Radiation debate revisited

The debate over the health effects of radiation continues to grab headlines in radiology. This week in our X-Ray Digital Community we’re reporting on a U.S. initiative to evaluate the addition of x-rays to the list of known human carcinogens.

CAD helps solve CT lung screening dilemma

CT lung cancer screening may sound like a great idea, but the reality of nodule detection is nettlesome. The target population is huge, the scans are tedious to read, and screening studies can produce boatloads of suspicious nodules, all of which must be followed up in a systematic fashion.

Cardiac MRI: An ER triage tool?

Could cardiac MRI become a first-line triage tool for patients presenting to the emergency room with chest pain? Researchers from the National Institutes of Health say cardiac MRI is both sensitive and specific in detecting acute coronary syndrome in such patients.

Are fears of low-level radiation overblown?

Radiation dose tops the agenda this week on AuntMinnie.com. We’re featuring a pair of articles on the topic, one of which challenges the conventional wisdom that radiation dose at any level is harmful to humans.

Rads rankled by MGH plan to send scans to India

Should radiology images acquired in the U.S. be sent to overseas locations for primary interpretation? The question has been simmering for years, but boiled over when Massachusetts General Hospital announced a plan to set up a primary-read center in India to view inpatient exams.

RSNA show bounces back in 2002

If one had to find a theme for the 2002 Radiological Society of North America meeting, Return to Normalcy might be a good one. All but gone were concerns over terrorism that clouded the 2001 conference and led to a double-digit decline in attendance that year, especially among international visitors.

Offsite archive shows worth as PACS backup solution

So you’ve shelled out the money for a PACS. And you’re starting to reap the benefits with improved workflow, better service for your referring physicians, and lower film costs. But a big problem remains: What’s the best way to back up your data?

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
