ACR releases updated imaging criteria
According to itn, the American College of Radiology (ACR) has updated its ACR Appropriateness Criteria (ACR AC), which consists of 233 diagnostic imaging and interventional radiology topics covering over 3,000 clinical scenarios.
The update includes nine new topics and revises nine existing ones, providing essential guidance for referring physicians and healthcare providers in making appropriate imaging and treatment decisions for various clinical conditions.
Additionally, Spanish translations of these criteria are now available for over forty topics—with more translations in progress, as part of the ACR’s ongoing efforts to make this resource more accessible.
AI-powered innovation revolutionises CT brain imaging
A new method developed by the University of Gothenburg, presented in a study in the journal Alzheimer’s & Dementia, can provide diagnostic support by enhancing the information obtained from computed tomography (CT) brain images, making them comparable to magnetic resonance imaging (MRI) results.
Using deep learning and artificial intelligence, the software transfers interpretations from MRI images to CT images of the same brains—allowing for improved diagnostics in primary care and reducing the number of false negatives.
The simple and quick method shows promise for applications in dementia diagnosis and other areas of neuroradiology—including normal pressure hydrocephalus (NPH) diagnosis and treatment monitoring.
MRI predicts radiation side effects in prostate cancer
A recent study by Corewell Health suggests that men with longer prostatic urethras may have a higher risk of experiencing moderate to chronic urinary side effects following radiation treatment for prostate cancer.
The study, published in Academic Radiology, found that for every 1-centimeter increase in prostatic urethra length observed on MRIs, patients were about 60% more likely to experience urinary issues.
This novel MRI metric may provide valuable insights into the risk of developing these symptoms, helping patients make informed treatment decisions and allowing doctors to explore ways to minimise side effects.
It emphasises the significance of using MRI technology in prostate cancer care for risk assessment.
MRI biomarker for Early Onset Alzheimer’s Disease found
The last but not least radiology trend, a study led by neuroscientists at Massachusetts General Hospital and published in The Journal of the Alzheimer’s Association has identified a signature MRI biomarker for Early Onset Alzheimer’s Disease (EOAD).
This biomarker, found through quantitative brain atrophy analysis in MRI scans, was validated across two independent cohorts.
It not only accurately distinguished EOAD patients from healthy controls but also correlated with symptom severity and cognitive function—demonstrating its clinical validity.
Future research will explore changes in EOAD patients’ brains over time and the relationship between atrophy within the EOAD signature and cognitive impairments in various domains. This promising finding can contribute to improved diagnosis and understanding of EOAD.
