Avatar f tn can anyone help explain what my MRI/MRA scan results mean:While no definitive aneurysmal dilatation of the intracranial vasculature is evident, there is subtle suggestion of potential fenestration of the M1 segments bilaterally, left slightly more conspicuous than the right. There is no evident hemodynamically significant stenosis or high flow vascular malformation. The dural venous sinuses demonstrate normal flow-voids.
Avatar f tn Any way to tell? I have a cd with the MRI pictures on it at home. The CT scan was high resolution because they were looking for a problem with my superior semicircular canal, but that scan indicated the superior semicircular canal seems to be just fine.

Avatar m tn I had a MRI from the hospital and got a CD, which has a viewer and images. Dr. showed me the pancreatic tumors (about 15 cysts) on the computer screen. I tried it on my computer, but I could not see very clearly, I have two computer with the display resolution of 1440x900 and 1920x1080. Higher resolution showed better images, but still less quality than what I saw in the Dr's office. To see the better images, what do I need ? Better viewer software or better resolution display ?
Avatar m tn hi, From what I have learned on this website the higher the resolution MRI machine you can get access to the better. I believe 1.5T is like the minimum for good visualization and 3T is much better if you have access. They have a good article that is printed on this very subject if you go to the Health Pages section in the upper right hand corner of this site, that talks about this and lesions. I learned from this.
Avatar f tn I recently had a ct scan of the brain. The radiologist suggested a MRI follow-up. I have a pacemaker and cannot have an MRI. A neurologist is currently reviewing the films. What are the possible next steps?
Avatar f tn It sounds like they suspect inflammationn in the lung. You should request an MRI rather than a cat. The MRI is far less dangerous and shows up everything you might want to see. The CAT, which uses x-ray radiation, is an obsolete machine. The "snow storm" could be mucus or fluid, or remnants of an infection. Pain and shortness of breath are consistent with such a problem.
Avatar m tn I get a stinging pain on top of my head on right hand side about tree inches from my forhead. It feels like a blister under the skin. I have had an MRI scan and have a small Mengioma but that is on the other side. There was nothing to explain the stinging. I read elsewhere on this site that Clanzpine 2.5 ml should work for it but it didn't say what the complaint was. Any idea?
572651 tn?1530999357 One of the main things that thses studies tell us is that in the lower resolution MRI machines many lesions are still INVISIBLE. This is true even for the 3T (because the higher machine still shows more lesions). We need to remember this when our neurologist tell us that there is no such thing as an invisible lesion or when they say that "no lesions" means "no MS." So, for us, that software engineer is quite wrong.
Avatar f tn The alternative to MRI for those with metal in the body is CAT scan -- it uses xray instead of magnetic energy, and is also high-resolution (unlike straight xray).
667611 tn?1226005294 Yup, that's with and without contrast. I have the worst luck adding on MRIs to my scheduled MRI. I had a cervical MRI and thought - heck, I'll be there - just scan my head again. No go. The neuro thought it was 'too early' as I'd had an MRI six months prior. However, that's just my neuro. Feel free to ask yours and see if he'll throw another one in there.
5531927 tn?1445274919 Hello, I'm current waiting for a CT scan appointment as my MRI isn't until 7 months from now to rule out a suspected acoustic neuroma. I saw an ENT who confirmed high frequency hearing loss in my left ear. My symptoms have changed from just fullness in that ear to frequent headaches, very mild tinnitus, one pupil is bigger than the other, and I can hear my eyes move when the room is quiet. That last one doesn't appear to be a normal acoustic neuroma symptom.
Avatar n tn A CT scan alone may not determine ALS. It is difficult to diagnose with simply one test.
Avatar f tn ” If the chest CT scan does not provide a diagnosis, bronchoscopy may be helpful Diagnostic testing for the cause of your dizziness (with eye movement and/or turning your neck)) should proceed concurrently with the above. An MRI scan of what are called the vestibular areas might allow for clarification of the cause of these symptoms.
Avatar f tn The CT scan is useful for imaging the tissue behind the bone or far from surface. If tumor is questionable MRI has much better resolution (CT scan can sometimes produce artifacts) Not to mention radiation exposure = to 6 chest x-rays. If tumor moves during swallowing it is somehow attached to thyroid capsule or voice box.
Avatar f tn MRI, Cat scan. digital scans, high resolution scans all the stuff does not guarantee that an infection will be shown up . Many time the infection has to reaches a certain point or it is hidden. My friend was very sick for three years had body scan, MRI you name it she had it She even flew out of the country to find help She came home found a doctor to open her up and look inside, the thought her appendix looked bad.
Avatar n tn I went to my family Dr and he ordered a CT scan and a MRI. I did my CT scan on Saturday and the Dr called to say that there is bruising on my brain but it is not near the pain at the base of my skull. My MRI is scheduled for next week and the Dr said they will now do a more in depth MRI after finding the bruising. What is your thougts on what is causing my headaches and are they related to the bruising? Why would I have bruising now with no recent head trama?
Avatar n tn For optimal imaging of the subarachnoid space and nerve roots a T2 weighted, high resolution scan is necessary. Axial views (cross-sections) at the suspected spinal level are important to demonstrate clumping of the nerve roots, and/or their attachment to the dural wall. The nerve roots that are affected clinically should be present in the same location as the arachnoiditis seen in MRI for a confident diagnosis.

Avatar m tn I have seen my PCP and I have had a CT scan done. I have tried the MRI machine but even with a valium I cannot complete the test because I am very claustrophobic. I have not been having any headaches or any upset stomach or vomiting. My balance and memory are fine. Im not on any medication. I am 33 year old overweight male. I have had all bloodwork and diabetes test performed and come back normal. I just completed a heart echo and carotid artery test and came out normal as well.
Avatar m tn I had a second opinion report that asked to exclude lacunar stroke and suggested MRA scan and MRI scans with contrast. I saw a neurosurgeon who identified the mrs finding as a porencephalic cyst probably due to trauma. i then received a report from a neurologist who said it was a virchow robin space. the size of the lesion is 1.2 x 1.3 cm which is large for a virchow robin space. it is situated near the basal ganglia on the right side.
Avatar m tn To confirm that this is the case, you need to get an MRI scan of your cervical (neck) spine. X-rays or CAT scans do not have the resolution to typically see the herniation(s). I recommend either getting your PCP to refer you to a spine orthopedic specialist or physiatrist and they will order the MRI scan. Physical therapy, epidural injections, and medications have shown efficacy at treating cervical radiculopathy.
Avatar m tn I have tried all sorts of cushion. I think this pain is caused by a nerve somewhere. Im having an MRI scan next week. Nerve root inflammation has been suggested. Im trying acupuncture, and its possible this is beginning to have a slight effect, in that the duration I can sit has increased a few minutes. This new pain is baffling, as I cannot think of anything that would have brought it on.
Avatar m tn Hey guys, I'm a 22 yo male never smoker. I have no family history of any cancer or lung disease. I do have GERD/acid reflux, which I've had for about 3 years. ------------------- History: My very first symptom, about 2 months ago (October) was some "hardened" lymph nodes in the left supraclavicular region and in the lower rear of my neck on the left side -- this is what sent me hurrying to doctors to figure out what's going on.
