I am having a CT scan on my brain on Weds..I am so scared?
A ct is a painless exam where you lay on a bed, and the bed moves into the scanner. There is something inside that is spinning around and it is taking pictures of your head/brain. They may also use contrast, which helps them differentiate the structures in your brain. I have had one, and an MRI as well, so I know how you feel. Most of the time they don't find anything, so keep that in mind. Both CT and MRI's are good studies, and you may need both. An MRI is a little more complex, and takes a bit longer. For mine, you lay on a table and they slide your head into this cage like contraption, and lock it to the table, which is a little freaky, but I think it is for marking and identifying exactly where they are at during the study. You have to hold perfectly still, or it makes the images blurry. It takes about 30-45 minutes for the MRI, where the CT only takes a few minutes, unless they use contrast, and they do it twice, once without contract then again with contrast, to compare any irregularities. The contrast is interesting in and of itself. The tech told me I might feel like something heavy was on my chest, a metal taste in my mouth, and the feeling of wetting myself, but that most people don't. I guess I am lucky, I felt them all, and it really does feel like you wet your pants for about 5-10 seconds. I wish you luck, try not to lose too much sleep over it, I am sure everything will turn out alright. You can also search about info on the two different studies.
Why do you need to take out jewelry in a ct scan/x ray?
I had a xray of my nose....and i couldnt take out my industrial(bar in the cartledge of the ear).they said it would show up on the picture..it did. and another time when i had a head ct scan done i asked if i needed to take out my nose stud and he said no its alright... my question is, if its dangerous to my body if i left them in? or do they just say take it out so it doesn't affect the pictures only? i also had a cervical spine MRI which i had to take out ALL my jewelry even my bra! why is that so much different? thankyou
I wore a belly ring during a CT Scan?
I've been sore since my CT scan of the abdomen yesterday and in looking for side effects of the dye I've been reading you shouldn't have any metal. My technician didnt say anything about it he just moved my shirt up because of the buttons but I was wearing a surgical steal ball belly ring. Why is that bad?
What are some features that help distinguish a picture of a CT scan from a picture of an MRI scan?
CT scans differ quite a lot from MRI scans.CT (Computed Tomography)The CT's main principal is based on X-rays passing through a body, being weakened by tissue. The weakening (or attenuation) differs per tissue, as dense tissues absorb more X-rays than less dense tissues. Also CT uses a specific measure to quantify the density of tissues, expressed in ''Hounsfield's units'' (HUs). Tissues with more HUs are denser than tissues with less HUs. CT scans are often used when a physician needs a quick diagnosis. In general CT's are used for bone related abnormalities and are great for imaging the circulatory system (using iodine contrasts).This is a CT image, notice that the fluid is black, this is due to the fact that X-rays pass easily through water.MRI (Magnetic Resonance Imaging)An MRI excites H protons in the tissue using Radio pulses. When the H protons are excited they gradually lose their energy (relaxation), this emits a weaker Radio pulse wich can be measured and quantified. Some tissues have longer relaxation times than other tissues, this creates the contrast in between different types of tissues.As earlier mentioned the visual representation of an MRI image is dependent of the type of ''sequence'' that is used. To understand how this image arises you must know how a sequence is built. The most basic sequence is a ''spin-echo'' sequence. It consists of a 90 degree excitation pulse (the vectors of the protons dephase) and 180 degree pulse wich rephases the protons (as shown in the .gif below).https://upload.wikimedia.org/wik...MRI is excellent in diagnosing central nervous system related diseases. In general an MRI examination is used to diagnose soft tissue related diseases (see images).Another big difference is duration of the examination, a general MRI examination usually takes about 20 minutes where as a general CT examination takes about 5 minutes.This is a T2 weighted MRI image, notice that the fluids in this image are bright where as tissue is relatively dark.this is a T1 weighted image, when you compare this image to a CT image it seems like there are hardly any differences. If you look closely though, you see more details in the soft tissue region of the image, something that is a lot harder to see on a CT image.I hope this answer was sufficient.
I have a clicking in my head?
You didn't say any pain with it, that's tmj out, you don't have to be a dr. to know a cat scan isn't going to show anything other than a big hold in your pocket for nothing. Do this and see if it goes away. Put both your hands behind your head and place your fingers on the muscles of your neck and pull into them with a moderate pressure and hold it. Then relax, take a big breath and let it out and don't tense up any part of your body, including your arms, let your hands do the work. After 30 seconds, slowly look up until your neck is fully extended Then release the pressure but hold your head there for one minute. Let me know if that helps. Otherwise I have some others to try to figure this out.
Bubble/ popping noises coming from my nasal cavity/nose?
I know it might sound crazy but its true. My doctor said shes never heard of such thing. I have always had sinus problems and bad headaches maybe its connected? Why am I having these popping bubble noise coming out from back there? What are they? Its usually when I am lying down i feel and hear it. Any answer is appreciated thanks!
Im scared i have a brain tumor.?
Well, to cut a lond story short, heres some symptoms i've been having: Headaches, Feeling sick, Waking up in the moring really aching mucsles, getting angry, neckpain, mucsles in my legs keep moving by themselves, my visions got worse. It sounds so bad. I went to the eyedoctor about my vision and he looked in the back of my eyes and did some tests and my right eye is worse than my left and he did some tests to check my brain and he said he couldnt fing anything in the back of the eye. My doctors think its tension and panic attacks and may be due to sinus problems. Im 14. Thanks.
A water like clear fluid runs down my nose when I bend down. Even sometimes when I sit idle, it happens mostly from my right nose. My right eye also gets wet, sometimes it hurts. I feel a disturbance on the right side of my head. What should I do?
I am a neurosurgeon and what you are describing could be a case of spontaneous CSF rhinorrhea. CSF means cerebrospinal fluid and it's the fluid which is giving nutrition and cushioning effect to your brain. And rhinorrhea means leaking from nose. This leaking usually is more on sneezing coughing or bending forwards....and there is a salty taste to it. This usually starts when there is some bony defect within the nose which let's the sterile CSF out through the nose.The feeling of dizziness and black outs can also be explained because if this as it can cause intracranial hypotension ( sorry for using medical terms). Intracranial hypotension occurs when the Cushioning effect of CSF is lost momentarily and the pressure the head decreases causing dizziness.You should get yourself evaluated by a neurosurgeon. As this leaking is not a normal thing and this increases the chance of infection spreading into the sterile csf and which has its own consequences ( details your doctor can provide).First he will ask you to collect that fluid in a sterile container and do some tests to make are that it's CSF and nothing else.And after that depending on the results, further imaging to find the cause will be done.This should not be taken lightly and visit your doctor as early as possible.Dont get scared or alarmed.All these are treatable conditions.As far as the question of memory impairment is concerned. There is no way this CSF leak can cause memory loss. There are no neurons lost ( it's absolutely absurd) and the memory region of the brain is in entirely different location.You can get your memory also evaluated by your neurosurgeon ( but I am pretty sure it's not needed).To repeat again....don't take this condition lightly.If you have1) Watery discharge coming thru nose with sneezing coughing bending forward etc2) If that fluid is salty to taste 3) If you are having some fever along with the leak4) If you have a history of injury to nose , head or were involved in some accident many years ago.If you have these symptoms.Go visit your doctor. it's essential.
