Preliminary Study on the Application of Three-Dimensional Time-of-Flight Magnetic Resonance Angiography (3D-TOF-MRA) to Observe the Cerebral Arteries in Mongolian Gerbils
Objective Establishment of a three dimensional time-of-flight magnetic resonance angiography (3D-TOF-MRA) technique for observing cerebral arteries in live Mongolian gerbils. Method 1. Employ a 7.0T MRI scanner to image the cerebral arteries of Mongolian gerbils, with data subsequently processed using the RadiAnt DICOM Viewer software;2. Validate and compare imaging results via the latex perfusion method;Attempt to perform 3D reconstruction of the posterior communicating branch and surrounding cerebral blood vessels of the Mongolian gerbil and rats through analysis software; 4. Attempt to use this method to screen individuals with abnormal vascular development in Mongolian gerbils to verify the effectiveness of this method. Result 1.The 3D-TOF-MRA technology can effectively observe the cerebral arteries of living Mongolian gerbils; 2.The 3D-TOF-MRA technology has high accuracy in observing the main cerebral arteries of Mongolian gerbils, but its observation effect on finer vascular branches is not as good as latex perfusion method; 3.The data obtained from 3D-TOF-MRA technology can be used for three-dimensional reconstruction of blood vessels; 4. The application of this technology has a good effect on screening for abnormal development of arterial structure in Mongolian gerbils. Conclusion The 3D-TOF-MRA technology can be applied to the structural observation and related research of the cerebral arteries in live Mongolian gerbils.
