Cat Scan Vs Xray
Do i need to worry about sca with a normal cardiac workup( ekg, echo, stress, chest xray and CT scan)? Blood work overall normal, scared/high anxiety?!
Probably not: A sudden cardiac arrest (sca) is a rare phenomenon. It almost always occurs in patients who have cardiac disease: either electrical, mechanical, or related to a heart attack. It sounds as though all of your testing has been normal. This should provide some relief from your anxiety. ...Read moreSee 1 more doctor answer
Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
Feel sitting on my croccyx since 14days, from cat scan &xray its fractured.when could I normally sit, drive & normally bent my back plz?
Tincture of time: Fractures in any part of the body take time to heal up. The same could be expected from a coccyx fracture. My best advice would be to get a donut cushion, and lumbar support which should definitely help with your symptoms. We are talking about at least 3-4 month before fx heals up completely. Consider tylenol (acetaminophen) for pain. Also, if post menopausal consider bone density scan to r/o osteoporosis. ...Read more
In december he had a chest xray for at that time, a single nodule observed. Cat scan now shows 2 benign nodules w/ 1 inflamed. What next?
Discuss with doctor: Discuss the situation with your doctor. What to do next depends on the actual images on the ct and the opinion of the radiologist (a doctor specializing in image interpretation). Your doctor may need to talk to the rad. Sometimes the ct can clearly determine if the nodule is benign, but sometimes followup ct's are required. If there is an old ct to compare with, that would be extremely helpful. ...Read more
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
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
Cramping sharp pain in chest when i move a certain way or bend, sometimes out of nowhere, pain level 10 dont last long normal xray EKG and cat scan?
Chest pain: Usually when you have pain that hurts when you move it is your muscles or bones in the chest wall that are causing the pain. However, there are many factors to consider about the best workup and how urgent you need the evaluation such as how long have you had it, how old you are and what other medical problems you have. If you are short of breath at all you should immediately seek medical care. ...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
Adominal pain like contractions for a month had xray cat scan no answers not ibs,kidney stones, bladder, or appedendix. Any suggestions ?
Work with one Doc.: It is important you see one physician when trying to find the cause of abdominal pain. When the cause of your pain is not apparent on a CTscan and/or x-rays, you may need further testing such as an ultra sound and blood tests to check for things like gall stones, ulcers and gluten sensitivity. If that does not provide the answer, you may need a referral to a GI specialist for possible endoscopy. ...Read moreSee 1 more doctor answer
I had nothing on knee mri, but a loose fragment shoes on xray. Now doctor wants cat scan. Is this necessary prior to arthroscopy and why?
See below: Xray and MRI are very different. A loose body seen on xray may not be visible on MRI if it's small and calcified and the radiologist reading the MRI did get to see the xray. It's also possible that the "loose body" on xray may not be an actual finding. Ct is recommended in this case probably to reconcile the differences as ct can see calcified loose body and the joint spaces fairly well. ...Read moreSee 1 more doctor answer
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

Heart failure. : Heart failure usually occurs slowly but can be precipitous. Understanding what the etiology causing the failure helps to understand best routes to evaluate and teat it. Your heart failure could be easily missed especially at your age. Talk to your doctors to understand what happened in your case. Physicians practice to help patients and to ensure they understand what is going on. ...Read moreSee 1 more doctor answer
I just had an angio pulmonary cat scan with contrast to rule out a pulmonary embolism. Can that detect lung cancer? Chest xray normal. 42 years old.
Yes,: that type of CT can detect lung cancer. Tiny nodules 2mm or less can potentially be detected. There are benign causes for nodules as well, so although CT is good at finding nodules, and possibly assigning a reasonable probability of malignancy based on certain imaging features, CT cannot make a definitive diagnosis of cancer. ...Read moreSee 3 more doctor answers
