Nuclear Medicine - Bone Scan

[Rubycon]

Anyone have this and been so hot they get pulled over by "the authority" because the radiation set off an alarm?

 

[bradley]

I only heard about a similar situation March of this year: the TSA detecting a high isotope reading aboard a Chicago train wasn't a piece of luggage, but the owner of the luggage himself. Apparently nuclear stress tests set off false alarms quite routinely.

I have done CT scan but I didn't bring the anti terror unit to my house.

A CT scan is not a bone scan.

CT scan uses rotating xray beams to reconstruct structures based on the absorption pattern of the tissues involved.

Bone scans administer radioisotopes for uptake into bones (or associated tissue). This is then measured based on their decay and imaged for hotspots.

Had a bone scan done a few years ago. I didn't set off alarms. i just went home to bed

I think I had bone scan done too. You had to drink the god awful stuff right?

Bone scans are typically an injection. CT's will have you drink a contrast agent if required.

As for me, I've had one done and the only thing I really remember about it was a cordless phone (this was back in the late 90's) having a lot of static when trying to talk on it later that night.

There was a period of time the docs were worried about me getting malignant tumour so I went through all sort of tests. I know I have done MRI, CT, Bone scan. Just not sure about the details :awe:

"Just not sure about the details"...Are you OK now? They definitely diagnosed it as benign and no future follow up study was recommended?

I was told to refrain from crossing the border for a few days recently after having a short-lived isotope injected to check my heart circulation before & after a stress test.

I only heard of this, but I hear you get to spend your time in the radio-ward with lead lined walls and your urine and poo become radioactive waste and are carted off to nuclear storage sites

i had it done 6-7 years ago but never had that happen to me, had no side affects at all for me.

This is true but a different procedure than bone scan.

Patients that stay in the hospital are undergoing treatment for their hyperthyroidism. The radionuclide used is I 131 in capsule form taken orally to ablate the thyroid.

Because of longer half life at around 8 days, they are placed in a special room as Rick had mentioned to avoid exposing other people to the radioactivity.

"How long you need to stay in hospital will depend on how quickly the excess I–131 leaves your body"...as mentioned in here...http://www.bupacromwellhospital.com/easysiteweb/getresource.axd?assetid=1584&type=0&servicetype=1

This is an "interesting" video.

Pity they didn't show the image coming up on the scanner, that's one of the coolest things to see. Essentially it appears spot by spot, as the camera captures each photon.

Actually, gamma cameras are unbelievably inefficient at capturing gamma photons. Because gamma photons are impractical to focus, you can't rely on just getting the x,y coordinates of where the photon hit the detector, unless you put a collimator on the front of the detector so that only photons travelling directly perpendicular to the detector get through.

The collimator is basically an inch thick slab of lead, with thousands of tiny holes drilled through it, basically reducing it to a honeycomb structure. Photons travelling exactly in line with the holes will hit the detector. Photons going at another angle will have to pass through a lot of lead, and get absorbed. The result is that the x,y coordinate where the photon hits the detector represents the x,y coordinate of where the photon originated from (the z coordinate of the origin is lost).

P.S. did anyone notice the lead lined syringe containing the isotope solution (Sodium pertechnetate; Na TcO4). It always disappointed me that MnO4- is such a nice color, that TcO4- is completely colorless.

That's not accurate, you can receive IV injections for MRI's and CT scans as well as drink the oral contrast. Many times a combination of both.

For a bone scan you get an IV injection of radioactive isotopes.

i remember when i had the bone scan. the bring in a medal canister with warnings all over it. then they pull out this huge needle. At this point i was like WTF!

they then put a iv in and put it through that. i was a little worried...

That could have been a perv neighbor using a superheterodyne scanner! :biggrin:

It's easy to "open up" a scanner to listen to all the good stuff. When cells were analog, listening to those you could literally hear everyone, your neighbors, even the crook politicians blabbering away!

Adding a scout device, the local police could not even hide. Within milliseconds of keying their mic, the carrier would be discovered and locked on and at worst you would miss the first word spoken...

Even today, you know the phrase, you never know who's listening but if I don't talk they don't hear...

I had a bone scan done earlier this year. The hospital warned me that I would need to present the TSA with a special form if I was planning to fly later in the day.
