Noninvasive Tracking of Encapsulated Insulin Producing Cells Labelled with Magnetic Microspheres by Magnetic Resonance Imaging

Figure 5

In vitro MRI of encapsulated MM-labelled cells by 3 T scanner. (a) - and T1-weighted images of 3 μL (i) and 1 μL (ii) of naked MM solution; encapsulated unlabelled MIN6 (iii); encapsulated MM alone (iv); single capsule of encapsulated MM-labelled MIN6 (v); and clusters of encapsulated MM-labelled MIN6 (vi). (b) -weighted images of clusters (i) and single capsule (ii) of encapsulated MM-labelled human islets. The red arrows point to the discrete hypointense spots created on the agarose phantoms by MM.
