BACKGROUND Coronary CT angiography (CCTA) allows accurate evaluation of coronary artery stenosis but has limitations in information on hemodynamic significance of stenotic lesions. PURPOSE To determine the feasibility of adenosine-stress low-dose single-scan CT myocardial perfusion imaging (MPI) using a 128-slice dual-source CT scanner for the diagnosis(More)
The noninvasive assessment of coronary stents by coronary CT angiography (CCTA) is an attractive method. However, the radiation dose associated with CCTA remains a concern for patients. The purpose of this study is to compare the radiation doses and image qualities of CCTA performed using tube voltages of 100 or 120 kVp for the evaluation of coronary(More)
Hemorrhage is a finding of clinical fat embolism syndrome. The purpose of the present study was to evaluate the occurrence of hemorrhage in the cat brain by SW MR imaging after infusion of triolein as a bolus or as an emulsion into the carotid artery. Twenty-two cats were divided into two groups according to the type of triolein infused: group 1 (n = 11)(More)
BACKGROUND Triolein emulsion infusion into the brain produces transiently increased vascular permeability. OBJECTIVES The purpose of this study was to find the minimum percentage of triolein emulsion required for studying vascular permeability with minimal brain edema. MATERIALS AND METHODS Sixty healthy cats were divided into six groups according to(More)
