The purpose of this study is to determine the range of maximal diaphragmatic crural thickness during different phases of respiration and to correlate crural thickness with age and gender. Prospective evaluation of computed tomographic (CT) scans of 200 patients without juxtacrural abnormalities was performed. Maximal short-axis crural thickness measurements were determined in all patients. Measurements were obtained at full inspiration during chest CT (n = 60), full expiration during abdominal CT (n = 89), and unknown phase of respiration during dynamic CT scans (n = 51). Maximal crural thickness measurements were analyzed by side, age, and gender. The right crus was thicker than the left crus in 91% of patients. The range of maximal crural thickness remained fairly constant from the second to the eighth decades of life. The range of maximal crural thickness was 1.8-18.8 mm in men and 1.8-21.1 mm in women. Maximal crural thickness does not significantly vary with age and gender for specific phase of respiration.
本研究的目的是确定呼吸不同阶段膈脚最大厚度的范围，并将膈脚厚度与年龄和性别相关联。对200例无膈脚旁异常的患者进行了计算机断层扫描（CT）的前瞻性评估。测定了所有患者膈脚短轴最大厚度。在胸部CT全吸气时（n = 60）、腹部CT全呼气时（n = 89）以及动态CT扫描呼吸阶段未知时（n = 51）进行测量。对膈脚最大厚度测量值按侧别、年龄和性别进行分析。91%的患者右侧膈脚比左侧膈脚厚。从生命的第二个十年到第八个十年，膈脚最大厚度范围保持相当恒定。男性膈脚最大厚度范围为1.8 - 18.8 mm，女性为1.8 - 21.1 mm。在特定呼吸阶段，膈脚最大厚度不会随年龄和性别显著变化。
