ChatGPT performs poorly on ACR exam for residents
ChatGPT-4 received a score of 58% on an exam by the American College of Radiology (ACR) used to assess the skills of diagnostic and interventional radiology residents, according to a study published April 22 in Academic Radiology.
A team at Stony Brook University in Stony Brook, NY, prompted ChatGPT-4 to answer 106 questions on the ACR’s Diagnostic Radiology In-Training (DXIT) exam, with its performance underscoring both the chatbot’s potential and risks as a diagnostic tool, noted lead author David Payne, MD, and colleagues.
“While minimally prompted GPT-4 was seen to make many impressive observations and diagnose...

SPECT/CT predicts foot amputations in diabetics
Technetium-99m (Tc-99m) white blood cell SPECT/CT imaging may be useful for identifying diabetic patients at risk of amputations due to foot infections, according to a study published April 22 in Scientific Reports.
Researchers at Soonchunhyang University in Seoul, South Korea, found that patients were more likely to undergo amputations when they had high Tc-99m-labeled white blood cell activity at infection sites compared to patients with lower activity. The marker could help identify which patients need more aggressive interventions to avoid amputations, the group suggested.
“There is no efficient imaging tool establ...

Clinical practice LCS program finds more disease than NLST
Over a five-year period, a clinical practice lung cancer screening program at Duke University Medical Center in Durham, NC, found more disease than did the National Lung Screening Trial (NLST), researchers have reported.
The program showed a higher rate of lung cancer compared to the NLST’s, at 3.4% versus 2.4%. It also found more stage IV disease, wrote a team led by Kyle Lafata, PhD. The results were published April 23 in the Journal of the American College of Radiology.
“As LCS uptake increases, monitoring and tracking screening outcomes in clinical practice settings is key to high-quality screening and success,...

Radiologists can take steps toward environmental sustainability
Radiology departments can take proactive steps to promote environmental sustainability, according to an article published April 23 in Radiology.
A team led by Kate Hanneman, MD, of the University of Toronto in Ontario, Canada, proposed ways that departments can strategize to promote planetary health beyond turning imaging machines off when not in use. These include forming sustainability teams, opting for low-energy imaging tests when possible, and working with imaging vendors, among others.
“There are other opportunities to improve environmental sustainability that are beyond energy,” Hanneman told AuntMinnie.com. ...

Exo launches cardiac, lung AI apps for Exo Iris
Exo’s cardiac and lung AI applications are now available on Exo Iris, its handheld ultrasound device.
The company released Exo Iris last year. The point-of-care-ultrasound (POCUS) device now features pulsed-wave Doppler capabilities to offer physicians more opportunities to assess blood velocity and thus support diagnosis and deeper findings in cardiac, abdominal, and vascular applications, according to the firm.
Exo has U.S. Food and Drug Administration (FDA) 510k clearances for cardiac, lung, bladder, hip, and thyroid applications, and plans to double the number of clearances by 2025, it said. (Source: AuntMinnie.com Headlines)

Deep-learning algorithm improves liver fibrosis diagnosis
An algorithm combining the Fibrosis-4 Index (FIB-4) and an ultrasound deep-learning model could improve diagnostic accuracy and referral management for all-cause advanced liver fibrosis, a study published April 23 in Radiology found.
Researchers led by Li-Da Chen, PhD, from the First Affiliated Hospital of Sun Yat-sen University in Guangzhou, China found that their combined sequential algorithm improved specificity by over 20% for predicting pathologically advanced liver fibrosis compared with the Fibrosis-4 Index (FIB-4) alone. Additionally, the algorithm reduced unnecessary referrals by 42% without requiring access to l...

NLP uncovers racial bias in documenting ob/gyn imaging findings
Natural language processing (NLP), a form of AI, can uncover racial bias in documenting radiology-confirmed ob/gyn findings, a study published April 21 in Clinical Imaging reported.
Researchers led by Shoshana Haberman, MD, PhD, from the Maimonides Medical Center in Brooklyn, NY, found that NLP-derived data incorporated into a platform for ultrasound or MRI-confirmed uterine fibroids during pregnancy showed that Black patients were more likely to have an obstetrical diagnosis entered late into their patient charts or have missing documentation of the diagnosis.

PET/CT superior to MRI for detecting spinal bone metastases
Gallium-68 (Ga-68) DOTATATE PET/CT appears to be the best approach for detecting spinal bone metastases in patients with certain neuroendocrine tumors, according to researchers at the National Institutes of Health (NIH) in Bethesda, MD.
In a study of patients with pheochromocytomas and paragangliomas (PPGLs), the group found the approach was superior to F-18 FDG-PET/CT, MRI of the spine, whole-body CT, and whole-body MRI. The finding is significant regarding efforts to prevent serious complications in these patients, noted lead author Abhishek Jha, MD, and colleagues.

CT cerebral angiography makes emergency department (ED) diagnosis of headache more effective, researchers have found.
A team led by Dustin Mark, MD, of Kaiser Permanente Medical Center in Oakland, CA, reported that use of the technique was associated with “fewer lumbar punctures and higher detection of unruptured intracranial aneurysms, with no significant change in missed diagnoses of subarachnoid hemorrhage or bacterial meningitis.” The results were published April 19 in JAMA Network Open.
The investigators conducted a study that included data from 198,109 encounters at 21 emergency departments that involved the us...
