This article compares cost-effectiveness and potential lifetime benefits of using dual-energy computed tomography (DECT) for myocardial perfusion assessment instead of single photon emission computed tomography (SPECT) for the workup of coronary artery disease (CAD). 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

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

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

The following question has been sent by Dr. Shrinivas Desai: DSCT Myocardial perfusion versus SPECT CT myocardial perfusion: Jaslok Hospital in mumbai, India is buying Siemens DSCT (Flash Definition Dual source Dual energy). We already have a SPECT on which thallium myocardial perfusion is done. The nuclear medicine department is considering acquiring … Read more

In conclusion, our initial experience suggests that DECT, as a single examination, might be promising for the integrative analysis of the coronary artery morphology and the myocardial blood supply and is in good agreement with ICA and SPECT. Read more

The following question has been sent by Antonio Maestro: Use of Flash and DE to replace SPECT in detection of ischemia tests? Hi, i am doing a research to assess the clinical and patient workflow results of using a DSCT Definition Flash for the Chest Pain Unit patients. It seems clear to me … Read more
