Calculation of accurate stroke count ratios for the assessment of valvular regurgitation from equilibrium blood pool images has been difficult and did not permit computation of regurgitant fractions (RF) because of contamination of right ventricular (RV) stroke counts by right atrial activity. We describe a new approach to correct for this contamination by subtracting one half of the right atrial counts from the RV counts, assuming that in the standard or "modified" left anterior oblique… CONTINUE READING
