Overview
MRI
- Magnetic resonance imaging (MRI) is specific for osteomyelitis diagnosis. This imaging modality has 90% sensitivity and 85% specificity in diagnosis of diabetic foot ulcers.[1][2]
- Usage of contrast materials such as gadolinium is not recommended in diabetic patients with renal problems due to high risk of renal failure.[3][4]
- Magnetic resonance imaging (MRI) has better efficacy in differentiating soft tissue from bone, compared to the CT scan.[2]
- Magnetic resonance angiography (MRA) can be helpful in evaluation of limb perfusion. Nevertheless it has limited spatial resolution and reports could be influenced by previous stents or implants.[5]
- Magnetic resonance angiography (MRA) has 94% specificity and sensitivity for peripheral arteries.[6][7]
- Although nephrotoxicity is lower in contrast-enhanced magnetic resonance angiography (CE-MRA), it is relatively contraindicated in patients with creatinine lower than 30 mL/min.[8]
