Progressive supranuclear palsy is a neurodegenerative disorder, mainly affecting eye movements, cognition and posture.
進(jìn)行性核上性麻痹是一種神經(jīng)退行性疾病，主要影響眼球運(yùn)動(dòng),、認(rèn)知和步態(tài),。

MRI findings of progressive supranuclear palsy are midbrain atrophy with dilated cisterns, thinning of the quadrigeminal plate, third ventricular dilatation and the characteristic hummingbird sign.
進(jìn)行性核上性麻痹的MRI表現(xiàn)為中腦萎縮伴腦池?cái)U(kuò)大、四疊體變薄,、第三腦室擴(kuò)大和特征性蜂鳥(niǎo)征,。

Hummingbird sign in progressive supranuclear palsy patients was due to atrophy of the midbrain and relative lengthening of the interpeduncular fossa and preserved pons.
進(jìn)行性核上性麻痹患者的蜂鳥(niǎo)征是由于中腦萎縮、腳間窩和腦橋相對(duì)延長(zhǎng)所致,。

Using mid-sagittal plain MRI, the hummingbird sign was demonstrated in all progressive supranuclear palsy patients but was negative in Parkinson disease and controls.
在MRI正中矢狀面,，所有進(jìn)行性核上性麻痹患者均可見(jiàn)蜂鳥(niǎo)征，但帕金森病和對(duì)照組均為陰性,。

Hummingbird sign on MRI has a sensitivity of around 100%. Hummingbird sign on MRI can be a useful diagnostic clue for physicians for confirmation of diagnosis of progressive supranuclear palsy and can help to differentiate from Parkinson disease.

在MRI,，蜂鳥(niǎo)征敏感度約為100%。蜂鳥(niǎo)征可作為進(jìn)行性核上性麻痹的有效診斷征象,，并可與帕金森病相鑒別,。

Mid sagittal MRI T2-weighted image revealing midbrain atrophy (thin arrow), and cistern dilatation with preserved pons (thick arrow) resembling a hummingbird.

正中矢狀位MRI T2加權(quán)成像顯示中腦萎縮（細(xì)箭頭），腦池?cái)U(kuò)張及腦橋（粗箭頭）,，酷似蜂鳥(niǎo),。

Close differential diagnoses of this condition are Parkinson disease, multiple-system atrophy, and corticobasal degeneration.

密切鑒別診斷包括帕金森病、多系統(tǒng)萎縮和皮質(zhì)基底變性,。
