A Michigan hospital was able to reduce its backlog of screening mammograms and speed up report turnaround time through a series of steps that included batched workflow and elimination of paper forms. Researchers describe their work in a new paper in Current Problems in Diagnostic Radiology.
Mammography screening has always been a big challenge for breast radiologists, who typically read hundreds of normal mammograms before encountering an actual breast cancer.
- These challenges have only gotten worse with rising exam volumes and the well-documented shortage of radiologists, a combination that can lead to growing backlogs and longer report turnaround times.
At the University of Michigan Health System, turnaround times for mammography reports had ballooned to 8.3 days, prompting researchers to investigate ways to make the breast imaging service more efficient.
Study authors identified three main areas that slowed mammography TAT …
- Interruptions during radiologist reading shifts.
- Paper-based workflow.
- Cumbersome report dictation workflow.
So they developed a program called “Uninterrupted with Assistant” that eliminated the facility’s traditional reading model – eight-hour reading shifts in which radiologists were also responsible for other tasks like breast MRI and interventional procedures.
- Instead, they implemented four-hour shifts where radiologists batch-read mammograms without interruption. They were also aided by a clerical staff member as a “live transcriptionist” who reviewed charts and drafted pre-dictated reports in real time.
The mammography service also ditched its paper workflow in favor of having patients complete intake forms on tablets, while technologists entered data on computers.
- Finally, they updated their reporting to a standard template with pre-populated fields, based on FDA- and MQSA-approved verbiage.
They then tested the Uninterrupted with Assistant program over 32 weeks in 2021, finding that during the program …
- Mean report turnaround time fell 39% (51 vs. 83 hours).
- The institution’s TAT goal of less than 72 hours was achieved more often (93% vs. 35%).
- Radiologists experienced fewer distractions (2.0 vs. 5.6 on a 10-point scale).
The Takeaway
Batch reading isn’t new (neither is mammography worklist software), but combining the two with a ride-along assistant in the reading room creates a powerful productivity package. The Michigan model is an experience that can be emulated by other mammography centers struggling to improve efficiency and clear their backlog.

- Long-Term SCOT-HEART Supports CCTA: The landmark SCOT-HEART study in 2015 proved the value of coronary CT angiography for managing patients with stable chest pain. Last week, The Lancet published 10-year follow-up data showing CCTA’s value persists over the long term. In a study of 4.1k patients, those who got CCTA had lower odds ratio for coronary heart disease death or non-fatal myocardial infarction (OR=0.79), as well as for major adverse cardiovascular events (OR=0.80). The data further support use of CCTA for guiding preventive therapy.
- The Toll of Heart Disease: Meanwhile, a report released this week by the American Heart Association in Circulation documents the continued toll of heart disease, which kills more Americans than any other cause. In 2022 there were 942k cardiovascular disease-related deaths, up 10k from 2021, while the overall death rate per 100k people fell slightly (224 vs. 233). Cardiovascular deaths appear to be leveling out after a “major uptick” during the COVID-19 pandemic.
- Ariz. Couple Charged in ‘Full Body’ Scheme: U.S. government officials charged an Arizona couple with running an allegedly fraudulent full-body scanning business based on ultrasound scanners they said they modified with “smart chip technology” to diagnose a wide range of conditions. Investigators claim that Mary and Fred Blakley offered the scans through Blakley Clinics and then prescribed their patients supplements, creams, and veterinary products for conditions they said they discovered. They face a maximum of 165 years in prison.
- Visage Lands $21M Kentucky Deal: Visage Imaging has landed another big PACS installation deal. The company signed a nine-year contract valued at $20.6M to install its cloud-based Visage 7 enterprise imaging platform at University of Kentucky HealthCare. The agreement complements recent big Visage contracts at Duly Health and Care, Trinity Health, and NYU Langone Health.
