Hong Ngoc General Hospital Pioneers Vietnam's First 2560-Slice CT Technology with World's Fastest Scan Speed and up to 96% radiation dose reduction, enabling single heartbeat coronary artery imaging, paving the way for ultra-fast, highly accurate cardiac diagnosis, especially optimized for patients with arrhythmias.
Arrhythmia: A challenge in CT imaging technology
Ensuring high-quality, clear imaging for accurate diagnosis has long been a challenge in patients with arrhythmias, such as tachycardia, irregular heartbeats, or atrial fibrillation.
The biggest challenge for patients with arrhythmias is the heart’s irregular movement, which often causes palpitations, discomfort, and makes it extremely difficult for them to remain still during a CT scan. This results in image artifacts that cause CT scans to appear blurred or distorted, making it difficult to analyze key metrics related to heart structure and size — ultimately reducing the accuracy of the diagnosis.
To address this issue, patients often need to undergo longer scan times and increased exposure to radiation and contrast agents in order to improve image quality. This can lead to various risks, including allergic reactions and kidney damage.
With previous generations of CT scanners, doctors often had to use heart rate-lowering medications (beta-blockers) to slow the heart rate to below 70 beats per minute during the CT scan. However, using these medications often made patients uncomfortable, led to long waiting times, or caused side effects that prevented the CT scan from achieving the desired results.
The groundbreaking advancement of the new-generation 2560-slice CT Revolution Apex Elite, equipped with a host of superior features, is considered a breakthrough solution that effectively overcomes these long-standing challenges.

2560-Slice CT technology – A comprehensive solution to imaging challenges in patients with arrhythmia
The 2560-slice CT scanner is considered the most advanced CT imaging system available in the world today, featuring the world’s fastest gantry rotation speed of just 0.23 seconds, this CT scanner can capture images of the entire coronary artery system in the blink of a single heartbeat, unaffected by a fast, slow, or irregular heart rate.
Especially noteworthy is that the system does not require ECG gating - an unprecedented advancement compared to previous generations of CT scanners. As a result, it allows even the smallest lesions to be captured in under one second while still delivering ultra-high-resolution, highly detailed images. This also plays a crucial role in significantly shortening scan time and minimizing radiation exposure, thereby reducing potential risks for patients.
The exceptional advantages of the 2560-slice CT in cardiac imaging are further highlighted by its 16 cm Gemstone detector, which provides full-heart coverage in a single rotation, combined with advanced cardiac rhythm monitoring software and ultra-high-resolution imaging, the system intelligently manages arrhythmias and minimizes motion artifacts during the scanning process, this enables physicians to easily observe detailed metrics related to the heart’s structure and blood vessels, and to detect even the tiniest abnormalities such as atherosclerotic plaques, vascular stenosis,...

The 2560-slice CT technology ensures sharp, detailed coronary imaging quality that remains unaffected by arrhythmias.
With its ability to capture the heart in a single heartbeat, the 2560-slice CT technology has completely broken through the limitations of conventional CT imaging in patients with arrhythmias. As a result, patients no longer need to take beta-blockers to slow their heart rate, scan times are significantly reduced, and motion artifacts related to arrhythmias are effectively eliminated. This brings greater comfort to patients, saves time and costs, and minimizes medication-related complications — all while ensuring outstanding image quality.
According to DM.Dr Trinh Tu Tam - Head of Diagnostic Imaging and interventional Radiology Department at Hong Ngoc General Hospital: “ The 2560-slide CT system features advanced capabilities combined with Al applications, allowing it to “freeze” the coronary arteries and generate ultra-high-resolution images, enhances both the quality and contrast of the images, enhances the ability to clearly distinguish lesion boundaries and structural details, making it especially well-suited for patients with arrhythmia, tachycardia, or atrial fibrillation, while also enabling assessment of plaque composition and characteristics, as well as myocardial function. The rapid image processing also allows physicians to quickly formulate timely diagnostic and treatment strategies for cardiovascular emergencies.
Radiation dose is reduced by up to 96%, ensuring maximum safety for cardiac patients
Especially suitable for patients with arrhythmias and those with complex or multiple cardiovascular conditions, CT imaging remains a valuable tool for health monitoring, though concerns about radiation exposure still persist.
The 2560-slice CT technology, equipped with advanced radiation dose-reduction features, effectively alleviates these concerns by lowering radiation exposure by up to 96% and using up to 70% less contrast agent compared to previous-generation CT systems, ensuring maximum patient safety without compromising image quality. This is especially important for patients who require repeated imaging for ongoing monitoring, as well as for elderly individuals and those with multiple underlying health conditions.
Previous generations of CT scanners had limitations in performing comprehensive myocardial perfusion assessments due to the significantly high radiation dose required for the procedure. The 2560-slice CT technology, with an ultra-low radiation dose of under 5 mSv and rapid rotation speed, enables effective diagnosis of myocardial ischemia, as well as high-resolution monitoring and quantification of coronary atherosclerotic plaques. It also aids in detecting areas of myocardial ischemia or pulmonary infarction, allowing clinicians to develop appropriate interventional strategies.

By integrating advanced AI-powered software solutions, the system enables physicians to detect and evaluate even the smallest lesions.
The reduced radiation dose provides patients with greater peace of mind by minimizing anxiety and stress, lowering the long-term risk of radiation-related conditions, and enhancing overall safety during both diagnosis and follow-up care. Cardiac patients may undergo multiple CT scans to monitor disease progression over time. Despite the reduced radiation dose, modern technology still ensures high-quality, detailed imaging, enabling physicians to accurately diagnose cardiovascular conditions and develop appropriate treatment plans.
