Comparison of intravascular ultrasound and quantitative coronary angiography for the assessment of coronary artery disease progression.
BACKGROUND The relative merits of quantitative coronary analysis (QCA) and intravascular ultrasound (IVUS) for the assessment of progression/regression in coronary artery disease are uncertain. To explore this subject further, we analyzed the angiographic and IVUS data derived from a contemporary clinical trial population. METHODS AND RESULTS We investigated the relationships between QCA and ...
متن کاملCoronary intravascular ultrasound.
C oronary angiography remains an important modality for assessing atherosclerotic coronary artery disease and guiding percutaneous coronary intervention. Intravascular ultrasound (IVUS) is an important adjunct during coronary angiography and has been increasingly used in clinical and research applications in the past decade. It has vastly enhanced our understanding and has provided us with a th...
متن کاملSerial Intravascular Ultrasound Assessment of Coronary Atherosclerosis Progression and Remodeling
Background: The relation between serum lipids and risk of coronary events has been established, but there are no data demonstrating directly the relation between serum low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol versus serial changes in coronary plaque dimensions. Methods and Results: We performed standard analyses of serial intravascular ultrasound ...
متن کاملA comparative approach of four different image registration techniques for quantitative assessment of coronary artery calcium lesions using intravascular ultrasound
In IVUS imaging, constant linear velocity and a constant angular velocity of 1800 rev/min causes displacement of the calcium in subsequent image frames. To overcome this error in intravascular ultrasound video, IVUS image frames must be registered prior to the lesion quantification. This paper presents a comprehensive comparison of four registration methods, namely: Rigid, Affine, B-Splines and...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
