Automated Quantification of Stenosis Severity on 64-Slice CT

Calculation of the Scattered Radiation Profile in 64 Slice CT Scanners Using Experimental Measurement

Introduction: One of the most important parameters in x-ray CT imaging is the noise induced by detected scattered radiation. The detected scattered radiation is completely dependent on the scanner geometry as well as size, shape and material of the scanned object. The magnitude and spatial distribution of the scattered radiation in x-ray CT should be quantified for development of robust scatter...

Quantification of carotid stenosis on CT angiography.

PURPOSE Carotid artery stenosis quantification uses percent diameter ratios from conventional angiography. Multidetector high-speed CT angiography (CTA) allows direct millimeter measurement of carotid stenosis. We hypothesize a linear relationship between millimeter stenosis measurements and derived percent, alleviating cumbersome ratio calculations. METHODS Two neuroradiologists separately r...

Use of 64 slice CT in scimitar syndrome.

INTRODUCTION Scimitar Syndrome is a relatively rare variety of partial anomalous pulmonary venous connection in which the right pulmonary veins form an anomalous confluence which drains into the infra-diaphragmatic inferior vena cava. The X-ray chest in these patients shows the typical Scimitar Sign. CASE REPORT We are presenting a patient who was diagnosed to have Scimitar Syndrome on the ba...

Lung transplant patients benefit from 64-slice CT

Lung transplantation is an accepted treatment option for patients with end-stage lung disease. The procedure can increase quality of life and prolong survival. Single-lung transplants are performed more frequently than bilateral procedures, which increases the number of transplant recipients, given the shortage of suitable donors.1,2 Complications occur frequently, however, significantly reduci...
