1. SOFT TISSUE RADIOGRAPHY
PPT 1ST
By Virendra Kumar Maurya

3. To assess the soft-tissue using the low
energy x ray photon and without using
of contrast media, is called soft tissue
radiography .
For e.g. muscle, skin, and
subcutaneous and glandular tissues.

4.  Soft-tissue radiography is the term generally
used for radiography of muscle, skin, and
subcutaneous and glandular tissues without
the use of contrast media.

5.  Radiographic contrast: use of appropriate
exposure technique, and reduction of
scattered radiation;
 Image sharpness: immobilization, small focal
spot, film or film/ screen combination
chosen according to exposure technique;
 Avoidance of artefacts: non-screen technique
or scrupulously cleaned screens, avoidance
of dressings, and avoidance of folds in the
skin or in the patient’s gown.

6.  This category may be divided into three
subcategories:

7.  Use of a normal technique for the part being
examined when air shadows or fat pads.
 Effusion in a synovial cavity causing a filling
defect in a fat pad adjacent to a joint;
 Enlarged adenoids causing a filling defect in
the air contained in the nasopharynx.

8.  Use of two or more films e.g.:
 Facial bones, nasal bones and soft tissues of
the face;
 Calcification of tendons and bony detail of
the shoulder joint.

9.  Use of a wedge filter, e.g.
 Cephalography to demonstrate bony detail
of the skull and facial bones along with the
soft-tissue outline of the face on one film.

10.  subnormal kVp, low kVp and high kVp.

11.  subnormal kVp:-This term is used when the
kVp employed in less than 45kVp, which is
the lowest useful kVp available on many X-
ray units.
 Low kVp:- This term is used when the kVp
employed is 15–20kVp less than normal for a
similar projection of the area being
examined.
 High kVp:- 20 kVp more

12.  Digital imaging technology facilitates the
application of ‘windowing’ the acquired
image to visualize soft tissue areas even
when normal kVps are employed.

13.  Clack positioning
