[|Human|] Yes, My father whom is 76, has metastatic melanoma, which went into his lungs, he is being treated with ipilimumab, he also has cardio vascular problem, along with being diabetic , he fell the other night, his INR was 3.6, they told us to take him to the ER and they did a CT scan, which found 2 spots on this brain, they said that they could not tell if he had bleeding on the brain or if they were calcium deposits. Question one is why could they not tell the difference? and from what I have been reading calcium deposit are not that great either. They just did a second cat scan, which shows them being calcium deposits Between his Oncologist and Neurologist were debating on either a CT scan or an MRI which one should he have. He also, has been running a fever between 100 and 102 degrees.
[|AI|]  Hi, Thank you for posting your query. I have noted your fathers symptoms and the CT scan findings. It is fairly easy to differentiate calcium deposits from bleeding in the brain on a CT scan of brain. We need to use the Hounsefield unit values which can be done on the console in CT room. In any cases, CT scan s the modality of choice for detecting both calcium deposits and bleeding in brain. However, in research studies, MRI brain is supposed to be superior for studying bleeding in the brain. I hope my answer helps. Please get back if you have any follow-up queries or if you require any additional information. Wishing you good health, Chat Doctor. Ly/
