Nuclear Medicine News and Research

RSS

Nuclear medicine is a branch or specialty of medicine and medical imaging that uses radioactive isotopes (radionuclides) and relies on the process of radioactive decay in the diagnosis and treatment of disease. In nuclear medicine procedures, radionuclides are combined with other chemical compounds or pharmaceuticals to form radiopharmaceuticals.

Cyr61 gene transfer appears potent in stimulation of myocardial angiogenesis

French scientists, examining the possibility of using nuclear medicine with gene therapy to fight heart diseases, reported their findings at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Patients who need PET/CT scans should avoid drinking coffee

Patients who need a positron emission tomography (PET)/computed tomography (CT) procedure to evaluate known or suspected malignancies should lay off the java, according to research by Medhat M. Osman, M.D., Ph.D., assistant professor in the department of internal medicine's division of nuclear medicine and director of PET at Saint Louis University Hospital.

Research urges a new approach to cancer detection

A few years ago, Medhat Osman, M.D., Ph.D., had a patient who was scanned due to a suspicion of lung cancer using positron emission tomography (PET) and computer tomography (CT) technology. The scan came back negative, but the patient then complained of a problem with his leg.

Whole-body positron emission tomography/computed tomography scans may help physicians identify malignant cancerous tumors

A team of researchers at Johns Hopkins Medical Institutions in Baltimore, Md., reports that whole-body positron emission tomography/computed tomography (PET/CT) scans may help physicians identify new, unexpected malignant cancerous tumors in patients, according to an article in the May issue of the Society of Nuclear Medicine’s Journal of Nuclear Medicine.

Isotopes for society

The nucleus of an atom contains protons and neutrons. However, some atoms of the same chemical element can have varying numbers of neutrons, giving so-called isotopes of that element.

Use of positron emission tomography may eliminate more strenuous drug development trials with animals

A number of articles explore the use of positron emission tomography (PET) and small animal imaging—nonsurgical techniques that open the door to understanding and treating human diseases—in the April issue of the Society of Nuclear Medicine’s Journal of Nuclear Medicine.

Pet scanning could cut use of angiograms and bypass surgery, as well as patient costs

Using positron emission tomography (PET) scanning rather than other types of imaging as the first tool to diagnose heart-vessel blockages is more accurate, less invasive and saves dollars, a study by a University at Buffalo team has shown.

PET and CT scans provides accurate detection and localization of foot infection in diabetic patients

Pioneering research with combined positron emission tomography (PET) and computed tomography (CT) scans provides accurate detection and localization of foot infection in diabetic patients, according to an article in the March issue of the Journal of Nuclear Medicine.

New way to assess the potentially damaging effects of prenatal drug exposure

Scientists have demonstrated a new way to assess the potentially damaging effects of prenatal drug exposure--a technique that could also be used to monitor a fetus's response to therapeutic drugs--using sophisticated, noninvasive medical imaging tools.

Nicotine may hold promise in the early diagnosis of Alzheimer's disease

The chemical nicotine--a main ingredient in tobacco--may hold promise in the early diagnosis of Alzheimer's disease, give insight into therapeutic interventions for nicotine addiction and possibly complement the diagnosis of certain forms of lung cancer, according to a study in the January issue of the Society of Nuclear Medicine's Journal of Nuclear Medicine.

New insight into how tumor cells can become resistant to anti-cancer therapy

The scientists observed that a protein called P-glycoprotein (P-gp), which causes resistance to chemotherapy in many tumor types, is able to physically “jump” or transfer between tumor cells and retain its functional properties, protecting otherwise sensitive cells from the effects of anti-cancer treatment in vivo and in vitro.

Study identifies potentially valuable applications for new drug Nifrolidine

Along with aiding efforts to study addicted smokers, a new drug that attaches only to areas of the brain that have been implicated in nicotine addiction may help studies of people battling other disorders such as Alzheimer’s disease and schizophrenia.

AIDS breakthrough - vaccine strengthens the body’s immune system againts HIV

A Hadassah University Medical Center research team has developed a vaccine that significantly strengthens the body’s immune system against the autoimmune sequela of HIV infection, a breakthrough that could dramatically make an impact in the treatment of AIDS patients.

Combined positron emission tomography and computerized tomography can help diagnose hidden recurrent cancer

Combined positron emission tomography and computerized tomography (PET/CT) can help diagnose occult (hidden) recurrent cancer, possibly a cancer patient's greatest post-treatment fear, report a team of Israeli physicians in the December issue of the Society of Nuclear Medicine's "Journal of Nuclear Medicine."

Using precise, radioactively labeled genetic probes, researchers study cancer gene activity from outside the body

Using precise, radioactively labeled genetic probes, researchers at Jefferson Medical College have seen cancer gene activity from outside the body in laboratory mice. The probes, which work by attaching to genetic codes copied from an active cancer gene, may someday aid physicians and scientists in cancer detection and in determining the appropriate treatment for a cancer.

Thyroid treatments can set off radiation detectors

Medical procedures such as iodine therapy, a popular thyroid treatment, can result in patients triggering radiation detectors for up to three months after treatment, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