- Radiology ‘Maestros’ Manage Surges: Researchers from Children’s Hospital of Philadelphia shared their experiences with a system to meet surges in demand for pediatric imaging. One pediatric radiologist was designated as a “maestro” with authority to recruit additional volunteer radiologists for two-hour “ad hoc shifts” during times of high study volumes. Over a year, the shifts were activated 35 times, with a volunteer radiologist failing to show only four times (11%). Authors hope the system can improve clinician well-being.
- Ikonopedia Partners with Dolbey: Ikonopedia signed a partnership with Dolbey and Company to add Dolbey’s Fusion Narrate speech recognition and automation technology to its structured reporting system. The collaboration enables physicians using both Fusion Narrate and Ikonopedia to navigate, dictate, and complete breast reports without using a keyboard or mouse, speeding up mammography reporting workflow.
- Aidoc Partners with AWS: Aidoc announced a collaboration with Amazon Web Services for AI foundation models that includes what the companies are calling a “significant investment” from AWS over multiple years. The companies will optimize Aidoc’s CARE Foundation Model – which was trained on massive datasets – to develop new algorithms for detecting critical conditions across multiple medical imaging modalities. Aidoc will expand CARE with new upgrades and work with AWS to secure FDA clearance for new applications.
- DirectMed Buys Richardson Tubes Group: Medical components firm DirectMed Imaging has acquired Richardson Healthcare from Richardson Electronics in an agreement that expands DirectMed’s CT tube business. Richardson Healthcare had focused on CT tubes for Canon/Toshiba scanners.
- Median Raises Funds: French AI developer Median Technologies is raising funds in preparation to commercialize its CT-based eyonis lung cancer screening software in the U.S. and European Union. The company secured a new loan for up to $39M and an equity line for up to $10.5M, to be used to secure FDA and CE Mark approvals. The company also took steps to decrease its cash burn rate and extend its cash runway into Q4 2025, and is seeking a U.S. commercialization partner among several leading AI companies.
- U.K. Provides Details on AI Investment: NHS officials are sharing additional details about the health system’s next framework agreement for acquiring healthcare AI. NHS framework agreements are purchasing vehicles for acquiring new technology, and current AI frameworks are expiring in September 2025. NHS hopes to consolidate separate AI frameworks into one comprehensive program called Healthcare Artificial Intelligence Solutions that’s split into six segments, or “lots,” covering different aspects of AI use. The framework reportedly covers £150M ($185M) in purchasing.
- GE Lands $247M U.K. Contract: Meanwhile, GE HealthCare landed a massive contract worth £200M ($247M) to supply medical imaging equipment to Nuffield Health in the U.K. Under the 20-year managed equipment services agreement, GE will handle equipment acquisition, installation, maintenance, and staff training at the health network. Over 800 pieces of equipment are expected to be delivered over the life of the agreement, with 100 devices scheduled for delivery in 2025 alone. GE and Nuffield have been collaborating since signing a multivendor service contract in 2017.
- PET Tracer Given Fast-Track Status: Another PET tracer in development was granted fast-track review status by the FDA. Australian radiopharmaceutical developer Clarity Pharmaceuticals is developing Cu-64 SAR-bisPSMA for imaging PSMA-positive prostate cancer lesions in patients with biochemical recurrence. Clarity said the tracer’s advantages include bisPSMA’s bivalent structure and copper-64’s longer half-life than agents based on fluorine-18 or gallium-68. Clarity is planning the phase III AMPLIFY pivotal trial to support its application for FDA approval.
- Eye-Tracking Software for Radiologists: We don’t totally understand how researchers performed this study, but it sounds super cool: Researchers used eye-tracking software while radiologists interpreted chest X-rays to assess how differences in their visual search strategies affected their diagnostic performance in detecting lung cancer. The authors then applied a machine learning algorithm to the eye-tracking data that was able to determine which radiologists were more experienced – and thus had higher accuracy. The technique was 6.9% more accurate than traditional measures in assessing experience level.
