MDCT for chest pain: Whom to scan, when to discharge
Coronary CT angiography is proving to be reliable for triaging chest pain patients in the emergency room. Its high negative predictive value for ruling out acute coronary syndrome suggests that patients with negative results and negative cardiac enzymes can be safely discharged. But most are still admitted for observation, at great expense to the U.S. healthcare system.

MDCT identifies malignant pancreatic cysts for surgery
Thin-section MDCT is more useful than previously thought for identifying patients with pancreatic intraductal papillary mucinous neoplasms (IPMN). A new study found that CT accurately identified IPMN features that were associated with both malignancy and parenchymal invasion.

MRI evaluation of chest pain cuts acute coronary syndrome
Emergency department physicians improved their ability to predict acute coronary syndrome (ACS) by adding a T2-weighted sequence to their cardiac MRI protocol, according to a new study from Harvard Medical School and Massachusetts General Hospital in Boston.

CAD steals show from U.S. research database
A painstakingly compiled database of CT lung scans was no match for a university's computer-aided detection (CAD) system. The CAD system found more lung nodules in more patients than the original expert reader panel, which had reviewed each scan twice.

CT databases aimed at lung imaging research
The lack of quality controlled imaging databases has complicated lung cancer research, but help is on the way. A multiyear, multicenter project funded by the National Cancer Institute is delivering new lung imaging databases on which computer-aided detection (CAD) systems can be tested.

Prospective gating minimizes dose in 320-slice CTA
In a new study, researchers from Brigham and Women's Hospital evaluated the impact of different amounts of "padding," or phase window width, on image quality and dose in 320-slice prospectively gated CT angiography (CTA).

Novel CAD concept reduces lung nodule false positives
A new computer-aided detection (CAD) algorithm detected more lung nodules with fewer false positives than conventional schemes, potentially delivering a better and more cost-effective way to screen for lung cancer with CT.

Image tools cut false positives in unprepped VC
Aiming to optimize the results of prepless vitual colonoscopy, researchers have developed a pair of tools to process unprepped CT data and make it easier to read. According to the results of a pilot study, the methods reduced false positives by as much as one-third.

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.
