Toshiba Medical Systems recently presented "Low-Dose Myocardial Perfusion Imaging" and an update on the CORE320 Multicenter Trial at the recent European Society of Cardiology Congress held in Stockholm
Myocardial Perfusion
It is now possible to perform a comprehensive cardiac functional and morphological analysis in just one, low-dose examination using Toshiba’s Aquilion ONE. This technology can reduce the need to perform multiple examinations using different modalities, a true economic advantage and valuable contribution in cardiac healthcare.
Until now, CT cardiac imaging has been hampered when quantifying cardiac tissue functionality caused by obstructed coronaries and/or infarcts. In order to visualise the entire heart, other scanners need to move the patient, causing undesired, time-delayed, contrast distribution over the heart. The unique 16cm z-axis coverage of the Aquilion ONE, allows scanning of the heart at a single moment in time, resulting in temporal homogeneous contrast distribution.
Myocardial Perfusion is interpreted by comparing rest and stress data. The rest scan is usually performed using a low-dose, prospective CT angiography protocol. Pending body mass index and heart-rate, sub-mSv protocols may be applied. After administration of a pharmacological stress agent, a low-dose stress scan is performed.

Myocardial Perfusion Scan
Myocardial perfusion scan is a cardiac diagnostic procedure using nuclear medicines so as to analyze cardiac functions and reveal any problems related to cardiac muscles. Myocardial perfusion scan helps to evaluate various cardiac diseases or dysfunctions ranging from coronary vessel block up to the hypertrophic diseases of heart like the cardiomyopathy or ventricular abnormalities.
