January 20, 2021 -- The COVID-19 pandemic had an immediate impact on total CT procedure volume in the U.S. in 2020, with procedure volume projected to be 20% lower than in 2019. That's according to a new report by market research firm IMV Medical Information Division.  Discuss
Radiomics, AI can guide NSCLC treatment decisions
January 15, 2021 -- Radiomics and artificial intelligence (AI) can be used to guide treatment of non-small cell lung cancer (NSCLC) without the need for a biopsy, according to research presented January 13 at the American Association for Cancer Research Virtual Special Conference on Artificial Intelligence, Diagnosis, and Imaging.  Discuss
CT radiomics classifies small nodules found in CT lung screening
January 15, 2021 -- A machine-learning algorithm can be highly accurate for classifying very small lung nodules found in low-dose CT lung screening programs, according to a poster presentation at this week's American Association for Cancer Research Virtual Special Conference on Artificial Intelligence, Diagnosis, and Imaging.  Discuss
How many cancers were missed during the COVID-19 pandemic?
January 14, 2021 -- Cancer diagnoses declined by double digits at a prominent Boston healthcare system during the early stages of the COVID-19 pandemic in spring 2020, according to an analysis published on January 14 in JAMA Oncology. Researchers estimated more than 1,400 lesions could have been missed in a three-month period.  Discuss
Better chest CT CAC reporting avoids unnecessary exams
January 13, 2021 -- Reporting coronary artery calcium (CAC) on routine chest CT could help clinicians more accurately predict a patient's cardiovascular disease risk and avoid unnecessary additional gated calcium score CT exams, according to a study published in the January-February issue of Current Problems in Diagnostic Radiology.  Discuss
Lung involvement portends COVID-19 mortality risk
January 8, 2021 -- Volumetric analysis of lung consolidation on chest CT scans can be used to predict the risk of COVID-19 patients dying in the hospital and aid in management decisions, researchers from Michigan reported in a study published online January 6 in European Journal of Radiology Open.  Discuss
CT/ultrasound fusion enhances ovarian biopsies
January 8, 2021 -- A method that combines CT radiomics and real-time CT/ultrasound image fusion can yield more accurate and efficient tissue biopsies in ovarian cancer patients and may, in the future, even facilitate "virtual" biopsies, according to research published online December 14 in European Radiology.  Discuss
CT helps radiologists plan facial feminization surgery
January 7, 2021 -- Using CT, radiologists can play a key role in planning facial feminization surgery -- procedures that adjust masculine characteristics such as brow, nose, and chin prominence -- in transgender patients, according to a review published online December 30 in the American Journal of Roentgeonology.  Discuss
AI predicts metastasis in gastric cancer patients
January 7, 2021 -- An artificial intelligence (AI) algorithm can predict the presence of occult peritoneal metastasis in gastric cancer patients based on preoperative CT scans, potentially helping in treatment decision-making and avoiding unnecessary surgeries, according to research published online January 5 in JAMA Network Open.  Discuss
CTPA shows promise as a PE predictor in COPD patients
January 5, 2021 -- Ten percent of patients with chronic obstructive pulmonary disease (COPD) who presented at the hospital with worsening respiratory symptoms and suspected pulmonary embolism (PE) proved to have the condition on CT pulmonary angiography (CTPA), according to a study published January 5 in JAMA.  Discuss
