Clinical cases will not have patient identifying info.
Timing may be recent or years ago.
Gender, age, clinical details, diagnosis may be changed.
Respect patients always.
Cases all based on experience, but do not assume actual people or recently seen.
Thanks, @DocPNW!

Attention to #spectral images! @CtSpectral
⚠️ The endobronchial content is enhancing --> solid!
1️⃣Virtual non-contrast (VNC)= 39HU
2️⃣Conventional= 71UH (>20UH compared to VNC)
3️⃣ Iodine density =1.26 mg/ml

#12 The Many Faces of Organizing Pneumonia (OP) 🎭
1⃣ OP is a term used to describe a nonspecific response to lung injury (infection, drugs, RT, autoimmunity, cryptogenic...) 🫁
Radiological features of OP are wide: consolidation, GG, nodules & other more specific features ➡️🧵
Mimic of LV "ischemia" on CT: LV anterior/apical hypodensity from fatty metaplasia, NOT from decreased enhancement.
Easily resolved with #SpectralCT: Abnormal area is fat density on virtual non-contrast.
Small LV thrombus, much easier to see on iodine map and overlay with #SpectralCT.
Can be hard to see on echo. #radres, you may save a life when you call this on CT!

For anyone who wants to view this offline, here is a pdf copy. I took out some of the animated images, so there is a slide or two that is incomplete, but nearly complete. dropbox.com/s/8b72ij0wvfu1f5…

Excited to share that our educational exhibit on the current state of interstitial lung disease imaging was awarded a MAGNA CUM LAUDE award by @RSNA. Please come check it out. @UChicagoRADS @UCSDRadRes @ChestXrayDoc @UWiscRadiology @CURadiology @UKyRadiology @OHSURadiology
Rounded atelectasis can occur anywhere!
Indeterminate RUL lung nodule, with pleural thickening (red arrows). Oblique parasagittal recon nicely shows "comet-tail" sign.
On #SpectralCT, characteristic intense iodine uptake.
Stable on follow up for several years. #radres #FOAMed

A very informative and comprehensive review of “Multi-Energy CT of acute abdominal Emergencies” by Dr. Gopal Punjabi
@ERadSociety #ASER23 #ERad #Radiology #Radres – at San Diego, CA
Anterior column fracture of the acetabulum on 3D CT.
Classification of acetabular fractures so much easier on 3D CT.

Thank you @EsgarSociety for the Magna Cum Laude award of this #Esgar2023.
This award is not only mine but also from my colleagues Dra.Canales, Dra. Garcia Latorre and @nicoalmeidaa and great collaboration of @CtSpectral
