Study Shows Enhanced Diagnosis of Coronary Artery Stenosis with Photon-Counting CTA
In a new study comparing standard resolution and ultra-high resolution modes for patients undergoing coronary CTA with photon-counting detector CT, researchers found that segment-level sensitivity and accuracy rates for diagnosing coronary artery stenosis were consistently > 89.6 percent.
FDA Expands Approval of MRI-Guided Ultrasound Treatment for Patients with Parkinson’s Disease
For patients with advanced Parkinson’s disease, the expanded FDA approval of the Exablate Neuro platform allows for the use of MRI-guided focused ultrasound in performing staged bilateral pallidothalamic tractotomy.
New PET Study Links Higher Education Level to Speed of Tau Accumulation with Alzheimer’s Disease
For patients with amyloid β (Aβ)-positive findings on positron emission tomography, higher educational attainment was associated with accelerated accumulation and spread of tau, according to new research.
Mammography Study: AI Facilitates Greater Accuracy and Longer Fixation Time on Suspicious Areas
While noting no differences in sensitivity, specificity or reading time with adjunctive AI for mammography screening, the authors of a new study noted a 4 percent higher AUC and increased fixation time on lesion regions.
In external testing, a model combining radiological complete response on breast MRI, nodal status and Ki-67 proliferation index yielded an 88 percent AUC for predicting pathologic complete response to neoadjuvant chemoimmunotherapy for patients with triple-negative breast cancer, according to new research.
For people with dilated cardiomyopathy and those with initially normal cardiac MRI, each 1 ug/m3 increase in one-year exposure to ambient fine particulate matter with 2.5-um > aerodynamic diameter was associated with significantly more diffuse myocardial fibrosis, according to a recent study.
