2021 Survey Into the Adoption of AI in Radiology

The market for radiology AI solutions increased substantially in 2021, correlating to increased demand for radiology services, and a bottleneck in available physicians. AI solutions are being considered and implemented to increase efficiency, reduce staffing burdens and improve healthcare delivery.

Arterys recently conducted a study of 30 independent radiology groups, representing a variety of practice types and patients. These study participants were mostly directly involved in their radiology practices' overall IT strategy and decision-making. There were a number of notable trends, but in this article we’d like to focus on the adoption of AI in these radiology practices.

2021 Survey Into The Adoption Of AI In Radiology

Top Drivers of AI Adoption in Independent Radiology Practices

AI can transform a radiology practice. Almost 57% of respondents in our 2021 study have fully adopted an AI application into their clinical care. 

This survey shows that increased productivity and accuracy are the factors driving the integration of AI into independent radiology practices. 

AI Increases Productivity

Productivity improvement is one of the main drivers of AI adoption into radiology practice, with 27% of respondents adopting AI into their workflows for enhanced efficiency.

2021 Survey Into The Adoption Of AI In Radiology

Without AI support, many of the tasks performed by radiologists are tedious and time-consuming. As the volume of study data to review increases, radiologists need a more effective, modern user experience that streamlines complex workflows. For example, manually measuring the size of lesions or scoring images requires prolonged focus and is prone to error. 

The efficiency of existing workflows is also hindered by radiologists multi-tasking between reading images, searching for relevant clinical data, and navigating across multiple applications. The slower pace of image analysis and interpretation limits the number of patients a given radiologist can cater to and decreases overall productivity, financial reimbursement, and quality of patient care. With the integration of AI into existing PACS, radiologists can benefit from faster, more simplified and data driven workflows that streamline image interpretation and increase overall productivity.

AI Improves Accuracy

17% of survey respondents chose to adopt AI to increase the accuracy of results.  As you can see, the respondents primarily don't use AI for increased accuracy, but instead a multitude of other reasons such as increasing efficiency and automating manual tedious tasks. Medical image analysis and interpretation are subjective processes, even for the most experienced radiologists. AI algorithms can standardize aspects of these processes such that radiologists can make fast and accurate diagnostic decisions. 

Besides improvements to productivity and accuracy, survey respondents also adopted AI into their practices for reasons such as:

  • Enhanced decision making
  • Improved quality of care
  • Minimized delays
  • A better understanding of patient conditions
  • Enhanced radiological readings

Some respondent groups adopted AI into their radiology practice for more specific reasons, such as improving the detection of lung nodules or breast cancer. 

The survey's data shows greater AI adoption for larger-sized radiology groups: all respondents from radiology groups that conduct over 1 million exams per year have adopted AI into their practice. However, only 25% of groups that perform 250,000 to just under 500,000 exams per year have integrated AI into their workflows.

In contrast, 43% of independent radiology groups which have not adopted AI into their workflows mention financial constraints as the main limitation. Other reasons for not adopting AI include:

  • Need for specialized workforce
  • Limited resources to support the adoption
  • Fear that AI will cause problems

Faster Clinical Detection and Examination

Even with the transformative potential of AI, some practices have been reluctant to adopt AI into independent radiology practices. Of the 13 survey respondents who have not adopted AI into their radiology practices, 54% are not considering the option. However, 46% of respondents are actively looking into how to adopt AI into their practices, with improved disease detection and exam turn-around time as the top motivating factors. Other reasons include:

  • Capability to quality control workflows via second reads
  • Automation of basic reporting and interpretation tasks previously performed by radiologists
  • Automated 3D reconstruction and advanced visualization capabilities
  • Increased confidence in diagnostic decision making
  • Support for back-office tasks such as billing, coding, and scheduling

Integrating AI Into a Radiology Practice

How do independent radiology groups envision AI integrating into their practices?

As the AI market grows and technology advances, there remain many possibilities for radiology AI applications. However, the immediate focus for most independent radiology groups within the next five years is mainly around automation of:

  • Reporting and interpretation tasks
  • 3D construction
  • Advanced visualizations

Automation can significantly increase the bandwidth of radiologists by shortening the time spent on image interpretation. For example, radiologists spend at least 3-4 seconds per image to meet the workload demand for an eight-hour day. 

AI can help redeem that time and help radiologists address pressing patient needs. An internal study revealed that our Cardio AI product dramatically improves the rate of LV/RB function segmentation by 25 minutes, demonstrating the remarkable capability of AI to streamline diagnostic decision-making and simplify study workflows. Image analysis driven by machine learning (ML) also dramatically boosts radiologist productivity by decreasing the time spent manually analyzing images from the typical five minutes to only 20 seconds with ML support.

Another key priority for radiology groups is improved disease detection to minimize false positives, especially for complex disease conditions such as cancer.
