Iron embedded magnetic nanodiamonds for in vivo MRI

nbsp 0183 32 In this paper we present iron embedded magnetic NDs for use as a MRI contrast agent at room temperature with an existing commercial MRI scanner In vivo experiments demonstrate that the proposed iron embedded magnetic NDs are indeed nontoxic and useful thereby opening the door on the noninvasive tracking of NDs and the immense possibilities that this brings

Comparison of liver MRI R2 FerriScan 174 VS liver MRI T2 as

nbsp 0183 32 MRI R2 and MRI T2 scan values showed a negative correlation co rrelation coefficient 0 63 p 0 01 This correlation was strong in lower LICs and progressively decreased with upper LIC values Thus a significant discrepancy was observed between median values of two MRI technologies p 0 0005 with T2 tending to underestimate iron overload especially in those with very high LIC
