Eric Barnes[email protected]PACS/VNAMouse roars in workstation navigational studyA 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.February 8, 2004CTMR, CT detect cystic pancreatic lesions, but malignancy a tough callCT 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.February 4, 2004CTTailor insufflation technique to the patient, says VC researcherInsufflation 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.January 29, 2004CTLung CAD makes strides in nodule detectionA 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.January 29, 2004CTCT coronary calcium attenuation affected by body mass, lesion locationResearchers 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.January 27, 2004CTAuntMinnie's Virtual Colonoscopy Radiology InsiderOver 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.January 25, 2004CTVirtual Colonoscopy Radiology InsiderTen years of virtual colonoscopy practice have shown that insufflation is key to success with the technique. Those who would master insufflation's intricacies might also do well to spend some time with Dr. Elizabeth McFarland and colleagues from Washington University in St. Louis.January 25, 2004CTExperience sharpens role of IV contrast-enhanced VCIntravenous contrast enhancement has often gotten a cool reception from virtual colonoscopy providers, who are understandably wary of adding to the cost or risk of the exam. But a growing body of literature demonstrates that IV contrast is the right choice in certain patients.January 18, 2004CTCapsule endoscopy fares well in small bowel versus CT, barium enemaIn the first multimodality assessment of a recently approved wireless capsule endoscopy (CE) system, the technique detected several types of pathologies better than CT and barium enema in patients with suspected small-bowel pathologies who had no evidence of stricture.January 13, 2004CTLower cardiovascular risk makes virtual colonoscopy safer, study findsRadiologists who perform virtual colonoscopy often cite its lack of perforation risk as a key advantage over endoscopy. VC is believed to offer other safety advantages as well, particularly in terms of cardiovascular risks. But no one had compared these effects empirically until researchers from London's St. Mark's Hospital decided to give it a go.December 30, 2003Previous PagePage 224 of 258Next PageTop StoriesPractice ManagementTurnover increasing among radiology practicesExcessive workload, being a female, and working in nonacademic practices are tied to higher turnover among imaging practices.CTFibrosis pattern on CT predicts CPFE progression rate, but not survivalUltrasoundCould less ultrasound lead to less thyroid cancer overdiagnosis?Nuclear MedicineGenetic mutations linked to poor outcomes in Pluvicto patientsSponsor ContentHow Agentic AI Is Transforming Radiology Ops
