Parallel processing gives boost to mammographyStrong evidence suggests that MR imaging is the most sensitive of all breast imaging techniques, including state-of-the-art mammography and high-frequency breast ultrasound. In contrast to mammography, the sensitivity and specificity of MR are not impaired by dense breast tissue, fibrocystic disease, or therapeutic interventions such as postsurgical scars or radiotherapy-induced fibrosis.

MSCT venography finds cerebral thrombosesDural sinus and cerebral venous thromboses (CVT) are difficult to diagnose. Symptoms are often nonspecific and may evolve slowly, and anatomic variations can further complicate diagnostic decision making. Unilateral aplasias of the transverse or sigmoid sinus, frontal agenesis of the superior sagittal sinus, and high partitions of the transverse sinus are common pitfalls in the diagnosis of CVT.

CTA revolutionizes treatment of peripheral vascular diseaseWe continue to be both amazed and intrigued by the hype showered on cardiac CT angiography and the corresponding lack of hype given to peripheral vascular CTA. No doubt, 64-slice cardiac or coronary CTA is potentially a revolutionizing technology, but PV-CTA has already revolutionized the comprehensive diagnosis and treatment of peripheral vascular disease.

Canada develops ambitious electronic health networkCanadian officials estimate that by 2010, at least half of all residents will have their own electronic health record. The EHR is intended to include a cradle-to-grave clinical history, using a single patient identification number. It will eventually be interoperable across the country and its multitiered healthcare delivery organizations. This prediction is not just a political pipedream, as implementation is already well under way.

IHE portable data profile fixes interoperability snagsThe shift from film-based images and hard-copy reports to soft-copy reading and digital archiving has sparked challenges when it comes to sharing and distributing data. Referring physicians and patients now typically expect to receive medical data and images on portable media such as compact discs and DVDs. But not all of these portable devices are reliably interoperable with PACS and enterprise IT systems.
