After a multivariable assessment including age and comorbidities, women with pulmonary embolism (PE) had a 48 percent higher risk of one-year mortality than men with PE, according to a new study involving over 33,000 patients.
Study Finds Non-Contrast CT 30 Percent Less Accurate than CECT for Abdominal Pain in the ER
May 5th 2023In a study involving 201 consecutive patients presenting to emergency departments (EDs) with abdominal pain, researchers found that radiology faculty accuracy rates in interpreting non-contrast, abdominopelvic computed tomography (CT) scans ranged from 68 to 74 percent.
Microvascular Invasion in Hepatocellular Carcinoma: Can a CT Radiomics Model Have an Impact?
April 27th 2023A 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.
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.
Emerging AI Tool Improves Worklist Triage and CT Detection of Incidental Pulmonary Embolism
April 21st 2023In 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.
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).
What a Ten-Year CT Study Reveals About Emphysema and Continued Smoking
April 13th 2023Over the course of a decade, people with preexisting emphysema who continued smoking had the greatest decline in lung density, according to computed tomography (CT) findings from a study involving over 8,400 total participants and over 4,100 current smokers.
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?
April 7th 2023A recent study showed that artificial intelligence (AI)-based worklist reprioritization led to a mean reduction of 12.3 minutes in radiology report turnaround time for positive computed tomography pulmonary angiography (CTPA) exams that were positive for pulmonary embolism.
Study Finds Low Use of LDCT Among Eligible Candidates for Lung Cancer Screening
March 30th 2023A retrospective review of insurance claim data from over one million people eligible for lung cancer screening with low-dose computed tomography (LDCT) found that less than five percent were screened.
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.
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.
New Chest CT Study Assesses Impact of COVID-19 Variants and Vaccination Status
March 8th 2023Emerging research from a multicenter study found that COVID-19 vaccination was affiliated with a lower likelihood of high computed tomography (CT) severity scores and typical CT findings for COVID-19 in comparison to unvaccinated patients.
