Nanoparticles may be utilize as a new class of uniform, biodegradable and non-toxic superparamagnetic contrast agents (Fe3O4). The preparation process of these particles is simple, does not involve any toxic material and the yield is close to 100%. The particles are usually of varying sizes from several to several hundred nanometer. They are irregular in shape and highly light-absorbing. They have no magnetic hysteresis at ambient temperatures, which is characteristic of superparamagnetic materials. Each magnetic nanoparticle is composed of a very thin organic nucleus (5-10%) and a thick shell of magnetite.
Different techniques were established for coating these magnetite nanoparticles with several functional and biocompatible polymers. Both the coating and the magnetite production processes are controllable, so that it is possible to prepare particles with a specific size of each particle component as well as particles coated with protein ligands for tissue specific imaging applications.

Molecular Imaging
 
Molecular Imaging is a new diagnostic discipline to visualize biological processes.
Molecular magnetic resonance imaging (mMRI) offers the potential to image tissues at the cellular and subcellular level. Targeted MR contrast agents enhance the diagnostic specificity and range of molecular magnetic resonance imaging.
Other modalities that can be used for noninvasive molecular imaging:
Ultrasound;
optical imaging;
positron emission tomography (PET);
single photon emission computed tomography (SPECT).

Generic name: Liposomes, central moiety: different, contrast effect: paramagnetic, distribution: different
Liposomes are lipid containing nanoparticles, or fat molecules, surrounding a water core. Liposomes were the first type of nanoparticles created to be used as carriers for lipophilic MRI contrast agents with novel characteristics.
Liposomes loaded with gadolinium-containing chelates have potential as blood pool agents, caused by modifications of the surface (e.g., with polyethylene glycol) leading to longer blood retention times.
The incorporation of contrast agents into either the the bilayer membrane or the aqueous inner cavity is possible. These MRI contrast agents has been used to image the lymph nodes using liposomes containing Gd-DTPA as well as dextran coated iron oxide particles.
To image the liver or the hepatobiliary system, liposomes containing Gd-HPDO3A, or MnDPDP, have been tested.
Liposomes containing gadolinium were conjugated to antibodies and targeted to a specific organ system.
A method of targeting tumors with ultrasound that also uses MRI to watch the cell destroying, uses liposomes loaded with cytotoxic drugs and also with gadolinium to make them show up in MRI. As well as used as an imaging technique, ultrasound can also be used to destroy cancer cells. Once the drugs have been administered, focusing the ultrasound on the target area makes blood vessels permeable. The liposomes leak out of the blood vessel into the target area, watched by MRI, where the cytotoxic drug can then go to work.
