Conversations between O-arm and MP re RSNA meeting

O-arm: Hey doc! How is it going over there @rsna #rsna2022? My cousin’s teenage daughter was telling that you are posting a lot on Instagram. What’s up with that?

1/
MP: Why can’t we #MedPhys not allowed to be instagramers? @aapmHQ

O-arm: I was just teasing you doc. As a teacher it is always best to make your students feel comfortable communicating w you, especially if they think you can understand them

2/
MP: Yes. Is that all or did you want to ask me something else?

O-arm: How is the technical exhibits over there? Anything new that I need to be concerned about, that would make me obsolete?

3/
MP: There are number of new things, but you don’t need to worry. Our surgeons loves you guys. Only thing is as long they work with us to keep you giving them high-quality images, all is fine. BTW, guess what I spotted in the exhibit area?

O-arm: I can think of many, but what?
4/
MP: Actually, I spotted “baby yoda” watching over a portable x-ray unit

O-arm: “Fine that is” with me, I would say

MP: Let’s stop mimicking YODA, that’s my territory

O-arm: Ok doc, when are you coming back?

5/
MP: I am heading back today as soon as our paper is presented. I will see you soon.

O-arm: Ooo, “wait, I can’t”….

Conversations between UL & MP re studies w & w/o contrast
UL-Ultrasound
UL: Hey doc! We have a new probe (7.5 MHz), & he keeps bugging me about studies w & w/o contrast with #CT & #MRI

MP: That’s easy girl. Why are you having difficulty explaining.

1/ ImageImage
UL: You don’t know doc; this probe thinks he is high frequency & don’t seem to agree on what I say. Just tell me how I can explain in simple terms.

MP: I will try by two images I took at RSNA. Consider 1st photo without contrast & then 2nd photo as study with contrast
@RSNA
2/
MP: See the differrence

UL: Not bad doc, I will try explaining to him as you said. BTW, the #RSNA cutout looks good, please don’t mistake me, that is better than the one with contrast (2nd w you)

MP: Girl, you always pull my leg. I should stop talking w you.

Conversations between MP and IM (Imaging Modality)

IM: Hey doc, why do u guys insist on placing Aluminum (Al) or Copper (Cu) filters in front of my mouth?

MP: It is mainly to filter out some of the lower energy x-rays coming out of Ur mouth.
@RSNA
1/
MP: Lower energy x-rays only increases patient skin dose & do not contribute to the overall image quality. Hence, by placing certain thickness of filter materials, we shape x-ray beam coming out of Ur mouth.

IM: Well, then why do U use only Al or Cu, why not Pb?

@aapmHQ

2/
MP: Because Lead is used to stop all x-rays. In fact, Pb is used in collimator housing to shape the x-ray beam coming out of your mouth, so that it is within the desired region. On the other hand, Al or Cu is used to filter out lower energy x-rays, making beam harder.

MP: Hi there, nice of you to interrupt our mtg, was it so important!

DBT:Digital Breast Tomosynthesis
1/
DBT: No doc, but our 2Dmammo were sharing Ur tweets of Chicago yesterday w #Biopsy & me, so I wanted to ask if u are working hard or hardly working
MP: Well “all work no play makes Jack (in my case ‘a Desi’) a dull boy”, so yesterday was fun but today was all work
@aapmHQ
2/
DBT: I heard @DrLizMorris who came to @Hopkins_Rad was a key note speaker today
MP: Hi ‘Rad’ excuse us. Yes, I just returning from her talk. Girl, you would have loved it. She really talked about what Y’all do for breast cancer detection

Conversation between MP & O-arm

MP walking with x-ray output measuring devices

O-arm: Hey doc, what is “Air-KARMA”? Until now I heard ‘Good Karma’ or ‘Bad Karma’, & am sure you doc have lot of ‘Good Karma’, then why introduce a new term ‘air-kerma’?

@RSNA
MP (smiling): Dude, it is not “Air-Karma”, it is “Air- KERMA (Kinetic Energy Released per Unit Mass)”. If you asked any of my residents, they would have told U.

Air-Kerma is measure of x-ray beam intensity measured w ion-chamber which aides to estimate patient risk.
@ICRP
MP: In fact, I am here to measure the ‘air-Kerma’ for Ur system

O-arm: Thanks! then why “air-Kerma” is always expressed in “milli-Gray”?

Conversations between MDCT & MP

MP: Hello buddy why are U groaning, CT techs called me to come & check u out

MDCT: What can I say doc? I feel “imposter syndrome”, even though I scan as many patients as they put through, I feel I am not appreciated
1/
 @RSNA
MDCT: I feel that I am not appreciated, because of that I feel very inadequate.

MP: It is quite normal. I feel quite the same often. But we can’t let it dwell in our mind. BTW, glad you spill out what you feel, I am here to talk you through.

2/
MP: U have to be proud of Ur actions. U scan >50 patients in a day, only limited by how fast our techs can put patients through

MDCT: That is one thing, even though I scan >50 patients, but my cousin MRI gets all the credit

Conversations between C-arm & MP
C-arm: Hey doc! I see that you are heading to @RSNA mtg.
MP: How did u know buddy?
C-arm: Well my cousin in Chicago told that they are expecting a large crowd coming to town. Also I see you humming & running

MP:Correct

1/
C-arm: when you are there doc, check out the #AI lane of exhibits
MP: why are you interested?
C-arm: it’s a long story doc. First we heard that they are putting on #AI in our new cousins telling it will make them less noisy
MP: why do you think it is bad?

2/
MP: Doesn’t it allow you to less #radiation which will help our patients & bring y’all good name?
C-arm: Doc, if it was only that, we are happy. But #AI guys have gone too far
MP:How?
C-arm: Doc, didn’t you see recent study from #Finland
MP: Yes, I read it
