ET Tubes on Chest X-ray

Quick tutorial on how to evaluate ET tubes on chest radiography.

The Diaphragm on the Lateral CXR

Here are the 5 ways to distinguish which side of the diaphragm is which on the lateral CXR: 1. The stomach bubble and splenic flexure of the colon are below the left. 2. The right hemidiaphragm is usually higher than the left. 3. The left hemidiaphragm is obscured by the heart anteriorly. 4. The right hemidiaphragm terminates posteriorly by the larger right ribs., 5. Look for pathology.

How I Read a Chest CT

This is for first year residents, starting out on their chest rotation. This is the order in which I read a chest CT. When you first start out, it is important to stick to a script so that you read studies the same way each time. It may be beneficial to have a checklist that you follow to make sure you aren't missing anything.

Lobar and Segmental Lung Anatomy on CT

How to find the lobar and segmental bronchi on axial CT. This video is meant for radiology residents, but would benefit thoracic surgery residents and pulmonary medicine fellows as well.

The Secondary Pulmonary Lobule

Short description of the anatomy of the secondary pulmonary lobule. Check out this article for more information on this topic: https://www.ncbi.nlm.nih.gov/pubmed/16543587

Algorithmic Approach to Multiple Lung Nodules

Great article: https://www.ncbi.nlm.nih.gov/pubmed/16537886

Chronic Consolidation

Acute consolidation has a pretty short differential. When a consolidation becomes chronic, you have to widen your differential. This video will help you form a short but powerful differential for a chronic consolidation with the mnemonic SPACE-V. Here are my references which I highly recommend you check out: https://pubmed.ncbi.nlm.nih.gov/31200867/ https://pubmed.ncbi.nlm.nih.gov/18716117/ https://pubmed.ncbi.nlm.nih.gov/17495282/ https://pubmed.ncbi.nlm.nih.gov/20413748/ https://www.flickr.com/photos/pulmonary_pathology/

4 Must-Know Features of ILD

Here are 4 findings you have to recognize and classify to understand ILD. Ground glass opacity Reticulation Traction Bronchiectasis Honeycombing Here's the link to the Fleischner Glossary: https://pubs.rsna.org/doi/10.1148/radiol.2462070712

Subsolid Nodules

This is a description of subsolid nodules, what they are and why we treat them differently from solid nodules. Here are some of the references I used in this article: The revised lung adenocarcinoma classification—an imaging guide https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4209391/ CT screening for lung cancer: frequency and significance of part-solid and nonsolid nodules https://www.ajronline.org/doi/full/10.2214/ajr.178.5.1781053 Guidelines for Management of Incidental Pulmonary Nodules Detected on CT Images: From the Fleischner Society 2017 https://pubs.rsna.org/doi/10.1148/radiol.2017161659 LungRADS 1.1 https://www.acr.org/-/media/ACR/Files/RADS/Lung-RADS/LungRADSAssessmentCategoriesv1-1.pdf=la=en

CT signs of right heart strain with PE

This video goes over the CT signs of right heart strain that can be seen with acute pulmonary embolism. I describe and show examples of RV enlargement, septal bowing/flattening, pulmonary artery enlargement, and reflux of contrast into the IVC.

Upper Lung Predominant Fibrosis

Here's my differential for upper lung predominant pulmonary fibrosis: SHORTI: Sarcoid Hypersensitivity pneumonitis (chronic) Occupational pneumoconioses (silicosis, coal worker's, berylliosis) Radiation fibrosis TB and fungus Idiopathic pleuroparenchymal fibroelastosis
