We evaluated a new, subsecond high-pitch scan mode (HPM), which obviates the need of sedation and to hold the breath. Read more

Optimal Systolic and Diastolic Reconstruction windows for Coronary CT Angiography using Dual Source CT

posted by Harald Seifarth, M.D. | Nov 30, 2007
Harald Seifarth, M.D.

Abstract Objective: The purpose of this study was to determine the position of the optimal systolic and diastolic reconstruction interval for coronary CT angiography using Dual-Source-CT (DSCT). Materials and methods: In 90 patients, coronary DSCT angiography was performed without a prescan administration of beta blocking agents. Data were reconstructed in 5 % … Read more
