D iffer-ent coronary atherosclerotic stenosis degree of sudden death cases w as selected. B efore the cardiac anatom y, hearts w ere rem oved out com pletely and C T angiography w as perform ed im m ediately. T he C T angiography results w ere com pared w ith histopathological findings. M eanw hile, the advantages and disad-vantages of the angiography device before and after im provem ent w ere com pared.
