Effect of Algorithm on CT in Patients with Blunt Abdominopelvic Trauma
An algorithm’s effect on CT use in the emergency department.
The implementation of a clinical triaging algorithm decreases the use of multidetector CT in patients who present to the ED with blunt abdominopelvic trauma (BAPT), according to a study published in Radiology.
Researchers from Boston University Medical Center in Massachusetts and Palantir Technologies, in Palo Alto, California, evaluated the effect of an institutional clinical triaging algorithm on the rate of multidetector CT utilization in BAPT.
The study included 13,096 patients who presented at an urban level I trauma center over an eight-year period with BAPT. The patients ranged in age from 15 to 95 (mean age 42). These patients were divided into two groups: those who were admitted between January 1, 2006 to June 30, 2010, before the algorithm was implemented (the prealgorithm group) and after implementation, which was from July 1, 2010 to December 31, 2013 (the postalgorithm group). Parameters were recorded from abdominopelvic CT study reports for the pre- and postalgorithm groups: number of abdominopelvic CT examinations at admission, number of abdominopelvic CT examinations with positive BAPT-related findings, injury severity score, length of hospital stay, and number of mortalities.
The results showed there was a 32.1% decrease in use of CT following implementation of the algorithm:
“The implementation of a clinical triaging algorithm resulted in decreased use of multidetector CT in patients who presented with BAPT to the emergency department,” the researchers concluded.
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.
