CTA is vital to determining whether an extremity mangled in trauma can be salvaged. Do you know what to look for and report?   And electronic stimulators- do you know them when you see them?  Drs. Frederick and Gibbs summarize important articles from the current issue and recent archives. Roles of Trauma CT and CTA in Salvaging the Threatened or Mangled Extremity. Dreizin et al.

In this podcast, Ross Frederick provides an algorithmic approach to diagnosing spinal cord signal abnormality.  And Wende Gibbs reviews evaluation of thoracic outlet syndrome. Great topics for residents studying for boards and practicing radiologists! Diagnostic Approach to Intrinsic Abnormality of Spinal Cord Signal Intensity. Lee et al. RadioGraphics 2019; 39:1824–1839.  Imaging of the Patient with Thoracic Outlet Syndrome. Raptis et al. RadioGraphics 2016; 36:984–1000. 

Lesions of the chest wall- these can be hard to figure out, especially when incidental.  Dr. Frederick summarizes a new paper that simplifies narrowing the diagnosis and providing management recommendations.  Also in this podcast, Dr. Gibbs provides an update on imaging of Covid, in the acute phase and in patients who have recovered from the disease. Diagnostic and Imaging Approaches to Chest Wall Lesions. Mansour et al.  RadioGraphics 2022; 42. Chest CT in COVID-19: What the Radiologist Needs to Know. Kwee and Kwee.

CAR-T immunotherapy- an amazing advance in oncology with high rates of remission, but most patients have complications.  In this podcast we describe the science of CAR-T, physiologic timeline, and imaging features of adverse events which are common.  All radiologists should be aware in order to better help our patients with cancer.  Also, CNS Lupus- increasing in prevalence and still with high mortality.  Learn more about the myriad imaging findings associated with this illness.

Ota et al. RadioGraphics 2022; 42:212–232.

In our first podcast of 2022, we learn about a life-threatening entity that is more common that we thought, and important for radiologists in all specialties to recognize:  Spontaneous Coronary Artery Dissection.  Also, pearls and pitfalls for distinguishing malignant, benign, and incidental findings on FDG PET/CT. Spontaneous Coronary Artery Dissection: An Underdiagnosed Clinical Entity—A Primer for Cardiac Imagers. Aslam et al. RadioGraphics 2021; 41:1897–1915.  Common Skeletal Neoplasms and Nonneoplastic Lesions at 18F-FDG PET/CT. Cheung et al. RadioGraphics 2022; 42:250–267.

ECMO is an important, last resort to save many of our patients with cardiopulmonary failure and we are seeing it used in our sickest COVID patients.  Do you know how it works?  Imaging plays a vital role in assessing the complications of ECMO, but the hemodynamic alterations and artifacts make CTA tricky.  Dr. Ross Frederick summarizes this new ECMO paper and additional information on how to do it right. CT Angiography of Venoarterial Extracorporeal Membrane Oxygenation. Shen et al. RadioGraphics 2022; 42. 

This week on the Radiographics podcast, Informatics editors Drs. Juluru and Wang summarize recent papers on Natural language processing and Deep Learning.  Bag-of-Words Technique in Natural Language Processing: A Primer for Radiologists. Juluru et al. RadioGraphics 2021; 41:1420–1426. Deep Learning: An Update for Radiologists. Cheng et al. RadioGraphics 2021; 41:1427–1445.

In this podcast, Ross Frederick describes a promising new interventional radiology treatment for an extremely common source of morbidity around the world:  knee osteoarthritis.  And Wende Gibbs summarizes a multisystem paper describing the ever growing number of treatment related complications we might encounter in our cancer patients- we must be familiar with the possibilities to get them the best possible care!
