CARS report: Fuzzy theory yields sharper CTA images
BARCELONA - Coronary CT angiography isn't as easy to perform as it could be, according to Chunliang Wang, who discussed the problem of hidden coronary arteries and introduced a novel segmentation method that might make them easier to examine at the 2008 Computer Assisted Radiology and Surgery (CARS) meeting.

CARS report: CAD prompts range of behaviors in readers
BARCELONA - How computer-aided detection (CAD) software works in theory is one thing, and how it functions in practice is another, as radiologists who use CAD have come to appreciate. But the ways in which readers react to CAD prompts, a subject that has received scant attention, has important implications for both CAD design and reader training.

CARS report: Imaging workstations key to patient-specific care
BARCELONA - At the 2008 Computer Assisted Radiology and Surgery (CARS) conference on Wednesday, Dr. Heinz Lemke and Dr. Michael Vannier discussed a new patient-specific disease model, the role of advanced imaging and therapeutic workstations in it, and the army of researchers working to make it so.

Radiographers perform VC with CAD -- and controversy
A new study from London put radiographers in charge of reading virtual colonoscopy (VC) data, with their performance monitored with computer-aided detection as a second reader. The study raises the question of whether it's inappropriate -- or even dangerous -- to allow nonradiologists to screen with VC.

Diligence can reduce missed lung cancers in CT
A new lung cancer model based on 1,520 CT screening subjects found that five years of annual lung cancer screening increased lung cancer detection by an estimated 37% and decreased lung cancer-related deaths by 28%, according to a study in the journal Radiology.

Thin slices more important than adequate tube current in VC CAD
Computer-aided detection (CAD) performance is undaunted by low tube current and its accompanying image noise. But CAD sensitivity is harmed by thicker CT slices, which generally increase the number of missed colorectal polyps in virtual colonoscopy, a new study reveals.

Video game technology speeds beating-heart surgery
Intracardiac reconstructive surgery can be used to repair defects in the beating heart while avoiding the need for cardiopulmonary bypass, but progress has been limited by a lack of reliable imaging tools. A new study introduces a solution based on video gaming technology to improve the results of real-time 3D echocardiography.

Family history of colon cancer may improve survival
Among patients with advanced colon cancer undergoing treatment, a family history of the disease is associated with significant reductions in both cancer recurrence and death, according to a study in the Journal of the American Medical Association. The risk is further reduced if the patient has more than one first-degree relative affected by the disease.

CT rules out malignancy in most pancreatic cysts
Today's volumetric MDCT images are yielding a troubling trove of small cystic lesions of the pancreas. The vast majority of such lesions smaller than 3 cm are benign, but it takes a bit of sleuthing to rule out malignancy based on imaging alone.
