In this series, authors of select AJR articles discuss how their studies were performed, the results, and how the studies changed their practices.
Impact Of Deep Learning Reconstruction On Image Quality And Diagnostic Performance Of Accelerated Shoulder MRI
Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.21.26577
Rosalind Gerson, PGY3 discusses a new study which shows that applying deep learning reconstruction to accelerated shoulder MRI improves image quality and decreases artifact severity to a level similar to that of standard sequences, without compromising sensitivity, specificity, and diagnostic accuracy.
Comparing Imaging Modalities in the Detection of Sporadic Primary Pheochromocytoma
Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.21.26071
Wenhui Zhou, MD, PhD reviews a recent AJR article examining the diagnostic performance of six different imaging modalities in the detection of sporadic pheochromocytoma, and the science behind several radiotracers used in the detection of pheochromocytoma. This study supports the use of 18F-FDOPA as the first-line imaging modality in the workup of suspected adrenal pheochromocytoma.
Impact of DBT and AI-CAD on mammographic surveillance after BCT
Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.21.26506
Alexandra Millet, MD discusses a new study shows that accuracy improves and recall rates decrease when DBT or AI-CAD are used as adjuncts to DM alone for surveillance of the ipsilateral and contralateral breasts in women with a personal history of breast cancer after BCT, indicating that these additional methods can reduce unnecessary callbacks. In the ipsilateral breast, addition of AI-CAD resulted in lower recall rates and higher accuracy than did the addition of DBT. This suggests that AI-CAD may help address the challenges of post-BCT surveillance mammograms.
Dual-Energy CT Derived Electron Density in the Evaluation of Lung Cancer Nodal Disease
Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.21.26208
In this episode, Gregory Lee, MD focuses on a new AJR article that focuses on how dual-energy CT derived electron density values can add accuracy in the diagnosis of lymph node metastasis in the setting of non-small cell lung cancer.
Use of Contrast Enhanced Ultrasound to Evaluate Neonatal Brain Injury
Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.21.26274
Viet Le, MD discusses the diagnostic performance of contrast-enhanced ultrasounds in evaluating neonatal brain injury while highlighting the safety and feasibility of the modality, which are important to consider in potentially critically ill patients.
Giving the Cold Shoulder to Warming CT Contrast Media?
Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.21.26256
Should CT contrast media be warmed? Currently, the ACR has not provided conclusive recommendations, and data to guide decision-making has been sparse. In this episode, John Do, MD discusses a recently published study showing that prewarming iohexol 350 may not be necessary to reduce the risk of extravasation and reaction rates.
I LOVE THESE GUYS!!!
I LOVE AJR I ALMOST HAVE EVERY SINGLE SONG
