• INCLUSION CRITERIA:

Any normal volunteer above the age 18 who is capable of giving informed consent will be included.

EXCLUSION CRITERIA:

A subject will be excluded if he/she has a contradiction to MR scanning.

1. Brain aneurysm clip

4. Cochlear implant
5. Ocular foreign body (e.g. metal shavings)
6. Insulin pump
7. Pregnant women (when uncertain, subjects will undergo urine or blood testing).
8. Kidney
9. Paralyzed hemidiaphragm
10. Morbid obesity
11. Claustrophobia
12. Any condition in the PI's judgement which present unncessary risk

EXCLUSION CRITERIA FOR GADOLINIUM ENHANCED STUDIES:

1. Lactating women
2. Subjects with hemoglobinopathies
3. Asthma
4. Renal or hepatic disease

Subjects will be excluded if it is deemed that they have a condition that would preclude their use for technical development (e.g. paralyzed hemidiaphragm, morbid obesity, claustrophobia etc.) or present unnecessary risk (e.g. pregnancy, surgery of uncertain type, etc.).

Lactating women and subjects with hemoglobinopathies, asthma, or renal or hepatic disease will be excluded from studies involving the adminstration of contrast agents.
