Adenosine stress DECT equivalent to SPECT, MRI
A new power combo consisting of adenosine stress and dual-energy CT (DECT) is delivering diagnostic accuracy equivalent to stress/rest cardiac MRI and nuclear perfusion (SPECT) for detecting perfusion defects, according to research presented at the American Heart Association meeting in New Orleans.

MedCAC panel members question VC's effectiveness
Virtual colonoscopy may have been dealt a setback this week after members of a U.S. government panel expressed doubts about the technology. Panel members charged with recommending whether VC should receive Medicare reimbursement said there was incomplete evidence of VC's cost-effectiveness and overall benefit as a screening tool for colorectal cancer.

Researchers cut false positives in lung CAD
One of the thorniest challenges in computer-aided detection (CAD) is the high rate of false-positive detections, a number that generally rises in tandem with the sensitivity of the CAD algorithm. University of Tokyo researchers recently set out to develop a new false-positive reduction method based on dual classifiers for juxtapleural and nonpleural nodules.

Prior hysterectomy complicates optical colonoscopy
In a study with important implications for colon cancer screening, Pennsylvania researchers found that both female gender and prior hysterectomy were associated with failed colonoscopy. Dr. Hanna Zafar discussed the results at last week's International Symposium on Virtual Colonoscopy in Boston.

Model finds small polyp surveillance safe, cost-effective
A new model analysis concludes that surveillance of small (6- to 9-mm) colorectal polyps is both safe and cost-effective compared to immediate polypectomy, which suffers from relatively high costs, rare complications, and above all a low yield for colorectal cancer in lesions smaller than 10 mm in diameter.

Dual-energy VC makes tagged materials disappear
BOSTON - Researchers in Jerusalem are pushing the envelope with a novel dual-energy CT scanner and software combination that detects fecal residue tagged with barium and iodine, removing them from virtual colonoscopy images and making them easier to read.

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.

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.
