FDA Clears Siemens Somatom Edge Plus CT System

Premium CT system leverages artificial intelligence to automatically safeguard precise, consistent patient positioning

FDA Clears Siemens Somatom Edge Plus CT System

April 4, 2018 — The U.S. Food and Drug Administration (FDA) has cleared the Somatom Edge Plus computed tomography (CT) system from Siemens Healthineers with the FAST (Fully Assisting Scanner Technologies) Integrated Workflow with the FAST 3D Camera. The camera is the first patient positioning system powered by artificial intelligence (AI). Additionally, the new scanner allows for automated scan preparation, improved diagnostic confidence and customized patient dose, making it ideal for high-volume practices and emergency imaging environments.  

Incorrect patient positioning in CT may lead to additional image noise or increased levels of patient radiation dose. The FAST Integrated Workflow and FAST 3D Camera of the Somatom Edge Plus enables accurate, reproducible patient positioning. Fixed above the patient table, the FAST 3D Camera uses infrared technology and AI to recognize anatomical landmarks. The table then aligns to the correct position to scan the body region at isocenter based on the selected protocol. This means institutions can streamline image quality, reduce dose and potentially reduce repeat scans.

Equipped with TwinBeam Dual Energy, the 128-slice Somatom Edge Plus enables quantitative imaging and improved tissue characterization for diagnostic confidence. This additional information allows for precise visualization of iodine uptake in a tumor. The system’s split filter technology permits acquisition of two spectral energies for dose-neutral Dual Energy scans in clinical routine. Using this technology, providers may be able to reduce additional non-contrast scans by producing virtual non-contrast images based on the Dual Energy data.

The Somatom Edge Plus enables scanning of obese patients with strong diagnostic confidence due to its Straton MX Sigma X-ray tube, high power reserves at every kV value in 10-kV increments and the Stellar Infinity detector – resulting in sharp, high-contrast images at high speed and low dose. Tin Filter technology, which can be used in all routine examinations, enables CT scans at very low doses by shielding patients from clinically irrelevant radiation. In the case of CT lung scanning, for example, this technology enables scanning at levels associated with a standard X-ray examination.

Rafael Rivero, M.D., Global Head of Medical Affairs at MSI, said: "The importance of MyoStrain cannot be understated because of the test's immense clinical value and ability to quantify intramyocardial dysfunction across 48 segments of the heart. In a six-heartbeat MRI scan, MyoStrain arms physicians with novel clinical information about a patient's heart health."

Schematic depiction of the automated process for assessing fat, muscle, liver, aortic calcification, and bone from original abdominal CT scan data

Figure 1: Depiction of the fully automated CT biomarkers tools used in this study. (A) Schematic depiction of the automated process for assessing fat, muscle, liver, aortic calcification, and bone from original abdominal CT scan data. (B) Case example in an asymptomatic 52-year-old man undergoing CT for colorectal cancer screening. At the time of CT screening, he had a body-mass index of 27·3 and Framingham risk score of 5% (low risk). However, several CT-based metabolic markers were indicative of underlying disease. Multivariate Cox model prediction based on these three CT-based results put the risk of cardiovascular event at 19% within 2 years, at 40% within 5 years, and at 67% within 10 years, and the risk of death at 4% within 2 years, 11% within 5 years, and 27% within 10 years. At longitudinal clinical follow-up, the patient suffered an acute myocardial infarction 3 years after this initial CT and died 12 years after CT at the age of 64 years. (C) Contrast-enhanced CT performed 7 months before death for minor trauma was interpreted as negative but does show significant progression of vascular calcification, visceral fat, and hepatic steatosis.
