Key MRI Findings Predictive of Treatment Response for Unresectable Hepatocellular Carcinoma
For patients with unresectable hepatocellular carcinoma, a pre-treatment MRI finding of LI-RADS tumor in vein was associated with over an 86 percent lower likelihood of responding to transcatheter arterial chemoembolization (TACE) and targeted immunotherapy.
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.
