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.

Heart and brain PET scans from a study participant who developed Parkinson’s disease support a “body first” progression. The top pair of PET scan images show low F-18 dopamine-derived radioactivity in the heart (right, with N-13 ammonia PET scan on left). Later, brain scans showed a loss of dopamine-producing neurons and the individual developed symptoms of the disease. Image courtesy of the National Institutes of Health.

Preoperative axial extracellular contrast agent-enhanced (A-E) MRI and (F-H) follow-up CT images in a 71-year-old male patient with chronic hepatitis B and a serum neutrophil count of 4.2 × 109/L. A 5.6-cm mass with a 1.9-cm satellite nodule was detected in segments V and VIII. (A) The mass (asterisks, A-E) shows mild-to-moderate hyperintensity on T2-weighted images, (B) hypointensity on T1-weighted noncontrast-enhanced images, (C) less than 50% hyperenhancement on late arterial phase images, (D) nonperipheral washout and incomplete enhancing capsule on portal venous phase images, and (E) marked diffusion restriction on diffusion-weighted images (b = 800 sec/mm2). The mass was confirmed at histopathologic analysis as moderately differentiated hepatocellular carcinoma with microvascular invasion. With an advanced-stage recurrence after resection score of 19.8 points (4.2 + 5.6 + 10), this patient was assigned to the high-risk group (≥15 points) for advanced-stage recurrence. At follow-up, (F) noncontrast-enhanced, (G) arterial phase, and (H) portal venous phase CT images acquired at day 70 after surgery show multifocal intrahepatic recurrence and tumor thrombus in the left portal vein (black arrow, H).
