ARRS: Use of CT angiography surges for carotid imaging
May 7, 2019 -- HONOLULU - The utilization rates of all imaging modalities for noninvasive carotid imaging have declined over the past decade with one exception -- CT angiography (CTA). CTA use for carotid imaging has grown by nearly 700%, according to a presentation on Monday at the American Roentgen Ray Society (ARRS) meeting. Read More
CT lung screening isn't reaching areas that need it most
May 3, 2019 -- The availability of CT lung cancer screening facilities favors U.S. regions that have relatively fewer individuals at risk of lung cancer. This suboptimal distribution may be contributing to the slow adoption of screening among eligible smokers, according to an article published in the May issue of Chest. Read More
Why are doctors overriding CT guidelines for PE patients?
May 1, 2019 -- As much as 37% of CT pulmonary angiography exams for patients with a pulmonary embolism (PE) were ordered against guideline recommendations at a New York hospital, according to a new study. Researchers investigated the underlying reason for this discordance in an April 30 article published in the Journal of the American College of Radiology. Read More
Lung cancer rates rise in China after screening starts
April 30, 2019 -- The incidence rate of lung cancer began climbing in women not long after CT lung screening began in China, but lung cancer mortality rates have yet to fall. And no effect has been seen yet in men, according to an article published in the June issue of Lung Cancer. Read More
Doctors continue to forgo CT lung screening discussions
April 25, 2019 -- The low rate of patient-physician discussions about CT lung cancer screening appears to be sinking lower still. New data show that less than 9% of doctors talked about screening with their patients who currently smoke, according to an article published online April 25 in Cancer Epidemiology, Biomarkers & Prevention.

AI predicts lung cancer survival from CT scan data
April 22, 2019 -- Harvard researchers have developed an artificial intelligence (AI) algorithm capable of analyzing routine CT scans to predict how well lung cancer patients will respond to treatment, as well as their likelihood of survival, according to an article published online April 22 in Clinical Cancer Research.

Can videos convince smokers to get CT lung screening?
April 19, 2019 -- Smokers who watched a video and read a brochure on the potential harms and benefits of CT lung cancer screening had a better understanding of the exam and had more confidence in their decision to get screened, according to an article published online April 17 in the Annals of the American Thoracic Society.

CTC offers added value to colon cancer screening
April 16, 2019 -- CT colonography (CTC) nearly matched the predictive accuracy of colonoscopy for colorectal cancer screening, while also allowing for risk stratification by providing detailed insight into the nature of colorectal findings in a new study, published online April 11 in the American Journal of Roentgenology.

3D-bioprinted model mimics real human heart properties
April 16, 2019 -- Researchers from Israel have created a 3D-printed model that captures the immunological, biochemical, cellular, and anatomical properties of a real human heart, according to an article published online April 15 in Advanced Science. Read More
Prolonged CT lung screening offers cumulative benefits
April 15, 2019 -- The latest results from the Multicentric Italian Lung Detection trial highlighted the increasing benefits of CT lung screening over time -- starting after year five -- culminating in a 39% reduction in lung cancer mortality risk for eligible smokers at 10 years, according to a recent study published in the Annals of Oncology.
