CCTA More Positive Patient Experience Than MPI
Patients who undergo coronary CT angiography receive lower radiation doses and are more pleased with the experience than with MPI.
Coronary CT angiography (CCTA) performed on patients with acute chest pain provides lower radiation dose and yielded fewer unpleasant experiences among the patients than SPECT myocardial perfusion imaging (MPI), according to a study published in the Annals of Internal Medicine.
Researchers from Montefiore Medical Center and Albert Einstein College of Medicine in Bronx, New York, performed a randomized, controlled, comparative effectiveness trial in order to compare CCTA with conventional noninvasive testing.
A total of 400 patients with acute chest pain, mean age 57, participated in the study:
• 54% of patients were Hispanic
• 37% were African-American
• 63% were women
The results showed that the CCTA and MPI groups did not significantly differ in outcomes or resource utilization over 40 months:
“More patients in the CCTA group graded their experience favorably and would undergo the examination again,” the authors wrote.
What is the Best Use of AI in CT Lung Cancer Screening?
April 18th 2025In comparison to radiologist assessment, the use of AI to pre-screen patients with low-dose CT lung cancer screening provided a 12 percent reduction in mean interpretation time with a slight increase in specificity and a slight decrease in the recall rate, according to new research.
The Reading Room: Racial and Ethnic Minorities, Cancer Screenings, and COVID-19
November 3rd 2020In this podcast episode, Dr. Shalom Kalnicki, from Montefiore and Albert Einstein College of Medicine, discusses the disparities minority patients face with cancer screenings and what can be done to increase access during the pandemic.
Can CT-Based AI Radiomics Enhance Prediction of Recurrence-Free Survival for Non-Metastatic ccRCC?
April 14th 2025In comparison to a model based on clinicopathological risk factors, a CT radiomics-based machine learning model offered greater than a 10 percent higher AUC for predicting five-year recurrence-free survival in patients with non-metastatic clear cell renal cell carcinoma (ccRCC).
Could Lymph Node Distribution Patterns on CT Improve Staging for Colon Cancer?
April 11th 2025For patients with microsatellite instability-high colon cancer, distribution-based clinical lymph node staging (dCN) with computed tomography (CT) offered nearly double the accuracy rate of clinical lymph node staging in a recent study.
