Medical imaging of a subject requires a strong signal from the target area in order to successfully measure, display, and image the tissue. Typically, various contrast agents are used to create this signal. Liposomes can be used as carriers for these contrast agents, which would allow for this same intense signal. Specifically, liposomes have properties that can easily be controlled as well as various other useful characteristics. The advantages of liposomes in X-Ray, ultrasound, nuclear, and MRI diagnostic imaging over traditional tissue-selective contrast media are their high capacity loading system, good tolerability, and tissue selectivity. Typically, the target organs of these liposomes are the liver and the spleen. [Citation 47] [Citation 48]

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The contrast agents used in this MRI image show clearly defined areas of the brain. The use of liposomes can help improve this contrast.
