CT Update: FDA Changes Course on Post-ICM Thyroid Monitoring in Young ChildrenApril 28th 2023
Revising 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.
TeraRecon Launches AI-Powered Neuro SuiteApril 28th 2023
The artificial intelligence (AI)-powered Neuro Suite reportedly enables radiologists to access leading neurological AI algorithm solutions in the field, including the brain magnetic resonance imaging (MRI) segmentation capabilities of the Combinostics’ algorithm that can help differentiate degenerative pathologies such as Alzheimer’s disease and dementia.
Microvascular Invasion in Hepatocellular Carcinoma: Can a CT Radiomics Model Have an Impact?April 27th 2023
A hybrid computed tomography radiomics model demonstrated up to an 86 percent area under the curve in predicting microvascular invasion in patients with hepatocellular carcinoma in a recently published study.
Study Shows Benefits of Reduced Energy Consumption with MRI Devices and Possible Millions in Cost SavingsApril 26th 2023
Researchers suggested that overnight use of a power-save mode on outpatient magnetic resonance imaging (MRI) devices in the United States could reduce annual energy consumption by 76,288.2 megawatt hours (MWh) and add up to $10.7 million in cost savings.
New Study Assesses Cancer Risks with CT in Pediatric PatientsApril 24th 2023
While 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 2023
Lamenting 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.
Emerging AI Tool Improves Worklist Triage and CT Detection of Incidental Pulmonary EmbolismApril 21st 2023
In a new study involving over 11,700 chest computed tomography (CT) scans in oncology patients, adjunctive artificial intelligence software demonstrated a sensitivity rate of 91.6 percent for incidental pulmonary embolism (IPE) and reduced median detection and notification time for IPE-positive scans from multiple days to one hour for a radiology department at a comprehensive cancer center.
Should Race and Ethnicity Factor into Starting Ages for Mammography Screening?April 20th 2023
Emerging research looking at data from over 414,000 cases of breast cancer deaths suggests that Black women should begin annual mammography screening seven to nine years earlier than White women.
Spine Radiology Insights on Venous Fistula Localization and Finding Cerebrospinal Fluid LeaksApril 19th 2023
In a recent lecture at the American Roentgen Ray Society (ARRS) 2023 Annual Meeting, Andrew Callen, M.D., discussed a variety of imaging features associated with cerebrospinal fluid (CSF) leaks, the diagnostic utility of the Bern score as well as the merits of 3D T2FS MRI and dynamic computed tomography myelography.
Does Timing of Imaging Affect Interpretation of Contrast-Enhanced Mammography?April 19th 2023
Earlier initiation of imaging after contrast administration with contrast-enhanced mammography may provide better visibility of lesions and conspicuity against background parenchymal enhancement, according to new research presented at the American Roentgen Ray Society (ARRS) 2023 Annual Meeting in Honolulu, Hawaii.
