can the chemicals in the toy result in an exposure, and is this exposure associated with a health risk.  In toxicology, this is described in the following equation: Risk = Exposure x Hazard

hildren under about 3 years of age often mouth toys and other objects.  Mouthing presents a high opportunity for exposure to chemicals, as well as accidental swallowing.  For example, some toy jewelry contains levels of lead and cadmium.  While these toys may be safe if they are only touched (lead and cadmium don’t easily penetrate human skin), they may not be safe if mouthed, since lead and cadmium dissolve in saliva and then get swallowed.

MR Angiography: MR angiography can provide diagnostic images of the vascular system without the need for arterial puncture or catheters.  A quick, non-invasive means for evaluating most vascular problems is now available. MR angiography is used to evaluate aneurysms and other malformations in blood vessels, to screen for arterial diseases and abnormalities in the body’s circulating system.  Intravenous Gadolinium contrast is used to visualize abnormalities in the neck, abdomen, renal system and extremities. Non-Invasive Prostate Imaging: MRI can provide extremely accurate information for the diagnosis and pre-treatment planning of prostate cancer.  In the past, this predominantly involved the use of a coil placed within the rectum.  Now, with advances in coil technology and software, these studies can be performed with a coil placed over the pelvic area.  These new coils provide images of similar resolution without the discomfort of the endo-rectal coil. Breast MRI: Breast MRI has emerged as a valuable addition to conventional imaging modalities in the detection of primary and recurrent breast cancer.  It is mainly used in cases that are difficult to evaluate with mammography or ultrasound, or where there are conflicting findings between these two modalities.  MRI also allows early diagnosis of primary and recurrent breast cancer in high-risk patients.

sure that drugs marketed in this country are safe and effective. CDER does not test drugs, although the Center's Office of Testing and Research does conduct limited research in the areas of drug quality, safety, and effectiveness.CDER is the largest of FDA's five centers.   It has responsibility for both prescription and nonprescription or over-the-counter (OTC) drugs. For more information on CDER activities, including performance of drug reviews,  post-marketing risk assessment, and other highlights, please see the CDER Update: Improving Public Health Through Human Drugs1 The other four FDA centers have responsibility for medical and radiological devices, food, and cosmetics, biologics, and veterinary drugs. Some companies submit a new drug application (NDA) to introduce a new drug product into the U.S. Market.  It is the responsibility of the company seeking to market a drug to test it and submit evidence that it is safe and effective. A team of CDER physicians, statisticians, chemists, pharmacologists, and other scientists reviews the sponsor's NDA containing the data and proposed labeling2.
