CT lends itself to opportunistic screening for osteoporosis
August 10, 2022 -- Chest CT for indications such as lung cancer screening can also be used to screen for osteopenia or osteoporosis -- especially when an artificial intelligence (AI) algorithm that identifies regions of interest is added, a study published August 6 in Osteoporosis International suggests.

Patient with cancer receives first 3D-printed titanium jaw
August 10, 2022 -- A patient with head and neck cancer received the first 3D-printed titanium lower jaw in a successful operation, according to an August 4 press release from the Netherlands Cancer Institute. The jaw was reconstructed based on the patient's imaging. Read More

Can body composition analysis monitor NETs on CT?
August 9, 2022 -- Body composition analysis of routine PET/CT staging exams could be used to opportunistically monitor patients with neuroendocrine tumors (NETs) of a gastroenteropancreatic origin, according to research published on August 4 in Scientific Reports. Read More

NELSON lung screening protocol beats NLST for cancer detection
August 7, 2022 -- In a face-off between CT lung cancer screening trials, the protocol used to analyze lung nodules in the Dutch-Belgian Randomized Lung Cancer Screening (NELSON) trial proved more sensitive than that used in the U.S. National Lung Screening Trial (NLST). Read More

Changing CT order entry process helps cut contrast media use
August 5, 2022 -- Modifying the imaging order entry process in an electronic health record can significantly reduce the number of CT exams that require iodinated contrast agents, according to research published on August 3 in the American Journal of Roentgenology. Read More

CT screening evens out gender disparity in lung cancer mortality
August 3, 2022 -- Men with lung cancer have a much higher risk of mortality compared with women, says a new paper published August 1 in Lung Cancer. But this difference disappears if they got CT lung screening, suggesting that screening can even out gender disparities. Read More

Smaller lung airways heighten women's COPD risk
August 2, 2022 -- The fact that women tend to have narrower lung airways heightens their risk of chronic obstructive pulmonary disease (COPD) compared with male counterparts, a study published August 2 in Radiology has found. Read More

Do CT lung cancer screening rules need to be expanded again?
July 28, 2022 -- Current guidelines on CT lung cancer screening from the U.S. Preventive Services Task Force (USPSTF) may not cover many current and former smokers who remain vulnerable to developing lung disease, a study published July 28 in JAMA Oncology has found. Read More

Did new CT lung cancer screening guidelines really improve access?
July 26, 2022 -- New guidelines issued last year on who should get CT lung cancer screening nearly doubled the number of people eligible for the scans. But that doesn't necessarily mean they will get them, due to healthcare disparities, according to a study published July 24 in Cancer Medicine. Read More

Prokop predicts the next frontiers of CT technology
July 25, 2022 -- Over the past 30 years, CT technology has rapidly evolved, and it is now mature. So what are its next frontiers? Further automation and better interventional support, according to a July 13 presentation by Dr. Mathias Prokop, PhD, delivered at the ECR in Vienna. Read More
