UIH(SH:688271) Ren Min Ri Bao·2025-09-12 22:16Core Insights - The article discusses the advancements in photon counting spectral CT technology, highlighting its superior resolution and reduced radiation exposure compared to traditional CT scans [1][4]. Group 1: Technology Advancements - The new photon counting spectral CT has a pixel size of 0.2 mm, which is 1/9 of the pixel area of traditional CT, allowing for detailed visualization of small structures such as the cochlea and vascular patterns during heartbeats [1][2]. - The radiation dose for patients has been reduced by 60% to 70%, with some examinations achieving a reduction of up to 90%, providing clearer diagnostic information while minimizing patient exposure [1]. Group 2: Clinical Applications - The technology is particularly effective in early detection of lung nodules, assessing coronary artery calcification risks, and analyzing tumor characteristics, thus aiding in determining whether a tumor is recurrent, metastatic, or benign [3]. - The photon counting spectral CT is expected to become a mainstream diagnostic tool, with significant potential for further research across various diseases [4]. Group 3: Development and Collaboration - The development of this technology involved collaboration among multiple institutions, including U-Medical, Zhongshan Hospital, and Ruijin Hospital, under a national key research program [4]. - The article emphasizes the ongoing evolution of this technology, indicating that it will continue to improve and play a crucial role in patient recovery and diagnosis [4].
