Magnification Mammography relative dose

By

I often see it stated that manification mammography requires a higher dose than contact. I can understand this if using screen film image receptors with the same speed film, but it doesn't make sense for digital mammography. Same object level noise will mean same dose regardless of magnification. Higher dose is only required if same pixel level noise is needed. Can anyone help explain why it is taught that the higher dose is a disadvantage of magnification?

Onetonline salary search change?

By
Did this change? I am having a hard time finding the same lists I saw 2 months ago. https://www.onetonline.org/link/summary/29-2034.00#AdditionalInformation https://www.onetonline.org/link/localwages/29-2034.00?st=OR&p=hourly I used to be able to see wage by area and sort it by state and see the differences per state and per city in every state. I can't seem to find this same list anymore. I can see a bell curve but I can't sort by state or wage or anything.

Question regarding ultrasound

By
Hello radiologists, I have a quick question regarding ultrasounds of the scrotum. (Not asking for medical advice just wondering about something). I’ve done an ultrasound of the scrotum and the radiologist only took pictures of the right side of the testicle and then the left side but not in between so my question is, do ultrasounds show all “angles” of a testicle or does the device need to be held at various areas to show a full testicle? Because if only one side of the testicle is seen then wouldn’t the other side be as important in diagnosing something? Thanks! submitted by /u/doomyboomy [link] [comments] source https://www.reddit.com/r/Radiology/comments/oi2nmk/question_regarding_ultrasound/
