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 ?

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

Gamma Rays (Definition)

This is light of extremely short wavelengths typically produced either among the stars / in cosmic rays or by radioactive element decay. Gamma rays form the background of normal radiation in which we all live; it is substantially greater than the exposure we get from imaging scans or should get from ...Read more

Is the radiation from an X-ray dangerous?

Is the radiation from an X-ray dangerous?

The amount: of exposure for diagnostic x-rays is considered safe. Any increased exposure to radiation contributes to a cumulative theoretical lifetime risk, including flying on a plane, but the risk from a single x-ray is miniscule. That said, the increased risk is zero if you don't have the x-ray, which is why x-rays should only be utilized when medically necessary. ...Read more

Do I need to worry about radiation effects from an x-ray?

The theoretical: increased risk for any individual xray is minimal. For a medically indicated xray, the diagnostic benefit outweighs the minimal risk, so although it is always prudent to be aware of cumulative xray exposure, worrying excessively about X-rays could lead to imprudent and dangerous health care decisions. You can calculate the risks at xrayrisk.com. ...Read more

Could i be exposed to too much radiation while x-raying horses, wearing only lead glove to hold X-ray plate, for several years?

Could i be exposed to too much radiation while x-raying horses, wearing only lead glove to hold X-ray plate, for several years?

Depends on : Type of x-rays and how many, and where you were situated in relation to the x-ray beam during the tests. You should have been wearing lead apron, glasses, and thyroid protector. Also, you should have radiation exposure log, so ask your employer. ...Read more

Please tell me the difference between X-ray and fluoroscopy machine?

Please tell me the difference between X-ray and fluoroscopy machine?

Still Vs Movie: Both machines make imagews using x-rays. A fluoroscopy machine is designed to produce real-time images that can be view on a monitor. They also have the capability to acquire snapshots (spot images) during fluoro imaging. A regular x-ray unit produces still images like bone or chest x-rays. ...Read more

What can they do to reduce X-ray exposure to patients during fluoroscopy?

What  can they do to reduce X-ray exposure to patients during fluoroscopy?

Not much: Newer equipment will often have less radiation. "pulsed" fluoroscopy is used with children. Shielding with lead apron may be used. Your best protection is to avoid fluoroscopy or have an experienced radiologist. ...Read more

What is a significant thing radiographers can do to reduce X-ray exposure to patients during fluoroscopy?

Do it fast.: Using the least amount of fluoroscopy time is the most important factor. Collimating the x-ray beam to the smallest size required to cover the area of interest will reduce exposure further. Using fewer frames per second during digital fluoro is another factor as is using a higher voltage x-ray beam. ...Read more

Approximately how much radiation does a sinus X-ray expose you to?

About 0.1 mSv,: similar to a chest xray. To put that in perspective, natural background radiation exposure is about 3.1 mSv/yr. It is minimal. ...Read more

How do they protect your neck from radiation, when you get a neck x ray?

How do they protect your neck from radiation, when you get a neck x ray?

No: They can't shield the neck, because then they couldn't do the X-ray. They will narrow the beam(collimate) to be sure that only the necessary region is xrayed ...Read more

X ray and plane radiation exposure, do I have anything to be worried about?

X ray and plane radiation exposure, do I have anything to be worried about?

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

How much radiation am i being exposed to in ap full spine and what are the indications for full spine x-ray?

It depends: The health physics society site is an excellent resource on radiation dose and effect: http://hps.Org/. The dose is dependent on several variables, most importantly the patient's size. It takes more radiation to make and x ray of an obese person than a thin person. The average dose for an ap full spine is likely in the 2.5-3.0 msv range. This is about equal to 1 year of ambient radiation. ...Read more

Can fluoroscopy of epidural injection be put on a CD that was done over a year ago? Or do those images not exist because it is a live x-ray?

Can fluoroscopy of epidural injection be put on a CD that was done over a year ago?  Or do those images not exist because it is a live x-ray?

Yes-: if images were saved. You will have to sign a release form. Some places will charge a fee for the disc. Call the hospital or office where procedure was performed. ...Read more

Do X-rays technicians set the doses of the X-ray machines for X-ray exam? How to make sure that I didn't exposed to overdoses of radiation?

They can adjust: The exposure within certain parameters, but most modern X-ray equipment have phototimers that automatically measure the radiation and terminate the exposure when it is sufficient. ...Read more

Hello Do I have the right to ask from my urgent care to provide me the exact amount of radiation of my X-rays? It's can be apart of the X-ray report?

Hello
Do I have the right to ask from my urgent care to provide me the exact amount of radiation of my X-rays?
It's can be apart of the X-ray report?

You can Check: Amount of radiation that comes from X rays for medical imaging is very small and generally safe. Different parts of the body would need different amount of radiation to have a good quality X Ray picture. The amount of radiation is not necessarily provided in the report You can definitely ask you health provider about it if you have any concerns about this matter. ...Read more

Does bone scan process involve any exposure to radiation as in x ray?

Does bone scan process involve any exposure to radiation as in x ray?

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

Can indirect exposure to radiations from an X-ray cause any harm to cardiac patients who have had multiple angioplasties?

Can indirect exposure to radiations from an X-ray cause any harm to cardiac patients who have had multiple angioplasties?

Probably not: People who have multiple angioplasties are no more injured by indirect exposure to xray than other people without heart disease. The degree of harm will depend on how much exposure to xray the individual has had. ...Read more

What is the purposeful of doing the fluoroscopy examination? Why it has to be this except e.G. Ct or x-ray? Why fluoroscopy is so important?

What's wrong?: Like any test fluoroscopy seeks to answer a specific question, commonly screening for oral, esophagus, stomach or small bowel disease. It is less commonly used to evaluate the colon than in the past. We even evaluate diaphragm motion with it. ...Read more
