Hi @johnruuu, bone scans require an injection (a radioisotope, not contrast) and imaging is done post injection (2-4 hrs later) so that the isotope can circulate through the body. I don't think they do any scans prior to the injection. Hope that helps. Please let me know if you have any more questions. Have a wonderful day!
I have canceled my first one in January and now I have another one in February. I have a known allergy to contrast dye and I am tired of people telling me there can be no reaction. Can someone please tell me what precautions are taking if something should go wrong? And what is the amount that is put in? I am so stressed out about this test but if I don’t do it what are my options? Finding two bone lesions on a CT scan on my pelvis and I don’t know any other alternative. Can someone please help me?
Hi @GigiQ597, a bone scan does NOT use contrast dye, so please feel a bit of relief with that concern. The injection that we administer is a radiopharmaceutical. It has 2 components. The component that allows us to take our images is an element on the periodic table called technetium. We use an isotope of technetium that is radioactive, specifically technetium 99m. It is suspended in saline to form an ionic compound called pertechnetate (99mTcO4-) and then mixed/tagged to the second component. The second, non-radioactive component of the injection is called Medronate, or MDP (methylene diphosphonate). This is a phosphate based compound. Phosphates are one of the building blocks of bones, this is what will bring the radioactive component to the bones so that we can assess how they are building/remodeling. The full ingredients for an MDP vial are: medronic acid, stannous chloride dihydrate, p-amniobenzoic acid, and a small amount of either sodium hydroxide or hydrochloric acid for pH balance. When the components are mixed, even more saline is added, which makes up the majority of the volume injected. This injected volume is based on the concentration of the radioactive element and not the MDP. Each dose is an average volume of 0.2 mL, with a range of 0.05-0.5 mL, depending on the dilution. The amount of radiation used is 740 MBq (megabequerels). This is a measurement of how many gamma photons are released per second. This amount will decay over time, having a half life of 6 hours. This means after 6 hours there is only 370 MBq remaining, after 12 hours there is 185 MBq remaining, and so on. MDP mainly leaves the body through the kidneys/urine. With increased hydration throughout the day the tracer will leave the body even more quickly. Side effects from this injection are extremely rare. So rare in fact that we refer to it as having "no side effects". Occasionally, someone may have a sensitivity to one of the components of the MDP vial. This sensitivity can cause someone to feel mildly unwell or slightly nauseated. Usually these effects are gone by the following morning. I would estimate we have 5-10 patients per year report these effects, out of the >10,000 bone scan patients we see each year. We have never had a patient report an allergic reaction to their bone scan injection. Our Mayfair Place location has a "crash cart" located in the nuclear medicine department. This is because we perform higher-risk cardiac examinations at this location. This cart is stocked with an epi-pen if it should be needed in an emergency. All of our technologists and our administrative assistants are certified in CPR for healthcare professionals and have years of experience and first aid training. There are also radiologists on site. The bone scan itself is often an easy and relaxing procedure. The injection is done into a vein using a very small needle, and it usually takes less than a minute. Sometimes pictures are done immediately following the injection to see where it goes in the bloodstream. It then takes time for the tracer to make its way into the bones, which is why this exam has 2 parts. The wait time between appointments can be between 2-5 hours, depending on which time slot you are booked. If you prefer a shorter or longer delay you can ask your booking agent which time slots will accommodate this. For the delayed images they generally take around 30-45 minutes in total. Either whole body images will be done, or partial body images. We often perform a SPECT/CT image, but not always. This is a 3D image of the bones combined with a low-dose CT scan. There is NO CT contrast used for this portion. It is essentially a 3D x-ray that will make our bone scan images clearer. The radiation from this is very low. Please let us know if you would like someone to contact you to discuss any further concerns. Thank you and have a nice day. Mayfair Diagnostics
@@MayfairDiagnosticsOfficialThank you very much for taking the time to answer and explain everything to me. I do appreciate it. Can you also tell me due to my low kidney function and waiting also to see a heart specialist can this injection have any bad effect on my kidneys or heart? Thank you.
Hi @pamelaharris4540, the area that's being scanned needs to be in the middle of the magnet. Depending on the patient's height, their head could still be outside of the zone itself. As for if the replacement interferes... if it's ceramic no... if it's metal it might cause what we call "artifact" or flares but we do them for patients quite often that have had TKR or THR. I hope this helps answer your question. Please let me know if you have any more. Have a wonderful day!
I had one done recently. Absolutely fine. Just lie there and Dont be surprised if they strap your feet to the triangle box thingy. The nurses are good and if you dont look up you dont know theres a box over your head. Oh wrong scan haha i had a normal bone scan. Glad i disnt see this one beforehand! Be fine and marie curie made the use of radio activity possible. Honestly if claustraphobic a word with gp or doctor beforehand might give you something to take edge off
Hi @janinahendrych9065, I just wanted to share an article about radiation dosages that you might find useful. This article also includes a downloadable chart for future use or reference.

How did it go? Had mine last week, and it is much less claustrophobic vs. an MRI. Arms were secured to my sides, and feet taped together in case of any sudden movements during the scanning process.
Its very claustrophobic. Despite having open sides it's literally centimetres from your face. It stays there for ages and I had a panic attack at the end.
Hi @JLU-st6sd, in regards to taking off any jewelry, you do not have to take it off - unless it's directly in the field of view of the area being examined.
Had an MRI done recently and thankfully it was only for 20 min. I have ADHD and claustrophobic so it was very difficult to stay still. I suggest dont open eyes. Wear a cloth face mask
doing mine next week. hopefully the technician is nice and helpful like this young lady
All I am worried about is that of radioactive thingy
I don't want to turn into a hulk
Damn, I have an appt. tomorrow and just watched another video about this and they said nothing about any injections. Yikes, now I'm scared again.
Thank you so much, now I got it what exactly the bone scan ❤.
why aren't the scans WITHOUT contrast doen FIRST to completely avoid having to return 2-4 hours later?

IV with radioactive marker, wait, lay in machine. Mine was painless except the IV and laying on my back
This tech should be promoted to a HR training facility.

Nice and precise.
Wow brilliant video thank u for sharing so useful mine will b in two days🥰🥰🥰🥰❤️❤️❤️❤️🙏🏽🙏🏽🙏🏽
Does having hardware from the knee to ankle affect the procedure? Or is it even possible to perform the full body scan with the hardware therein?

How much radiation is going through the body ???

do you have to take off any jewelry

Excellent - what do I do if I can't be still 45 minutes on my back! No way, ughhhh
I had mine today
Doing mine tomorrow
My husband is doing this today at 12:45pm

Hi Mobile,
There is no associated cost to to exam as it is covered under your Alberta Health Care Plan.
I'm goin this coming Thursday.
What' was Yours Result???
