Automated CO2 insufflation edges patient-controlled air in VC

In a new multicenter study, researchers compared patient-controlled room-air insufflation to automated CO2 insufflation to determine if one offered better distension and/or less discomfort than the other.

3D CT measures accurately for total knee arthroplasty

Accurate implant alignment and ligament balance are essential for a successful total knee arthroplasty. These days CT is taking on a bigger role in presurgical planning, with increasing use of 3D measurements. And according to Korean researchers, the measurements based on 3D reconstructions are accurate and reproducible.

High osmolarity agent beats gadolinium in cardiac MR

A compact but concentrated dose of high-osmolarity contrast agent produced a better MR contrast profile than gadolinium in patients with chronic thromboembolic pulmonary hypertension, a U.K. team has reported.

X-ray alien head vanishes from duck stomach

News of an apparent extraterrestrial being that was lodged in a duck's gizzard is grabbing headlines from San Francisco to cyberspace. Workers at the International Bird Rescue Research Center in Cordelia, CA, were stunned when they examined a plain radiograph of a sick mallard, according to workers at the center.

Studies suggest 10-year colonoscopy intervals to age 80

Two population-based studies in the latest Journal of the American Medical Association address critical topics in colorectal cancer screening with optical colonoscopy. The results suggest that once-a-decade screening is sufficient for average-risk patients, but that the potential of screening to extend lives diminishes by age 80.

Concentrated iodine permits lower volumes in cardiac CTA

Cardiac CT can be performed successfully with lower contrast volumes and flow rates when contrast agents are more concentrated, according to a new study. Researchers in Germany reported that 16-slice cardiac CT angiography (CTA) produced equivalent opacification compared to the use of a less-concentrated agent and higher volumes.

Part I: Radiologists prepare for growing CT role in virtual autopsy

Imaging has a big future in virtual autopsy, and CT in particular seems headed for a major role. Noninvasive virtual exams can often do what traditional autopsy cannot, notably in identifying the dead and pinpointing the causes of death. For all but a few applications, investigators are finding CT to be the fastest and most accurate modality available to carry out this work.

Part II: Automated CT lung nodule assessment advances

Part II of our series on automated CT nodule assessment explores the how and why of lung nodule assessment in a few computer-aided detection (CAD) systems. The results of some recent studies suggest that current CAD algorithms may need more emphasis on the small, irregularly shaped nodules that constitute many primary lung cancers.

Ga-68 ABY-025 PET/CT and F-18 FDG-PET/CT images at baseline with F-18 FDG PET/CT follow-up after two cycles of treatment in biopsy-confirmed HER2-positive disease. (A) Patient with high Ga-68 ABY-025 uptake (SUVmax, 21), who previously received three lines of treatment. F-18 FDG-PET/CT follow-up showed complete metabolic response. (B) Patient with low uptake (SUVmax, 5.4), who previously received three lines of treatment. F-18 FDG PET/CT follow-up showed disease progression (a 68% increase in tumor glycolysis) despite HER2-targeted treatment. (C) Patient with heterogeneous Ga-68 ABY-025 uptake, who previously received seven lines of treatment. F-18 FDG-PET/CT follow-up showed heterogeneous response, with lesions higher in Ga-68 ABY-025 uptake tending to have better response. Arrows indicate biopsy sites.

Standard-of-care imaging (top row) demonstrates a perfusion defect on SPECT images (top left) and corresponding FDG radiotracer uptake on PET/CT image (top right) at the interventricular septum (green arrows). On combined F-18 FDG-PET/MRI (bottom row), there is nodular late gadolinium enhancement (LGE) at the interventricular septum (orange arrows) with corresponding FDG uptake (blue arrows).
