Thang Long Lac Viet International Hospital opened the Philips Spectral CT 7500 super CT system

The Philips Spectral CT 7500 super CT system supports cardiovascular, neurological, and oncological diagnoses with in-depth image data, reducing X-ray and contrast agent doses..

Thang Long Lac Viet International Hospital has just opened and put into operation the Philips Spectral CT 7500 super CT system, on August 26. The system operation ceremony took place with the participation of representatives of the Ministry of Health, the Dutch embassy, ​​the Vietnam Radiology & Nuclear Medicine Association, the Vietnam Armed Forces Imaging and Nuclear Medicine Association, Philips Vietnam representatives and many leading medical experts.

The unit's representative shared that the investment in the system comes from the practical requirements of modern medicine, when clinicians not only need to determine the location of the lesion but also need accurate quantitative data on the nature of histology, microvascular perfusion and the level of response after treatment.

The Philips Spectral CT 7500 uses dual-layer receiver-based spectroscopy technology, allowing the simultaneous acquisition of conventional black-and-white anatomical structure and energy spectrum data in a single scan. This rich source of spectral data is completely stored from the beginning, allowing doctors to recreate quantitative maps such as Iodine or MonoE single-energy image sequences at any time to clarify clinical questions without the patient having to take a second scan.

The breakthrough point of the system is the application of artificial intelligence (AI) algorithms throughout the entire process. AI Precise Cardiac technology automatically compensates for noise caused by mechanical motion of the heart, helping to examine and reproduce sharp images of the coronary artery lumen and stent frame even in cases with tachycardia above 180 beats/minute or arrhythmia without requiring the use of antihypertensive drugs. In addition, AI also automatically calculates the optimal radiation dose according to each person's physical condition and quantitatively analyzes microstructure, supporting early detection of millimeter-sized abnormalities that are easily hidden on conventional radiographs.

The super-fast image acquisition speed is also a great advantage of the system as it only takes about one second to survey the cardiovascular, neurological and cranial nerves and less than 2 seconds to fully scan the chest, abdomen and pelvis. This speed helps make the most of the "golden time" in stroke and trauma emergency care, while also limiting breathing artifacts in the elderly or pediatric patients who have difficulty holding their breath for a long time. Along with speed, the machine is optimally safe by reducing up to 85% of X-ray dose and about 65% of contrast agent thanks to the ability to amplify Iodine signals. The virtual drug-free imaging (VNC) feature also helps to remove contrast directly from the scan data, replacing a separate drug-free imaging phase to protect maximum kidney function for the patient.

In clinical practice, the system promotes value in many key specialties. With stroke, the VNC feature helps accurately distinguish between real brain hemorrhage and contrast dye retention after thrombectomy, while eliminating skull base artifacts to early identify areas of fulminant cerebral infarction. In cardiology, the machine allows simultaneous assessment of coronary artery stenosis structure and myocardial perfusion area, eliminating calcification artifacts to see through the metal stent frame. For oncology, the Iodine map helps highlight the boundaries of poorly enhancing tumors and clearly delineate between active tumor tissue and scarred, necrotic tissue after chemotherapy and radiotherapy.

In parallel with the machine operation ceremony, Thang Long Lac Viet International Hospital coordinated with the Vietnam Association of Radiology & Nuclear Medicine and Philips Vietnam to organize a scientific conference "The role of 512-slice spectral CT in clinical practice - Breakthrough solution in comprehensive diagnosis of cardiovascular and oncology".

Professional reports at the conference clarified the role of spectral data in solving complex clinical problems, especially the ability to provide complete histological data, optimize radiation dose and contrast agent amount for the elderly, people with impaired kidney function and cancer patients requiring prolonged monitoring.

On the occasion of system operation, Thang Long Lac Viet International Hospital launched a 30% discount program on the cost of spectral CT scans in the first period, and at the same time applied full payment benefits under the health insurance regime as prescribed, creating the most favorable conditions for patients to access international standard diagnostic technology right in Hanoi.
