Final answer:
Contrast agents are liquid suspensions that can be injected into the patient's circulation to help reduce echogenicity. They are used in techniques like magnetic resonance imaging (MRI) to obtain detailed images of soft tissues. Injecting an MRI contrast agent selectively affects the magnetic properties of water and allows doctors to see different tissues separately.
Step-by-step explanation:
The liquid suspensions that can be injected into the patient's circulation to help reduce echogenicity are contrast agents.
Contrast agents are advanced imaging platforms that are loaded inside theranostic liposomes. They improve label efficiency and help in obtaining detailed images of soft tissues, such as internal organs, in techniques like magnetic resonance imaging (MRI). MRI is based on the magnetic properties of hydrogen atoms in water, which is a major component of soft tissues. Injecting an MRI contrast agent selectively affects the magnetic properties of water and allows doctors to see different tissues separately.
