Thank you for watching my video. If you liked it, please consider giving it a thumbs up 👍. Feel free to let me know if you have any questions, I'd be happy to help you ☺.
This was an excellent video, I have a PET scan tomorrow afternoon for newly diagnosed breast cancer. Thank you so much. Your videos have been so helpful. I'm very grateful 💓
Hm, I don't know what a hynic scan is to be honest, especially not in the context of prostate cancer. I thought it was used to diagnose neuroendocrine tumors.
Hello Dr Paulien. Simple and easy-to-understand video. Thanks for making it! I have two questions. I hear the term decay time, energy resolution and light output quite a lot. Can you briefly explain the significance of having high light output from the material inside the PET system? Also, what is the importance of energy resolution and decay time in PET?
Hi Edmund Chin, thank you for your comment. I don't know all the details about this, but I'll try to answer your question as best as I can 🙂. (1) The light output - as the name indicates - is the number of scintillation photons produced by each incident photon. A higher light output results in a better resolution of the PET image. We want this to be as high as possible. (2) What do you mean by the importance of decay time? Can you specify this question? Energy resolution is the ability of the detector to accurately determine the energy of the incoming radiation. Since no camera system is perfect, no system is capable of determining precisely what energy photon struck the crystal. Instead, the system can only determine within a range of values, what energy radiation it is detecting. The energy resolution is expressed as a percent of the energy of the incoming photons. Instead, the system can only determine within a range of values. If the energy resolution of a camera is 10%, and only 140 KeV photons are striking the crystal, the system will "see" photons ranging from 133 KeV (-7) to 147 KeV (+7). That is, it can only determine to within 14 KeV, what the actual incoming energy really is. Energy resolution is a very important parameter in determining the overall performance of a gamma camera, because it is the parameter, which allows a camera to differentiate between primary photons and Compton scattered photons. This ultimately determines the spatial resolution of the system.
"Energy resolution is important to distinguish photons emitted at the point of annihilation from those that have been scattered (e. g. by Compton scattering in the patient). Scattered photons partly loose the information about the annihilation point and lead to false LORs causing additional noise in the reconstructed image.

It's difficult for me to decide if that's a good option. I love nuclear medicine, so I would recommend this to everyone, but you have to love it too :)

Dear Dr Moyaert, thank you for the videos! Could I please ask what your references are for the nuclear medicine series? Thank you
This was an excellent video, I have a PET scan tomorrow afternoon for newly diagnosed breast cancer. Thank you so much. Your videos have been so helpful. I'm very grateful 💓
WoW,, you made a complex subject very simple and easy to understand. Many thanks for putting efforts.
This is an excellent video! It's very informative, clear, and concise. Thank you for making it. ❤
Thank you for your reply! ❤ It made my day 🙂
How great is this video
Thank you 😄🤩
Big thanks from Bangladesh ❤️
Mam,
I'm preparing for my upcoming MS final Exam watching your videos 😁
Great simplification
Thanks alot
Thank you so much doc, this help me a lot for my physics project. I hope one day i'll become a good doc too ❤️
Thank you so much doctor
great video!
Thank you Jessica!
Thanks Paulien, great video . What is a hynic scan? Specifically relating to prostate cancer, can't seem to find a simple explanation

Please tell me which program did you use to create this?😞
Visme to create the slides and imovie to create the movie 😉
Thanks alottt✨️✨️
You're welcome, Sarayu 😊
Mam I am doing radiotherapy and planning to do msc nmt is it good option
It's difficult for me to decide if that's a good option. I love nuclear medicine, so I would recommend this to everyone, but you have to love it too :)
The thing is to join msc nmt I have to give entrance for that can u guide mam I am interested in nmt
@@priyavardhinidoppalapudi6671 What exactly do you need to know?
Nice and great work doc
Kindly respond to my humble request about my doctorate program ❤
