I love this video. I was struggling understanding the differences between KeV, kVp, mA, and mAs

How's mA related to organ types, penetration, contrast, and spatial resolution? And what makes us decide on whether to choose lower mA and higher time or the opposite?
@TheNettforce2 жыл бұрын
Authman the first decision to make is the kVp which determines the contrast and penetration (see our kVp video) and yes we discuss the organ dependence in there. Then the mAs is used to fine tune the tolerable noise to in the image. The high contrast spatial resolution (as measured by MTF see our video) is not dependent on the mA but for low contrast tasks the mA will limit visibility which is the point we were going for in this video on mA.

Hi, could you explain why in a chest x-ray the mAs is so low when the kVp is so high? I can't seem to get my head around this
@HowRadiologyWorks Жыл бұрын
We have a video on kVp as well, make sure to check it out. The kVp will be lowered for iodine and barium imaging and bone imaging. Since these chests are often focused on soft tissue and air the is not a big driver for low kVp. At high kVp there is less absorption in the tissues so the dose is lower. Then after the kVp is fixed we select the mAs based on the noise in the image. Since there is a lot of air in the chest it is less attenuation and so the mAs can be lower.

@@HowRadiologyWorks why is there less absorption in the tissues at high kVp and therefore the dose is lower? I really can't understand this since high kVp means more penetrative power

@eyasutekle25535 ай бұрын
@@vinceiodice824 The absorption dose depends on density of the body and on the amount of kVp. Kvp is something that gives energy for electrons to pass through. So, if we increase the kVp the radiation gets energy to penetrate and helps to get through. As a result, the dose of radiation a patient absorbs will be smaller and it's less likely to cause harm.
