(Press-News.org) OAK BROOK, Ill. – The results of a large survey from a diverse patient population revealed cautious support for artificial intelligence (AI) implementation in screening mammography, according to a study published today in Radiology: Imaging Cancer, a journal of the Radiological Society of North America (RSNA). Personal medical history and sociodemographic factors influenced respondent’s level of trust in AI.
While the diagnostic accuracy of AI systems has drastically improved in recent years, there is still a lack of widespread adoption and acceptance of this technology for a variety of reasons, such as concerns with data privacy, algorithmic bias or even level of knowledge of AI.
One opinion that is frequently overlooked in the conversation surrounding the growth of AI in radiology is that of the patient.
“Patient perspectives are crucial because successful AI implementation in medical imaging depends on trust and acceptance from those we aim to serve,” said study author Basak E. Dogan, M.D., clinical professor of radiology and director of breast imaging research at the University of Texas Southwestern Medical Center in Dallas. “If patients are hesitant or skeptical about AI’s role in their care, this could impact screening adherence and, consequently, overall health care outcomes.”
To gain a better understanding of patient opinions and concerns regarding the use of AI in screening mammography, Dr. Dogan and colleagues developed a 29-question survey to be offered to all patients who attended their institution for a breast cancer screening mammogram. The optional survey was available for a period of seven months in 2023.
All survey questions were closed-ended and assessed the participants’ knowledge and perceptions of AI. The survey obtained demographic information in addition to clinical information, which uncovered a respondent’s history with breast cancer, such as whether they had any abnormal mammograms in the past or if they or a close family member has ever had breast cancer.
Of the 518 patients who completed the survey, most indicated support for the use of AI alongside a radiologist’s review, with 71% of respondents preferring AI to be used as a second reader. This was despite concerns about loss of personal interaction with the radiologist, data privacy, lack of transparency and bias. Less than 5% were comfortable with AI alone interpreting their screening mammogram.
Because of its large and diverse patient population, the survey uncovered a variety of demographic factors that influence patient perceptions. Respondents with more than a college degree or a higher self-reported knowledge of AI were two times more likely to accept AI involvement in their screening mammogram.
Of note, Hispanic and non-Hispanic Black respondents reported significantly higher concerns about AI bias and data privacy, which most likely resulted in a lower acceptance of AI among these patient groups.
“These results suggest that demographic factors play a complex role in shaping patient trust and perceptions of AI in breast imaging,” Dr. Dogan added.
Familial and personal medical history also impacted patient attitudes toward AI.
Regardless of whether an abnormality was detected by AI or a radiologist, patients who had a close relative diagnosed with breast cancer were more likely to request additional reviews. However, these patients exhibited a high degree of trust in both AI and radiologist reviews when the mammogram came back as normal.
In contrast, patients with a history of an abnormal mammogram were more likely to pursue diagnostic follow-up if AI and radiologist reviews conflicted. This was especially the case if it was AI that flagged an abnormality.
“This highlights how personal medical history influences trust in AI and radiologists differently, emphasizing the need for personalized AI integration strategies in mammographic screening,” Dr. Dogan said.
The researchers noted that it is important to continue engaging with patients to understand their evolving views of AI technology in health care, as the technology continues to advance.
“Our study shows that trust in AI is highly individualized, influenced by factors such as prior medical experiences, education and racial background,” Dr. Dogan said. “Incorporating patient perspectives into AI implementation strategies ensures that these technologies improve and not hinder patient care, fostering trust and adherence to imaging reports and recommendations.”

When the immune system does not function properly, individuals become more susceptible to infections caused by viruses, bacteria, or fungi. Researchers from Radboud university medical center have demonstrated that an existing drug can revive immune cells that are not functioning correctly. These findings provide leads for further research in patients admitted to the intensive care unit (ICU) with sepsis.
Twenty percent of global deaths are associated with sepsis, and it is the leading cause of death in ICUs. Sepsis is characterized by organ failure, for instance of the kidneys or lungs, caused by a dysregulated immune response to an infection. Patients with ...
Over the last couple of decades, many people have regained hearing functionality with the most successful neurotech device to date: the cochlear implant. But for those whose cochlear nerve is too damaged for a standard cochlear implant, a promising alternative is an auditory brainstem implant (ABI). Unfortunately, current ABIs are rigid implants that do not allow for good tissue contact. As a result, doctors commonly switch off a majority of the electrodes due to unwanted side effects such as dizziness or facial twitching—leading most ...
Proteins form the structural and functional backbone of the cell, and any perturbation in their synthesis can disrupt normal cellular functions. The DNA blueprint is carefully read, transcribed, and translated into functional proteins through a tightly regulated process. The ‘ribosome’ plays a crucial role in orchestrating the translation of the messenger RNA transcript by assembling amino acids into the corresponding polypeptide sequence. Ribosomal functions beyond protein synthesis have been uncovered over the years, revealing its role ...

An international research team led by Mayukh Kumar Ray, Mingxuan Fu, and Satoru Nakatsuji from the University of Tokyo, along with Collin Broholm from Johns Hopkins University, has discovered the anomalous Hall effect in a collinear antiferromagnet. More strikingly, the anomalous Hall effect emerges from a non-Fermi liquid state, in which electrons do not interact according to conventional models. The discovery not only challenges the textbook framework for interpreting the anomalous Hall effect but also widens the range of antiferromagnets ...
The use of generative AI for diagnostics has attracted attention in the medical field and many research papers have been published on this topic. However, because the evaluation criteria were different for each study, a comprehensive analysis was needed to determine the extent AI could be used in actual medical settings and what advantages it featured in comparison to doctors.
A research group led by Dr. Hirotaka Takita and Associate Professor Daiju Ueda at Osaka Metropolitan University’s Graduate School of Medicine conducted a meta-analysis of generative AI’s diagnostic capabilities using 83 research papers published between June ...

In 1638, an earthquake in what is now New Hampshire had Plymouth, Massachusetts colonists stumbling from the strong shaking and water sloshing out of the pots used by Native Americans to cook a midday meal along the St. Lawrence River, according to contemporaneous reports.
When Roger Williams, founder of the Rhode Island colony, talked with local Native Americans, he reported that the younger tribe members were surprised by the earthquake. But older tribe members said they had felt similar shaking four times in the past 80 years.
In his talk at the Seismological ...
Sediment cores drawn from four lakes in Guatemala record the distinct direction that ground shaking traveled during a 1976 magnitude 7.5 earthquake that devastated the country, according to researchers at the Seismological Society of America’s Annual Meeting.
The earthquake, which killed more than 23,000 people and left about 1.5 million people homeless, took place along the Motagua Fault, at the boundary between the North American and Caribbean tectonic plate boundary.
Severe ground shaking from the 1976 earthquake caused landslides ...
