Figure 6From: A new ex vivo method to evaluate the performance of candidate MRI contrast agents: a proof-of-concept study Short name: Gold (Au) biodistribution as measured by ICP-MS 24Â h post-administration of GNP (E _2). Detailed legend: Gold (Au) biodistribution as measured by ICP-MS 24Â h post-administration of GNP (E_2). Inset shows tumor Au accumulation at a different scale, compared to element concentrations in plasma and contralateral brain. The difference of Au accumulation between contralateral brain and tumor is nearly significant for GNP (E-2), p =0.056. Values are shown as mean parts per million (ppm) and SD (bar). Statistical comparisons correspond to unpaired t-tests.Back to article page
