German researchers have for the first time demonstrated in a randomizedfashion that dual-source CT delivers a high rate of evaluable coronaryartery images, even if no systematic approach to heart rate lowering isused. The finding could be beneficial for patients who cannot receivespecific premedication to lower heart rate, in patients in whom suchpremedication is logistically challenging, or in patients whose heartrate is not lowered sufficiently despite the use of premedication.

While cost-savings might not be immediately apparent, benefits of digital echo include increased accuracy and efficiency, ease of accessing information and better patient care.

Since its emergence within molecular imaging, SPECT/CT has steadily gained momentum. Early, as well as late adopters now look to the dual modality to create new opportunities for revenue expansion and methods of improving patient care. Still, it can be a hard sell to a group practice or department to purchase a hybrid system because the economic justification for it within nuclear cardiology remains unclear.

Incorporating coronary CT angiography into a cardiology practice’s imaging mix requires a thorough understanding of many things including potential turf issues, siting requirements, workflow and reimbursement. Despite these challenges, cardiovascular programs can maintain a competitive edge by incorporating coronary CTA, especially given the current environment of stiff competition, personnel shortages, overworked staff and decreased reimbursement.

The new 320-detector row CT scanner from Toshiba Medical Systems hasbeen shown to deliver consistently excellent image quality andiodinated contrast opacification, as well as a low radiation dose toimage the coronary arteries, according to researchers from Brigham andWomen’s Hospital.

The first clinical experience with high-speed myocardial perfusionSPECT imaging indicates that the technology delivers high image qualityand up to eight times increased system sensitivity compared withconventional SPECT.
