[|Human|] A friend of mine went for an MRI to determine if cancer had spread to the brain.  After he received the injection the medical team did not realize his jaws were locked and he was foaming at the mouth.  He was at an imaging center & had to call for ambulance which for some reason took approx 15 min.  They didnt even begin CPR until the ambulance arrived.  He had no heartbeat or pulse but when they got him to hospital they were able to get his heart started again but he never regained consciousness and died 8 hours later.  What could have gone wrong?
[|AI|]  Hi, you have not mentioned the type of cancer your friend had? Because the spread of cancer to brain depends on the site and type of cancer. The injection I.e. the contrast agent used for MRI scanning is unlikely(but very rare) to cause the symptom which appears to me with the above description as a convulsion. The convulsions may also be caused by a spread of cancer to brain. The only caution should have been to start the patient on anticonvulsant for the patients who are at risk for the same. The convulsion may also lead to death. Hope I have answered your question.
