Scientific Paper of the Year

AI WomanStandalone AI for breast cancer detection at screening digital mammography and digital breast tomosynthesis: A systematic review and meta-analysis. Yoon, JH et al, Radiology, May 23, 2023. To learn more about this paper, click here.

The first study the Minnies expert panel picked for Scientific Paper of the Year revealed a fine line – AI algorithms are indeed valuable tools, but their performance raises the uncomfortable specter of radiologists losing their jobs.

In a study published in Radiology, a team led by Dr. Jung Hyun Yoon, PhD, from Yonsei University in Seoul, conducted a meta-analysis including over 1.1 million screening breast imaging exams that used AI software to interpret imaging. AI had a higher pooled area under the curve (AUC) than radiologists (0.87 vs. 0.81) when it comes to mammograms and DBT exams, they found.

In an accompanying editorial, Anabel Scaranelo, MD, of the University of Toronto, urged caution. She wrote that breast imaging departments will need to balance the promise of such tools for reducing fatigue and burnout with "the threat of radiologists losing their jobs to powerful algorithms."

Diagnostic imaging utilization in the emergency department: Recent trends in volume and radiology work relative value units. Poyiadji N et al, Journal of the American College of Radiology, August 3, 2023. To learn more about this paper, click here.

EmergencyThe second finalist for Scientific Paper of the Year took a deep dive into the increasing demand for advanced imaging in emergency departments. The researchers asked, "What effect is this having on radiologist work relative value units (wRVUs)?"

The answer isn't great, considering the current radiology workforce shortage, they noted.

A team led by Neo Poyiadji, MD, from Henry Ford Hospital in Detroit, analyzed emergency department imaging use volumes and wRVUs between 2014 and 2021. The results illustrated increases of 35.5% in CT volumes at their level one trauma center and a 53.7% spike in wRVUs; meanwhile, MRI volumes increased by 56.3% and wRVUs by 69.4%.

The authors speculated that many factors could play a part in these trends, including fear of malpractice litigation and the desire to bypass preauthorization requirements for advanced imaging.

Perhaps most importantly, however, they suggested that this trend will likely continue.

Best Radiology Image

The first finalist for Best Radiology Image is from research showing that photon-counting CT (PCCT) effectively detects heart disease in high-risk patients. In a study published June 20 in Radiology, lead author Muhammad Hagar, MD, from the University of Freiburg in Germany described how the modality offers "significant benefit for people previously ineligible for noninvasive screening” and could help clinicians better diagnose heart disease and tailor patient care.

“While fast PET (1-2 minutes per bed for an average of 8-10 minutes scan) has been possible since the introduction of PET/CT scanners with detectors using silicon photomultipliers, it is the recent introduction of SPECT/CT scanners with detectors using cadmium-zinc-teluride (CZT) positioned around the patients that allow for very fast image acquisitions after treatments using beta emitters such as [Lu-177],” Iagaru told “Scans acquired as fast as 4 minutes with image quality comparable to those acquired in 8 or 12 minutes will improve patient convenience and allow for documentation of treatment distribution and personalized dosimetry, particularly in clinics with high patient volumes.”
