More specifically, if I record ultrasound on a muscle when the limb is cold, would I not be able to see fascicles as well as if I record ultrasound on a muscle at normal temperature?
Any insight on how temperature affects ultrasound image quality/resolution is appreciated!
Hi Avery, I have no first-hand knowledge, but if you have access to an ultrasound I'd be tempted to slap a cold pack on the ole forearm and test that out for myself rather than waiting for answers on here.
No. It should not. Your muscle and blood stream are good thermoregulation system. Your body temperature maintains in a very good narrow range. The ultrasound traveling speed will not be impacted. Thus, the quality and resolution will not be affected.

You have answered a different question than the one posed. Mr. Hinks will be purposefully changing the muscle temperature by application of cold to a limb.
Unless the cold temperature causes considerable body quiver or contraction, the image will not be affected. However, even it happened, the quality of image may not be affected. I don't see any physical factor affecting the quality of image.
Hi Avery,
We are working on a similar issue. There are some published articles that can help you. For example: 10.1177/0161734618800660, 10.1109/MSP.2017.2773338, 10.1371/journal.pone.0266446.
With the information we have been reading, we think that there are changes, perhaps the question is how much it changes and in what variables of the image (Is it clinically relevant?).
I hope you find the answer.
