Enterography raises standard for diagnosing inflammatory bowel disease
Enterography is the story of progress made possible from better chemistry applied to contrast media development and the recent leaps in engineering that have revolutionized CT. This unique imaging technology is directed at the small bowel, an overlapping, undulating, 22-ft-long section of the gastrointestinal tract remotely located between the stomach and large intestine.

Raising DR tube voltage reduces dose for lumbar studies
Ignoring manufacturer guidelines for imaging equipment is usually inadvisable, but Kuwaiti researchers have found that doing so for digital radiography (DR) lumbar studies can reduce radiation exposure, according to a poster presentation at last week's American Association of Physicists in Medicine meeting.

Gold nanoparticles add cancer-killing power to radiotherapy
With a note of appreciation to Albert Einstein, medical physicists at Boston's Brigham and Women's Hospital are learning how gold nanoparticles can serve as an effective secondary source of cancer-killing electrons generated as a byproduct of the element's exposure to radiation.

QA software creates framework for assessing CT radiation risks
Initial experience with software that calculates radiation risk based on patient age, gender, and dose suggests that radiation exposure varied by as much as 50% among facilities, according to a study presented at this week's American Association of Physicists in Medicine meeting.

Market report finds strength in hospital-based CT
A new user analysis of MDCT utilization and sales trends has identified a shift in the balance of market power, which now appears to favor acute care hospitals over private-practice freestanding medical imaging centers.

Zgrav suit offers more radiation protection for fluoro studies
An interventional radiologist's quest to extend his injury-ridden career has led to a new option for radiation protection: the Zgrav suit. Early clinical trials suggest it could greatly affect how much radiation physicians absorb during fluoroscopically guided procedures.

Adding MBI to DBT finds more breast cancers
By Amerigo Allegretto
Adding molecular breast imaging (MBI) to DBT screening leads to more invasive cancers detected in women with dense breasts.
September 23, 2025
Images in a 62-year-old woman who presented for screening. (A) Image from DBT screening (the synthesized 2D mediolateral oblique view of the left breast is shown) at year on was interpreted as negative and showing heterogeneously dense breast. (B) Image from molecular breast imaging screening (mediolateral oblique view) at year one reveals a 0.9-cm non-mass focal area of uptake in the left breast (arrow). (C) Targeted ultrasound scan (transverse image) shows a suspicious mass in the 3-o’clock position of the left breast, 4 cm from the nipple. Ultrasound-guided core biopsy and lumpectomy revealed a 0.9-cm grade 2 invasive ductal carcinoma, an estrogen receptor–negative, progesterone receptor–negative, human epidermal growth factor receptor 2–negative lesion, with two sentinel nodes negative (N0).
