Aortic Arch Angiogram

These images were aquired by rapid injection of iodinated contrast material through a catheter placed into the ascending aorta, with rapid sequential radiographs obtained.

The image is aquired in a left anterior oblique projection, which optimizes viewing of the arch and great vessels origins. On this image, the bones are included. On the subsequent images, the bones have been 'subtracted', which increases the conspicuity of the opacified vessels.
