Abstract

Abstract:

Objective To explore the use of three-dimensional time-of-flight (3D-TOF) magnetic resonance angiography of the cerebral arterial circle of the display case, and to provide morphological data for 3D visualization of arterial maps of the constructed basilar arterial circle. Methods Cerebral arterial circle was measured between artery angle and distance in 10 cadavers. The images of magnetic resonance angiography were got by 3D time-of-flight (3D-TOF) from 30 cases of normal human brain and were processed by Siemens Syngo B17 workstation, from medical imaging to analyze the cerebral arterial circle.
Results Display rate of the anterior cerebral artery was 100%, bilateral arrangement. The mean distance of the artery circle was (1.06±0.23) cm, the mean angle with internal carotid artery was (63.13±9.72)°, and the mean angle of the anterior communicating artery was (107.95±57.70)°. Display rate of the internal carotid arterial was 100%, and the mean angle of the anterior cerebral artery was (63.13±9.72)°, with the mean angle of the posterior communicating artery was (123.20±10.37)°. Display rate of the posterior cerebral artery was 100%, the mean distance of the artery circle was (0.56±0.12) cm, the mean angle of the posterior communicating artery was (70.00±8.87)°, and the mean angle of the basilar artery was (123.95±11.43)°. Display rate of the posterior communicating artery was 100%, the mean distance of the artery circle was (1.06±0.17) cm, and the mean angle of internal carotid artery was (123.20±10.37)°, and the mean angle of the posterior cerebral artery was (70.00±8.87 )°, and the mean angle of the middle cerebral artery was (131.15±15.21)°. Display rate of the anterior communicating artery was 80%, the mean distance of the artery circle was (0.23±0.16) cm, and with the mean of the anterior cerebral artery angle was (107.95±57.70)°. Conclusion This study confirms the anatomical composition of the cerebral arterial circle, measured the distance between the cerebral arteries, and measured the angle between the artery circle within the artery. The results show that 3D-TOF method magnetic resonance angiography can clearly display the composition of the cerebral artery circle, and three-dimensional reconstruction techniques from different angles display the cerebral artery circle.
