A 45-year-old patient presents with sudden loss of vision in the right eye. On examination, the visual acuity is reduced to hand movements in the right eye, while the left eye remains 20/20. There is a relative afferent pupillary defect (RAPD) in the right eye. Fundoscopy reveals a pale optic disc with subtle swelling. MRI of the brain and orbits shows an enhancing lesion in the right optic nerve. What is the most likely diagnosis? Optic neuritis Papilledema Giant cell arteritis Non-arteritic anterior ischemic optic neuropathy (NAION) None 2. Which of the following is true about the FLAIR sequence in MRI and its use in diagnosing multiple sclerosis (MS)? FLAIR suppresses fat signals, making white matter lesions more visible. FLAIR is ineffective in detecting lesions near cerebrospinal fluid (CSF). FLAIR enhances the visibility of periventricular lesions, a hallmark of MS. FLAIR is primarily used to assess bone structures in MRI. None 3. Which of the following MRI sequences is most useful for evaluating brain tumors and their relationship to surrounding structures? T1-weighted images with contrast T2-weighted images Diffusion-weighted imaging (DWI) Proton density-weighted images None 4. Which MRI sequence is most commonly used to detect acute ischemic stroke? T1-weighted images T2-weighted images Diffusion-weighted imaging (DWI) Gradient echo (GRE) None 5. Which structure is most likely to appear bright on a T1-weighted MRI due to the presence of fat? Grey matter Orbital fat Cerebrospinal fluid Cortical bone None You have reached the end of this quiz. Please click the Submit button to view the result.
