Supracardiac Total Anomalous Pulmonary Venous Return (TAPVR)

Supracardiac total anomalous pulmonary venous return (TAPVR) case study: A term newborn infant developed profound respiratory distress shortly after birth. After a negative echocardiogram, venovenous ECMO was performed. A cardiac CTA was requested, but complicated by the fact that the patient was on ECMO.

FDG-PET imaging tackles large arteries with atherosclerosis

A noninvasive technique to detect vulnerable atherosclerotic plaque is critically needed. Formation of atherosclerotic plaque is a dynamic inflammatory process that involves interactions between atherogenic lipoproteins and macrophages. As vulnerable plaques are usually numerous, extending beyond the culprit plaque and involving multiple vessels, targeting a single plaque underestimates the complexity and extent of disease. Thus, an ideal imaging modality should be able to identify the vulnerable arterial bed and, therefore, the vulnerable patient, to prevent the serious complications of atherosclerosis.

Ultrasound seeks out metastatic melanoma

Cutaneous malignant melanoma is a relatively common malignancy, and its incidence is increasing worldwide, especially in the Caucasian population. The clinical course of melanoma depends on tumor thickness, localization, ulceration, growth rate, and histology of the primary tumor. Metastatic spread may arise from very small masses.

Diagnostic ultrasound withstands test of time

Ultrasound has long been a prime target in imaging turf wars because it does not employ ionizing radiation. Radiology lost cardiac ultrasound, and it is questionable that the specialty will continue to be a major player in obstetrics.

Vioguard blasts germs off keyboards

Hospital-associated infections are a growing concern for hospitals. Some 1.7 million people pick up infections each year while in hospitals. More than 99,000 die. While these infections may come from several sources, studies have shown that computer keyboards are a leading contributor. With the introduction of their first product, a self-sanitizing keyboard, Seattle-based Vioguard hopes to eliminate the keyboard as a vector of infection in hospitals.

Cross-enterprise standard fosters imaging exchange

The Integrating the Healthcare Enterprise initiative is intended to enable plug-and-play interoperability between clinical information systems from different vendors. Embraced by most major healthcare IT vendors, the IHE harnesses existing healthcare and IT standards such as DICOM and HL7 into integration profiles. The profiles amount to technical recipes for how standards must be implemented by vendors to ensure interoperability for specific tasks and problems faced by healthcare providers.
