mr angiography of brain

Hi, My close relative (uncle - 63 yrs old) had recently undergone collar-bone plate-removal operation, during which time, something happened because of which the supply of oxygen to brain stopped all of a sudden and he became unresponsive and has been in unconscious state since then (more than 3 weeks now). He was in ventilator for 12 days and has been in ICU since then. Rest of the body is functioning in a normal manner.

No previous MR for comparison. No midline abnormalities except signal changes within the corpus callosum. A craniocervical junction is difficult to assess due to lack of T1 sagittal weighted images. Posterior fossa is not enlarged. The craniocervical junction is not well demonstrated. Aqueduct is patent. There is some prominence of the occipital horn of left lateral ventrical which may represent normal anatomical variation.

If the doctors think there might be any vascular problem, you may go for the MR angiography. But that only depends on your symptoms. If you have had neuropathic symptoms, you will probably need EMG.

Magnetic resonance spectroscopy (MRS) is different from MRI because MRS uses a continuous band of radio wave frequencies to excite hydrogen atoms in a variety of chemical compounds other than water. These compounds absorb and emit radio energy at characteristic frequencies, or spectra, which can be used to identify them. Generally, a color image is created by assigning a color to each distinctive spectral emission. This comprises the "spectroscopy" part of MRS.

Well, I'm home from having had my CT Angiography of the brain and heart. Now, I just have to wait one week until I go back to the neuro to find out the results of it. The Neuro said my last MRI was the weirdest and unusual MRI of the brain that she had ever seen. The report said something about Vertebral Basilar Insufficiency and something about an enlarged vessel or something. My brainstem has moderate damage (Chronic Gliosis) and it didn't sound like it was damaged from the MS.

MRA differs from MRI. They both rely on magnetic resonance, but MRI images nonvascular tissues and contrasts them well from one another. MRA is specific to examining the vasculature (blood vessels; angio = vessels). They usually use a contrast dye to trace blood flow (or its absence) through the arteries in different tissues, although there are some fancier MR methods of imaging the vasculature (like TOF, which stands for "time of flight").

Her genral codition is now stable and doctor has now advice for angiography, kindly suggest whether we should go for angiography and depending upon result of it we should go for further process ( such as angioplasty and ByPass ) as my grand mother age is 78. Please suggest.

Hi, CT (computerized tomography) scan of the head will show a subarachnoid hemorrhage in more than 90% of cases of ruptured aneurysm. In the few cases that are not recognized by CT, the healthcare provider may consider performing a lumbar puncture (LP, or spinal tap) to identify blood in the cerebrospinal fluid that runs in the subarachnoid space. If the CT or the LP reveals the presence of blood, angiography is performed to identify where the aneurysm is located and to plan treatment.

MRI of the brain was performed without and with intravenous gadolinium contrast. MR angiography using 3D time of flight without gadolinium contrast was also performed with multi-planar and 3D reconstructed images.

Also, dilated Left Ventricle can also be the result of high blood pressure. Also, the filling of blood phase is impaired due to wall stiffness. That can also be related to high blood pressure. Jerky septum. Septum is the wall that separates the right and left side of the heart. Along the septum are electrical pathways for impulses to pass into the ventricles to cause contractions.

I am diagnosed with two small aneurysms 2mm on left median artery vertebralis and approximately 4mm one on the basilar artery directed towards left I had just headache which doctors say can not be due to aneurysms and I was diagnosed by chance on MR angiography.

Is it classed as heaet failure? Non smoker...Burning (brain, spine and heart) knotting, pulling, uncomfort, lack of breath, air hunger....list goes on.

hi :) I have a sharp pain shoot through the right side of my brain, it comes on randomnly but every time I smoke I get it. It's only recently started up after an hour nosebleed that I had, any ideas on what's up?

Dear Mam, Thank you very much for the reply. According with Nerologist suggestion we undergone a MRI scan & MR Angiography of Brain. The main observations after MRI scans are 'Area of restricted diffusion appearing dark on ADC' seen in right superior cerebellum. Other tiny restricted diffusion appearing dark on ADC in right hemi mid brain & hemi pontine region. The Impressions are 1).

5,Tab repace,Flavedon MR 25.As of now my father is stable he is showing good signs of recovery but one question always haunts me since he is a stroke patient and also he is suffering heart problem what would be his future i mean how long can he sustain life, every day when i get up i wish everything is ok with him.

Can you please tell me what type(s) of machinery/techniques should be used to determine the rate of blood flow in the brain and brain stem? Does looking at a picture (such as a MRA) and seeing a blood-filled Circle of Willis suffice? Thank you for your time!
