Is Photon Counting CT a Better Option than Dual-Energy CT for Pulmonary Angiography?
Performing computed tomography pulmonary angiography (CTPA) with a high-pitch photon counting detector (PCD) offers enhanced signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) at a reduced radiation dose in comparison to employing an energy-integrating detector (EID), according to new research.
Do Bone Scans Over Stage Prostate Cancer? What a Multicenter Study Reveals
Fifty-seven percent of patients with prostate cancer diagnosed with osseous metastases on bone scans had negative findings on PSMA PET imaging, according to findings from an international multicenter comparative study.
New Dual-Source CT Device May be Cost-Effective Alternative for Smaller Facilities
Offering a combination of simplified and personalized scanning for patients at significantly lower lifecycle costs than other dual-source CT systems, the Somatom Pro.Pulse may be a viable option for smaller rural facilities and outpatient imaging centers.
Samsung Debuts New Ultrasound Modality Geared Toward Women's Health and Urology
Combining enhanced imaging capabilities, workflow efficiencies and artificial intelligence (AI)-enabled technology to improve the diagnosis and management of health conditions in women, Samsung has launched the V6 ultrasound system.
Study Says Contrast-Enhanced Mammography Offers Comparable Breast Cancer Detection to MRI
In findings from an enriched cohort of asymptomatic patients with screening-detected abnormalities, researchers found that contrast-enhanced mammography (CEM) was superior to conventional mammography and offered equivalent detection of breast cancer in comparison to breast MRI and abbreviated breast MRI.
Adjunctive Brain Volume Quantification Tool for MRI Gets FDA Clearance
Providing automated brain volume calculations based on MRI images, NeuroShield’s artificial intelligence (AI)-powered technology may help facilitate treatment for neurodegenerative conditions ranging from Alzheimer’s disease to epilepsy.
Is Surveillance Imaging Necessary After Primary Radiation for Head and Neck Cancer?
For patients who had a complete metabolic response to radiation treatment for head and neck cancer, the authors of a recent study found that surveillance imaging with PET/CT, MRI or CT did not improve outcomes in comparison to expectant management.
Study Says MRI Offers Most Cost-Effective Imaging for Dizziness Presentations in the ER
Noting that initial imaging sensitivity is a key factor in cost-effectiveness for patients who do not require acute treatment for dizziness, researchers found that specialized MRI (including multiplanar high-resolution DWI) provided the most benefit in a comparative trial of neuroimaging modalities.
What a New Review Reveals About Mammography-Based AI and Breast Cancer Risk Assessment
Mammography-based artificial intelligence (AI) models demonstrated an 11 percent higher median AUC for predicting breast cancer than traditional clinical risk factors, according to a new systematic review of 16 retrospective studies.
Outpatient Reimbursement to Increase 65 Percent for EchoGo Heart Failure Platform in 2024
Reimbursement for use of the artificial intelligence (AI)-powered EchoGo Heart Failure platform in hospital outpatient settings for Medicare and Medicaid patients is expected to increase from $99.81 to $284.88 in 2024.
Assessing 20-year follow-up data from a cohort for an international study of annual low-dose CT screening for lung cancer, researchers noted an 81 percent survival rate after an initial primary lung cancer diagnosis for over 1,200 patients with a median 43 pack-year smoking history.
Study Links PTSD to Higher Carotid Atherosclerosis and White Matter Hyperintensity in Midlife Women
Ultrasound and MRI findings from a new study suggest that greater carotid atherosclerosis and elevated white matter hyperintensities among women with the APOEe4 genotype, a strong risk factor for Alzheimer’s disease, are associated with increased PTSD symptoms in midlife women.
