Different brain imaging techniques play an important role in diagnosing brain tumors (for example, magnetic resonance imaging (MRI) and computed tomography (CT) scans).
Which one of the following statements is CORRECT?
In both MRI T1 and T2 image, the abnormal tumor-affected areas look brighter.
MRI T2 image can be enhanced by intravenous gadolinium, a contrast medium or a dye.
MRI T1 image can be used to detect brain lesions and water content (cerebrospinal fluid and blood), which are brighter.
Only MRI, not CT scan, can be used to measure tumor’s size.
