Measurement of the left atrium (LA) size and diameters of the pulmonary vein (PV) with multi-slice spiral CT. a, b Maximum diameters of the LA in coronal and sagittal views, respectively. LA1: transverse diameter; LA2: vertical diameter; LA3: anterior and posterior diameter. c Three dimensional images of the LA and four PVs. d Maximum upper and lower diameters of the four PVs measured at the coronary view. RSPV, right superior PV; RIPV, right inferior PV; LSPV, left superior PV; LIPV, left inferior PV
