AI stroke software differences don't affect thrombectomy eligibility
Although two commercially available AI software applications can yield different volume estimations on stroke CT perfusion (CTP) studies, the differences aren't significant enough to affect patient eligibility for thrombectomy, researchers reported in an article published May 2 in the Journal of Stroke Cerebrovascular Diseases. However, there are still important issues to be aware of.
In a study involving 362 stroke cases, researchers led by first author Benjamin Alwood, MD, in the department of vascular neurology at the University of Florida in Jacksonville, and colleagues, compared core and penumbra volumes estimated by...

Jury still out on clinical use of ChatGPT
ChatGPT has been effective in 84% of radiology research studies, yet it is still too soon to confirm its complete proficiency for clinical applications, according to a team at the University of California, Los Angeles.
A group led by Pedram Keshavarz, MD, performed a systematic literature review and found that 37 out of 44 (84.1%) radiology studies show ChatGPT's effectiveness, yet none suggested its unsupervised use in clinical practice.
“Although ChatGPT seems to have the potential to revolutionize radiology, it is too soon to confirm its complete proficiency and accuracy,” the group wrote in a study published Apri...

FDA approves Lutathera for some pediatric patients
The U.S. Food and Drug Administration (FDA) has approved Novartis' Lutathera (lutetium-177 [Lu-177]) DOTATATE radiopharmaceutical for treatment of pediatric patients who are 12 years old and older with somatostatin receptor (SSTR)-positive gastroentropancreatic neuroendocrine tumors (GEP-NETs).
The April 30 approval covers foregut, midgut, and hindgut tumors and follows the same indication for adults the FDA approved in 2018, according to the FDA.
Approval was based on pharmacokinetic, dosimetry, and safety data from NETTER-P, an ongoing, international, multicenter, open-label, single-arm study of Lu-177 DOTATATE in adol...

Volumetric CT helps predict lung-lobectomy complications
Volumetric CT imaging analysis shows promise for helping clinicians determine pre- and postoperative lung function in lung cancer patients undergoing pulmonary lobectomy, researchers have found.
A team led by Zhifu Xu, PhD, of ZhangJiaKou First Hospital in Hebei, China, reported that the technique may also help predict postsurgery complication occurrence. The results were published April 30 in BMC Medical Imaging.
"[We found that] lung function detected from CT volumetric analysis [is] consistent with those from the lung function measurements in lung cancer patients … [suggesting that] CT volumetric imaging can be a fu...

AI brings scoliosis monitoring on x-rays into modern era
In this study, the authors aimed to leverage AI to improve these methods by training a convolutional neural network (CNN) model to automatically measure femorotibial length on x-ray images from a racially diverse set of pediatric patients.
The study data included 1,874 examinations from 523 pediatric patients aged 0 to 21 who underwent at least two slot-scanning radiographs in routine clinical care. Forty percent of the patients self-identified as white and not Hispanic or Latino and 60% self-identified as belonging to a different racial or ethnic group, the authors noted.The lower extremity measurement pipeline is illust...

USPSTF finalizes breast cancer screening recommendations
The U.S. Preventive Services Task Force (USPSTF)’s newly published final recommendations support breast cancer screening beginning in women at age 40, but they don’t go as far as many screening advocates had hoped.
In addition to recommending biennial breast cancer screening for women ages 40 to 74, the task force stuck with its draft recommendations from 2023, reporting that it found insufficient evidence for screening women 75 and older. What’s more, the USPSTF concluded that there was insufficient evidence to recommend supplemental screening with MRI or ultrasound in women, regardless of breast density.In announ...

Risk of knee osteoarthritis may depend on muscle mass
This study provides evidence for future tailored physical activity recommendations based on a person’s muscle mass and osteoarthritis risk,” noted lead author Yahong Wu, MD, and colleagues.
During weight-bearing activities such as running, knees are subject to the impact of several times the body's weight. Such pressure can lead to joint overloading and trigger early osteoarthritis, the authors explained. Yet it is unclear whether the effects of physical activity on knee osteoarthritis depends on the muscle surrounding the knee joint, they noted.
To explore these connections, the researchers studied knee x-rays at ba...
