MR elastography effective for assessing liver stiffness in children
MR elastography (MRE) is an effective technique for noninvasive monitoring of liver stiffness -- a surrogate for fibrosis -- in children and young adults with autoimmune liver disease, researchers have reported.
A team led by first author Jonathan Dillman, MD, of Cincinnati Children’s Hospital Center in Ohio found that MRE liver stiffness measurements were elevated in children and young adults with autoimmune liver disease. The results were published April 18 in the American Journal of Roentgenology.
“[As well, these measurements] were not significantly different between subsets of patients with primary sclerosing ch...

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...

Radiologist consultation improves patients' LCS attitudes
Consulting with a radiologist boosts patients' attitudes towards lung cancer screening (LCS) and their interest in quitting smoking, researchers have reported.
A team led by Alex Thomas, a medical student at the University of Chicago Pritzker School of Medicine, found that a short consultation between radiologists and patients -- during which the patient's LCS results were reviewed -- not only improved patients' understanding of the screening exam but also motivated them toward smoking cessation. The results were published April 17 in Current Problems in Diagnostic Radiology.
"LCS using LDCT is a powerful tool in the fig...

PET/MRI reveals sex differences in patients with autism
PET/MRI shows that young women with autism spectrum disorder (ASD) have increased brain metabolism associated with translocator protein (TSPO), a group from Harvard University in Boston has reported.
In a pilot study, the researchers showed that women with autism have higher uptake of carbon-11 (C-11) PBR28 radiotracer -- which binds to TSPO -- on brain PET/MRI than those without the condition. The finding adds to current scarce knowledge about molecular markers in these patients, noted lead author Chieh-En Jane Tseng, PhD, and colleagues.
“Over 90% of neuroimaging studies in ASD in the last 20 years only studied males...

Lumicell's Lumisight, LumiSytem get FDA nods
Lumicell's Lumisight (pegulicianine) optical imaging agent has been approved by a new drug application (NDA) by the U.S. Food and Drug Administration (FDA).
The FDA has also granted premarket approval for the company's LumiSystem, Lumicell's direct visualization system. Both Lumisight and LumiSystem previously received FDA Fast Track and Breakthrough Device designations.
LumiSystem allows surgeons to scan the breast cavity post-lumpectomy, in real-time, to detect and resect residual cancer that may have otherwise been missed, potentially sparing some patients from second surgeries. Its combination with Lumisight is indi...

PET tracer for gliomas under expedited review
The U.S. Food and Drug Administration (FDA) has granted fast-track designation to Telix Pharmaceuticals’ PET radiotracer F-18 floretyrosine (Pixclara) for imaging progressive or recurring gliomas.
Pixclara was developed by researchers at the University of California, San Francisco. The tracer reveals the activity of specific transporter proteins known as LAT1 and LAT2, which are highly active in brain regions with gliomas. The technique can help determine if a glioma is truly progressing or undergoing a treatment-induced change, known as pseudo-progression, where standard MRI is often inconclusive, the company said.
