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/
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.
3/
UL: No doc, I only kid with those who can take it. I know you can handle it. I heard how you were with @IoannisNL & his friends at the “Howl at the Moon” – Piano bar last night

MP: Ok, that enough. I am now shifting my mind to work. See you tomorrow.

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?

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
