Latest Positron emission tomography Stories

Elena Prieto-Azkarate, a graduate in Telecommunications Engineering at the NUP/UPNA-Public University of Navarre and member of the Nuclear Medicine Service of the University College Hospital of Navarre, has implemented 12 algorithms to process medical images produced by means of PET (Positron Emission Tomography). As she points out in her PhD thesis, read at the NUP/UPNA, the results obtained are highly promising and this technique could be very useful indeed.She has also developed a graphics...

Study reveals new hybrid molecular imaging system is as good as PET/CT gold standard for restaging patients with metastatic prostate cancer When prostate cancer makes a comeback, it becomes increasingly important to have exceptional imaging available to find all possible regions where cancer has spread to other parts of the body, or metastasized, in order to plan the best possible treatment. A relatively new imaging system that simultaneously combines positron emission tomography and...

Parallel imaging improves risk stratification and patient management and hints toward potential benefits of simultaneous PET/MR For patients with advanced breast cancer, positron emission tomography (PET) and magnetic resonance (MR) imaging can improve quality of life and survival by providing physicians with information on the effectiveness of chemotherapy prior to surgery, say researchers presenting at the 2013 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging....

Healthy test subjects with amyloid plaque were also found to have hypometabolism indicating a potential Alzheimer’s precursor Alzheimer’s disease has been linked in many studies to amyloid plaque buildup in the brain, but new research is finding a common thread between amyloid burden and lower energy levels, or metabolism, of neurons in certain areas of the brain associated with Alzheimer’s disease—even for people with no sign of cognitive decline. This is a new development in the...

Radionuclide drug treatment planning goes to the next level with 3D patient models and quantification of therapeutic dose External beam radiation treatment has long been manipulated into the unique shape of patients’ tumors for personalized cancer care. Technology providing a means of patient-specific radionuclide drug therapies has not been standardized, as it has been limited to software that requires oncologists to manually define the areas of tumors. A new “phantom” model of the...

High resolution, low dose imaging modality could diversify options for clinicians The Society of Nuclear Medicine and Molecular Imaging’s 2013 Annual Meetingmarks the unveiling of the successful application of a new preclinical hybrid molecular imaging system—single photon emission tomography and magnetic resonance (SPECT/MR)—which has exceptional molecular imaging capabilities in terms of potential preclinical and clinical applications, technological advancement at a lower cost, and...

Magnetic resonance-based wearable technology accounts for patient movement for clearer data reconstruction and fewer imaging artifacts One of the biggest hurdles of hybrid positron emission tomography and magnetic resonance (PET/MR) imaging is the prevalence of motion artifacts—blurring and ghostly visual anomalies caused by patient motion on the table during imaging. An MR technology has now been designed for PET/MR that employs tiny radiofrequency solenoids—metal coils integrated...

Molecular imaging technique detects arterial disease in the heart earlier and in finer detail than other leading imaging methods Coronary artery disease (CAD) is one of the world’s most prevalent and silent killers. Positron emission tomography (PET), which images miniscule abnormalities in cellular metabolism, can tip off clinicians about cardiac disasters waiting to happen— including sudden death from a heart attack—better than standard angiography, researchers revealed at the...

Image correction and diagnostic capabilities of two hybrid molecular imaging systems found similar in a comparative heart imaging study Just a few years ago, integrated positron emission tomography and magnetic resonance (PET/MR) imaging was found only in research institutes, but little by little the technology has expanded into clinical practice. This is especially true for cardiac indications, for which the highly sensitive soft tissue contrast of MR and the functional and metabolic...
