course goals
COURSE GOALS
  • Understand basics of image generation.
  • Relate imaging to gross anatomy.
  • See clinical relationship to basic science.
  • Appreciate constraints and limitations.
  • Develop imaging vocabulary.
what is diagnostic radiology
WHAT IS DIAGNOSTIC RADIOLOGY?
  • 1 year intership
  • 4 year residency
  • 1 year fellowship ?
radiologist role
RADIOLOGIST ROLE
  • Separate: Normal from Abnormal
  • Characterize / Describe: Abnormality
  • Determine: Extent (stage) of disease
  • Suggest: Diagnosis / Differential
  • Recommend: Further exams / follow-up
x ray
X-RAY
  • Discovered and named by

Dr. W. C. Röentgen at

University of Würzburg, 1895

  • Awarded first Nobel prize for physics, 1901
  • Did not patent invention

contrast radiography
CONTRAST RADIOGRAPHY
  • Injection, ingestion, or other placement of opaque material within the body.
  • Improves visualization and tissue separation.
  • Can demonstrate functional anatomy and pathology.
