Removal of bolus fragmentation artifacts from pulmonary curves as applied to QP:QS shunt determination
Description
A computer method has been developed to correct errors from fragmented boluses in pulmonary time-activity curves. Improved QP:QS quantitation for cardiovascular shunt determination has been achieved in the 15 cases tested.The technique uses a series of subtractions of time-displaced minified curves from both bolus and pulmonary time-activity curves. The result is an improved bolus and lung curve that correlates very highly with QP:QS as determined by x-ray angiocardiography
