Avatar m tn Hello, I have been experiencing significant chest pain and other various symptoms for the past year and a half, I am scheduled to get a CT scan of my chest this week but am concerned about the radiation. Do you know if an MRI can provide the same graphics? Your answer would be greatly appreciated.
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.
Avatar n tn When having a Hida scan, Do you lay in a machine such as the one of an MRI or what?
Avatar m tn The vice versa is true for MRI. MRI can produce images in any plane but CT scan cannot. CT scan uses X-ray imaging whereas MRI uses radio waves and magnets. Radiation exposure is moderate in CT scan and there is no radiation exposure in MRI. Hope this helps. Please let me know if there is any thing else. Take care!
Avatar m tn The reason I asked is that they don’t typically require follow up imaging for HCV treatment unless the patient relapses, or if late stage disease is present; in that case, ongoing monitoring for HCC (liver cancer) is often recommended. I’d go with the scan, as JD suggested; the benefits generally outweigh any risks.
968809 tn?1288656910 For anyone that has had a PV ablation, did your doctor schedule at CT Scan or an MRI of your heart before the procedure? I was told I would have to get a CT Scan. I'm very concerned about the radiation and was wondering if anyone had an MRI instead.
7510956 tn?1411671417 ordered a Ct scan with contrast for my liver since 6 months ago there was a lesion that was too small to determine what it really was. Is the Ct scan better than MRI ? I was thinking about the radiation of the CT scan and how bad it could be for the liver long term, since the MRI has no radiation I would think it would be better.Suggestions?
Avatar n tn As for the radiation, yes, there is some exposure from a CT - 1 scan gives you the same amount of radiation you would naturally be exposed to in the course of 3 years from the environment. Obviously your doctor feels though, that the benefit's outweigh the risks. I've had probably close to 25+ scans in just under 3 years, so it can't be that bad! An MRI does not give off any radiation as it takes pictures from aligning magnets.
Avatar n tn As doctors advise on taking CT Scan and MRI repeatedly for a children of 6 years old during diagonosis process, would there be any side effects to a child undergoing such exposures?
Avatar f tn Hello. I'm a 33-year old man, usually healthy. Due to a stomach ache and mild heartburn a few months ago, I went through gastroscopy in which a mild inflammation of the stomach was diagnosed. In addition, the doctor observed that the stomach was large and twisted, and it was difficult for him to push the endoscope further down the stomach. The doctor suspected a Volvulus and/or Paraesophageal hernia, and sent me to a CT scan of the stomach. My question is: is MRI also possible in this case?
Avatar m tn Radiation Risk for CT scan: CT emits a powerful does of radiation, in some cases equivalent to about 200 chest x-rays, or the amount most people would be exposed to from natural sources over 7 years. That dose can alter the makeup of human tissue and create free radicals, molecules that can wreak havoc on human cells. Your body can often repair that damage--but not always. And When it doesn't, the damage can lead to cancer.
Avatar n tn I would definitely ask for an ultrasound, blood enzyme test, then MRI if these two tests are inconclusive, a hyda scan and last would be a CT scan. Good Luck I was in your shoes once.
Avatar n tn I have seen the doctor multiple times but after the last particularlly bad migraine, she suggested I have a CT scan done just to make sure that everything is ok. However, I have read that the dose of radiation you are exposed to during a CT scan is huge and that concerns me. Should I have the CT scan done or should I request an MRI instead?
443136 tn?1210536325 When I was a baby, probably about a year old, I had a CT scan, or an x-ray (can't remember which one) of my head. Then, last year, I had a CT scan done of my head again on 5/31/07. They found a 2 ml lipoma (fatty tissue). They didn't think much of it, so on 6/18/07, I had an MRI done on my head. I know MRI's don't use radiation or anything, but still. Anyway, if you read some of my other questions, you'll see my list of symptoms I've been having.
Avatar f tn I am 43 year old female with bad pain on right side under my ribs, alot of burping!!!! I have been scheduled for a HIDA scan on Nov. 12th. I am very nervous about everything but the thought of radioactive meds. injected into my body really bothers me. I have tried to find info but it's not very helpful. If anyone has been through this can yu tell me if there were any side affects to the radiation? Alos my mother has Graves diesease so I am concerned this could hurt my thyroid.
Avatar f tn I can understand your confusion. Both MRI and CT scan can be used to screen for an aneurysm/dilatation. MRI is a safer option as it does not expose a patient to radiation, but the quality of image is poor as compared to CT scan (which exposes a patient to radiation). In case of doubt, CT scan imaging is done. So, yes, it is possible that a MRI is unable to catch a small aneurysm or gives a false image of an aneurysm/dilatation.
Avatar m tn t work I would likely do the bone scan. I prefer mri over bone scan because of the radiation and I have already had an abdominal ct last year which has huge amount of radiation.
Avatar n tn At times this bleed starts a week after injury causing symptoms and the need for a MRI. If the child is symptomatic consult a neurosurgeon and maybe MRI will be a better option with less radiation exposure.Take care!
Avatar f tn I'm having my second surgery tomorrow--it's a small re-excision because they didn't get a clear enough margin of the biopsy cavity on the first surgery (rats!) I'm also having the Contura (catheter) placed during the surgery. Then I'm supposed to go directly to the radiation facility to have a CAT scan, to see if the device is placed correctly, and than go twice a day for 5 days for radiation. My question is: have long does the CAT scan take?
Avatar m tn I can tell you that I have seen PET scans be too sensitive and over-read findings. The fact that your father had an MRI scan of the areas that 'lit up' on PET scan makes me suspect that the findings on PET scan were artifactual. I encourage you to discuss your concerns further with your father's doctors. I hope this helps.
Avatar f tn ve had the baby i need a scan but doctors refused to do it because of all the radiation. Im very surprised they are allowing it, but then im not a doctor.
Avatar f tn its been some time from the last talk we had, i had a cat scan done, doc didnt want an mri till one year after radiation, the cat scan showed a partly calcified avm, my neur doc, said that was a good sign, only thing i have now is everyday headaches and still head pains,plus not to mention the heartneat sounds I get in my eras, its been 8 months from radiation,am I in the clearn from side effects of the treatment?
Avatar f tn An ultrasound is a good idea and much easier to get then an MRI. Plus has very little radiation. Things in your body can change very quickly so don't rely on old tests to give current results. Keep me posted!
Avatar f tn If you are concerned about radiation, an MRI is an alternative procedure without the radiation.
Avatar n tn I’m 53 years old with aortic insufficiency and miral valve prolasp and I’m reluctant to have a CT Scan if there are alternatives. Would a Cardio MRI be at least as effective as a CT scan to help diagnose the following: Aortic valve condition, such as is it bicuspid, calcified, stenosis, and the extent of insufficiency? Aorta condition? Heart mussel mass? General cardiovascular condition (blockages)? Condition of the Mirtal valve?
Avatar f tn ve had a bone scan, MRI, and a CT. Everything looks good. I had radiation weekly with carboplatin(sp) for 8 weeks and cisplatin and taxol for 12 weeks. My last treatment was a year ago, Feb. 14th. I had 3rd stage endometrial cancer. I'm 57 years old and hope to get on with my life. Do I need a higher dose of vitamin D than the daily requirement?
