Radiologists build radiation dose registry just for kids

With all eyes on pediatric radiation dose these days, researchers from six children's hospitals in the U.S. are collaborating to build the first pediatric CT dose index registry. The group is beginning with a study to set pediatric abdominal CT diagnostic reference dose levels based on patient size.

FDA targets vendors in push to trim pediatric radiation dose

The U.S. Food and Drug Administration has raised the ante in its drive to reduce pediatric radiation dose, launching a new program that will require manufacturers to consider the safety of children when designing new x-ray imaging devices. Devices that do not comply with the program may have to carry warning labels advising against their use in children.

Low-dose CT's bright future, troubled present

The task at hand in CT radiation dose reduction is pretty straightforward: Record the dose, establish best practices for using it, and then use the right dose for every scan. But in reality these goals are so complex as to be nearly impossible, said Dr. R. Paul Guillerman of Texas Children's Hospital in Houston.

Antioxidant formula halves DNA damage from CT

A new study in Radiology has found that ingesting a commercially available combination of antioxidants reduces DNA damage by more than half compared to results obtained without antioxidant protection after irradiation with doses comparable to a CT angiography exam.

Stroke victims not receiving timely imaging

"Time is brain" in stroke care -- and far too much of both are being lost, according to a neurologist-led study in Stroke that documents the delays most patients are experiencing in many hospitals before the critical step of brain imaging occurs.

CT doses are lower in dedicated pediatric radiology departments

Radiation exposure from CT was significantly lower when abdominal scans were performed in a dedicated pediatric radiology department compared to scans performed in a department serving both children and adults, researchers report in this month's Journal of the American College of Radiology.

ARRS: CT radiation far less risky than underlying disease

The long-term risk of future cancers associated with CT scans has been under scrutiny for years, but those risks aren't remotely as serious as the risk of dying from the diseases CT is used to diagnose, concluded a study presented on Tuesday at the American Roentgen Ray Society (ARRS) meeting in Vancouver.

3D MRI technique helps plan treatment for pediatric heart conditions

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
