CT radiation dose levels vary widely, new study finds

A new international study has found wide variation in radiation dose levels used for CT scans, potentially exposing patients to unnecessary radiation. On the positive side, dose could easily be reduced through changes in CT protocols, according to the study published January 2 in BMJ.

US screening data from Fukushima shed light on thyroid cancer in kids

The latest results of mass ultrasound screening of children for thyroid cancer after the Fukushima disaster were published online on November 29 by JAMA Otolaryngology -- Head & Neck Surgery. The study provides vital data on thyroid cancer and may lead to growing demands outside of Japan for more ultrasound scans in younger people, increasing the risk of overdiagnosis, experts have warned.

How Denmark strives for quality in breast screening

Multidisciplinary teamwork, high-volume readers, training and audits, and continuous monitoring of quality are vital in breast cancer screening, according to Dr. Ilse Vejborg, a speaker at Tuesday's RSNA 2018 session on the Nordic countries. Her group also works hard to avoid potential harms from overdiagnosis and unnecessary intervention.

Bearded men pose greater hygiene risk than dogs in MRI

Patients should not feel unduly concerned if a dog was the previous visitor to the MRI unit, but they should worry if a bearded man has just been scanned. That's the key finding of a novel Swiss-led infection study published online by European Radiology on July 30.

Could a blood test rule out most CT for brain injury?

A blood test that detects biomarkers for brain injury could help rule out patients suspected of having traumatic intracranial injuries, thus avoiding the need for CT scans, according to a large multicenter observational trial published online July 24 by Lancet Neurology.

Would risk-based breast screening be more cost-effective?

Not offering breast screening to women at lower risk of cancer could improve the cost-effectiveness of screening programs, reduce overdiagnosis, and maintain most of the benefits of screening, according to U.K. research published online July 5 by JAMA Oncology.

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.

Could AI scoring help with managing 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.

Clinicians, beware: CT diagnostic accuracy varies by adnexal lesion type
