  3. Please, keep some questions in mind 记住问题First. Who discovered X-ray ,and when ? 谁在何时发现了X线？ Second. What is interventional radiology?什么介入性放射学？ Third. What dose medical imaging include?医学影像学包括哪些内容？ Fourth. Which up-to-date progresses are there in medical imaging? 医学影像学有哪些最新进展？

  4. Discovery of X-ray and development of medical imaging X线的发现和医学影像学的发展Section 1 discovery of X-ray ， 第一节 X线的发现Wilhelm Conrad Rontgen，Germery physicist , 1895.11.8 伦琴, 德国物理学家, 1895.11.8

  5. diagnostic radiology, 放射诊断学， medical imaging, 医学影像学Section 2 development of medical imaging 第二节 医学影像学的发展 一、X-ray imaging X线影像学 (一) Diagnostic Radiology放射诊断学 1、 fluoroscopy 透视 :

  6. 2、 plain film 平片（thorax and abdomen)

  7. 3、contrast examination 造影检查

  8. （二）application of television system 电视系统的应用remote fluoroscopy , interventional radiology 遥控电透机、介入性放射学。 （三） application of computer 计算机的应用Produced many kinds of very important imaging techniques产生了多种极为重要的X线影像技术

  9. 1、X-ray computed tomography（CT）X线计算机体层摄影

  10. Lateral project of cranium plain film 颅骨侧位相Axial picture of cranium CT 横断面图像

  11. 2、 digital subtraction angiography (DSA)数字 减影血管造影

  12. DSA成像原理

  13. 3、digital radiography ( DR)数字X线成像three kinds of different techniques

  14. mammography：DR image DR乳腺摄影

  15. 二、non X-ray imaging 非X线影像 three kinds of important techniques 三种重要影像技术

  16. （一）ultrasonography（ USG）超声成像

  17. （二）magnetic resonance imaging（ MRI）磁共振成像

  18. MRI of brain 脑的磁共振成像

  19. （三） emission computed tomography,（ ECT）发射体层成像1、positron emission computed tomography （ PET）正电子发射体层成像 : 18F-FDG 2、single photon emission computed tomography,（ SPECT）单光子发射体层成像: 3、 PET—CT or CT — PET

  20. 单光子发射体层成像（single photon emission computed tomography, SPECT）

  21. 骨转移：热结节 甲状腺：冷结节bone metastases: hot nodus thyroid gland: cold nodus

  22. 四、interventional radiology（ IR），介入性放射学 （一）get samples for laboratory 、cytology and pathology by acupuncture under the imaging monitor and direction 在影像学的监视下采集标本（组织、体液等）做化验、细胞学和病理学检查；evidence-based medicine 循证医学 （二）treat some diseases based on the image diagnosis and under the imaging moniter and direction 在影像学诊断的基础上和监视下对某些疾病进行治疗。

  23. 五、放射学信 息系统 影像工作管理质量控制 质量保证 远程放射学 图像存档与传输系统 • Radiology information system, RIS Manage of imaging:quality control,QC quality assurance, QA TeleradiologyPicture Archiving and Communicating System, PACS

  24. ECT CT 各科终端 图文查阅 DSA USG 影像终端 影像报告 影像处理 激光打片 影像存储 远程会诊 MRI 网络中心 DR

  25. 六、最新进展 （一） magnetic source imaging（MSI），脑磁源图；magnetoencephalography MEG)脑磁图 颅脑弱磁场、屏蔽、超冷电磁测定器、测定和记录微弱脑电磁波、计算机形成图，反映脑的磁场变化，不受颅骨干扰，图像清晰，对脑外伤等多种病的诊断优于脑电图，对癫痫的定位准确性诊断达100%。

  26. （二 ）分子影像学(molecular imaging)：用影像学手段观察在活体状态下分子水平变化、对生物学行为进行定量和定性研究的学科。被美国医学会评为最有发展潜力的十个医学科学领域之一，如核素标记分子成像、MRI波谱成像、光学分子成像

  27. （三）功能成像(functional imaging)：
