Report from ARRS: Breast MRI CAD zeroes in on malignancies

April 17, 2008 Report from ARRS: Breast MRI CAD zeroes in on malignancies H. A. Abella -------------------------------------------------------------------------------- Computer-aided detection schemes for breast MR imaging have shown plenty of promise, but they always fall short of full automation and lesion characterization. Two recent studies, however, suggest CAD for breast MRI may be closing in on true cancer detection. Investigators presented results of a study featuring the ONCAD… Continue

Report from ARRS: Study establishes infection as NSF risk factor

April 14, 2008 Report from ARRS: Study establishes infection as NSF risk factor H. A. Abella -------------------------------------------------------------------------------- New evidence has surfaced pinpointing specific potential causes of nephrogenic systemic fibrosis. Findings sustain its relationship to some gadolinium-based contrast media, but they also suggest that infection, certain patient demographics, and even some drugs could be strongly associated with the condition. The studies… Continue

Structured query language extension supports content-based image retrieval

April 11, 2008 Structured query language extension supports content-based image retrieval Douglas Page -------------------------------------------------------------------------------- Schemes proposed to support growing interest in content-based image retrieval have generally failed to incorporate the use of structured query language to support similarity queries. Recent research from Brazil provides this ability. Similarity queries scan databases for objects similar to the reference object. To… Continue

PET tops CT for early characterization of malignant lung nodules

April 11, 2008 PET tops CT for early characterization of malignant lung nodules H. A. Abella -------------------------------------------------------------------------------- A large multicenter trial rates FDG-PET as more reliable than CT for the detection of malignant solitary pulmonary nodules. The findings suggest, however, that a combined rather than single-modality approach may lead to earlier treatment and help avoid invasive procedures. The clinical literature notes that suspicious lung… Continue
