摘要
目的 探讨一种无创性的尺桡骨远端干骺端的影像学检测方法。方法 随机选择 12 4名正常小儿 ( 0~2 4月 ) ,对其进行双侧尺、桡骨远端干骺端的高频超声检测研究 ,同时对其中 112名小儿 ,在家长同意下进行双腕X线平片及血生化检查 [包括钙 (Ga+ + )、磷 (P)、碱性磷酸酶 (ALP) ]。结果 小儿尺桡骨远端干骺端高频超声显示率达 10 0 %。正常小儿尺桡骨骨骺呈现低回声 ,干骺端横切为一弧形强光带伴后方回声衰减 ,纵切为光滑的强回声带 ;干骺端领为一短线状强回声 ,干骺端领宽度为 1.0~ 3 .0mm ,继发骨化中心出现者 ,核距 (继发骨化中心至干骺端的距离 )为 0 .9~1.4mm。结论 高频超声可以用于小儿尺桡骨干骺端检测及其疾病筛查。
Objective To investigate a method without harm to examine metaphyses of distal radius and ulna.Methods Choose randomly 124 normal infants(0~24m) and detect their metaphyses of bilateral radius and ulna using high frequency ultrasound, meanwhile 112 case(with permission of their parents) of them were examined by bilateral wrists X-ray and biochemistry include calcium (Ca ++ ), phosphor (P), alkaline phosphatase (ALP).Results 100 percent metaphyses of distal Radia and Ulna could be revealed in focus in normal infants. Epiphysis show lower echo with small spots, its size enlarge with the baby's month increasing and shape no changing. Metaphyseal collar shows as a shorter string strong echo. The normal width of metaphyseal collar is 1.0~3.0 mm, After the second ossification centre appeared, the core distance is 0.9~1.4 mm.Conclusion High- frequency ultrasound can be used in examination of metaphyses of distal radius and ulna of normal infant.
