Automated polyp measurement supports risk assessment
August 26, 2008 -- Automated polyp-measurement software performed as well as human readers in a study that could lead to more efficient screening with virtual colonoscopy. The study sought to evaluate the accuracy of an automated polyp size measurement tool and its effectiveness for risk stratification in 305 subjects. Read More

ROI changes colorectal tumor perfusion measurements
August 26, 2008 -- The development of automated perfusion-mapping software for CT data has opened up intriguing possibilities for the assessment of tumor vascularity, specifically for monitoring response to antiangiogenic drug treatment. But where, precisely, to measure tumor vascularity is a question that had not been addressed, according to U.K. researchers. Read More

Quantitative stress echo can reliably find coronary artery disease
August 18, 2008 -- Quantitative stress echocardiography with contrast-based myocardial blood flow measurements can successfully detect coronary artery disease, according to research published online in Heart. Read More

PET with C-11 PiB can assess beta-amyloid brain deposits
August 12, 2008 -- PET using carbon-11-labeled Pittsburgh Compound B (C-11 PiB) shows promise for assessing beta-amyloid deposits in the brain and may have a potential role as a diagnostic aid for early Alzheimer's disease, according to research published online in the Archives of Neurology.

US-guided core-needle breast biopsy offers alternative to surgery
August 7, 2008 -- Researchers at the Medical University of Vienna and Memorial Sloan-Kettering Cancer Center studied 14-gauge ultrasound-guided biopsy's false-negative and underestimation rates, concluding that the technique provides an accurate alternative to surgical excision for evaluating nonpalpable breast lesions.

PACS data-mining tool analyzes CR retake rates
August 5, 2008 -- Researchers from Spain have developed software that analyzes PACS data to automatically perform quality control analysis of retake rates of computed radiography studies. They believe their QC tool could make it easier for imaging facilities to reduce retakes and improve the overall quality of service. Read More

Image tools cut false positives in unprepped VC
August 4, 2008 -- Aiming to optimize the results of prepless vitual colonoscopy, researchers have developed a pair of tools to process unprepped CT data and make it easier to read. According to the results of a pilot study, the methods reduced false positives by as much as one-third. Read More

Gestix device gives brain surgeons a hand in the OR
July 31, 2008 -- How could the amount of operating room time scheduled for complex brain surgery some day be dramatically reduced? With a wave of the hand -- more specifically, through a graphical user interface that responds to hand motions rather than keyboard or mouse commands. Read More

FOBT-screened cohort yields too many positives for VC
July 28, 2008 -- Virtual colonoscopy (VC) seems a promising way to sort through patients with a positive fecal occult blood test (FOBT), considering the latter's demonstrated low sensitivity and high false-positive rate. But in a screening cohort from the Netherlands, polyps and cancer were so common in FOBT patients that VC hardly seemed worth it. Read More

Time doesn't diminish risk of cancer relapse after lumpectomy and RT
July 21, 2008 -- The risk of developing cancer again in the same breast after breast-conservation surgery and radiation therapy does not diminish over time, a long-term study of more than 1,000 women with stage I and stage II breast cancer has revealed. Read More
