This document discusses techniques for visualizing soft tissues in radiography. Soft tissues have less differential attenuation compared to bones, making contrast reduced. Special techniques are needed to improve contrast and demonstrate soft tissues clearly. These include adjusting the kVp and adding filters to change image contrast. Using a normal or low kVp can help visualize certain soft tissues like adenoid and effusions more clearly. High kVp is useful for exams like BA enemas where thicker tissues are involved. Digital technology also helps improve soft tissue visibility compared to conventional radiography. Proper technique selection is important to optimize contrast and sharpness while reducing artifacts.

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

11. Soft tissue swelling

12. Normal & abnormal kagers fat pad

13. Sub normal kvp in mammo

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

15. Low kv

16. High kv

17. Need of high kv in Ba enema

18. Use of filters filters

20. Digital technology

21. Conventional vs digital mammo

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

23. • ANY QUESTIONS or DISCUSSIONS??
