Article Title : The Effect of Inversion Time on the Relationship Between Iron Oxide Nanoparticles Concentration and Signal Intensity in T1-Weighted MR Images

Master Auther :

Journal Title and Number : Iran J Radiol. 2014 May; 11(2): e12667.

summary : Background: Magnetic nanoparticles have been widely applied in recent years for biomedical applications. Signal intensity (SI) of magnetic resonance (MR) images depends on the concentration of nanoparticles. It is important to find the minimum concentration of iron oxide nanoparticles that produces maximum SI and determines the minimum injection dose for clinical studies. Objectives: This study was performed to determine the relationship between the iron oxide nanoparticle concentration and SI using inversion recovery (IR) sequence in T1-weighted MR images.

summary : Ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles–based magnetic resonance imaging (MRI) have offered new promise for early detection of lymph nodes and their metastases. These nanoparticles are taken up by macrophages in normal lymph nodes and produce signal changes based on susceptibility artifact and dipolar relaxation. The effects of MR protocols and their parameters on artifact size and detection sensitivity have been studied before. In this study USPIO nanoparticles were used as MRI contrast agent, and their detection sensitivity in axillary lymph nodes was evaluated using earlier defined pulse sequences. The minimum amount (dose) of USPIO nanoparticles that delineates lymph nodes of various sizes using susceptibility-based gradient echo pulse sequences was also determined. It was found that a dose administration of as low as 0.028 mg iron (Fe)/kg for subcutaneous injection and 0.16 mg Fe/kg for intravenous injection can be used to visualize axillary lymph nodes when a sensitive MR protocol is employed.
