Positron emission tomography (PET) allows the in vivo recording of tracer compounds with respect to anatomical distribution, time course and absolute concentration. These features has proven of great value in drug development, especially in the phase of early clinical trials. PET can be used to assess the tissue kinetics of a new drug, or to evaluate a drugs interaction with a target system and thereby aid in decisions regarding dosing regimes.

UI	MeSH Term	Description	Entries
D004305	Dose-Response Relationship, Drug	The relationship between the dose of an administered drug and the response of the organism to the drug.	Dose Response Relationship, Drug,Dose-Response Relationships, Drug,Drug Dose-Response Relationship,Drug Dose-Response Relationships,Relationship, Drug Dose-Response,Relationships, Drug Dose-Response
D004344	Drug Incompatibility	The quality of not being miscible with another given substance without a chemical change. One drug is not of suitable composition to be combined or mixed with another agent or substance. The incompatibility usually results in an undesirable reaction, including chemical alteration or destruction.

D004347	Drug Interactions	The action of a drug that may affect the activity, metabolism, or toxicity of another drug.	Drug Interaction,Interaction, Drug,Interactions, Drug
D004358	Drug Therapy	The use of DRUGS to treat a DISEASE or its symptoms. One example is the use of ANTINEOPLASTIC AGENTS to treat CANCER.	Chemotherapy,Pharmacotherapy,Therapy, Drug,Chemotherapies,Drug Therapies,Pharmacotherapies,Therapies, Drug

D049268	Positron-Emission Tomography	An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower.
