Imaging in wound care
Blood flow assessment
Arteriogram
Indications: observational or interventional. Can observe, use a balloon, or deliver a drug
-
Ultrasound
Indications: assess blood flow, including direction and speed as well as waveform analysis. Assess for DVT and incompetent valves
Pros: non-invasive, real time. Cons: hard to interpret without advanced training
CT and MR Angiogram
Indications: Generally used to identify areas of stenosis. Can do 3D imaging so can see in relation to other structures
Pros: 2D/3D imaging can be done with/without bone subtraction. Cons: CT requires iodinated contrast. MR can be with or without contrast, but CT is more efficient and provides better resolution
Foreign body assessment
X-ray: Will generally be the first imaging since it is least expensive. Does still have radiation risk
Excellent to identify metal: (bullets, needles, wire, etc)
Limitation: Not good at assessing wood and other radioluscent materials that look similar to tissues.
Ultrasound: Is good at detecting superficial FBs. Good alternative for detecting wood. FBs appear bright
Pro: Non-invasive, no radiation. Con: Harder to interpret
CT and MRI: More useful for deeper foreign bodies. If FB suspected, but x-ray (-) that is when they may do a CT or MRI. Another use is in chronic draining wounds to identify the cause
