soft tissue radiography

radiographic techniques of imaging soft tissues

1. SOFT TISSUE RADIOGRAPHY WADP DARSHANA RADIOLOGIC TECHNOLOGIST-SRI LANKA

2. What are soft tissues? Tissues other than bones

3. Why we need special techniques to demonstrate soft tissues? Differential attenuation is less in soft tissues. So the subject contrast is less in soft tissues.

4. Difference densities according to differential attenuations

5. How to change the contrast of radiographic image? By Changing Kvp By adding filters

6. Use of normal Kvp Air and Fat are low dense and give blackish appearance than other tissues if we use normal kvp .

7. Enalarged adenoid is seen in nomal neck exposures ??????????????

8. Knee effusions seen in normal Kvp

9. lipohaemoathrosis

10. Soft tissue swelling

11. Normal & abnormal kagers fat pad

12. Sub normal kvp in mammo

13. Skull normal exposure vs soft tissue exposure………. use profile projections( tangenital )

14. Low kv

15. High kv

16. Need of high kv in Ba enema

17. Use of filters filters

18. Digital technology

19. Conventional vs digital mammo

20. To demonstrate soft tissues successfully; special attention must be given to; -Radiographic contrast -Image sharpness -Avoidance of artifacts

21. ANY QUESTIONS or DISCUSSIONS??
