1. Overview
    The Center for Medical Imaging of West China Hospital of Sichuan University, the comprehensive center for medical imaging, education and research, was comprised of three departments (Radiology, Ultrasound and Nuclear Medicine), two research center (Huaxi Magnetic Resonance Research Center and the Neuroimaging Center), and two laboratories (lab of ultrasound medicine and the lab of nuclear medicine, the latter is the provincial key lab). The foundation of the Center for Medical Imaging promotes the collaboration between departments and the cultivation of specialists, and therefore sets up a comprehensive and substantial platform for the discipline of medical imaging and nuclear medicine in Sichuan University. From the year of 2007, the discipline is awarded the National Key Discipline, from a prestigious national seeding preprogram for most accomplished institution/department in the field, the only one newly awarded subsequent to other three universities. Currently, Professor Qiyong Gong is the Chair of the Center for Medical Imaging(CMI).

In the Center for Medical Imaging, medical imaging is integrated with related basic science and clinical medicine; highly qualified specialists are cultivated or enrolled from a world-wide scope. With years of development, a high-level academic group organized by specialists of medical imaging together with related specialists of clinical medicine, preclinical medicine and basic science has been built up. This group includes professors and associate professors, chairman and vice chairman of the academic committee of the Chinese Radiological Society, chief editors of national and international journals, winner of the National Award of Excellent Young Scientist, and many provincial academic leaders. Currently the Center for Medical Imaging is equipped with more than 60 sets of advanced apparatus, including dual energy CT, 320-multidetector CT, three 3T MR scanners for human beings and one 7T MR scanner for animals, PET-CT, and advanced ultrasound devices. The high-level academic group and the up-to-date equipment keep the Center for Medical Imaging at the forefront of medical imaging, education and research of West China.


2. Clinical prodctivity
    West China Hospital is currently one of the largest hospitals in the world. The clinical works of the Center for Medical Imaging also stands at the first-grade of Chinese hospitals. In the year of 2008, more than 500,000 cases received examination and therapy in the center, and the number keeps increasing by 20% each year. Medical service provided by the center covers a range from head to foot and includes multiple examination methods. Besides diagnostic imaging, interventional therapy and radionuclide therapy are also available as daily service. Many up-to-date technologies are widely employed in clinical works, including 64-MDCT imaging of coronary artery, MR angiography of multi-system, functional imaging of the brain, molecular imaging using PET-CT, et al. In particular, several aspects are considered to be our highlights:

3. Highlights on Diagnostic Imaging

1) Radiological diagnosis of disease involving the abdominal cavity and the retroperitoneal space.
2) Screening and Diagnosis of early-age hepatic cellular cancer (HCC). With refined imaging methods, the diagnostic sensitivity and specificity of HCC is improved to 92.6% and 95.8% (according to a sample of 356 cases), respectively. 
3) Application of multiple functional imaging methods including fMRI, DTI and MRS et al. to the central nervous system has broken the diagnostic ‘blind zone’ of medical imaging in many neurological and psychiatrical disorders such as depression, schizophrenia and epilepsy.
4) Screening of lung cancer with low-dose spiral CT.
5) Imaging of coronary artery using 64-MDCT.
6) Ultrasonic diagnosis of mammal mass. Owing to a database of 5,100 mammal masses, the diagnostic accuracy is improved to about 95%.
Highlights on Interventional / radionuclide therapy

1) Superselective chemotherapy or embolization of lung cancer and HCC.
2) Interventional diagnosis and therapy of cerebra vascular disease.
3) Balloon plasty of stenosis of oesophagus.
4) Interventional therapy of vertebral compression and intervertebral disk hernia.
5)Transjugular intrahepatic portosystemic shunt (TIPS).
6) Radionuclide therapy of Graves’ hyperthyroidism, DTC, bone metastases et al.
7) Ultrasound-guided interventional therapy.

4. Medical Education
The Center for Medical Imaging is one of the major center cultivating highly-qualified specialists of medical imaging and nuclear medicine. As a part of the university hospital, each department of the center had been providing education for medical students since the day of its foundation (the earliest among them is from 1924). From 1978, the discipline had been approved to award master’s degree, and from 1993 it had been approved to award doctor’s degree.

Years of cultivation and continuous enrollment have rewarded the Center for Medical Imaging with highly qualified faculty members, including 12 doctor advisors and 25 master advisors. From 2001 to 2006, 76 doctoral students and 126 master students were enrolled and most of them had been awarded academic degree. In addition, 3 post-doctoral fellows have finished their researches in the center. Among them there is a nominee of the Young Investigator Award of the 2008 ISMRM, which is the first one in Chinese students for the award. From 2001 to 2006, postgraduate students had published more than 20 papers on the SCI Journals and had attended more than 20 international meetings such RSNA and ISMRM for oral presentation.

The Center for Medical Imaging initiated professional education of medical imaging technology as the first department of medical imaging technology in China was set up in 1997. And from the year of 2005, the center initiated the standardized 2-year training of medical imaging technologists.

The Center for Medical Imaging also initiated the standardized 5-year training of residents of medical imaging and nuclear medicine since 2003. Residents admitted in the residency come from various provinces of China.

Since the year of 2004, the Huaxi-Jefferson ultrasound education center was setup based on the cooperation between the department of ultrasound and the American Thomas-Jefferson ultrasound education center. Until now up to 370 ultrasound specialists have received training in this center. 

The department of nuclear medicine is the training base of professional doctors of the Ministry of Health of China. Training course of radionuclide therapy has been held for 10 times and up to 1,000 professional doctors were trained in the center.
In addition, the Center for Medical Imaging also provides English educational service for oversea students from India, Pakistan, Nepal et al.

5. Research
The inter-discipline cooperation between medical imaging and related science enables the faculty to carry out in-depth scientific researches. Owe to years of efforts, the center has made some achievements regarded as the milestone. In the year 2002, this discipline was awarded the Provincial Key Discipline, and in 2007 it was awarded the National Key Discipline.

Research Funds: Many national research projects have been brought out in the Center for Medical Imaging, including the National Research and Development Program (known as the ‘863’ project), the National Key Basic Research Development Plan (known as the ‘973’ project), the National Natural Science Foundation Committee (NSFC). Total funds are up to 10.36 million RMB. At present many ‘863’ and ‘973’ projects and NSFC-British Royal Society collaboration projects are being carried out in the center. The total funds are more than 6.00 million RMB. 

Scientific publications: more than 600 scientific papers were published on national and international core journals. 8 monographs and 10 textbooks in which faculty members participated as editors-in-chief were published. Among them, the research paper ‘High-field MRI reveals an acute impact on brain function in survivors of the magnitude 8.0 earthquake in China’ conducted by Prof. Qiyong Gong was published on the 2009 PANS and was cited and reported by mass media. And the textbook ‘Medical Imageology’ whose chief-editor is Prof. Xiangping Zhou, is awarded the 2009 ‘elite textbook’ by the Ministry of Education.



6. Scientific awards and patents

Many scientific awards were conferred, including: National Third-grade Award for the Progress of Science and Technology, the Second-grade Award for Progress of Science and Technology conferred by the Ministry of Health, the First, Second and Third-grade Provincial Award for the Progress of Science and Technology, and the Second-grade Award for the Progress of Science and Technology conferred by the Chinese Medical Association.
