Feedback helps docs adhere to CT imaging guidelines
For reducing inappropriate CT scans, clinical decision-support software is a good place to start. But the software alone isn't enough to get doctors to comply, according to a study in the American Journal of Roentgenology. The researchers found that letting doctors know their ordering patterns are being watched can help.

CCTA, SPECT MPI yield similar outcomes in chest pain
Although they provide different radiation exposure levels and patient experiences, SPECT myocardial perfusion imaging (MPI) and coronary CT angiography (CCTA) produce remarkably similar outcomes in initial imaging for chest pain, according to a new study.

CT lung screening prompts some to keep smoking
Simply talking about lung cancer screening causes smokers to think seriously about the consequences of their habit, and about quitting. But when smokers know that CT lung cancer screening is available, almost half opt to continue smoking, according to a new study in JAMA Internal Medicine.

CT dose alerts show important but limited utility
CT radiation dose alerts have their strengths and certainly their weaknesses, according to a study from Boston. But for better or worse, the alerts are mandatory under the Smart Dose (XR-29) rules that took effect last month. So radiologists must comply -- while still looking for ways to improve the new standard.

AAOS: Some radiation during pregnancy is acceptable
Doctors must heed basic precautions when using imaging to diagnose traumatic injury in pregnant women, but diagnostic imaging scans are safe when used properly, according to a new report in the Journal of the American Academy of Orthopaedic Surgeons.

Data from CTC scans improve osteoporosis screening
Data from CT colonography (CTC) scans can be used for a comprehensive assessment of bone strength and bone mineral density, according to the results of a study in Radiology. The new technology goes beyond what's provided by dual-energy x-ray absorptiometry and could improve clinicians' ability to assess fracture risk.

Sports-related head injuries spur avalanche of CT scans
Emergency department admissions for sports-related head injuries have skyrocketed in recent years -- and so have unnecessary CT scans to evaluate them, according to a new report in the American Journal of Emergency Medicine.

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.
