As a PGY2 rad onc resident, this video was SUPER helpful for contouring. Thank you thank you

[@ThoracicRadiology]

glad it was helpful and good luck with residency!

[@patrickhanks9049]

Very nice video, thank you. The IASLC nodal scheme describes the changeover between lower paratracheal and hilar node stations at the lower margin of the azygos vein on the right, and the upper rim of the left main pulmonary artery on the left, not the carina as you mention in the video. I appreciate the added description of other nodal disease not discussed in the IASLC framework.

[@ThoracicRadiology]

Thanks for your comment, yes you're right I should have mentioned that. The IASLC document describes these nodes as immediately adjacent to the mainstem bronchi and hilar vessels, so that's why I described it the way I did. The landmarks you point out are more accurate. Incidentally, nodes that are anterior to the carina, I would still classify as right paratracheal.

[@wearefortniters]

what is mean hypermetabolic ap window in Petscan

[@ThoracicRadiology]

PET is an imaging modality that uses a radioactive tracer to cause certain tissues to light up. In the case of F-18 FDG PET, the radiotracer goes to tissues that are highly metabolically active. In the case of a hypermetabolic lymph node, that could be due to cancer, or it could be from other things like sarcoid, infection, or other inflammatory diseases. the AP window is a location in the chest.

How to measure lymph node what axis we should measure the long or short

[@serialblesser]

I need ask what's reactive slightly mediastinal lymphadenopathy? I was diagnosed with them, I am worried? Help would be appreciated

[@ThoracicRadiology]

It means your lymph nodes are enlarged. This can be for many reasons. It is important to see your doctor to figure out why they are enlarged.

[@Louloui636]

Can you see supracavicular nodes in a chest and neck ct without contrast???

[@ThoracicRadiology]

yeah the neck CT overlaps a little bit with a chest CT, so if you have an enlarged node in the lower neck/upper chest, it should be on one of those.

[@HMAsad-er9ei]

Hi Rishi, Thanks for sharing a nice talk. Just to ask regarding nodal chart you refereed, it is 8th edition. Are you still using same chart or any updated version (as this talk was uploaded about 3 years ago)? Secondly, i couldn't find any satisfactory answer about few subcentimeter thoracic nodes we see in our routine practice in patient with inflammatory conditions or in known malignancy situations. Referring services expect us to comment on these particularly on 1st / baseline study.

[@ThoracicRadiology]

Good question, the lymph node map is not updated on the same cycle as TNM staging, so yes it is still current.

[@ThoracicRadiology]

Yes I frequently see 9-10 mm nodes in connective tissue disease which I do mention in the report. In known malignancy, I don't usually mention small nodes unless they are unusual, for example enlarging nodes or nodes where there are usually no nodes like near diaphragm, pleura, and internal mammary.

[@zohebmulla3670]

Colon or large intestine ulcers can be seen in ct scan?

[@ThoracicRadiology]

CT scan of the chest? Not usually, no.

[@sakinagadiyeva5900]

Thank you! I have a problem determining chest lymph nodes without iv contrast😣

[@tmorelli1982]

Is a "non-specific borderline prominent" subcarinal lymph node (1cm) something to worry about?

[@ThoracicRadiology]

can't say for sure. It depends on the rest of your medical history and findings on the chest CT. better to ask your doc for this.

[@dr.shaishavishah8532]

Sir which book is considered good to read thoracic radiology for residents?

[@ThoracicRadiology]

[@JohnBaek-z3j]

Amazing video! Thank you I just uploaded a blog post about chest anatomy on my website and used some of the images from this video (with the reference). Please let me know if you don't want your contents to be reused and I will delete them.

[@RagingTortoise]

Out of curiosity, are infraclavicular lymph nodes examined / visible on a thorax CT? You mentioned supraclavicular nodes, but not infra. Not a medical professional, just an enthusiast - so excuse my ignorance :)

[@ThoracicRadiology]

Great question, yes you can see those too but we call them something different. Like if they are under the pectoralis then subpectoral nodes.

[@mahso11]

So lymph nodes do not enhance after IV contrast?

[@ThoracicRadiology]

They do enhance, but they won't be as bright as the vessels. Without contrast, the vessels and lymph nodes look about the same density.

[@medhaithemabidi7413]

great very helpful i have a Q: lobar segmental and subsegmental, are they assesed with CT? because i coudn"t find it :/

[@ThoracicRadiology]

Usually these are not described in detail because it doesn’t change the stage of the cancer nor the management very much.

Sir,What is the meaning of few subcentrimetric sizes of lymphnodes noted In mediastinum

[@ThoracicRadiology]

One centimeter is the usual cutoff threshold for lymph nodes. If they are bigger than 1 cm, it is usually abnormal. Smaller than 1 cm usually means normal. Subcentimeter means less than 1 cm
