Radiation Exposure From Radiography Bone Survey
Yes: Both x-ray an isotope for bone scan produce ionizing irradiation. Exposure from isotope of bone scan in adult is about 6 msv. This is similar to some ct scans.The only imaging methods not involving irradiation are ultrasound and magnetic resonance imaging mri. Information from each test is not the same. ...Read more
Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more
Radiation exposure in facial bones cbct?Dr suggests cbct, but i've already got xr, ct+3xcbct to head in last 3 yrs.I'm concerned about cumulative dose.
CBCT Concerns: I would have the dr evaluate those other images you have had done and see if they could be of use today! if there is any consolation, the digital images today expose you to a third or less of the previous radiation exposure! ...Read more
If the effects of dental x ray radiation exposure is cumulative, does that mean all the x Rays damage I ever gotten stays there?
Yes: But as with any medicine it's risk vrs. benefit. A full set of diagnostic dental x-Rays is less radiation than spending a day in the sun. The health care community is very careful about the exposure you receive, taking only those films or digital films required to aid in your treatment. ...Read more
Think about it...: If riding in an airplane were a risk, what would the pilots and crew face? I am a 2m miler and while the exposure is more than if i lived in cave, i would never have seen the taj majal or foz do iguazu. Slight increase in risk; versus astounding benefit. Same can be said for x-ray exposure. Get only x-ray tests needed. ...Read more
Radiologist: a fluoroscopy for epidural spinal injections for back pain (l5-s1). It's about the same radiation exposure for me as one chest X-ray ?
Not Exactly True: Depends on how long the procedure takes. Typically most epidural injections take about 15-20 sec of fluoroscopy time, that is in order of 10x less than typical chest x-ray. Now if injection takes longer than one minute (60 sec) of fluoroscopy time than you will be close for exposure. That's a lot of flouro for this injection! ...Read more
Any you don't need: Radiation exposure is guided by the principle of ALARA- As Low As Reasonably Achievable. So, any imaging or treatment involving radiation exposure should be considered in light of risk:benfit ratios. If you don't need a scan, don't have a scan. Same goes for treatment, but with that said radiation is a very useful tool in the management of a number of conditions. ...Read more
CT scans: If there is an alternative to imaging the area such as MRI, then we prefer MRIs. There are some studies looking for bony problems that CT scan works better than MRI. Also in some settings, such as an emergency, if CT can be obtained more quickly or MRI not available, then CT is the test. How badly do you need the images and how soon are parts of the equation. ...Read more
The first: Issue would be potential source of exposure. There is natural background exposure, medical exposure and inadvertant exposure. Total bidy radiation causes symptoms depending on dose. The most lethal is CNS syndrome -seizures, GI - massive emesis, diarrhea, then bone marrow, causing aplastic anemia. ...Read more
EP study: The radiation exposure depends on the MAs used by the flouroscopy and the time of exposure. The exposure will vary by length of time the flouro is on and this isn't uniform for each study. Ask your EP doc for his likely exposure estimate. ...Read more
Depends how much...: Radiation is naturally present in our environment. With low levels of radiation exposure, the biological effects are so small they may not be detected.The body has repair mechanisms against radiation-induced damage.Any amount of radiation may have some risk of causing cancer, and that the risk is higher for higher radiation exposures. High doses can cause tissue and organ damage.Hope that helps! ...Read more
How close must you be to someone with radiated pellets implanted in his body, for you to have radiation exposure?
Radiation pellets: Very very localized therapy, not significant for those around the patient generally speaking. ...Read more
Here's for starters: In atom bomb survivors, all the common leukemias except chronic lymphocytic leukemia ended up being increased. Breast and salivary gland cancer also had some increase. Following therapeutic radiation, there's more of a risk of sarcomas since unlike chemicals, radiation doesn't spare their cells of origin. Lately increased colorectal cancer's been shown after prostate radiation. Hope this helps. ...Read more
Yes: But small amount from cosmic radiation, with in the safe limits. ...Read more
If a significant radiation exposure has potentially occurred, you need to see a physician as soon as possible. The most likely course would be to go the ER and have them consult a radiation oncologist and medical oncologist. A radiation safety officer can also be consulted by the physicians. Dose estimates need to be made to determine if acute care is needed. Hope this helps. ...Read more
In the early: days of radiology, little was known about the long term effects of radiation, and many xray workers and doctors ended up with cancers. Nowadays, exposure is minimized by safety equipment and improved technology. Radiologist xray exposure is monitored on a regular basis with badges and other detectors. ...Read more
Do you think steve jobs cancer was due to any inadvertant exposure to radiation or computer chemicals?
Do not discuss other: Hipaa and etiquette prevent discussion of other peoples lives whether they are celebrities or otherwise. Could you ask the question in a different form. ...Read more
I've heard that taking iodine tablets can help with radiation exposure during long flights, is this true?
No: The amount of radiation reaching the us is far below toxic levels. ...Read more
Which professions have the highest occupational exposure to radiation, and does it prove itself in cancer cases?
What do patients think of radiation exposure in medicine, for diagnostics and treatment? Do patients get scared?
No if informed: If patients are informed properly , they will not 'get scared'. First the amount of radiation exposure in diagnostic test is negligible you get more by going to beach. During treatment precise , focused dose will be given with out damage to surrounding tissue, equipment also getting advanced. ...Read more
For the last 6 months, we were sleeping with an ionizing radiation smoke detector
Above our bed.Did we get a big amount of radiation exposure?
No,: it is probably an unmeasurably miniscule amount far below background levels. ...Read more
Should xray tech require patient to wear protective shield during a neck xray, because mine did not just wondering if shield is required because i worry about exposure to radiation
Fatigue: Would be most common, diarrhea (sometimes bloody), and weight loss can all be signs of acute exposure to high levels of radiation. Not a big problem unless world war iii starts... ...Read more
