Cardiac MRI and gross image of the large atrial masses. A Short-axis inversion recovery early-enhancement image obtained with inversion time of 600Â ms and demonstrated two large clots within RAA and LAA (arrowheads) which are low signal (dark) on the image. B This montage shows the two atrial masses after surgical resection. C This image illustrates the main body of the two masses
