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 fora period of 24 hr after lumbar puncture administration of 111In-DTPA, andthen removed at the end of the study. The activities in the pledgets and theblood are measured in a well counter, and compared. If the pledget activityis 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...
