  1. RADIOLOGY As Clinical Anatomy E-mail: x-ray@med.sc.edu Radiology Website: http://radiology.med.sc.edu Radiology Department: Basement of Library 733-3295 FrancisNeuffer M.D. U.S.C. School of Medicine Francis Neuffer, Radiologist

  2. WHAT IS RADIOLOGY? • MEDICAL SPECALITY THAT SUPERVISES AND INTERPRETS IMAGING STUDIES • REPORTS FINDINGS TO REFERRING PHYSICIANS • ANATOMY VS PATHOLOGY

  3. Radiologist Role • Separate: normal and abnormal • Characterize: abnormality • Determine: extent (stage) of disease • Suggest: diagnosis-differential • Recommend: further exams/follow-up

  4. 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

  5. COURSE GOALS • RELATE IMAGING TO GROSS ANATOMY • SEE CLINICAL RELATIONSHIP TO BASIC SCIENCE • UNDERSTAND BASICS OF IMAGE GENERATION • APPRECIATE CONSTRAINTS AND LIMITATIONS • DEVELOP IMAGING VOCABULARY

  6. PROJECTION VS. TOMOGRAPHIC IMAGE

  7. AP FOOT (ANTERIOR-POSTERIOR)

  8. LATERAL FOOT

  9. TOMOGRAPHIC IMAGES ARE IN A SPECIFIC PLANE AXIAL CORONAL SAGITTAL RT RT

  10. CT- EXAMPLE RT CT REFERENCE FILM Skull/brain

  11. RADIOLOGY TOOLS X- RAY ULTRASOUND NUCLEAR MEDICINE MAGNETIC RESONANCE COMPUTED TOMOGRAPHY

  12. HOSPITAL LINGO YOU WILL HEAR AND SEE THESE ABBREVIATIONS USED FREQUENTLY IN THE MEDICAL COMMUNITY X- RAY ----- PLAIN FILM SCOUT FILM RADIOGRAPH COMPUTED TOMOGRAPHY ----- CAT SCAN CT NUCLEAR MEDICINE ----- NUC MED ULTRASOUND ----- SONO SONOGRAM MAGNETIC RESONANCE ----- MR MRI

  13. HOW IS IMAGING DONE? • IONIZING RADIATION • X-ray, CT, Nuclear Medicine • SOUND WAVES • Ultrasound • MAGNETIC FIELDS / RADIO WAVES • Magnetic Resonance

  14. X- RAY • HIGH ENERGY PHOTON • --kilo electron volts • IONIZING RADIATION • EXPOSES FILM / DETECTOR • PROJECTION DATA

  15. XRAYSPLAIN FILM RADIOGRAPHY • CHEST • MAMMOGRAPHY • ABDOMEN • SPINE • EXTREMITIES, BONES & JOINTS • SKULL

  16. X - RAY -- FOUR BASIC DENSITIES • BONE • SOFT TISSUE • FAT • AIR

  17. CONTRAST RADIOGRAPHY • INJECTION, INGESTION, OR OTHER PLACEMENT OF OPAQUE MATERIAL WITHIN THE BODY • IMPROVES VISUALIZATION AND TISSUE SEPARATION • CAN DEMONSTRATE FUNCTIONAL ANATOMY AND PATHOLOGY

  18. UPPER GI – ORAL BARIUM CONTRAST (GASTRO INTESTINAL) STOMACH WITHOUT CONTRAST-plain or scout film COLON BARIUM ENEMA - RECTAL BARIUM CONTRAST

  19. INTRAVENOUS PYELOGRAM – IVP INTRAVENOUS IODINE CONTRAST WITHOUT CONTRAST-plain or scout film ARTERIOGRAM INTRAARTERIAL IODINE CONTRAST

  20. COMPUTED TOMOGRAPHY • HIGH ENERGY PHOTON • IONIZING RADIATION • EXPOSES DETECTOR • TOMOGRAPHIC DATA

  21. CT- EXAMPLE RT CT REFERENCE FILM Skull / brain

  22. NUCLEAR MEDICINE • HIGH ENERGY PHOTON • IONIZING RADIATION --radiopharmaceutical • EXPOSES DETECTOR • PROJECTION DATA • DYNAMIC / PHYSIOLOGIC

  23. NM – EXAMPLES • BONE • HEPATOBILIARY • RENAL

  24. ULTRASOUND • SOUND WAVE-high frequency • NO IONIZING RADIATION • TRANSMITTER/ RECEIVER • TOMOGRAPHIC DATA

  25. US – EXAMPLES GALLBLADDER KIDNEY OBSTETRICS

  26. MAGNETIC RESONANCE • HYDROGEN PROTONS IN A MAGNETIC FIELD • RADIO WAVE SIGNAL TRANSMISSION • NO IONIZING RADIATION • TOMOGRAPHIC DATA

  27. RT MAGNETIC RESONANCE EXAMPLES • BRAIN • SPINE • KNEE

  28. RADIOLOGY EVALUATION • MULTIPLE CHOICE - identify • LABELED IMAGES FROM FILM SETS AND LECTURE IMAGES • GROUP CASE STUDY (2)

  29. SUMMARY • TOMOGRAPHY VS. PROJECTION IMAGES • SECTION PLANES- AXIAL,CORONAL,SAGITTAL IMAGE CONSTRUCTION OF: • Nuclear Medicine • Computed Tomography • Ultrasound • X-ray • Magnetic Resonance

  30. OH… THE MANY USES OF NUC MED STUDY OF A HORSE’S _____ KING TUT MODERN IMAGING ?

  31. LUMBAR SPINE AP VIEW T-12 TRANSVERSE PROCESS L-1 SPINOUS PROCESS LAMINA SACRUM
