Coronary angiography standard views
Standard Angiographic Views
For the beginner angiographer the anatomic landmarks formed by the spine, catheter and diaphragm provide information to discern which tomographic view from which the image is obtained. In the LAO view (figure 1) the catheter and spine are seen on the right side of the image, while in the RAO (figure 2) they are found on the right. PA imaging (figure 3) places these landmarks in the center of the image. Cranial angulation can usually be distinguished from caudal angulation by the presence of the diaphragm. For cranial imaging, the patient should be asked to inspire to remove the diaphragmatic shadow from the image.
