Abstract:
Objective To study the scan technique that can completely demonstrate the structures of middle-inner ear.Methods Ninety volunteers underwent 30° axial and 105° coronal HRCT scan.The manifestations of the ministructures of middle-inner ear were observed and their demonstration rate was calculated.The demonstration of different structures of middle-inner ear was evaluated and compared on HRCT.Results (1)The scan planes of 30° axial and 105° coronal were correspondent to some structures of middle-inner ear and could completely demonstrate them.(2)30° axial and 105° coronal HRCT scan had their own advantages respectively in demonstrating the structures of middle-inner ear.Conclusion The technique of 30° axial and 105° coronal HRCT scan of middle-inner ear is useful in demonstrating the structures,including the nerve,joint,ligament etc and the relationship among them.
