Development and utilization of measurement techniques on DSA processing system / 介入放射学杂志

ABSTRACT

Objective To evaluate the development and utilization of measurement techniques on DSA postprocessing system in interventional radiology. The POLYTRON 1000 VR DSA machine from Siemens Corporation was served as an example for the evaluation. Method The data assessed included the correlated factors of measurement techniques, utilization of original computer information, sequences of measurement and effects of technique application. The different measurement techniques were applied according to the clinical needs. The measurement results of tumors were compared on those of ultrasonography, CT and DSA image in 20 patients with hepatocellular carcinomas. The most frequently applied data were the measurements of distance, degree of vascular stenosis and functions of cardiac ventricle. Result and Conclusion The sizes measured on DSA is significantly differ from those on ultrasonography and CT. The proper measurement techniques can be applied for interventional radiology in DSA postprocessing system.
