ABSTRACT
14 years) in female. ICA-C4: (4.3?0.6) mm in male, (3.9?0.6) mm in female. A1 segment of anterior cerebral artery (ACA-A1): (2.1?0.4) mm in male, (2.1?0.4) mm in female. Anterior communicating artery (ACoA): (1.4?0.4) mm in male, (1.3?0.4) mm in female. M1 segment of middle cerebral artery (MCA-M1): (2.7?0.4) mm in male, (2.6?0.4) mm in female. Basilar artery (BA): (2.9?0.5) mm in male, (2.8?0.4) mm in female. P1 segment of posterior cerebral artery (PCA-P1): (2.1?0.5) mm on the left and (2.0?0.5) mm on the right in male, (2.0?0.3) mm on the left and (1.9?0.3) mm on the right in female. PCA-P2: (1.8?0.4) mm in male, (1.7?0.3) mm in female. Posterior communicating artery (PCoA): (1.1?0.3) mm in male, (1.2?0.4) mm in female. Among various diameters, only PCA-P1 had significant difference between the left and the right (P=0.003); only MCA-M1 (P=0.048), PCA-P1 (P=0.012), ICA-C2 (P=0.000) and C4 segments (P=0.000) had significant differences in gender, respectively; and only ICA-C2 had significant difference in age (P=0.001). Of these significantly different diameters, the diameters in male were larger than those in female. There were significant correlation between PCA-P1 and PCA-P2 (r=0.652,P=0.000), and between ICA-C2 and ICA-C4 in female group (r=0.550,P=0.000), respectively. Conclusions The normal values of diameter of cerebral arteries on MR angiograms may play a reference role in diagnosing cerebral vascular diseases.
