【摘要】：目的測量20~37周正常胎兒標本第四頸椎(C4)椎體各參數(shù)隨孕周變化的規(guī)律,完善胚胎脊椎發(fā)育影像解剖數(shù)據(jù)。方法利用3.0T磁共振對41例20~37孕周(男,21例;女,20例)胎兒標本行3D-T_2WI和T_2WI-SPC序列掃描,測量不同孕周C4椎體生長參數(shù)并行統(tǒng)計分析,得出各參數(shù)隨孕周變化的曲線。結果 C4椎體的各參數(shù)的變化隨孕周變化呈線性相關,不同性別在各參數(shù)中無統(tǒng)計學差異。結論 C4椎體作為典型中位頸椎椎體的代表,其動態(tài)生長發(fā)育呈線性增長趨勢,與胎齡相關的C4椎體的生長參數(shù)參照區(qū)間對評估先天性脊柱發(fā)育缺陷有重要參考價值。
