Japanese study finds VC useful for wide range of indications

New research on virtual colonoscopy from Japan found the technique to be helpful in diagnosing even patients without colorectal cancer and polyps, and it was especially useful for those with contraindications to conventional colonoscopy, according to a study in the Japanese Journal of Radiology.

Rectal surgery platform more efficient for large polyps

A new rectal surgery technique may do a better job than colonoscopy for removing large rectal polyps. A hybrid between transanal endoscopic microsurgery and single-port laparoscopy, the system can remove polyps of any size, even obstructing lesions, with less pain and scarring.

Joint Commission issues alert on medical radiation

The U.S. Joint Commission has issued an alert on the dangers of medical radiation, sending an unmistakable signal that radiology has entered its sights in a formal way. The announcement is a sign that imaging facilities will need to pay more attention to formalizing their procedures for protecting patients from unnecessary radiation dose.

64-slice CT speeds diagnosis in multiple-casualty setting

It may seem intuitive enough that 64-detector-row CT is faster for multiple-casualty trauma than four-detector-row machines, but minutes make a big difference when patients are seriously injured, according to researchers of a new study in the September issue of the American Journal of Roentgenology.

Researchers cut CT dose for nodule follow-up

For surveillance of previously detected lung nodules, CT radiation dose can be cut to approximately 3% of the original exam dose, concludes a new study in the September edition of the American Journal of Roentgenology.

Coronary calcium scores are best for guiding statin therapy

Coronary artery calcium scores generated by CT scans were far more predictive of future cardiac events than elevated high-sensitivity C-reactive protein levels, according to a new study in the Lancet that further clarifies which patients will benefit most from statin therapy.

NEJM: Radiology suits are uncommon, payouts below average

Radiologists are dragged into court less often than some other specialists -- and less often than they may think. According to a 14-year New England Journal of Medicine study, radiologists' chances of being hit with a malpractice suit and the resulting payouts were both slightly lower than for other physicians.

CTA becomes a one-stop shop with FFR measurement

Using CT to measure cardiac fractional flow reserve (FFR) is a potential game changer that could turn everyday coronary CT angiography (CTA) scans into a one-stop cardiac assessment tool, taking over some imaging tasks from other modalities.

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
