text: The<unk>  main<unk>  artery gives rise to the<unk>  anterior descending (LAD) artery and the<unk>  circumflex<unk>  (LCx) artery.  Complete visualization of these arteries and their branches requires care and rigor to ensure complete anatomical documentation.  Often bifurcations and vessel foreshortening and overlap cause errors in stenosis estimation.  There are no steadfast rules in which tomographic views are most useful.  Generally, for circumflex and proximal epicardial visualization, the caudal views are most useful.  For LAD and LAD/diagonal bifurcation visualization, the cranial views are most useful.  Overall, if there is not a significant limitation on contrast utilization, standard 'around the world' angiography using a selection of the following angiographic views will document<unk><unk>  anatomy.
option_0: Coronary angiography left coronary artery
option_1: Coronary angiography right coronary artery
option_2: Chronic stable angina electron beam tomography
option_3: Left ventricular hypertrophy echocardiography
option_4: Coronary heart disease electrocardiogram
option_5: Coronary angiography quantitative angiography
option_6: Carotid artery stenosis electrocardiogram
option_7: Carcinoid syndrome electrocardiogram
