If someone have lung cancer that have spread to the brain can you speak about next to an MRI?

CT scans can detect if near is a reasonably immense ("mass effect") tumor up there.
MRI can detect more subtle signs, such as inflammation cause by tumor cell invasion of brain tissues.
Also, there are two cancer syndromes that commonly have no signs on MRI, CT, or any other imaging studies. One is paraneoplastic encephalomyelitis (don't try and enunciate that all within one breath; I prefer "PNEM" myself). PNEM is technically not a cancer to the brain, it's an autoimmune reaction to the cancer, and the spontaneous effect also travels to the brain and wreaks havoc there. PNEM occur most commonly in "small-cell" lung cancer. It is diagnosable largely by blood tests, and clearly a red flag is raised contained by patients with SC lung cancer if they show neurological symptoms.
The other imaging-silent cancer complication is leptomeningeal carcinomatosis (LC), which is when cancer cell end up surrounded by the meninges (cushions) surrounding your brain. Often, the tumor cell invasion is so diffuse that no imaging can pick it up. It is a late stage cancer symptom, and by this time, patients may die sooner of the unproved cancer than they would of brain symptoms. Blood tests may detect an invisible LC situation, but diagnosis is base more frequently on the presence of neurological symptoms in late-stage non-brain cancer patients who own cancers bar SC lung.
Yes, a CT-scan and or a MRI may help, but the doctor who is treating is the best one to opt. Or seek a second evaluation if needed.
EVENTUALLY
YES! very uncommon combination, but if spread to the brain an MRI will tell, usally the those behaviour will let somebody know u that it spread..
