FDA Clears AI Software for CT Detection and Triage of Obstructive Hydrocephalus
September 13th 2023Indicated for the triage and notification of obstructive hydrocephalus on non-contrast brain computed tomography (CT), the artificial intelligence (AI)-enabled software is reportedly the first radiology triage modality to obtain the Food and Drug Administration’s (FDA) Breakthrough Device Designation.
What a Large CT Study Reveals About Potential Kidney Injury, Diabetes and Risk Stratification
June 7th 2023The use of contrast-enhanced computed tomography (CECT) was associated with more than double the risk of contrast-induced acute kidney injury (CI-AKI) in patients with diabetes and an estimated glomerular filtration rate (eGFR) less than 30 mL/min/1.73 m2 in comparison to the use of non-contrast CT in this population.
CT Study Examines Post-Reperfusion Infarction Growth in Vaccine-Naive Patients with COVID-19
May 17th 2023Unvaccinated people with COVID-19 who undergo angiographic reperfusion after acute ischemic stroke may have a greater than fivefold risk of continued infarct growth in comparison to unvaccinated people without COVID-19, according to computed tomography perfusion (CTP) and magnetic resonance imaging (MRI) findings from a recently published study.
Philips Introduces AI-Enhanced CT System for High-Volume Radiology Screening Programs
May 17th 2023The artificial intelligence (AI)-enabled CT 3500 system reportedly reduces patient positioning time by 23 percent, improves low-contrast detectability by 60 percent and facilitates up to an 80 percent reduction in radiation dosing.
CT Update: FDA Changes Course on Post-ICM Thyroid Monitoring in Young Children
April 28th 2023Revising a March 2022 recommendation, the Food and Drug Administration (FDA) said thyroid monitoring for young children three years of age and under receiving iodinated contrast media (ICM) in relation to contrast-enhanced computed tomography (CECT) can now be reserved for those with risk factors including prematurity, low birth weight or conditions affecting thyroid function.
New Study Assesses Cancer Risks with CT in Pediatric Patients
April 24th 2023While one computed tomography (CT) scan appears to have no elevated cancer risk in pediatric patients, four or more pediatric exposures to CT scans are associated with increased risks for intracranial tumor, leukemia, and non-Hodgkin lymphoma, according to newly published research out of Taiwan.
Could Controlled Imaging Rein in Suboptimal Use of MRI, CT and Ultrasound Exams?
April 24th 2023Lamenting a lack of control over imaging requests from referring clinicians, this author suggests that a more collaborative approach between referrers and radiologists may facilitate more efficient use of imaging.
RapidAI Gets FDA Nod for AI Assessment of Non-Contrast CT for Acute Stroke Triage
April 18th 2023Powered by artificial intelligence (AI), the Rapid NCCT Stroke modality is reportedly the first medical device to gain FDA 510(k) clearance for detecting suspected large vessel occlusion and intracranial hemorrhage based on assessment of non-contrast computed tomography (NCCT).
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.
