Study: Photon-Counting CT Improves Accuracy of Coronary Stenosis Assessment
February 20th 2024The use of ultrahigh spatial resolution with photon-counting CT led to lower Coronary Artery Disease Reporting and Data System (CAD-RADS) category assessments in over 54 percent of patients in comparison to the use of standard spatial resolution, according to recently published research.
Study Offers Closer Look at Patient Preference For CT Angiography Over Invasive Coronary Angiography
February 19th 2024Patients who had CT angiography procedures reported lower pain levels, better preparation and were 25 percent more willing to undergo the procedure again in comparison to patients who had invasive coronary angiography, according to newly published research.
FDA Clears AI Software for Liver Attenuation on Abdominal CT
February 13th 2024The AI-enabled HealthFLD software demonstrated a 77.8 percent sensitivity rate and a 93.2 percent specificity rate for diagnosing moderate hepatic steatosis on contrast-enhanced CT scans in a recent study of over 2,900 patients.
FDA Clears AI Software for Assessing Intracerebral Hemorrhage on Non-Contrast CT
February 12th 2024Facilitating timely diagnosis and intervention for brain bleeds, the artificial intelligence (AI)-powered Viz ICH Plus software may provide quantified assessment for intracranial hyperdensities, lateral ventricles and midline shifts.
Can Multimodality AI Enhance CT Detection of Medium Vessel Occlusions?
February 8th 2024The use of multiple artificial intelligence (AI) modalities to assess blood vessel density reduction and computed tomography perfusion (CTP) mismatch values facilitated a 93.3 percent detection rate for medium vessel occlusions, according to research presented recently at the International Stroke Conference.
What Emerging CT Research Reveals About Pure Ground Glass Nodules
February 7th 2024In a computed tomography (CT) study assessing over 450 patients who had lung adenocarcinoma resection, researchers noted zero recurrence at five years and 97.7 percent recurrence-free survival at seven years for patients with resected pure ground glass nodules.
New Research Assesses Key CT Signs for Predicting Bowel Necrosis
February 7th 2024Demonstrating an 81 percent AUC, 99 percent specificity and a 98 percent positive predictive value, increased attenuation of intestinal contents was one of four CT findings deemed to be an independent predictive factor for bowel necrosis in patients with closed-loop small bowel obstruction.
Photon Counting CT May Facilitate Earlier Diagnosis of Spontaneous Intracranial Hypotension
February 5th 2024In a comparative study of energy-integrating detector CT myelography versus photon-counting detector CT (PCD-CT) myelography for the detection of cerebrospinal fluid-venous fistulas (CVFs) in cases of spontaneous intracranial hypotension, PCD-CT myelography demonstrated 10 to 19 percent higher sensitivity rates with reviewing radiologists.
Study: Deep Learning Reconstruction Reduces Effective Dosing for CT Colonography by 83 Percent
January 31st 2024Researchers found the use of deep learning reconstruction for computed tomography colonography (CTC) led to 25 percent higher subjective image quality scoring than iterative image reconstruction at a substantially reduced rate of radiation dosing.
