Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can AI Enhance PET/MRI Assessment for Extraprostatic Tumor Extension in Patients with PCa?
December 17th 2024The use of an adjunctive machine learning model led to 17 and 21 percent improvements in the AUC and sensitivity rate, respectively, for PET/MRI in diagnosing extraprostatic tumor extension in patients with primary prostate cancer.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
Mammography Study Suggests DBT-Based AI May Help Reduce Disparities with Breast Cancer Screening
December 13th 2024New research suggests that AI-powered assessment of digital breast tomosynthesis (DBT) for short-term breast cancer risk may help address racial disparities with detection and shortcomings of traditional mammography in women with dense breasts.
Can AI Facilitate Single-Phase CT Acquisition for COPD Diagnosis and Staging?
December 12th 2024The authors of a new study found that deep learning assessment of single-phase CT scans provides comparable within-one stage accuracies to multiphase CT for detecting and staging chronic obstructive pulmonary disease (COPD).
Study Shows Merits of CTA-Derived Quantitative Flow Ratio in Predicting MACE
December 11th 2024For patients with suspected or known coronary artery disease (CAD) without percutaneous coronary intervention (PCI), researchers found that those with a normal CTA-derived quantitative flow ratio (CT-QFR) had a 22 percent higher MACE-free survival rate.
Can MRI-Based AI Bolster Biopsy Decision-Making in PI-RADS 3 Cases?
December 9th 2024In patients with PI-RADS 3 lesion assessments, the combination of AI and prostate-specific antigen density (PSAD) level achieved a 78 percent sensitivity and 93 percent negative predictive value for clinically significant prostate cancer (csPCa), according to research presented at the Radiological Society of North American (RSNA) conference.
Assessing MACE Risk in Women: Can an Emerging Model with SPECT MPI Imaging Have an Impact?
December 9th 2024In research involving over 2,200 women who had SPECT MPI exams, researchers found that those who had a high score with the COronary Risk Score in WOmen (CORSWO) model had a greater than fourfold higher risk of major adverse coronary events (MACE).
Can an Emerging AI Software for DBT Help Reduce Disparities in Breast Cancer Screening?
December 5th 2024In a recent interview, Sarah Friedewald, MD, discussed new study findings for an adjunctive AI software for digital breast tomosynthesis (DBT) that revealed nearly equivalent sensitivity and specificity rates for breast cancer across a diverse cohort.
Skeletal Muscle Loss and Dementia: What Emerging MRI Research Reveals
December 4th 2024In a recent interview at the RSNA conference, Shadpour Demehri, MD and Kamyar Moradi, MD discussed new brain MRI research findings that demonstrated a link between increased dementia risk and sarcopenia with the temporalis muscle.
New Interventional Radiology Research Shows Merits of Genicular Artery Embolization for Knee OA
December 3rd 2024In a cohort of over 160 patients with knee osteoarthritis (OA), including grade 4 in nearly half of the cases, genicular artery embolization led to an 87 percent improvement in the quality of life index, according to research presented at the recent RSNA conference.
Siemens Healthineers Debuts New Photon-Counting CT Systems at RSNA
December 2nd 2024Debuting at the Radiological Society of North American (RSNA) conference, the new photon-counting computed tomography (PPCT) scanners Naeotom Alpha.Pro and Naeotom Alpha.Prime reportedly combine rapid scan times with high-resolution precision.
