SOMATOM Definition Flash Essay
Unique to the SOMATOM Definition Flash are its Dual Source technology and the revolutionary Stellar Detectors. They make it possible to scan virtually any patient, both at very low radiation and contrast dose – no matter whether the patient has an unstable heart condition, cannot hold his breath, or is obese, very tall, poly-traumatized, or a moving child. Its unmatched innovations include a 78 cm gantry bore, 307 kg capacity, 2 x 100 kW, 2 m scan range, whole-organ perfusion coverage, and 75 ms temporal resolution.
Pediatric chest & body CT. Without sedation.
The SOMATOM Definition Flash scan speed resulted in a scan time of a fraction of a second for the whole chest and body, and we could show that there is no …show more content…
Thus, CT can be performed routinely in Dual Energy mode without additional dose or compromises in image quality. In case of Pulmonary Embolism (PE), the Dual Source DE examination shows improved capability to detect peripheral PE. Thus, the SOMATOM Definition Flash clarifies which dot on the image actually is a true clot that should be treated with anticoagulation.
Routine sub-mSv heart. Even in patients up to 90 kg.
For ruling out coronary stenosis in asymptomatic individuals, who are at low to intermediate risk of coronary heart disease, doctors are looking for dose sensitive examinations. With excellent image quality at a consistent dose below 1.0 mSv, the SOMATOM Definition Flash routinely delivers low-dose cardiac scanning. Even in patients up to 90 kg. It is even possible to achieve ultra-low radiation exposure of < 0.1 mSv in patients with a body weight ≤ 75 kg. Thus, sub-mSv cardiac CT paves the way for early detection of coronary artery disease in appropriately selected patients.

Blood flow and volume.
The SOMATOM Definition Flash provides dynamic myocardial stress perfusion imaging, while the hemodynamic relevance of stenosis can be evaluated by syngoVolume Perfusion CT (VPCT).
The ability to obtain accurate cardiac perfusion information, in addition to morphologic information from CT coronary angiography imaging, has significant implications. In a situation of intermediate coronary stenosis, the quantitative blood flow measurements allow immediate treatment decisions without the need for fractional flow reserve (FFR) with coronary catheterization. Already at the CT stage, doctors can therefore decide on the next steps: pharmacologic management or cardiac catheterization.
Cardiac Dual Energy. At 75 ms temporal resolution.
With SOMATOM Definition Flash Dual Source Dual Energy imaging has a high sensitivity and a good specificity for the qualitative assessment of myocardial perfusion.”* Siemens’ syngoDE Heart Perfused Blood Volume (PBV) color-codes myocardial perfusion, so that both coronary artery morphology and myocardial perfusion can be assessed in a single CT scan. The SOMATOM Definition Flash offers the industry’s highest temporal resolution (75 ms). Thus, it presents cardiac pathology with valuable innovations for the test of myocardial viability with Dual Energy and for ruling out coronary artery, pericardial, congenital heart, or valve
