great review, succinct and exceptionally well demonstrated on multiplanar views. thx!
thanks Brian!
nice and friendly lecture
fabulous.
thanks for that great video.
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.
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.
@@ThoracicRadiology thanks for helping out fellow dr in understanding
Beautiful video, wonderfully explained, made it so easy to comprehend along with the precise definitions of the stations by IASLC 👍
Thank you, glad it was helpful
Very informative video
Very informative...
Top! Thank you very much. Greetings from Sicily
Thank you too!
Very nice lecture..thanks alot..keep go on
Excellent
love your class sir really excellent.. i don't have words to describe
Nicest Mediastinal LN review..awesome
Great Video; super helpful. Do you by any chance know any good practice questions to re-enforce the material?
Great
Great video! Comes in super handy for a PG-2 Rad Res. Do you have articles like that but for abdominal node stations?
Great video, Dr. Agrawal. What screen casting application and audio equipment do you use to make your lectures? Keep up the great content.
Using QuickTime for the Mac to capture the video and audio. Using an Audio Technica microphone hooked up to my Mac via USB.
I would need to understand how to see ANTERIOR MEDIASTINUM masses in a Thoracic CT...Thank you
V good 👍
great very helpful i have a Q:
lobar segmental and subsegmental, are they assesed with CT? because i coudn"t find it :/
Usually these are not described in detail because it doesn’t change the stage of the cancer nor the management very much.
I need ask what's reactive slightly mediastinal lymphadenopathy? I was diagnosed with them, I am worried? Help would be appreciated
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.
How to measure lymph node what axis we should measure the long or short
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 :)
Great question, yes you can see those too but we call them something different. Like if they are under the pectoralis then subpectoral nodes.
Thank you! I have a problem determining chest lymph nodes without iv contrast😣
You'll master it soon. Takes a little time, that's all.
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.
Good question, the lymph node map is not updated on the same cycle as TNM staging, so yes it is still current.
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.
Good luck to the team of physicians and consultants in endocrinoligy dental gynae and gastroentrogy and medical nano technology team looking into my care. From kathelizjenruddy
👏👏
Is a "non-specific borderline prominent" subcarinal lymph node (1cm) something to worry about?
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.
Sir,What is the meaning of few subcentrimetric sizes of lymphnodes noted In mediastinum
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
@@ThoracicRadiology thank you sir.much appreciate
Sir which book is considered good to read thoracic radiology for residents?
try Webb thoracic imaging
Can you see supracavicular nodes in a chest and neck ct without contrast???
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.
Hi doctor. Are normal size mediastinal lymph node usually seen on ct scan of chest? Or only the abnormal one seen?
Hi, yes, normal size lymph nodes are seen on CT scan of the chest.
@@ThoracicRadiology thanks Doctor
Sorry for asking 1 more question. If you found a patient with chest ct and there is 0.7 size paratracheal node, and the lung itself is normal. Do you think he need a repeated Ct?
@@rendhyardian58 Prob not, but that's with limited info. What does the radiologist recommend?
The radiologist did not recommend anything. Just said that there is a lymph node seen. The lung and others also normal
what is mean hypermetabolic ap window in Petscan
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.
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.
Colon or large intestine ulcers can be seen in ct scan?
CT scan of the chest? Not usually, no.
sir plz help in ct scan report impression- few small neck nodes(?significance)
Hi, I'm not sure. It could mean a lot of things. What else was seen on the CT? Did the report make any recommendations?
@@ThoracicRadiology no recommendation written in ct.
thank sir
Hi, it is probably ok, but every patient is different and you should speak to your doctor about it.
Hi Rishi.. Can ypu pls explain this ultra sound report comment..
"Multiple upto 37 x 13.5 mm sized porta peri pancreatic enlarged lymph nodes"
What could it be.. I am very scared
Hi, better to ask your personal physician who knows more about your medical history. good luck.
@@ThoracicRadiology yes..thank you
So lymph nodes do not enhance after IV contrast?
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.

Liiiiike
You are magnificent
Thank you!
Great
