Pet Scan Vs Mri Brain Cancer
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Unlikely.: Always possible, but very low probability. Currently, MRI is the most sensitive imaging test of the head (particularly in the brain) in routine clinical practice. PET scans are another imaging modality that an oncologist can decide to perform if there is a high index of suspicion even after the negative MRI in some individualized cases. ...Read more

Probably tumor: It is hard to understand your question. If there are new 'lumps' in the brain as seen with mri, these would likely be interpreted as progressive tumor, and one would not suggest the chemotherapy is working well. You need to ask for a detailed explanationfrom the doctors, or perhaps seek second opinions. ...Read moreSee 1 more doctor answer

Will an MRI scan show up any form of cancer, bacterial or viral infection? Mri - brain, spine & pelvis. Had pnuemonia. Can't find infection. Autoimmu?
Disequilibrium x1 week - only sometimes when walking. Feel off balance. Normal MRI of brain 6 months ago. So scared this is a brain tumor? 27/F.
Consider other cause: Since you had an MRI of the brain 6 months ago, and it was normal, you should not think of brain tumor as the cause here. Other causes are more likely and more common. These could be medicine side effects, changes in the sensation of the feet, changes in the inner ear sensation of movement, or changes with your strength. Hope that helps! ...Read more
Off balance/disequilibrium off and on when walking x2 weeks. worse after driving. MRI of brain normal 6 months ago. Worried of brain tumor. 27/F.
Dizziness, nausea x3days. Just over a cold, Dr said fluid in ears, but shouldn't cause this? MRI of brain 6 months ago. Brain tumor? Scared. 27/F.
No tumor: URI can produce some inflammation of inner ear. This results with fluid behind ear drum which if symptomatic should be drained. The fluid could induce pressure on semicucular canals and result in dizziness and well if pressure reaches brances of vagus n. then nausea can result. MRI of brain must have had a reason but if proved neg. the indications for scan were ruled out. ...Read more
MRI brain came back normal but have Mucosal thinkening and polyps what's that mean ? Tumors ? Cancer ?
Sinusitis - repeated: Mucosal thickening (of layer covering the sinuses) & sinus polyps may point to multiple attacks of sinusitis. Sinus polyps, in particular, point to allergic sinusitis. (Are you allergic to many things? Aspirin?). Unless the polyps block the sinus passages, little is done for them. Without symptoms, not much to do aside from treat allergies. It's a complex situation - use Healthtap Prime to discuss ...Read more
Had 3 ct scans of my brain when I was 15 I am 18 now and very scared that the scans are going too cause brain cancer ?
Unknown: CT of the brain does deliver radiation but the likelihood of developing malignancy from one or two studies is unknown. One must weigh the benefit to be gained from the study against whatever risk may be present. Careful selection of patients, particularly children is important when considering imaging. Thanks for trusting HealthTap! ...Read moreSee 1 more doctor answer
Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
