Thank u ..it was very helpful ❤
hey, just today got intense heating of an area on my knee during MRI scan. NOBODY informed me that I had to watch out for burning sensation or that may be dangerous. for 15 min it was normal. Then I felt a burning sensation, I was surprised, then it went away briefly then came back stronger. After the third time it felt tile my ligament is going to explode and I squeezed the bal. Nurse came in and instead of explaining anthing she simply asked me "do you want to stop the procedure?". I'm like "I have no idea, is it safe to proceed while I'm feeling burning and like my tissue is going to explode? Can it cause me any harm?" She said, no o harm can occur. So we resumed. I felt no burning after it was resumed, but I feel like my knee suffered permament damage and it feels injured. Heating up an injured ligament can cause tear of tissues. Fucking unprofessional ignorant bastards injuring patients during a check up. (I'm based in Ukraine. MRI was done in "EUROCLINIC" in LVIV city).
Hi I work with these magnets. This is the reason why there is safety checking, we ask patients wether they have metal inside their body and outside their body i.e brain shunt, heart pacemaker etc. This things can still be scanned with limitations on the power that we use, it is very important to tell the technologist your health and history of surgeries that involves metals and accidents such as metal shrapnels that went inside their skin. If there is a case that the patient had an unknown metal shrapnels accident specially in the eyes, we tend to abandon the scan and request for an xray. This is why MRI safety questionnaire is in place. Now a days most surgeries that involve metals are MRI compatible so most of MRI technologist knows how to deal with patient that has it. With regards to your query, as long as there is no metal(specially ferrous magnetic i.e iron based) attached on your knee you should be fine. With knee scan most of the patient would comment that they experience a kind of pulling sensation around the area of the scan, this is because the water molecule aligns with the iso center of the machine we also use specific camera (MRI coil) on the part that is being scanned and this entails safety as well. I hope I am able to answer your worry.
@@marifeltiamsic9471 hello. It's not a worry. It's a statement of what happened. My leg was feeling ill for 3 days at least after that. It seems I didn't suffer too much damage (or I'm failing to detect the damage, since it's under the skin and I'm not stupid enough to force load on my injured ligament just to prove a point). Good thing I signaled the MRI stuff to turn it off when I did, other vice I would have suffered that burn 100%. The only thing I found out from your comment is that if you limit the power it's possible to scan with non-ferrous metals present. But failed to highlight that even with no metals present the patient can still suffer a burn if too much power is used (which I'm sure is what happened to me). It's all about money, more power = faster scan, faster can put another patient and take their money.
Thank you for posting! I remember reading in the book of Radiology Physics by Christensen: KvP is Quality of the x-ray photons generated (their energy; weak - strong), and mAs is the Quantity of photons produced. I hope it helps!
Is that check source harmful ? Should we let the geiger counter in our houses ?
This was very helpful to me. Thank you
One paragraph from the book "X-Rays for dummies" turned into a 9 minute video. Not quite sure what to think about that.
Also basic translation for multiplication factor for the values on the reader equal to sensitivity of the measurement, x100 would mean its less sensitive reading a larger amount 50 100 150 and 200 rems and 1000 1500 is high enough to kill immediately, I'm guessing the time exposure and amount of radiation or the rate of exposure moves down in lethality taking a linear rate but that's just a guess
With all these low yield war heads and ww3 talk this is great 👍🏾
Im a new dental assistant going to get my xray license and KVP vs MAS was supper confusing for me . Was so hard to find a video that would explain it in a way I would understand. You did a great job explaining it. Thanks and keep up the great work
Wow this is so clear
Wow, this is fascinating to see. I really hope you used a Geiger counter before handling any of those items/taking them with you though
mR/hr.....? What is the "R" unit? rem, rad, roentgen?
It should be rem as it is a US made instrument. The use of the rad means you know which type of radiation you are measuring as there is a conversion factor called the RBE or Relative Biological Effectiveness. The RBE is 1 for beta radiation, x-rays and gamma rays, so 1 rad = 1 rem. For alpha particles the RBE is 20, so 1 rem = 20 rad, as the alpha particle is more damaging to biological material. The Roentgen unit is the measure of ionisation of dry air, an older physics unit, so more appropriate for an ionisation counter.
