31. A method of imaging an osteolytic lesion, comprising:
-
injecting a contrast agent into synovial fluid in a vicinity of the osteolytic lesion;
permitting contrast agent injected synovial fluid to circulate to the lesion;
positioning an imaging device responsive to the contrast agent adjacent the vicinity of the osteolytic lesion; and
imaging the osteolytic lesion distinguished by the contrast agent from adjacent tissue. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A debridement system, comprising:
-
a fluid reservoir for a debridement fluid containing a contrast agent;
a delivery section comprising;
an expression cannula connected to the reservoir and an aspirator cannula concentric to the expression cannula; and
an imaging device responsive to contrast agent injected from the reservoir by the delivery section. - View Dependent Claims (48, 49, 50)

47. The system of claim 47, wherein the delivery section comprises a tubular conduit having a pickup end and delivery/aspirator end and first and second cannulas extending with one another longitudinally as part of the tubular conduit;
- the first cannula having at least one orifice at the delivery/aspirator end of the tubular conduit to deliver or aspirate debridement fluid to or from the distinguished lesion; and
the second cannula substantially open at the delivery/aspirator end of the tubular conduit to deliver or aspirate fluid to or from the distinguished lesion.
- the first cannula having at least one orifice at the delivery/aspirator end of the tubular conduit to deliver or aspirate debridement fluid to or from the distinguished lesion; and
