Eric Barnes[email protected]CTVC accreditation goals just a beginningVirtual colonoscopy accreditation by the American College of Radiology is in the works. Accreditation establishes practice standards and ensures that radiologists meet minimum compliance levels, but is it enough? For better performance and consistent results, best practices need to be defined at every level of care.February 15, 2005CTMDCT maybe equivalent to MRI, tops echo and SPECT for heart functionAnalyzing left ventricular function is the prelude to treating several cardiac diseases, and it seems that multidetector CT may now be equivalent to MRI for the task over a wide range of heart rates, according to researchers from Kyoto University Graduate School of Medicine in Japan. But another study gives MRI a slight edge still.February 14, 2005CTTraining key to VC performance, but how much is anyone's guessPoor results from some recent trials have cast doubts on virtual colonoscopy's diagnostic capabilities, and placed training issues center stage. Leading practitioners are unanimous in their view that special training is required to do VC well, yet no reliable criteria exist to define adequate training.February 7, 2005CTDo whole-body CT's costs outweigh the benefits?Weighing in on the issue of whole-body CT, a new study finds that the scans may be an expensive way to extend lives. Researchers from Boston estimated a cost of $151,000 for each additional year of life gained from the scans, while critics bashed the methodology.February 1, 2005CTCT venography plus CTPA finds more pulmonary embolismPulmonary embolism isn't ruled out nearly as often when indirect CT venography is added to standard CT pulmonary angiography, according to radiologists from New York City. Their study found that the combined imaging approach increased the detection of thromboembolic disease detection by 20% compared with CT pulmonary angiography alone.January 31, 2005CTIodine tagging regimen yields best VC resultsTagging agents and protocols are becoming important issues in virtual colonoscopy today, as researchers seek to eliminate the discomfort of cathartic bowel cleansing, and perhaps improve compliance rates for colorectal cancer screening. Researchers from Massachusetts General Hospital evaluated 11 different prep combinations, and found some surprising results.January 26, 2005CTUltrasound finds contrast extravasation in ER patients, CT confirms itIn a study with important implications for patients in emergency rooms, Italian researchers have shown that contrast extravasation can be readily seen on contrast-enhanced ultrasound. CT confirmed the findings in most of the patients.January 24, 2005CTDebate over 2D versus 3D VC reveals subtle differencesVirtual colonoscopy studies presented at the 2004 RSNA meeting showed some intriguing differences between 2D and 3D primary interpretation of CT datasets. Primary 2D interpretation was generally faster, for example, but 3D seemed to pick up a few more abnormalities, both true- and false-positive.January 20, 2005CTCT tracks renal cancer recurrence after surgeryCancer recurs in more than a fifth of patients who undergo resection for renal cell carcinoma (RCC), according to radiologists from South Korea. The most common recurrence site is the lungs, according to the researchers, who developed CT guidelines for detecting recurrent RCC based on a multiyear follow-up study of their own patients.January 19, 2005CTAuntMinnie.com Virtual Colonoscopy Radiology InsiderJanuary 16, 2005Previous PagePage 212 of 258Next PageTop StoriesNuclear MedicineGenetic mutations linked to poor outcomes in Pluvicto patientsTP53, PTEN, and RB1 mutations may serve as prognostic biomarkers.Womens ImagingAI support leads to more cancers found on DBTCTPROMISE: Women face higher heart disease risk at lower plaque burdensMolecular ImagingPET predicts faster cognitive decline in women than menSponsor ContentHow Agentic AI Is Transforming Radiology Ops
