Quantitation of shunting at the atrial level using rapid acquisition computed tomography with comparison with cardiac catheterization
Contrast-enhanced rapid acquisition computed tomography was employed to quantitate intracardiac shunts in two adult patients.

Summary: | Contrast-enhanced rapid acquisition computed tomography was employed to quantitate intracardiac shunts in two adult patients. Contrast medium was injected through a median antecubital vein and data were accumulated using the R wave-triggered flow mode. Timedensity curves from a region of interest were generated by a gamma variate fit method and areas under the curves were calculated. Comparisons of calculated left to right shunts (Cases 1 and 2) with results of computed tomography and right to left shunt (Case 2) with cardiac catheterization data resulted in close agreement. This is the first report of quantitation of intracardiac shunts at the atrial level in humans by rapid acquisition computed tomography. |
