China-Tanzania healthcare cooperation brings AI-powered diagnosis to patients_我的网站
一 | AI摘要 厦门农商银行总部大厦外立面全面亮相，154米高楼运用BIM技术精准管控3.6万平方米复杂幕墙安装，智慧工地系统助力年底竣工目标稳步推进。
On the island, artificial intelligence (AI) systems are helping doctors interpret medical images, while remote consultations connect local physicians with specialists thousands of kilometers away.
Bridging this distance is Yuan Gang, a radiologist with the 35th Chinese medical team in Zanzibar, who combines local imaging, cloud-based AI analysis, and real-time specialist consultations.
For years, Zanzibar's healthcare system has faced challenges in diagnosing complex diseases, particularly because of limited imaging expertise, heavy workloads, and the lack of advanced diagnostic tools, said local physician Haitham Hamudu.
Imaging interpretation, often described as the "eyes" of modern medicine, has been especially constrained by limited expertise, heavy workloads, and a lack of advanced tools, Haitham said.
By linking the hospital's imaging system with the First People's Hospital of Lianyungang in east China's Jiangsu Province, he has introduced a three-layer diagnostic approach, which includes initial reading by local doctors, AI-assisted detection and classification, and quality control through Chinese specialist review.
This hybrid model is enabling doctors in Zanzibar to access the precision and standards of top-tier Chinese hospitals without requiring patients to leave the island.
"Technology is allowing us to overcome distance and resource gaps," Yuan said. "It is not just about solving one case, but about building a system that improves care for many patients."
One of the most striking cases involved a young Zanzibari child suffering from recurrent vomiting and lethargy.
After reviewing the child's Magnetic Resonance Imaging scans, Yuan diagnosed hydrocephalus but found the underlying cause unclear. He immediately initiated a remote consultation with neuroradiology experts in the Chinese city of Lianyungang.
By jointly reviewing the imaging data and clinical records, the team identified the hidden cause, provided a precise diagnosis and treatment recommendations, giving local doctors a clear path forward and the child a renewed chance at recovery.
Beyond individual cases, Yuan has introduced AI-powered imaging tools to improve diagnostic accuracy in Zanzibar.
He said many women have dense breast tissue, making breast cancer harder to detect with conventional mammography. AI-assisted mammography now analyzes images, classifies lesions using the internationally recognized Breast Imaging Reporting and Data System, and helps doctors assess malignancy risk.
In one case, a 42-year-old woman with mild breast pain showed no obvious abnormalities on routine examination. AI, however, detected two hidden nodules and accurately classified their risk, helping doctors avoid unnecessary procedures while ensuring timely follow-up.
Similarly, AI-assisted lung imaging is improving the early detection of pulmonary nodules that are often missed in manual readings.
In one case, a 56-year-old man with a chronic cough was initially diagnosed with inflammation. Yuan's review, supported by AI analysis, identified four small nodules, including one with high-risk features, prompting closer monitoring and potentially preventing the progression of an early tumor.
Beyond diagnosis, Yuan is helping local doctors adopt AI tools, standardized reporting systems, and structured diagnostic methods through hands-on training and case-based teaching, improving diagnostic accuracy while strengthening local capacity.
The AI imaging initiative is part of a broader digital healthcare partnership between China and Tanzania's Zanzibar, Yuan said.
The hospital and its partner institution in Lianyungang have established regular remote multidisciplinary team consultations, bringing together specialists in neurosurgery, oncology, and other disciplines to jointly review complex cases and develop treatment plans.
"I have never seen this kind of consultation before," said local physician Haitham. "So many experts working together, providing practical solutions. It is very inspiring."
Bao Zengtao, leader of the Chinese medical team, said remote consultations not only improve patient care but also enhance the professional capacity of local healthcare workers.
Yuan added that the ultimate goal is to build a sustainable model that can be expanded across Africa, ensuring more patients have access to accurate diagnosis and timely treatment.

三 | 走进施工现场细看，外立面幕墙错落排布，拼接出层层叠叠的纹理，阳光从不同角度照射，层次分明。 这栋建筑是厦门农商银行总部大厦。近日，记者从承建方中建三局获悉，目前，154米高的大厦外立面已全面亮相，室内精装修完成四成，室外景观完成七成，向着今年年底竣工备案的目标稳步推进。 中建三局厦门农商银行总部大厦项目部技术总监杨闯打开电脑里的BIM（建筑信息模型），五颜六色、密密麻麻的幕墙板块在屏幕上排开，构成整栋建筑的整体造型。当杨闯点击任意一个板块，尺寸、造型、安装位置等信息立刻弹出。他说：“从生产到安装，每一块玻璃、每一根型材都有自己的‘身份证’，在模型里全部对得上。” 据介绍，该项目总共安装3.6万平方米的玻璃幕墙，包括10种不同的幕墙系统，其中，塔楼东侧双曲面造型最为复杂。此外，作为省、市级智能建造试点项目，工地现场布设了智慧监测系统，相当于给施工过程装上“眼睛”和“耳朵”，安全、扬尘、噪声都能实时掌控。（厦门日报记者 蔡绵绵 通讯员 周新 欧阳育军）。
