Injury to finger a few weeks ago. Apparent enhancement (although no pre-contrast sequence) deep to extensor tendon and a little deep to flexor tendon, but T2 signal is not bright and T1 signal is isointense. No tendon or ligament tear. Thinking post-traumatic fluid like hematoma or complex tenosynovitis but why apparent diffuse enhancement? Would getting a fat-sat pre-contrast sequence be useful to look for intrinsic T1 hyperintensity?
