Avatar f tn Is it necessary to have more than one MRI scan done. I have only ever had the one scan, 15 yrs ago which was when I was given my official dx, despite having several episodes/relapses since. Initially told I had RRMS now being told I have SPMS with relapses.
Avatar n tn my doctor said i need an mri scan as a result of suffering with many symptoms for many months- he said i will receive a letter. does this mean he will book it for me or refer me? i live in the uk. anyone know anything about this?

Avatar f tn Hi, last year I had an MRI scan. I was having it as the Dr was looking to see if I had an AVM on the brain, I get a lot of headaches and have an AVM on my right forearm. When I went to see the Dr he told me my results, he said there is a malformation there but it isnt an AVM. He then pointed to the temporal lobes and said they are low. I should of asked him what that meant, but I never ask questions when Im there, I just say to myself I should of asked this and I should of asked that.
Avatar f tn i had an mri scan and was told i had a right A1 segment hypoplastic. what does this mean please?
Avatar n tn I understand these should be avoided while pregnant, but what if they are medically necessary? Has anyone gotten an MRI or Cat Scan while pregnant? What was the outcome, did it have an affect on your baby? Was it worth it? I have been experiencing agonizing pain in my left shoulder, neck, and arm, that sometimes radiates to my chest, making it hard to breathe. I am having a really hard time sleeping, and even functioning, and my quality of life has gone down because of it.
1831846 tn?1318378596 on the 18th of this month, where I will be demanding an MRI and referral to a specialist. But the CT scan states no evidence of intracranial hemorrhage, ventricular system is normal in size and configuration, withough evidence of hydrocephalus. No discrete parenchymal masses nor evidence of mass effect. There is a slight inferior displacement of the cerebellar tonsils, suggesting a mild chiari 1 malformation. No extra-axial blood or fluid collections are identified.
Avatar n tn I had a brain mri scan for recurrent 'auras' thought to be due to migraine. The result of the scan came back normal except for a few spots of plaques. I am 50, is this normal? I am concerned that it is indicative of early degeneration associated with dementia.
492898 tn?1222243598 (which I already had had, but niot specifically for the liver) From the MRI scan, ultrasound was recommended and there were only 2 lesions seen and smaller. The pathologist does not know if these are possibly metastatic, or cystic. He mentions that there is poor contrast opacification of the solid organs. small bilateral pleural effusion al;sp seen. One is one low density lesion, and another may have some peripheral enhancement.
Avatar f tn I recently had an MRI scan which has shown a cystic lesion in the right temporal lobe with surrounding hyperintensity ?due to oedema or gliosis. May represent a ganglion cell tumour. My symptoms have been over a period of ?2-3 yrs an odd sensation of disassociation particularly when there is alot of visual stimulus. It makes me feel quite weird when driving or playing sport. I have noticed subtle changes in my memory and learning ability.
495035 tn?1221753092 Have had two MRI brain scan done in two days and cervical. Demylination is what the neuro wrote and primary T ?whatever primary T? is any ideas anyone? I haven't got the results yet will take a few days.Still have the headache worse in the mornings and earache in both ears, last couple of days have had 'buzzing forehead inside' when i move my head i really dont know what that is ,does anyone else get it? it only lasts for few seconds at a time.
1421029 tn?1282717378 My LLMD ordered a SPECT scan instead of an MRI. A SPECT scan looks for how the blood is or is not flowing to and through the brain, and having areas of low blood flow may be consistent with Lyme inflammation and infection. I recall that my SPECT scan was pretty impressive -- as in, I was very ill and it showed up on the test. The problem is (as I understand it) that nonLLMDs don't often think of using a SPECT scan, because the nonLLMDs are looking for problems other than Lyme.
Avatar f tn keft foot dropsy, muscle pain and leg weakness, and the most awful vertigo...The nerologist did anoher MRI and again no lesions....Anser Use this MRI as a base line and wait and see for another six months...(Same answer I have had for last almost five years). I have seen several different neurologists(husband was in militarysaw military doctors until two years). Now I am seeing another nerurologist that is not military. I am going to keep on going as everyone says....

This is a never ending comedown. THROBBING in my head wont stop... I feel different... not the same. I'm sweating lots and not sure if that the heat or me.... help me someone.... how can I get better? Do I need amino acids or sumthin???
Avatar n tn They can however, detect mental illness such as scitzophreneia which i know because i was diagnosed through an MRI. The only mental illness an MRI scan able detect is an actually different brain connections than that of a normal brain. Ive had one done for mental illess! Can you describe some of your symptoms, what you feel and how often yolou feel it? I know your question is based on needing to know where to get a private MRI scan, which i am unsure of!!
Avatar f tn The ER doctors are the ones ordering all the scans when I get taken in for severe abdominal pain. I've asked for ultrasound or MRI & am always told they either won't work for what they're looking for or the MRI techs don't work after hours or on weekends.
Avatar m tn Is it normal to have that much bowel gas that the abdominal aorta cannot be seen. I still have pains in my abdomen. Should I ask for a MRI or CT scan to further investigate my pain? I also had a Hida Scan of my gallbladder with the results being 90% ejection fraction rate at 30 minutes, and I am 43 years old. Thanks in advance...
Avatar m tn If this Impedance Audiogram is abnormal, then a trial of medication should be taken for three to four weeks. If this does not work, a myringotomy with a grommet insertion may help. Steroid drops can be given for a longer duration through this ventilation tube. A MRI Scan is usually advised in a patient of vertigo so as not to miss any major cause, one of which is an Acoustic Neuroma. I must emphasize that Acoustic Neuromas are rare and almost 99% of MRIs are normal.
Avatar m tn Yes, an MRI can produce images radio waves and unlike conventional x-ray examinations and computed tomography (CT) scans, MRI does not depend on ionizing radiation. It seems, generally, the differentiation of abnormal tissue from normal tissue is often better with MRI then x-ray, CT and echo. But the state-of-art CT scan, slice 64 and higher has reduced radiation. Hope this helps.
Avatar f tn t know why they have it sounds a bit weird. He does sound a bit slack. If I was in your situation I would definitely have another MRI in the future. It will enable you to keep any eye on things. If you have a good relationship with your PCP then that's a great idea to chat with her about this. Take care Karry.
