A 55-year old female was referred for an MRI brain scan following neurological symptoms, which included slurred speech and one-sided facial paralysis. Study the images below and answer the questions that follow:  AMRI TEST 1 IMAGE 2026.pngIf images A and B are DWI sequences, which sequence is image C?                                                                                                                                                [1] 2 At which diffusion gradients were images A and B obtained?                                                                                                                                              [2] 3 Evaluate the abnormality pointed by the red arrow and explain how it appears in each sequence.                                                                                                  [6]                                                                                                                                                                   4 Looking at these images, do you think a contrast agent is required or not?
