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.

Dilon Technologies delivers enhanced imaging capabilities

Dilon Technologies, Inc., the leader in molecular breast imaging, today announced the release of the newest Dilon 6800 Software update including enhancements for both breast and general nuclear medicine applications image processing. The new software functionalities complement the Slant15 Collimator for breast imaging and the Low Energy High-Resolution (LEHR) Collimator for general nuclear medicine applications, both released earlier this year as purchase options for the Dilon 6800 gamma camera.

Medical isotope shortage hurts hospitals and disrupts medical tests

Reuters reports that "a North American shortage of medical isotopes has forced many U.S. hospitals to begin rationing scores of diagnostic tests, and doctors said on Friday they see no quick solution."

Non-toxic radioactive patch successfully treats skin cancer

A new study shows that a radioactive skin patch can safely and successfully treat basal cell carcinoma, one of the most common types of skin cancers, according to researchers at the SNM's 56th Annual Meeting. The skin patch, which delivers the radioactive phosphorus-32, is nontoxic and could be an excellent alternative to surgery or radiotherapy in cases where carrying out these treatments is difficult.

Positron emission tomography scans may improve the accuracy of dementia diagnosis

A new study shows that the use of positron emission tomography (PET) scans may improve the accuracy of dementia diagnoses early in disease onset for more than one out of four patients. The results were presented at SNM's 56th Annual Meeting.

Effect of 18F-FDG PET/CT in esophageal cancer patients with early recurrence lesions

In the initial staging of esophageal cancer, preoperative PET scan may be useful in detecting additional cases of metastatic disease before costly and toxic definitive therapy.

Accurate assessment of heart disease leads to earlier, more aggressive therapy

In a study comparing the ability of various medical techniques to accurately determine the extent of heart disease and stratify patients according to disease severity, researchers found that myocardial perfusion testing with gated single photon emission computed tomography (gated SPECT) was a more accurate predictor of prognosis in chronic ischemic heart disease (IHD)-a painful condition caused by a temporary reduction of oxygen-rich blood to the heart.

Study tracks increasing use of CT on pregnant women

Researchers have found that over a 10-year period radiologic exams on pregnant women have more than doubled, according to a study published in the online edition of Radiology.

Radioimmunotherapy shows promise for HIV infection and viral cancers

Scientists at Albert Einstein College of Medicine of Yeshiva University have piggybacked antibodies onto radioactive payloads to deliver doses of radiation that selectively target and destroy microbial and HIV-infected cells.

PET/CT may improve prognosis for patients with inflammatory breast cancer

In the largest study to date to evaluate fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT) in the initial staging of inflammatory breast cancer (IBC), researchers were able to identify the precise location and extent of metastasis (spread of disease), offering the potential for a better prognosis for patients with this rare, but aggressive form of breast cancer.

People without heart disease symptoms should use caution in obtaining cardiac imaging exams

At the radiation dose levels used in cardiac imaging exams, such as cardiac CT or nuclear medicine scans, the risk of potentially harmful effects from ionizing radiation are low.

Molecular imaging enables earlier, individualized treatment of thyroid cancer

In a study to determine the diagnostic value of molecular imaging in nodal staging of patients with thyroid cancer, researchers were able for the first time to accurately distinguish between cancerous cells in regional lymph nodes and normal residual thyroid tissue directly after surgery.

Discovery of molecule that targets brain tumors

UC Davis Cancer Center researchers report today the discovery of a molecule that targets glioblastoma, a highly deadly form of cancer.

Symptoms of fibromyalgia related to dysfunction in parts of brain where pain is processed

Using single photon emission computed tomography (SPECT), researchers in France were able to detect functional abnormalities in certain regions in the brains of patients diagnosed with fibromyalgia, reinforcing the idea that symptoms of the disorder are related to a dysfunction in those parts of the brain where pain is processed.

Methamphetamine enters brain quickly and lingers

Using positron emission tomography (PET) to track tracer doses of methamphetamine in humans' brains, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory find that the addictive and long-lasting effects of this increasingly prevalent drug can be explained in part by its pharmacokinetics - the rate at which it enters and clears the brain, and its distribution.

Ongoing debate: The future of non-invasive cardiac imaging

Imaging has gained attention in many areas of medicine but its relevance and importance in clinical cardiology cannot be underestimated.

Dual-mode nanoparticles image tumors using MRI and PET

Medical imaging represents one of the most used and useful procedures in the oncologist's diagnostic toolkit, even though each of the most useful techniques-magnetic resonance imaging (MRI), computerized tomography x-ray imaging (CT), and positron emission tomography (PET) scanning-has its own set of limitations.

Radioactive "tag" added to formaldehyde helps monitor body chemistry, disease

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a simple, fast method for adding a radioactive "tag" to formaldehyde, a common organic chemical.

Individualized therapies for non-Hodgkin's lymphoma identified with PET

Positron emission tomography (PET) could be an important tool for identifying non-Hodgkin's lymphoma patients who are likely to respond well to treatment with 90 ibritumomab tiuxetan (IT)-the first radioimmunotherapy treatment approved for use by the U.S. Food and Drug Administration, said researchers at the Society of Nuclear Medicine's 55th Annual Meeting.
