ABSTRACT
BACKGROUND: Rapid advances in multislice computed tomography (MSCT) technology facilitate accurate clinical imaging. The newly developed 64-slice CT increases temporal and spatial resolution efficiently. PURPOSE: The purpose of this study is to evaluate the application of 64 slice spiral computed tomography (CT) on the imaging of the normal optics canal. METHODS AND MATERIALS: 100 healthy adults were investigated using 64 slice spiral CT. The optics canal was scanned, reconstructed and examined. RESULTS: Among the four walls of the optic canal, the medial wall is the longest one. The upper wall and outer wall are inferior to the medial wall while the inferior wall is the shortest one. All the data accomplished by the 64 slice CT was consistent with the results of previous reports using other methods. CONCLUSION: The results suggested that the 64 slice spiral CT could be a valuable and accurate method for measuring the length of optics canal walls.
