30.下列有關核醫腦室造影(radionuclide cisternography)診斷脊髓液鼻漏的敘述,何者錯誤?
(A)若頭部造影正常,可加照腹部,由胃部的顯影增加偵測鼻漏的機會
(B)壓迫內頸靜脈法可增加脊髓液漏出機會以減少偽陰性
(C)大部分的脊髓液鼻漏發生於車禍受傷後
(D)可於兩側鼻孔放置棉花球,等一段時間再量測其放射活性,只要有放射活性即能確定有脊
髓液鼻漏

P.255 腦池造影
In patients with CSF leakage, cotton pledgets are placed in the nostrils for
a period of 24 hr after lumbar puncture administration of 111In-DTPA, and
then removed at the end of the study. The activities in the pledgets and the
blood are measured in a well counter, and compared. If the pledget activity
is greater than the blood activity by a factor of 1.5 or more, CSF leakage
(rhinorrhea) is suspected.
棉球活性必須比血液活性大1.5倍(或是更高)才可確定是CSF鼻漏
