About Dr. Xu Jianrong
Dr. Xu Jianrong (许建荣) is a Professor, Doctoral Supervisor, and one of China's foremost authorities in cardiovascular imaging and advanced diagnostic radiology, based at the Department of Radiology, Changhai Hospital, Naval Medical University (Second Military Medical University). Recognized nationally and internationally as a leading expert in cardiac MRI, CT coronary angiography, and aortic imaging, Dr. Xu has established himself as one of China's most accomplished cardiovascular radiologists, with a research and clinical practice that has shaped the development and standardization of cardiovascular imaging protocols across China.
Cardiovascular imaging sits at the intersection of radiology and cardiology, requiring deep expertise in both the technical acquisition of cardiac and vascular imaging studies and the clinical interpretation of findings in the context of complex cardiovascular disease. CT coronary angiography (CTCA) has transformed the non-invasive assessment of coronary artery disease, enabling the detection and characterization of coronary atherosclerosis, stenosis, and plaque morphology without the risks of invasive catheter angiography. Cardiac MRI provides unparalleled assessment of myocardial viability, cardiomyopathy characterization, cardiac mass evaluation, and congenital heart disease anatomy that cannot be matched by any other imaging modality. Aortic CT and MRI enable precise assessment of aortic aneurysm, dissection, and congenital aortic anomalies that is essential for surgical and endovascular treatment planning. Dr. Xu's expertise spans all of these domains, making him a uniquely valuable resource for international patients with complex cardiovascular conditions requiring advanced imaging assessment.
For international patients — expatriates living in Shanghai and medical tourists from North America, Europe, Southeast Asia, and the Middle East — who require cardiovascular imaging consultation or advanced radiological assessment, Dr. Xu and Changhai Hospital's radiology department offer access to state-of-the-art cardiovascular imaging capabilities and expert interpretation at costs substantially below those of equivalent services in Western healthcare systems.
Hospital Affiliation: Department of Radiology, Changhai Hospital
Changhai Hospital (长海医霂), affiliated with Naval Medical University, is one of Shanghai's largest and most prestigious academic medical centers. Its Department of Radiology is one of the highest-volume and most technologically advanced diagnostic imaging departments in China, equipped with the latest generation of cardiovascular imaging platforms: 256-slice and 320-slice CT systems with prospective ECG-gating for low-dose CT coronary angiography and cardiac CT; 3T cardiac MRI with dedicated cardiac coils, real-time cine imaging, late gadolinium enhancement (LGE), T1 and T2 mapping, and 4D flow MRI; dual-energy CT for myocardial perfusion imaging and iodine mapping; and CT aortography with three-dimensional reconstruction for aortic disease assessment.
The department's cardiovascular imaging program is closely integrated with the cardiology, cardiac surgery, and vascular surgery departments at Changhai Hospital, enabling seamless translation of imaging findings into clinical management decisions. Dr. Xu's team provides cardiovascular imaging reporting services for the full range of cardiac and vascular conditions managed at Changhai Hospital, and maintains active research collaborations with cardiovascular imaging centers across China and internationally. The department participates in national and international quality assurance programs for cardiovascular CT and MRI, and Dr. Xu has contributed to the development of national cardiovascular imaging guidelines and standardized reporting protocols.

Why International Patients Choose Dr. Xu Jianrong and Changhai Hospital
International patients seek cardiovascular imaging consultation from Dr. Xu Jianrong and Changhai Hospital for reasons that reflect both the technical excellence of the cardiovascular imaging program and the clinical depth of Dr. Xu's interpretive expertise.
For patients with suspected or known coronary artery disease, CTCA at Changhai Hospital — performed on a 256-slice or 320-slice CT system with prospective ECG-gating for minimal radiation dose — provides a non-invasive assessment of coronary anatomy and plaque burden that is equivalent in diagnostic accuracy to invasive coronary angiography for the detection of obstructive coronary disease, while avoiding the risks and recovery time of catheter-based procedures. The availability of CT-FFR for functional significance assessment of intermediate stenoses enables a comprehensive, non-invasive coronary evaluation that guides revascularization decisions without the need for invasive pressure wire studies.
For patients with cardiomyopathy of uncertain etiology — where echocardiography has identified abnormal cardiac function or morphology but has not established a definitive diagnosis — cardiac MRI at Changhai Hospital provides the tissue characterization capability (LGE pattern, T1 and T2 mapping) that enables precise diagnosis of the underlying cardiomyopathy subtype, with direct implications for treatment selection, prognosis, and family screening. The availability of 3T cardiac MRI with T1 and T2 mapping at Changhai Hospital provides a level of myocardial tissue characterization that is not achievable with lower-field-strength systems or without dedicated cardiac MRI expertise.
For patients with aortic disease — aortic aneurysm, aortic dissection, or connective tissue disorder-related aortopathy — Dr. Xu's expertise in aortic CT and MRI interpretation and three-dimensional reconstruction provides the precise anatomical assessment that is essential for surgical and endovascular treatment planning. The cost of cardiovascular imaging and expert radiological consultation at Changhai Hospital is substantially below that of equivalent services in Western healthcare systems, and access to Dr. Xu's imaging service can typically be arranged within days through CMCS.
What to Expect at Your Consultation
Cardiovascular imaging consultations arranged through CMCS at Changhai Hospital begin with a review of all prior cardiac and vascular imaging — including echocardiography reports, prior CTCA or cardiac catheterization reports, prior cardiac MRI, and aortic imaging — as well as the patient's cardiovascular history, current symptoms, ECG, relevant laboratory results, and current medications. CMCS will arrange certified translation of all medical records and imaging reports, and coordinate the transfer of prior imaging data (DICOM files) for review where a second opinion is sought.
Dr. Xu's team will perform the requested imaging study with the appropriate protocol for the clinical indication, provide a comprehensive cardiovascular imaging report with detailed findings and clinical recommendations, and communicate directly with the referring cardiologist or cardiac surgeon regarding the imaging findings and their implications for management. A written English-language imaging report is provided after every study, and CMCS will facilitate direct communication between Dr. Xu's team and the patient's home cardiologist or cardiac surgeon for continuity of care planning.
