Based on quantification of iodine within tissues, DECT may be able to estimate blood volume as a surrogate of organ perfusion at contrast enhanced CT. Read more

Obviating the need for an additional image acquisition during rest holds promise to substantially reduce radiation doses involved with CT-based myocardial perfusion imaging. Read more

At sub-second, low radiation dose CTA of the chest, use of individualized, patient-based contrast media delivery protocols results in reliable, diagnostic contrast enhancement of all target vessels. Read more

Nov 27, 2011 to Dec 2, 2011. The Radiological Society of North America (RSNA) holds its 97th Annual Scientific Meeting in Chicago, Illinois (USA). Read more

For the detection of myocardial perfusion deficits seen on SPECT, DECT-based analysis of myocardial iodine distribution is superior to single-energy CT spectra. Read more

Using iodine concentration as a quantitative surrogate for perfusion could enhance the potential role of DECT as a stand-alone modality for integrative imaging of ischemic heart disease. Read more

Compared with SPECT, DECT showed more accurate detection rates for reversible and fixed perfusion defects seen on cMRI, and revealed higher agreement for identifying the type of perfusion defect. Read more
