Mount Elizabeth Hospital first in Southeast Asia to acquire NAEOTOM Alpha from Siemens Healthineers

  • The NAEOTOM Alpha is the world’s first CT scanner with photon-counting technology.

  • Mount Elizabeth Hospital (MEH) will be the first hospital in Southeast Asia to offer patients the benefits of photon-counting technology. 

Mount Elizabeth Hospital will be the first hospital in Southeast Asia to acquire NAEOTOM Alpha, the world’s first photon-counting CT with the aim to optimise diagnostic and treatment pathways for patients in Singapore. NAEOTOM Alpha is a photon-counting Dual-Source Computed Tomography (DSCT) system that utilises cadmium telluride crystals in its CT detector which convert X-ray photons directly into electrical signals instead of first converting it into visible light as with conventional CT imaging. This overcomes the loss of information from standard energy integrating detectors used in conventional CT systems, and produces sharper, clearer and higher-detailed images without the need for higher radiation doses.

A CT scan allows doctors to view images of body tissues, including lungs, bones, soft tissue, and blood vessels at the same time, in order to make an appropriate diagnosis. The new photon-counting DSCT system produces high-resolution images through spectral imaging technology. This is particularly useful for patients who are breathless, and for paediatric patients without the need for sedation.

“Our acquisition of Siemens Healthineers' new photon-counting DSCT system underscores Mount Elizabeth Hospital and Parkway Radiology’s commitment to provide our doctors with the latest, most effective tools to make quick, accurate diagnoses,” says Ms Tan Yujuan, Chief Executive Officer of Parkway Radiology. “This not only translates to better treatment outcomes supported by more informed and reliable clinical decisions by our doctors, but also offers our patients greater assurance, accessibility and comfort.”

The new photon-counting DSCT system counts toward one of the several major equipment and technology upgrades planned under MEH’s “Project Renaissance”, the hospital’s first major infrastructure refurbishment since its establishment in 1979. The S$350 million endeavour will transform the medical institution into a modern and integrated multiservice hub that provides patients with seamless care upon its completion in 2025.

According to Dr Peter Goh, Group Medical Director for Parkway Radiology, “Parkway Radiology has always held on to the ideal of breaking new ground and staying at the forefront of the technology of medical imaging. The addition of the photon-counting DSCT to our armamentarium of radiological equipment maintains our philosophy of always advancing for the benefits of our patients. The demand for and expectations of clinical imaging are increasing at an exponential rate, with several key trends such as the need for more quantifiable metrics and functional data. The superior material decomposition capability of the photon-counting CT over existing CT technology potentially allows for multi-tracer imaging and the opportunity to expand tissue characterisation of CT beyond what is currently known.”

“With the introduction of photon-counting DSCT in Mount Elizabeth Hospital, we aim to provide physicians and radiologists with the latest technology to support diagnosis and treatment in multiple clinical disciplines such as cardiology, pulmonology, and oncology,” states Ms Siow Ai Li, Managing Director at Siemens Healthineers Singapore. “We are proud that Mount Elizabeth Hospital is the first to acquire the photon-counting DSCT in Southeast Asia as this technology will improve clinical decision-making for patients in Singapore.”
