Cat Scan Vs X Ray
Normal cat scan, x-ray, and ultrasound - pain in right lower lung or upper abdoman still in pain, what's wrong? (right side)
I was having cough for three weeks so advised chest X-ray , which showed cyst in diaphragm. Further i got cat scan but it was clean. What should I do.
What does Doc say?: Please discuss this with your physician. There may have been a lucent area near your diaphragm, sometimes called a lung cyst, bleb or bulla. Without the x-ray it is hard to know. If definitely benign or stable when compared to an old x-ray, further workup may not be necessary. However, if there are any symptoms or concerns, chest ct is more sensitive, specific and accurate than chest x-ray. ...Read moreSee 1 more doctor answer
Numbness, tingling and spasms to right side of face. Had 3 seizures cat scan, X-ray and MRI clear what is the cause? (been put on keppra (levetiracetam) for seizures)
Have the MRI checked: If yuor MRI was not read by a neuroradiologist or done on a high field MRI machine it might need to be repeated. Usually the test should be done with and without an injection of safe gadolinium based contrast. If your doctor is happy with the quality of the test then you might need to see a neurologist as well if you have not already. ...Read more
Too much radiation? Recently, i had a cat scan of my sinuses and a chest x-ray.
They are thinking about getting a cat scan of my brain. But to my understanding that's a lot of radiation in a short amount of time. How long are you supposed to wait until th
The : The amount of radiation from ct is certainly higher than from traditional plain film xrays, and you're right to wonder about the risk. However, there are a couple of important issues to consider. First of all, if there's a clinical problem that needs to be sorted out, and if ct is the best way to do that, then the amount of radiation from one additional study is probably not worth worrying about: you're far better off getting a diagnosis that leads to treatment than missing that diagnosis because the full evaluation was not completed. Secondly, you should know that the risk of radiation from cts (and other sources) have to be looked at in both short term and long term perspectives. Without getting too involved in physics, the message is this: a lot of xrays in a short period of time can cause short-term injuries like skin burns and hair loss, whereas a large number of xrays over a lifetime may increase the risk of cancer. It's very unlikely that another ct scan (or even several) right now would cause a skin injury--that's much more likely with image-guided procedures like coronary angiography. On the other hand, your risk of developing cancer from ct imaging (though very small) is the same whether the cts are done all at once or spread out over several years. What it boils down to is this: if your doctor has a specific concern and needs more imaging to make a diagnosis, then getting another ct is probably a good idea. Waiting a while won't make any real difference, except perhaps to delay your treatment. If, on the other hand, he or she is just "covering the bases, " then it may not be worthwhile. You might ask your doctor what, specifically, he or she is looking for and why he or she can't use other tests. ...Read moreSee 2 more doctor answers
Can you explain results of chest X-ray led 2 cat scan, which led 2 pet scan. results are multiple nodules. what causes lung nodules?
Multiple: There are many causes for pulmonary nodules, which can be broken down into benign or malignant. There are a large number of causes for benign nodules, and 95% of nodules seen on CT scan are benign. If the nodule is large enough, a biopsy may be recommended. The initial move is to see if the same mass was present on a previous scan. PET scans are used to add information, but should not be done firs ...Read more
Night sweats , shortness of breath , chest pain , hot flashes , can this be Tb? Pleuritis ? Costochondritis ? Had a cat scan and X-ray nothing showed
See Doctor: Pleuritis at your age is rare. Costochondritis is a possible and common cause of chest pain in young people but it does not explain the hot flashes, night sweats and shortness of breath. TB is very rare in this country but if you have been exposed you may want to make sure you're in the clear. You may want to see your primary care physician for a workup. ...Read more
Had 2 chest x-rays. Both showed a bulky helium. Could you tell me what this could mean. I am waiting for an appointment for a cat scan.
Enlarged hilum: An enlarged hilum seen on chest xray could be due to enlarged of abnormal lymph nodes(tb, malignancy) or enlarged structures such as an artery. Many times, however, the chest ct scan shows there is no significant abnormality when the chest film suggests an abnormally prominent hilum. ...Read more
Probably not: Although all radiation is cumulative, diagnostic x-rays fall well within the safe level. If x-rays or cat scans are diagnostically necessary, the chance of damage from not being able to visualize the problem is much greater than the chance of damage from the necessary diagnostic modalities. ...Read moreSee 1 more doctor answer
I've had a vcug, cat scan and chest/back/spine x-rays. Can the radiation from tests cause cancer?
I am have sharp pains on my right side around my hip bone especially during sex or any kind of work I have had cat scan and x rays done but no results
I’ve had 2 cat scans of the abdomen possibly 3 CT scans I can’t remember .3 X-rays plus dental X-rays and mammograms since age 40. nervous about Radiation. How much is too much? When will cancer develop? This is all within the last 20 years. Scared!
Radiation Exposure: The dosages that are used for diagnostic imaging are very low and should have no long term effects on your health. With modern sensors or film, the dosage administered is considerably less than years past and lead shielding limits the exposure to the areas needing imaging. Better chance that you will benefit from a proper diagnosis than be harmed by the diagnostic radiation. ...Read more
7 months of bladder infections. Taken k flex, amoxicillin, penicillin, bactrim, (sulfamethoxazole and trimethoprim) now on Macrobid for 17 days CAT scan x rays ultrasound normal help?
Too many; c a Urolog: At your age, I think that's too many bladder infections. Something underlies these recurrent infections: something that antibiotics alone can't fix. While the CT scan & imaging test show that u (or some1) is concerned, they r the wrong tests. What u need is a cystoscopy by a Urologist (looking @bladder with a scope). If it's neg, a voiding cystourethrogram (VCUG) wd be the type of CT scan to get. ...Read more
Unclear: There are multiple variables in determining the risk to fetus. The risk depends on the age of the fetus. The fetus is most suspective to damage in the first trimester. X-rays and ct exams taken far away from the wombs such as the head or extremities actually provide little to no radiation to the fetus. It is common procedure to cover the womb with lead if there is any chance of pregnancy. ...Read moreSee 1 more doctor answer
