ARTHROGRAPHY/TENOGRAPHY Flashcards
1
Q
ARTHROGRAPHY
A
- uses conrast injected into a joint to demonstrate abnormalities not evident in radiographs
- normal finding is smooth surface around the joint
2
Q

A
iodinated radiopaque material
3
Q

A
air
4
Q

A
- soft tissue trauma (joint capsule, ligament)
- osteochondaral defects
- loose bodies
5
Q
Abnormal findings
A
- extravasation of contrast beyond the confines of the joint
- Calcaleal fibular ligament tear w/ contrast in peroneal tendon sheath
6
Q
tenography:
A
-uses contrast injected into TENDON sheaths to diagnose inflammatory or posttraumtic conditions
7
