15% rule Radiology problems

[@MaryPatch-oq8mm]

A lifesaver! Thank you for explaining it so well.

[@wendylorenzo1555]

you are great !!!! thanks for the help .

[@juliebielefeldt7834]

You explained this so well. Thank you 😊

[@Favmany67447]

Could you show how to find the seconds and mA?

[@meaghanpiretti7340]

mAs is simply ma x S. Just multiply the two together.

I HAVE SUCH GREAT GRADITUDE FOR YOUR UTUBES, I HAVE LEARNED OR UNDERSTOOD THE WHYS OF ROATATING OR DOING A PARTICULAR POSTION. I DO HAVE A QUESTION, I ASKED IF I HAVE A PT THAT IS A HYPERSTENIC PATIENT 300 LBS ON ABDOMEN, I WAS TOLD GO 85 KVPS TO 300 MAS I JUST GOT CONFUSED ON THEN WHAT?????

[@meaghanpiretti7340]

I am not understanding your question.

[@shardaymcfarland2654]

I thought in another video you stated to 1/2 mAs when you decrease by 15% 😩 ???

[@meaghanpiretti7340]

No. Unless I made a mistake when speaking. But that wouldn't make any sense. They go opposite of each other.

[@shardaymcfarland2654]

@ Oh ok! So, always increasing kvp means to 1/2 mAs and when you decrease kVp you double the mAs ?

[@makypairett]

still such a helpful video, thank you so much

[@azratariq8572]

I have question.if we decrease Kvp so decrease quality I don’t understand plz help me

[@meaghanpiretti7340]

kVp controls the beam quality.

[@aidearellano4296]

What if this is the situation; original technique: 300 mA, 20ms, 120kVp. New technique: 400mA, 120kVp, ____ms?

[@meaghanpiretti7340]

first calculate the original mAs, 300 x .02 ( mA x sec). Then divide by 400 mA. change the answer to ms.

[@adolfoflores660]

hello, do you have any videos of the 5 cm rule? for patient thickeness and how much the mAs changes?

[@meaghanpiretti7340]

No, that is not something that I teach. Calipers have been taken off the ARRT so I don't cover this.

[@adolfoflores660]

@@meaghanpiretti7340 really? That’s interesting. I’m currently in radiography school and I’m learning this. Thank you so much though!

[@donyakk]

its great info but you speak very fast

[@meaghanpiretti7340]

Thanks for the feedback. These videos are quick reviews for my students. They have the lecture in person with me already.

[@whitneylarkins1265]

Girl you most definitely do not speak fast 🤣🤣
