Is PET/CT Better than CT for Monitoring Metastatic Breast Cancer Treatment?
April 10th 2023A recent prospective study found that progression-free survival (PFS) and disease-specific survival (DSS) were significantly associated with breast cancer tumor treatment response on 2-(18F)FDG-PET/CT imaging in comparison to contrast-enhanced computed tomography (CT), which showed no evidence of a significant association with tumor response.
Can AI Improve Triage of CT Pulmonary Angiography Exams for Acute PE?

Study Looks at Contributing Factors to Incomplete Follow-Up for BI-RADS 3 Findings
April 6th 2023Emerging research suggests that 29 percent of patients with index breast magnetic resonance imaging (MRI) exams, 45 percent of Asian women and 30 percent of women living in the highest disadvantaged neighborhoods did not have follow-up imaging after a BI-RADS 3 diagnosis.
Study Finds AI More Effective Than Sonographer Interpretation of Cardiac Function on Echocardiograms
April 5th 2023Based on a review of 3,495 echocardiographic studies to evaluate left ventricular ejection fraction (LVEF), researchers found that cardiologists changed initial artificial intelligence (AI) assessment 16.8 percent of the time and initial sonographer assessment 27.2 percent of the time.
Can ChatGPT Provide Appropriate Information on Mammography and Other Breast Cancer Screening Topics?
April 5th 2023Researchers found that ChatGPT offered appropriate responses to 22 out of 25 patient-oriented questions on mammography screening, dense breasts, BI-RADS scoring and other topics related to breast cancer screening and prevention.
New Medtronic App Streamlines MRI Screening for Patients with Cardiac Devices
April 5th 2023Offering built-in safety features and independent verification of magnetic resonance imaging (MRI) compatibility with cardiac devices such as pacemakers or implantable cardioverter defibrillator systems, the MRI Care Pathway app may enhance the efficiency of radiology workflows for MRI scans in patients with these devices.
AI-Enabled Lung Assessment Tool for Handheld Ultrasound Gets FDA Nod
April 4th 2023The artificial intelligence (AI) powered Auto B-line Counter, which reportedly produces a B-line count from a six-second ultrasound clip, may facilitate more expedient and consistent assessment of abnormal lung function.
Automated Breast Ultrasound: Is it a Viable Second-Look Option for Women with Dense Breasts?
April 4th 2023Emerging research shows the adjunctive use of automated breast ultrasound with mammography has similar sensitivity for breast cancer detection as adjunctive handheld ultrasound but may offer reduced false-positive rates in women with dense breasts.
Seven Takeaways from New Consensus Recommendations for Cardiac MRI Assessment of COVID-19
March 31st 2023Consensus recommendations from the Society for Cardiovascular Magnetic Resonance provide pertinent insights on the unique abilities of cardiac magnetic resonance imaging (MRI) to provide optimal characterization of myocardial tissue and diagnosis of COVID-19-related myocardial injuries.
Ultrasound-Based Tool May Help Differentiate Renal Fibrosis in Patients with Chronic Kidney Disease
March 30th 2023Smart-CKD, an ultrasound-derived, computer-aided diagnosis (CAD) tool, demonstrated an area under the curve of 81 percent and an 83 percent sensitivity rate in a validation cohort for differentiating between mild and moderate to severe fibrosis in patients with chronic kidney disease.
Study Finds No Impact for Deep Learning Software in PI-RADS Scoring or Diagnosis of Prostate Cancer
March 28th 2023In a recent study of a deep learning software in patients with suspected prostate cancer, researchers noted no difference in the detection of clinically significant prostate cancer nor PI-RADS scoring consistency.
What a Chest CT Study Reveals About Ground-Glass Opacities and Recurrence with Lung Adenocarcinoma
March 27th 2023In a study of over 1,000 patients who had surgery for invasive lung adenocarcinoma, researchers found that solid adenocarcinoma on pre-op CT imaging was associated with more than double the risks of recurrence and brain metastasis in patients with clinical stage I disease in comparison to ground-glass opacity (GGO) adenocarcinoma.
Study: Emerging AI Platform for DBT Shows 23 Percent Increase in Breast Cancer Detection Rate
March 23rd 2023In a recent video interview, Kathy Schilling, M.D., discussed findings from a study of ProFound AI, an adjunctive artificial intelligence (AI) software for digital breast tomosynthesis (DBT), that demonstrated a 23 percent increase in breast cancer detection in comparison to DBT alone.
What a Breast MRI Study Reveals About Axillary Lymph Nodes and COVID-19 Booster Vaccination
March 21st 2023In a study of 128 patients who had breast magnetic resonance imaging (MRI) exams after COVID-19 booster vaccination, researchers noted that nearly 19 percent of the cohort had equal to or greater than 0.2 cm of increased lymph node cortical thickness.
Could Cardiac MRI Improve Risk Stratification in Patients with Dilated Cardiomyopathy?
March 20th 2023Emerging research suggests that cardiac MRI findings of late gadolinium enhancement, native T1 values and extracellular volume fraction may predict sudden cardiac death-related events in patients with nonischemic dilated cardiomyopathy.
Looking at Next Steps to Reinforce National Breast Density Notification
March 17th 2023In a recent video interview, Amy Patel, M.D., shared her perspective on forthcoming national beast density notification in mammography reporting, emphasized the importance of educating primary care providers on breast density risks, and discussed the ongoing need for coverage of supplemental options for breast cancer screening.
Gleamer's BoneView Gains FDA Clearance for AI-Powered Pediatric Fracture Detection
March 15th 2023The artificial intelligence (AI)-enabled software, which has a documented 91 percent sensitivity rate for detecting pediatric fractures, is reportedly the first AI fracture detection modality to receive FDA 510(k) clearance for use in the pediatric population.
Seven Takeaways from Best Practice Recommendations for Incidental Radiology Findings in the ER
March 14th 2023Noting that computed tomography (CT) scans are obtained for more than 30 million emergency department (ED) patients annually and that 31.3 percent of ED CT scans reveal incidental findings, representatives from the American College of Radiology (ACR) and the American College of Emergency Physicians (ACEP) recently collaborated on best practice recommendations for addressing incidental imaging findings in EDs.
