Use of the AI-powered Salix Coronary Plaque module, which offers detection of high-risk plaque within 10 minutes based off of CCTA scans, will reportedly qualify for $950 in Category 1 CPT reimbursement in 2026.
Positive results strengthen case for CT colonography screening
December 1st 2006This fall brought good news for advocates of CT colonography. A study in the November issue of Radiology presented the latest results from the University of Wisconsin, and they were very good: in a population of 1110 patients, CT colonography demonstrated a positive predictive value of 93.8% for polyps 6 mm and larger, up from 58.5% in an earlier trial conducted at the same institution (Radiology 2006;241:417-425).
Numa debuts storage, connectivity tools
December 1st 2006Nuclear medicine specialist Numa showed at the 2006 RSNA meeting enhancements for NumaLink, a cross-vendor data translation product, and NumaStore, a gamma camera and PET/CT image management system. The products promise greater connectivity within the nuclear medicine department and between nuclear medicine and radiology. Among NumaLink’s enhancements are DICOM translation capabilities for proprietary PET data sets, including those generated using Siemens and GE PET systems. The NumaStore upgrade supports Siemens’ preclinical microPET and the Inveon Dedicated PET small-animal imaging systems.
GE enhances LightSpeed VCT at RSNA meeting
November 29th 2006Software upgrades introduced by GE Healthcare this week for the company's LightSpeed VCT scanner promise to cut patient x-ray dose for coronary CT angiography by 70% or more and double the area covered during dynamic angiography and perfusion.
Software boosts accuracy, reduces reading time for bone scans
November 29th 2006Software designed by researchers at the University of Chicago helps detect interval changes in successive nuclear medicine bone scans, and can reduce interpretation time by up to 32%, according to research presented in an educational exhibit at the RSNA meeting.
Alternative bowel preps prove useful for CT colonography
November 27th 2006Noncathartic bowel preparation is not an obstacle to accurate CT colonography (CTC). Preparations such as fecal tagging, electronic cleansing, and the use of stool-subtraction algorithms produce results comparable to those obtained with conventional bowel-cleansing preparations, according to studies presented at the 2006 RSNA meeting.
MR colonography proves effective, but no more palatable to patients
November 27th 2006Although MR colonography (MRC) is proving to be an effective method of colorectal screening, patients are no more likely to accept it than optical colonoscopy, according to two studies presented at the RSNA meeting.
Alternative bowel preps prove useful for CT colonography
November 27th 2006Noncathartic bowel preparation is not an obstacle to accurate CT colonography (CTC). Preparations such as fecal tagging, electronic cleansing, and the use of stool-subtraction algorithms produce results comparable to those obtained with conventional bowel-cleansing preparations, according to studies presented at the RSNA meeting on Monday.
ScImage readies next-generation PACS
November 26th 2006IT specialist ScImage debuted a multidepartment PACS, Version 3.0 PicomEnterprise, at the 2006 RSNA meeting. The PACS uses a single database, which allows exams to be scheduled, tracked, reported, archived, and distributed across radiology, cardiology, nuclear medicine, and orthopedics using one Web-based log-on.
PET/CT colonography outperforms CT colonography for tumor staging
November 26th 2006The assumption that CT colonography is the logical choice for pairing with optical colonoscopy to stage colorectal cancer took a hit at the RSNA meeting today. A prospective study from Europe shows that whole-body FDG-PET/CT is significantly more accurate than CT colonography for staging colorectal tumors.
GE allies with healthcare providers to develop CT colonography
November 22nd 2006GE Healthcare will sign today an agreement with the Cleveland Clinic and outpatient provider AmSurg to explore how CT colonography might evolve into an accepted screening tool for colon cancer. The agreement calls for GE to provide equipment, engineering, and support; eRadiology, the teleradiology group within the Cleveland Clinic radiology division, will provide clinical expertise; and AmSurg will provide the outpatient facilities for conducting CTC exams.
Nuclear medicine techs love job but see changes coming
November 21st 2006Nuclear medicine technologists enjoy their jobs and find their salaries near the top of the scale for professions with similar educational requirements. They are concerned, however, about changes being wrought by new imaging technology and practice patterns, according to a survey sponsored by the Society of Nuclear Medicine Technologists Section.
Holiday travel can ring more than jingle bells
November 15th 2006The Society of Nuclear Medicine wants healthcare providers to inform patients undergoing nuclear medicine treatment or testing that they may set off security alarms at high-risk locations with the radioactive materials in their bodies.
FDA reviewers stay red hot in September
November 9th 2006The imaging industry tallied another 34 FDA clearances in September, pushing the running count for the year to 261. Image management led all categories with 14 devices, followed by x-ray with 10, radiotherapy with four, ultrasound and CT each with two, and nuclear medicine with one. A surgical microscope accessory that is used to view intraoperative cerebral blood flow fits none of the traditional categories.
3D display creates stereoscopic images without glasses
November 1st 2006Siemens Medical Solutions will spotlight a new kind of medical display at the upcoming RSNA meeting, one that creates volumetric images that appear to hang in space beyond the flat screen of the monitor. Unlike similar systems that have popped up in the past, however, this display will not require the user to wear glasses.
