confirm a diagnosis of chronic hypoparathyroidism. Although autoimmune acquired hypoparathyroidism is a rare disease, early diagnosis and treatment are critical for avoidin...

Vascular Inflammation Evaluated by [18F]-Fluorodeoxyglucose-Positron Emission Tomography/Computed Tomography Is Associated With Endothelial Dysfunction.

OBJECTIVE Endothelial dysfunction is an initial step in atherosclerotic cardiovascular disease. However, involvement of vascular inflammation in endothelial dysfunction is not fully investigated in humans because of the lack of diagnostic modality to noninvasively evaluate vascular inflammation. We assessed the relationship between endothelial function and vascular inflammation evaluated by [(1...
