What Does The Following Result From MRI Indicate?

Is it possible to tell the difference between calcium and a foreign body on a CT scan? on an MRI? My MRI says susceptibility the CT says punctate hyperdense focus (could represent focus of calcium or a foreign body)...what does this mean?

Welcome to health care magic.

1.MRI is not good in presence of foreign body - as it may give artefact ( reflections ) and even in case of calcium MRI is not a recommended modality.
2.CT is good to differentiated from a calcium and a foreign body, As hyper dense foci in case of calcium ( the difference is made with HU values)
3.X-ray will be best to differentiate initially cheap and less radiation.
4.Foreign body is seen as radio dense opacity on x-ray.
5.Depending on the size and location of object - X-ray and CT will be best. Good luck.

Hope i have answered your query,
any thing to ask do not hesitate to ask.
