Five-Year Study Shows Significant Overuse of CT Angiography in the ER
April 2nd 2024Researchers noted a 67.4 percent increase in head and neck CT angiography and a 38 percent reduction in findings of acute pathology in a recent comparison of 2017 and 2021 statistics for headache and/or dizziness presentations at the emergency department of an urban academic medical center.
Interventional Radiology Study Shows Low Breast Cancer Recurrence 16 Months After Cryoablation
March 29th 2024In a cohort of patients with invasive breast cancer and tumor sizes ranging between 0.3 to 9 cm, image-guided cryoablation was associated with a 10 percent recurrence rate at 16 months, according to research recently presented at the Society of Interventional Radiology (SIR) conference.
Could Virtual Non-Contrast Images from Photon-Counting CT Reduce Radiation Dosing with CCTA?
March 28th 2024Emerging research on coronary artery calcium scoring for the assessment of coronary artery disease (CAD) suggests the use of virtual non-contrast images from photon-counting CT may lead to a nearly 20 percent reduction in radiation dosing.
FDA Clears CT-Based AI Tools for PE Detection and Stroke Severity Assessment
March 26th 2024The artificial intelligence (AI) modalities CINA-iPE and CINA-ASPECTS may facilitate improved detection of incidental pulmonary embolism and stroke evaluation, respectively, based on computed tomography (CT) scans.

March 25th 2024The multimodality system nCommand Lite reportedly facilitates real-time remote imaging guidance on scanning parameters and procedure assessments to licensed technologists for a variety of imaging modalities including CT and MRI.
Female Representation in Radiology: Where Things Stand
March 25th 2024Women comprise nearly 80 percent of breast imaging departments and 45 percent of pediatric radiology departments at academic institutions, but burnout, the COVID-19 pandemic and discrimination have impeded further progress in radiology, according to a recently published literature review.
FDA Clears Mobile C-Arm Device that May Accelerate Fluoroscopic and 3D CT Imaging
March 21st 2024Offering ease of mobility and self-driving capabilities, the Ciartic Move C-arm device reportedly reduces the stress and potential for error associated with manual repositioning during intraoperative imaging with computed tomography and fluoroscopy.
Emerging Insights on MRI-Guided Transurethral Ultrasound Ablation for Prostate Cancer
March 21st 2024For men with prostate cancer, the use of MRI-guided transurethral ultrasound ablation (TULSA) led to a 92 percent decrease in median prostate volume at one year, according to new research recently presented at Society of Interventional Radiology (SIR) conference.
AI Radiology ROI Calculator Study Projects 451 Percent ROI Over Five Years
March 18th 2024Incorporating an artificial intelligence (AI) platform into the radiology workflow at a stroke management-accredited hospital may lead to projected savings of 78 days in triage time and 41 days in reporting time for radiologists over a five-year period, according to new research.
Study: PET/MRI May Prevent Up to 83 Percent of Unnecessary Biopsies in Men with PI-RADS 3 Lesions
March 15th 2024For men with PI-RADS 3 lesions, PRIMARY scores of 4-5 with PET/MRI had a sensitivity rate of 87.5 percent for clinically significant prostate cancer, according to newly published research.
What New Research Reveals About ChatGPT and Ultrasound Detection of Thyroid Nodules
March 13th 2024In a comparison of image-to-text large language models (LLMs), ChatGPT 4.0 offered a 95 percent sensitivity rate and an 83 percent AUC that were comparable to that of two senior radiologists and one junior radiologist interacting with LLM to differentiate between malignant and benign thyroid nodules on ultrasound.
Could Cloud-Based 'Progressive Loading' be a Boon for Radiology Workflows?
March 13th 2024The newly launched Progressive Loading feature, available through RamSoft’s OmegaAI software, reportedly offers radiologist rapid uploading of images that is faster than on-site networks and other cloud-based systems regardless of the network radiologists are using.
Study Says Low-Field MRI Offers Sufficient Diagnostic Quality for Detecting Spinal Pathology
March 11th 2024In a study of patients who had lumbar spine MRI exams at 0.55T, 1.5T and 3T, researchers found that 0.55T MRI provided acceptable diagnostic quality across all sequences for varying pathologies including degenerative joint disease, compression fractures and osseous metastatic disease.
Computed Tomography Insights on GI Bleeding: Nine Takeaways from New Consensus Recommendations
March 7th 2024In joint consensus recommendations issued from the Society of Abdominal Radiology and the American College of Gastroenterology, researchers discussed key pearls, benefits, and limitations of CT angiography for imaging of overt lower GI bleeding and CT enterography for detecting small bowel bleeding.
ECR Study Finds Mixed Results with AI on Breast Ultrasound
March 6th 2024While adjunctive use of AI led to significantly higher specificity and accuracy rates in detecting cancer on breast ultrasound exams in comparison to unassisted reading by breast radiologists, researchers noted that 12 of 13 BI-RADS 3 lesions upgraded by AI were ultimately benign, according to research presented at the European Congress of Radiology.