@@karhukivi Thanks.
@@jayytee8062 Its Roentgen, exposure rate (expressed as milliroentgen per hour or mR/hr).
Please create more first year videos to help us beginners! It has been very challenging to find videos that are actually clear and thorough.
AWESOME VIDEO !!!! This helped me very much! Thank you!
Great content.

What are the requirements to become an RSO? Is there a course to get certified? The reason I ask, I basically already do this at my current position. If you could help me out with this, that would be awesome!
Hi Justin - the requirements to be an RSO can be complicated based on the types of radioactive materials use as well as the regulatory agency (NRC or Agreement State). There are many companies that offer 40 hour RSO courses, either in person or online. Those courses are a great supplement but are often not sufficient to provide all of the required training and experience necessary to function as an RSO. Feel free to drop us a note at [email protected] if you'd like to chat about what your best options are.
@@olympichp I reached out to my state this afternoon after I left this comment. Apparently there isn't a license required to be an RSO here. But in other states, do you need to have an active x-ray license in order to get certified as an RSO?
May I know which protocol acquisition you chose in the system for this QC?
For this acquisition, we chose "Example Tomo" from the Siemens protocol list. However, any tomographic protocol will work as long as the parameters are changed correctly.
I read that kVp also increases qantity of electrons going from the anode to the cathode. It increases both quality and quantity, while mAS only increases quantity. Is this true?
It is true that increasing the mAs increases the quantity of electrons going from the anode to the cathode. However, increasing the kVp only increases the energy of the resultant X-Ray beam - it doesn't increase the quantity of electrons.
@@olympichp It is absolutely true that increasing the kVp shifts the mean electron energy to a higher value (more average energy and hence higher penetration), but it is also true that a 15% increase in kVp is equivalent to a 200% increase of mAs. This is due to the physics of X-ray generation - the more average energy the electrons have when hitting the anode the more X-ray photons are being generated. However, indeed, increasing the kVp does not change the number of electrons generated at the cathode.
These videos are so helpful. It’s so hard to find information like this. Thank you!!
Thank you so much for your feedback - we are so happy you find them helpful!
I feel like I'm so close to understanding this and I still can't 😭
Please reach out by email if we can help you understand anything related to this video.
Thank you sir for this informations
Thanks a lot ✨✨✨✨✨✨✨✨✨
You're welcome 😊
Great video. Explained the difference between mAs and kVp so clearly.
Thanks so much for your feedback!
Your channel deserve more subscribes sir
We agree! Share with your friends :)
@@olympichp sure sir
I loved your video sir... Keep making videos.
Thank you so much!
If KZread allows it, I'd add that this is for Nuclear Medicine RSOs. Over half of this video doesn't apply to an RSO in a clinic/SCA setting or in a hospital that doesn't have Nuc Med. You also don't mention quite a few basic things 95% of RSOs monitor like lead inspections, PM and QA of machines, repeat/reject logs etc. I would just tell most RSOs watching this, it isn't going to tell you much unless you want a very general overview of an NM RSO's responsibilities.
Hi Matt, and thank you for the feedback. You're correct that many RSO's have additional duties outside of just RAM licensing duties. The ones you mention are common and there are many more. In this video, we focused on the duties of the RSO as they're defined in NUREG 1556, Vol. 9., Rev. 3. to highlight the regulatory expectation of a medical RSO. We updated the description of this video in hopes that will help.
Thanks for this information!
You're so welcome! Let us know if you have an idea or suggestion for an upcoming video.
Giving the people what they want! Thank you for the info!
You're welcome Nic!
I like the breakdown of the records that you should be keeping. I think it would be nice to list the retention requirements for each document. Surveys Leak Tests Sealed Source Inventory Dosimetry Records Written Directives Radioactive Waste Records RSC Meeting Minutes Well Counter Quality Control Reports Survey Meter Calibration Certificates This was great!
As always, you're one step ahead of us Nic :) We will have a Records Retention video coming your way shortly...because...keeping records is super important!
Here is the next video in the series to answer these questions! kzread.info/dash/bejne/Z6V5tK6cfKqbhpM.html
