目的 探讨高分辨率CT(HRCT)对颞部疾病的检查价值。 方法 对 43例颞部疾病患者行常规CT和高分辨率CT(HRCT)检查所获图像对比分析 ;并讨论HRCT的检查技术和图像后处理。结果 HRCT对病变的显示率及病变引起骨质破坏的程度、病变边缘、轮廓的显示均明显优于常规CT ,尤其能清楚显示常规CT难以显示的中耳及内耳的细微结构。结论 高分辨率CT是颞部疾病的首选检查方法 ,使用高分辨率CT对颞部疾病的检查给临床提供更多、更准确的诊断信息
Objective To investigate the value of high resolution CT (HRCT) in the detection of temporal diseases. Methods Forty-three patients with temporal diseases underwent contrast-enhanced CT and high-resolution CT (HRCT) examinations. HRCT examination techniques and image post-processing were discussed. Results The HRCT showed the rate of lesion and the degree of bone destruction caused by the lesion, the edge of the lesion and the outline of the lesion were obviously better than the conventional CT. In particular, the fine structure of the middle ear and the inner ear that the conventional CT was hard to show was clearly shown. Conclusion High-resolution CT is the first choice for the detection of temporal diseases. The use of high-resolution CT for the detection of temporal diseases provides more and more accurate diagnostic information
