Patients fine with COVID-19 lung cancer screening delays
October 27, 2020 -- The majority of patients aren't concerned about delays in lung cancer screening with low-dose CT due to the COVID-19 pandemic, according to survey results published October 22 in the Journal of the American College of Radiology.  Discuss
Radiomics can aid management of lung cancer patients
October 26, 2020 -- Researchers from the H. Lee Moffitt Cancer Center and Research Institute in Tampa, FL, have reported that CT radiomics features can help predict tumor behavior in screening-detected lung cancer. They've also found that PET/CT radiomics shows promise for guiding non-small cell lung cancer treatment decisions.  Discuss
CT volume yet to rebound to pre-COVID-19 levels
October 23, 2020 -- The volume of CT studies performed in the U.S. has recovered since the early days of the COVID-19 pandemic. But as of the end of September, it was still far below pre-pandemic expectations, according to registry study data published in the Journal of the American College of Radiology.  Discuss
Canon launches CT scanner with 90-cm bore at ASTRO 2020
October 23, 2020 -- Canon Medical Systems is taking advantage of this week's American Society for Radiation Oncology (ASTRO) virtual meeting to launch Aquilion Exceed LB, a CT scanner dedicated to radiation therapy planning.

AI extracts more data from single-energy CT
October 22, 2020 -- An artificial intelligence (AI) algorithm was able to extract more data from conventional CT images, allowing single-energy CT to approach the performance of dual-energy CT without the additional radiation, according to a study published October 19 in the journal Patterns.  Discuss
Spectral CT boosts early COVID-19 assessment
October 22, 2020 -- Spectral CT is better at identifying early-stage COVID-19 disease than conventional CT, enabling better visualization of pulmonary lesions, according to a study published October 21 in the American Journal of Roentgenology.  Discuss
Lack of Medicare CTC coverage affects people of color
October 21, 2020 -- The number of screening CT colonography (CTC) exams appears to decrease after age 65 -- a trend that may have a disproportionate impact on Black patients and those of other racial minorities, according to a study published October 18 in the Journal of the American College of Radiology.  Discuss
CT shows manifestations of recreational drug use
October 19, 2020 -- CT illuminates the dangerous abdominopelvic complications caused by recreational drug use, including disseminated infections, gastrointestinal ischemia, and visceral infarction, according to a review published October 16 in RadioGraphics.  Discuss
Incidental findings on LDCT are worth working up
October 14, 2020 -- Low-dose CT (LDCT) for lung cancer screening occasionally finds other malignancies outside the lungs, according to a study published October 12 in the Journal of the American College of Radiology.  Discuss
COVID-19 outweighs radiation for death risk
October 13, 2020 -- The risk of death from COVID-19 far outweighs the risk of death from imaging exams that impart radiation such as chest x-ray or CT, according to a study published October 7 in the Journal of Radiological Protection.  Discuss
