Does organ-specific CT dose reduction really reduce dose?
By Abraham Kim
Researchers from Belgium are questioning whether organ-based tube-current modulation in CT chest studies of women really reduces radiation dose. They found that while radiation dose to the breast fell, it increased in other areas, according to a study published on March 27 in Radiology.

AI can help distinguish lung nodules on CT scans
By Erik L. Ridley
VIENNA - Artificial intelligence (AI) offers value in characterizing nodules on CT lung cancer screening exams, possibly reducing the number of benign cases that are unnecessarily worked or followed up, according to a pair of Thursday presentations at ECR 2018.

Separating the art of medicine from artificial intelligence
By Dr. Hugh Harvey
Is it feasible to develop an artificial intelligence algorithm that can actually "read" chest x-rays? The task is definitely not an easy one and major challenges must be addressed, writes radiologist Dr. Hugh Harvey in his new column.

Why errors in radiology are no easy matter
By Philip Ward
Radiologists who make errors are not always negligent, sloppy, or careless, but a greater emphasis on training and competency as well as improvements in systems used for reporting and communication of images can reduce the number of discrepancies and clinical incidents, U.K. researchers have found.

French find no need for CT to rule out PE
By Abraham Kim
French researchers found that a set of clinical criteria was just as accurate as a protocol that included CT pulmonary angiography for ruling out pulmonary embolism (PE) in the emergency department, according to an article published in the February 13 issue of the Journal of the American Medical Association.

How often are lung nodules missed on CAC scoring scans?
By Abraham Kim
If an incidental lung nodule is present on a CT coronary artery calcium (CAC) scoring scan, how often is that nodule actually detected and worked up? Not as often as one might expect, according to researchers who analyzed the reasons why nodules might be missed in a presentation at RSNA 2017.

Lancet: Europe must get set for lung cancer screening
By Rebekah Moan
Experts from around Europe are urging the European Union (EU) to implement lung cancer screening using low-dose CT within the next 18 months. The EU position statement, published in the December issue of Lancet Oncology, recommends a risk stratification approach, among other guidelines.

Backlog of 23K unread chest x-rays draws review of Portsmouth
By Brian Casey
A backlog of 23,000 unread chest x-ray images at a U.K. National Health Service (NHS) hospital in Portsmouth has drawn the attention of the Care Quality Commission, which has ordered the facility to take immediate action to ensure the images are read promptly. The episode has also prompted the commission to review radiology reporting across the NHS network in England.
