Hey Michael, I am new to your channel. Based on your experience, what is a proper way to learn anatomy to master radiology. My guess Is: 3D anatomy, then cross sectional anatomy, then dissection? How is it taught in radiology school?

[@LearnNeuroradiology]

Wow, that's a big question. There are as many ways to learn anatomy as there are people trying to learn anatomy. Most radiologists start learning anatomy while in medical school. This is a combination of books, dissection, and lectures. For books, you might try: Moore's Clinically Oriented Anatomy amzn.to/37qQZuo or Netter's Atlas of Human Anatomy amzn.to/2HhAxSq Anatomy: A photographic atlas amzn.to/35lzBUY Some sort of virtual dissection might be useful as well. There is something called the Visible Human Project, that has a number of applications. For example, this one from University of Utah: webpath.med.utah.edu/HISTHTML/HISTO.html#1 I'm sure there are a lot of online lectures on youtube as well that you can check out. Then, once you have some baseline knowledge, radiology is mostly on the job learning where you look at things one at a time and learn by doing. Hope this helps.

[@quixotic4233]

Inspired by the comment on secondary hippocampal sclerosis being more common in the pediatric population: should the approach presented here be considered age specific (e.g. for adults)? Would certain age groups (infant, toddler, teen, elderly) reasonably merit variation in the search pattern?

[@LearnNeuroradiology]

It's a good thought, and we do change our attention a little bit, but for the most part the same search pattern is still applicable. You might just be a little more on the lookout for certain things based on the age. For example, younger patients are more likely to have a low grade tumor (DNET or ganglioglioma) while older patients are more likely to have a metastasis. You gradually learn to be attuned to these things while keeping the same overall pattern. Great question though!

[@LearnNeuroradiology]

@@quixotic4233 Thank you! I'm glad you appreciate the channel and thanks for tuning in. My goal is to keep making useful videos!

[@12amirm]

Great Do you have more lectures like this How about c spine and T spine

[@LearnNeuroradiology]

Glad you liked it. We have a bunch of other similar videos. If you want search pattern oriented videos, check out the search pattern playlist: kzbin.info/aero/PLYSUjrPFpR_nxTKgPr2J65zlCrH1NlxWp We have videos for MRIs and MRAs of the brain and neck, MRI of the cervical spine, and more. We try to make more but we only have so much time! Check out the whole channel here: kzbin.info/door/6RICkCkDRjxar5rdsVJStA

[@ashishmulavekar73]

Very nice..excellent.. can it work on 1.5 T MRI?

[@LearnNeuroradiology]

Yes, all the concepts are essentially the same at 1.5T. The resolution of fine hippocampal structures and small cortical malformations is less, but still acceptable

[@ashishmulavekar73]

@@LearnNeuroradiology thanks a lot

[@eltiarribero]

6:14😜we don't film anymore. I was under the impression that on Pacs Radiologists WL back and forth accordingly. 🤣Excellent video tho.

[@LearnNeuroradiology]

Yes, we do have the ability to window and level accordingly, which is what we are giving tips on how to do. However, even though there is not film there is still a default window that comes over on PACS. If you don't change it, you may miss something important.

[@immane75]

What about perfusion and ASL ?

[@LearnNeuroradiology]

Perfusion MRI (including techniques such as DSC, DCE, and ASL) does not play a role in the routine evaluation of seizure. It may have a specialized role in seizure localization to look for areas of abnormal perfusion which may have concordance with EEG and other findings, similar to SPECT. However, it's not widely performed. It is a topic of active research and you can find a lot of articles out there, such as this: www.sciencedirect.com/science/article/pii/S1059131118307052

[@immane75]

Excellent presentation . What do you think about 3D sequences ?is FLAIR 3D enough ? what about 3D T2 FSE ? is MPRAGE done in 2D or 3D ? Is T1 BRAVO from GE equivalent ? Thank you very much for your response

[@LearnNeuroradiology]

This is a complex question but I'll try to answer the main parts: 1) 3D sequences are often a suitable replacement for 2D sequences, although they can add time and may be more sensitive to patient motion. The tradeoffs have to be considered. 2) 3D FLAIR in many ways is equivalent or better than 2D FLAIR and can probably be used 3) Depending on the implementation, 3D T2 sequences such as SPACE have less tissue contrast and may not be as effective at seeing hyperintensities in the hippocampus 4) MP-RAGE is a 3D T1 sequence originally Siemens specific but now available on other scanners. BRAVO is a similar sequence on GE scanners. Generally speaking you just need a high resolution 3D T1. These are complex answers but have to be tailored to the benefits and drawbacks of the individual scanners that you have.

[@nurjahan31]

I got the results of my MRI and shows a 1cm CSF signal intensity lesion in the right temporal lobe...What means that?

[@LearnNeuroradiology]

It's hard to tell without knowing, but there are a number of small cysts that can occur in that regions, such as arachnoid cysts, choroidal fissure cysts, and tumors that have cystic components. If the report didn't suggest that it was a tumor, it's probably a benign (relatively normal) finding, but you can ask your doctor for clarification.
