1. SOFT TISSUE RADIOGRAPHY
PPT 2ND
By VIRENDRA KUMAR MAURYA

2.  Lesions Demonstrated By Air
 Lesions demonstrated by fat
 Calcifications in soft tissue
 Bone in adjacent soft tissues

8.  Soft-tissue lesions may be demonstrated by
air in body cavities, e.g. enlarged adenoids
encroach on the posterior nasopharyngeal air
space demonstrated on a lateral projection
of the neck. After adenoidectomy, there is no
longer soft-tissue encroachment on the air
space.

10.  Adenoids are tiny glands with a big job. They
help keep the child healthy until their body
finds other ways to fight off germs.

14.  Centering
 Technical factor

15.  Fat has a lower attenuation coefficient than
other soft tissue and shows as a higher
optical density on the radiograph.
 Effusion in a synovial cavity may cause a
filling effect in a fat pad adjacent to a joint.
 A horizontal central ray technique is used.

17.  Calcifications in limbs,
 calcifications of arteries,tendons and
ligaments, are usually best demonstrated by
using a low kVp exposure technique.

18.  Rheumatoid arthritis, gout, and
osteomyelitis, there may be soft-tissue
swelling and calcification. It is, therefore,
essential that the kVp is sufficient to
demonstrate both bone and soft-tissue
structures.
