Input on inflation gas for MRI research of the deceased lung

By

Hi all.

I am looking for some input on a research project revolving MRI scans of the deceased.

I currently working of a phd-project with the main goal of improving lung scans of the deceased. As a pilot project we would like to make an MRI of the lungs, but we need some contrasting agent to inflate the lungs with.

Studies exist were 129Xenon and 3He have been used with great success to visualize diffusion capacities. We would like to do the same on the deceased, but the problem is these gasses are expensive and scarce.

​

Since we are investigating deceased subjects, we have the benefit of not having to think of the health of the subjects (only the personel), so does any of you have a suggestion for a contrasting agent thats more inexpensive and available that could be applied?

We have developed methods for ventilating the subjects.

​

Any input is welcome!

I got into the Rad Tech program!

By
I just want to share with you that I finally got into the program at our local community college and i’m starting this summer. For context, I’m already 30yo with a prior BS degree and decided on a career change. During the pandemic until this semester, I took my time to take all the pre-reqs and GEs required while working. I also volunteered at a hospital for over a year. It was optional due to COVID, but I still did it to get the brownie points. I finally applied last March 2023 and received good news last Friday. The program is based on a pointing system, so I think having good grades really mattered. It was my first time applying and the only program I applied to. I didn’t know it was possible to get in on your first try because of all of the stories I’ve been reading, so don’t lose hope because it’s possible! Wishing everyone who’s applying this year good luck. You can do this! If you have questions, I will do my best to answer them 😊 also if you have tips on how to survive this ...

Do rad techs/sonographers deal with vomit often?

By
Hi there! I’m currently considering going to school to be a rad tech or sonographer but I’m struggling to find out if you guys deal with vomit a lot. I am emetophobic (phobia of vomit) and, while I think I’d like these jobs a lot, it does worry me to think about having to deal with it often. Thank you for your help! submitted by /u/pootscoot1 [link] [comments] source https://www.reddit.com/r/Radiology/comments/p5y0aa/do_rad_techssonographers_deal_with_vomit_often/

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/
