Same-day VC prep works, but some preps are better than others
Fecal tagging and reduced bowel preparation with iodinated oral contrast agents feasibly can be performed on the same day as a virtual colonoscopy exam, according to a new study from Italy presented at this month's RSNA meeting.

New CT method measures airway calcium to predict lung cancer
In a special "hot topic" presentation at the 2008 RSNA meeting, Ricardo Avila from software developer Kitware said that the presence of calcification at airway bifurcations in CT images can potentially predict lung cancer presence in smokers and former smokers. His company is developing software to exploit the predictive power of such calcifications.

PET SUV measurements vary between facilities
For lung cancer patients undergoing chemotherapy and radiation, PET can be a good way to monitor and even predict treatment response. But the response measured in standardized uptake values (SUVs) can vary significantly depending on the facility in which SUV is measured.

DECT permits more detailed urinary stone analysis
CHICAGO - Dual-energy CT (DECT) could potentially take urinary stone analysis beyond traditional distinctions of uric acid versus nonuric acid composition, identifying more stone types and enabling more patients to be treated noninvasively.

CT equivalent to IVUS for culprit plaque detection
CHICAGO - CT can distinguish the culprit coronary artery lesion in patients with suspected acute coronary syndromes as well as intravascular ultrasound (IVUS) can, according to a study presented on Wednesday at the RSNA meeting.

UCSF adds bone mineral density test to VC colon screening
CHICAGO - It's two tests in one! And both tests attend to critical health screening needs in older adults, according to University of California, San Francisco (UCSF) researchers. They found that adding a CT-based bone mineral density test to VC data is an easy way to increase the utility of a single CT dataset.

Dual-energy CT helps distinguish PE from other perfusion defects
CHICAGO - Detecting pulmonary perfusion defects at CT is considered good evidence for the presence of pulmonary embolism (PE), but not all perfusion defects represent PE. Dual-energy CT can distinguish non-PE causes of perfusion defects from the real thing, according to Korean researchers.

Cardiac stress MR tops SPECT, showing cause of chest pain
CHICAGO - Johns Hopkins researchers found that cardiac stress MRI not only outperforms SPECT for detecting acute myocardial infarction in patients presenting to the emergency room with chest pain, it reveals important information about the cause of the pain, even when symptoms are unrelated to coronary artery disease.

Nodule measurement streamlined with space-scale analysis
Researchers from Florence, Italy, have developed a robust and accurate method of measuring most lung nodules, improving the odds that growing lesions can be detected at CT with greater accuracy and reproducibility compared to current methods that rely on prior segmentation of the CT data.

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.
