Nuclear medicine

Article Abstract:

Specialists in nuclear medicine have developed many chemicals that can be used to image various parts of the body. The most intensive use of these chemicals is in patients with heart attacks. The chemicals can be injected and then imaging instruments can measure the amount of blood perfusing through the heart. Similar techniques can be used in cancer patients to image tumors. Surgeons can use handheld detectors to help them identify areas that contain the tumor. Positron emission tomography (PET) using labelled glucose can also identify malignant tumors.

Radiation Exposure From Outpatient Radioactive Iodine ([I.sup.131]) Therapy for Thyroid Carcinoma

Article Abstract:

Many patients who take radioactive iodine for thyroid diseases can be treated on an outpatient basis. Because the iodine is radioactive, the US Nuclear Regulatory Commission (NRC) required all patients receiving certain dosages to be treated in hospitals to limit family members' exposure to the radiation. However, the agency revised this regulation in May, 1997. Researchers measured household levels of radiation in the homes of 30 patients taking radioactive iodine. All homes had radiation levels well below the level mandated by the NRC.

Association of posttherapy positron emission tomography with tumor response and survival in cervical carcinoma

Article Abstract:

The application of the positron emission tomography (PET) in the posttherapy analysis of patients with cervical carcinoma is discussed. The study shows that patients have a high chance of survival if given a 3-month posttherapy of PET with F-18 fluorodeoxyglucose (FDG).
