Improved Delineation of Pulmonary Embolism and Venous Thrombosis Through Frequency Selective Nonlinear Blending in CT

posted by | Jul 20, 2017

The aim of this study was to test the hypothesis that a novel frequency selective nonlinear blending (NLB) algorithm increases the delineation of pulmonary embolism and venous thrombosis in portal-venous phase whole-body staging computed tomography (CT). Read more

posted by U. Joseph Schoepf, M.D. | Aug 18, 2015
U. Joseph Schoepf, M.D.

This review will discuss the technical improvements for imaging peripheral pulmonary arteries, the methods of assessing pulmonary embolism (PE) severity based on CT findings, a multidetector CT technique for PE detection, and more. Read more

70 kVp CTPA: Potential for Reduction of Iodine Load and Radiation Dose

posted by Julian L. Wichmann, M.D. | Apr 24, 2015
Julian L. Wichmann, M.D.

The purpose of the study was to evaluate 70 kVp dual-source CTPA with reduced iodine load in comparison with single-source 70 and 100 kVp CTPA with standard iodine load regarding image quality and radiation dose. Read more
