VC CAD plus 3D improves sensitivity for novice readers April 21, 2009 -- Computer-aided detection (CAD) with 3D viewing improves sensitivity for polyp detection among less experienced readers, and may also speed up reading times and reduce false-positive detections. On the other hand, the performance of experienced readers did not improve significantly with CAD use, researchers from the University of Rome concluded.
IHE's XDS-I profile may help with CD import dilemma April 14, 2009 -- Institutions that struggle with managing patient CDs from outside locations should consider taking advantage of the Integrating the Healthcare Enterprise (IHE) Cross-enterprise Document Sharing for Imaging (XDS-I) integration profile, according to a presentation at the 2009 European Congress of Radiology.
Gated SPECT best indicator for cardiac events April 13, 2009 -- Myocardial perfusion abnormalities obtained after stress, as well as the extent of scar tissue detected by gated SPECT, are the best predictors of cardiac events in patients with suspected or known ischemic heart disease, according to a new Italian study.
U.K. specialists want relevancy, detail in radiology reports April 10, 2009 -- Radiology reports that are most beneficial include clinical comments and are presented in a consistent, easy-to-read tabular format, according to a survey of physicians ordering radiology procedures from a community hospital in northwest England.
Adding chest CT to VC not cost-effective, study finds April 7, 2009 -- Adding a chest CT scan to screening virtual colonoscopy isn't cost-effective in a cohort of average-risk patients, a new model-based analysis concluded. Although the additional anatomic coverage increased the clinical efficiency of CT-based screening, the combined test would not detect enough serious pathology to cover the costs of detection and follow-up of disease.
MDCT holds promise for advanced osteoporosis scan April 6, 2009 -- CT could become an important player in the emerging field of structural bone assessment, according to researchers from Berlin and San Francisco. They believe the modality is capable of evaluating trabecular structures from the extremities to the vertebrae, outperforming even high-resolution peripheral quantitative CT (HR-pQCT) in some conditions.
Virtual colonoscopy CAD finds most cancers April 3, 2009 -- A computer-aided detection (CAD) algorithm designed to find polypoid lesions of the colon also does fairly well at finding frank cancers, researchers from the U.K. concluded. But sensitivity varies depending on the system settings and the quality of the prep.
Single-entry APBI offers flexibility in treating breast cancer April 3, 2009 -- Until recently, accelerated partial-breast irradiation (APBI) was not an option for most women with small breasts or a tumor located close to the chest wall and lung or the surface of the skin. The introduction of multicatheter single-entry brachytherapy devices, however, is beginning to change the situation.
Digital tomo works well for some kidney, ureteral stones April 2, 2009 -- A new study by Belgian researchers indicates that digital tomosynthesis could be useful for assessing ureteral and kidney stones, particularly for screening patients prior to CT. But the digital radiography technique has different levels of accuracy depending on the location and size of stones.
CT for brain metastasis unnecessary after PET/CT April 2, 2009 -- A CT scan is often ordered to find brain metastases in lung cancer patients. But if a whole-body PET/CT scan is already available from the original workup, there's no need for a dedicated CT scan, according to researchers from Belgium, who found that the CT portion of the PET/CT scan is enough for the initial diagnosis.
