A 42-year-old female was referred for an MRI of the brain following episodes of epileptic falls with an unknown cause. Study the two images obtained and answer the questions that follow: Picture5 PAPER 1 2025.png 1. Identify the two sequences and planes shown in the images                                                                      [2] 2. Describe the abnormalities noted in both images pointed by arrows                                    [3]

1. Discuss the clinical considerations and protocols that must be implemented when performing MRI scans in pediatric populations compared to adults. What specific challenges should be addressed?                                                                                                                                                 [4]
