Sensitivity of multimodality imaging of labeled human islets. (a) 1H MR imaging of Feridex®-labeled islets at 50 islets/ml gel demonstrates clear detection of hypointense single islets (inset). (b) Micro-CT of 10 PFOB-labeled islets. (c) 9.4 T 19F MR imaging of PFPE-labeled islets. From left to right, phantom contains 10, 50, 100 and 200 islets. (d) 3 T 19F MR imaging of PFPE-labeled islets. On top from left to right phantom containing 500, 1000, 2000, 3000 and 4000 μg of PFPE. On bottom from left to right 500, 1000, 1500, 2000 and 2500-PFPE labeled islets. (e) Ultrasound imaging of PFOB-labeled islets. From left to right, phantom contains 10, 50, 100 and 200 islets. (f) In vivo ultrasound imaging of PFOB-labeled islets transplanted intramuscularly in a nude mouse with point injections of 1, 5, 10 and 25 islets.
