Jordan Perchik, MD discusses a new study in which a team of radiologists attempt to detail imaging findings that can identify patients with interstitial lung disease who are at high risk of developing acute exacerbation after thoracic surgery. Several promising metrics are described however the close overlap between the statistically significant values leads to a broader discussion of statistical significance versus practical application.

Performance of MRI for Detection of Lateral Meniscus Posterior Root Injury in Children with Anterior Cruciate Ligament Tear Apr 22, 2021

Yoon-Jin Kim, MD discusses a study identifying imaging findings of lateral meniscus posterior root tear on pre-operative MRI in children. Imaging findings generally having a high specificity put low sensitivity with tears of the root proper having the best accuracy for identifying root tears when arthroscopy reports are used at the reference standard.

For patients who have undergone prior lumpectomy for localized breast cancer, no clear guidelines exist regarding use of diagnostic or screening mammography for post-lumpectomy imaging surveillance. Amber Liles, MD, MPH dives into a recently published article which seeks to answer this research question.

Evaluating the MRI characteristics and frequency of Displaced Flap Tears of the Triangular Fibrocartilage Complex Apr 06, 2021

Show notes

Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.25437

The triangular fibrocartilage complex is a structure which is often associated with ulnar sided wrist pain. Injuries to this structure can result in displaced tears which have a characteristic appearance. Shrey Patel, MD discusses a new AJR article that describes characteristic MRI findings and the frequency of this injury.

Y-90 Radioembolization for the Treatment of Metastatic Colorectal Cancer – Does Primary Tumor Location Prognosticate Survival? Mar 16, 2021

Show notes

Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.25315

Giuseppe V. Toia, MD reviews a retrospective study exploring prognostic factors for patients with chemorefractory metastatic colorectal cancer treated with Y-90 radioembolization. The study emphasizes primary tumor location as a predictor of overall survival.

In-Bore Versus Fusion MRI-Targeted Prostate Biopsy of PI-RADS Category 4 or 5 Lesions: A Retrospective Comparative Analysis Using Propensity Score Weighting Mar 16, 2021

Show notes

Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.25207

Shrav Sridhar MD, discusses a retrospective study in which target-specific prostate cancer detection rate in a cohort of patients who underwent in-bore MRI biopsy was compared to the rate in a cohort of patients who underwent ultrasound-MRI fusion-guided biopsy.

In-Gantry MRI-Guided Prostate Biopsy: Finding a Sweet Spot in Lesion Sampling Mar 16, 2021

Show notes

Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.24918

Frederic J. Bertino, MD discusses a recent AJR article that investigates how to optimize the cores samples for in-gantry prostate MRI biopsy. It is suggested by this retrospective study that three cores from the dominant lesion achieves the "sweet spot" in balancing significant cancer detection and reducing anesthesia and procedure time. Study limitations and future directions are discussed.

Can We Reliably Utilize Ultrasound to Evaluate Fatty Liver? Mar 04, 2021

Show notes

Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.24874

Pei-Kang Wei, MD and Cinthia Cruz-Romero, MD discuss the importance of ultrasound as a reliable and affordable method to evaluate fatty liver and the applicability of ultrasound to evaluate fatty liver in various patient populations, both in children and adult.
