Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Definitely call the Dr on call now.. ### Response: Your symptoms would not match anything you described may or may not be on your MRA images. That being said besides vascular anomalies nothing else can be commented on in an MRA. So seeing dark or light things outside of the vessels does not mean anything, that's what the MRI is for..
