80. 關於 HCC image diagnostic performance 的敘述，下列何者正確？
(1) Dynamic plus hepatobiliary phase MRI had a higher sensitivity and negative predictive value than multiphasic CT and dynamic phase MRI alone
(2) Gadoxetic acid is unique in that approximately 50% of the administrated dose is taken up by the hepatocytes and excreted into the bile ducts
(3) On gadoxetic acid enhanced MRI, hyper-intensity on hepatobiliary phase is regarded as an ancillary finding favoring malignancy
(4) Gadoxetic acid-enhanced MRI has a higher sensitivity for detecting nodules that are either HCC not displaying the typical features of imaging hallmarks
or high-grade dysplastic nodules
(A) (2)
(B) (1)＋(2)＋(4)
(C) (1)＋(2)
(D) (1)＋(2)＋(3)＋(4)
