摘要:目的: 探討產前超聲檢查對胎兒前腦無裂畸形的診斷及鑒別價值。 方法 :對我院產前超聲篩查中發現的17例胎兒前腦無裂畸形的超聲聲像圖及引產后的尸檢資料進行回顧性對照分析。 結果 :產前超聲診斷的17例前腦無裂畸形全部經引產后尸檢證實,顱腦異常的聲像圖表現為單一腦室、丘腦融合及腦鐮、胼胝體等中線結構缺如,大多數病例均伴有不同程度的顏面部畸形。 結論 :產前超聲對前腦無裂畸形具有重要的診斷價值,該病特有的顱腦聲像圖特征及大多伴有顏面部畸形的特點有助于診斷及鑒別診斷。Abstract: Objective: To explore the diagnostic and differential diagnostic value of prenatal ultrasound in fetal holoprosencephaly. Methods : The sonograms and autopsy data of 17 cases of fetal holoprosencephaly found in 21568 pregnant women by prenatal ultrasound were analyzed retrospectively. Results : Seventeen cases of fetal holoprosencephaly diagnosed by prenatal ultrasound and autopsy were confirmed. Characteristic ultrasound findings in holoprosencephaly included a single primitive ventricle, fused thalami, absence of midline structures such as the falx cerebri and corpus callosum, and facial abnormalities. Conclusion : Prenatal ultrasound has important value in the diagnosis of fetal holoprosencephaly. The characteristic ultrasound findings of the intracranial and facial abnormalities are helpful for the diagnosis and differential diagnosis of holoprosencephaly.
目的：評價宮腔聲學造影(SHG)對子宮內膜息肉的診斷價值。方法：對臨床擬診宮內膜息肉的76例患者進行TVS、SHG及宮腔鏡手術病理檢查，并對結果進行分析。結果：以手術病理結果作為診斷金標準，內膜息肉48例，黏膜下肌瘤9例，內膜增生10例，宮腔內機化血凝塊3例，正常內膜6例。SHG對子宮內膜息肉診斷的準確性為93.4%，敏感性為93.7%，特異性為92.8%。TVS對子宮內膜息肉診斷的準確性為59.2%，敏感性為81.2%，特異性為21.4%。兩種方法對內膜息肉的診斷準確率比較有顯著差異(χ2=5.45，P=0.019)。結論：宮腔聲學造影準確率高，是診斷子宮內膜息肉的可靠方法。
