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.
“All providers should be committed to quality documentati...

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.
“Bone metastases weaken and destroy skeletal tissue...

Novel risk prediction model improves LCS uptake
A novel risk prediction model used in the Ontario Lung Cancer Screening Pilot increased the uptake of lung cancer screening among eligible Canadians, researchers have found.
A team led by Martin C. Tammemägi, PhD, of Brock University in St. Catharines, Ontario, reported that use of the model translated to an adherence rate to annual recall and early surveillance scans and clinical investigations of more than 85%. The findings were published April 19 in Nature Medicine.
Lung cancer is the leading cause of cancer death around the world, and research has shown that low-dose CT (LDCT) lung cancer screening of high-risk indi...

CT cerebral angiography ED headache diagnosis more effective
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...

Neuroimaging detects blast exposure brain injuries in U.S. soldiers
A battery of MRI and PET neuroimaging tests show patterns of brain injury in active-duty U.S. soldiers caused by repeated blast exposures, according to a study published April 22 in Proceedings of the National Academy of Sciences.
The findings may guide the design of a new diagnostic test for personnel exposed to blasts in training and combat, noted lead author Natalie Gilmore, PhD, of Harvard Medical School in Boston, and colleagues.
“[Special Operations Forces] personnel may experience cognitive, physical, and psychological symptoms for which the cause is never identified, and they may continue to be exposed to blast...

What's brewing in RT and RA legislation, policy, and standards?
A range of federal and state legislation and other developments in the works could have a significant impact on radiologic technologists and registered radiology assistants, either supporting and strengthening these professions or weakening them.
For example, the American Society of Radiologic Technologists (ASRT) is working with lawmakers to reintroduce the federal Medicare Access to Radiology Care Act (MARCA) in the current legislative session. Last introduced in June 2021 as HR-3657 and companion SB-2641, MARCA would amend Medicare reimbursement policy for radiologist assistants (RAs) to align reimbursement with st...

Mobile health screening model lowers costs, promotes sustainability
A new cancer screening service model developed by Italian researchers can reduce direct non-medical costs and improve environmental sustainability for breast cancer screening and other screening exams.
The investigators, led by doctoral candidate Vera Benedetto from the Health Science Interdisciplinary Center in Pisa, found that their model, which utilizes mobile cancer screening for breast, cervical, and colorectal cancer, reduced costs by over 95,000 euros ($101,155 U.S.) in terms of travel costs and productivity losses. It also reduced as much as 35 tons of carbon dioxide (CO2)-equivalent travel emissions for a popula...

FDA clears Philips Zenition 30 mobile C-arm
Philips parent Royal Philips has secured clearance from the U.S. Food and Drug Administration (FDA) for its Zenition 30 mobile C-arm.
Zenition 30 offers greater control over C-arm positioning during surgical procedures, with pushbuttons on the flat detector that allow clinicians to unlock and adjust the arm’s horizontal, orbital, and rotational positioning, the company said. It also features Philips’ MetalSmart software, which automatically adjusts image contrast and brightness to improve image quality and eliminate blooming while maintaining a low radiation dose, according to the firm.
Philips first introduced the...

Can ChatGPT ‘data mine’ patient reports for stroke registries?
ChatGPT-4 appears useful for extracting details from reports on thrombectomy procedures in stroke patients, a labor-intensive and error-prone task currently performed by human readers, according to a group in Germany.
Such “data mining” by ChatGPT could provide an alternative to manual methods for building stroke registries, with the data being key to improving the quality of stroke care, noted lead author Nils Lehnen, MD, of University Hospital Bonn, and colleagues.
“Procedural details of mechanical thrombectomy in patients with ischemic stroke are predictors of clinical outcome and are collected for prospective s...

High breast density tied to impaired recurrence-free cancer survival
This study may lead to insights on risk factors related to tumor biology, mammographic patterns at diagnosis, and breast cancer recurrence, which in turn could be used to tailor surveillance,” the Lång team wrote.
Surveillance programs post-breast cancer treatment have become more important as reports indicate the number of women living with breast cancer is rising. The researchers highlighted that identifying links between mammographic features and recurrence could help design follow-up strategies. This could lead to earlier detection of recurrence.
Lång and colleagues analyzed associations between mammographic feat...
