Mouse roars in workstation navigational study

A lowly computer mouse aced the race for best input device in lung CT datasets. In a user study conducted at the University Hospital of Cleveland, the murine contender won out over an array of navigational devices, including a trackball, a video game joystick, a jog-dial, and a gamepad.

MR, CT detect cystic pancreatic lesions, but malignancy a tough call

CT and MR are both good at characterizing the morphology of cystic pancreatic masses, according to researchers at the University of California, San Francisco. The problem is with the masses themselves, which can appear benign when they aren't, and vice-versa.

ISET talks offer innovative ways to survey aortic aneurysm repair

By Edward Susman

MIAMI BEACH, FL - CT scans following endovascular repair of the aorta could be a thing of the past if tiny sensors currently in development prove successful, according to a presentation at the International Symposium on Endovascular Therapy (ISET) this week.

Tailor insufflation technique to the patient, says VC researcher

Insufflation has been shown to be crucial to the success of virtual colonoscopy. Adequate colonic distension is more important than thin-section imaging or even multidetector-row scanning, and ranks right up there with bowel prep in terms of the factors affecting lesion detection, according to Dr. Elizabeth McFarland.

Lung CAD makes strides in nodule detection

A survey of the latest nodule-detection studies finds that lung CAD algorithms have evolved to become unmistakably useful to radiologists. In nine studies presented at the 2003 RSNA meeting in Chicago, CAD schemes developed by multimodality vendors and independent firms alike all brought significant sensitivity gains to the tedious job of lung-nodule detection.

CT coronary calcium attenuation affected by body mass, lesion location

Researchers from the University of Iowa have concluded that CT attenuation varies significantly depending on the subject's body mass, a finding that casts doubt on the accuracy of phantom-based scanning measurements.

AuntMinnie's Virtual Colonoscopy Radiology Insider

Over the past year, lung CAD algorithms have evolved to become reliable second readers of thoracic CT exams. In study after study presented at the 2003 RSNA meeting, lung CAD systems could be counted on to improve the detection rate of solitary pulmonary nodules, even small or hard-to-find abnormalities such as those adjacent to vascular structures.
