Researcher evaluated the ability of different (18F) fluoro-deoxy-d-glucose (FDG)-positron emission tomography (PET)-based and magnetic resonance (MR)-based parameters to identify prevertebral space (PVS) infiltration by hypopharyngeal carcinoma.
Antibodies and their derivatives radiolabelled with positron and gamma emitting radiometals enable sensitive and quantitative molecular Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT) imaging of antibody distribution in vivo.
Lymph node detection in prostate cancer is challenging and critical for determining treatment policy. Choline PET/CT (positron emission tomography/computed tomography) and magnetic resonance imaging (MRI) have been used for the evaluation of lymph node metastasis in patients with prostate cancer for the past decade. However, only limited patients underwent direct comparison studies.
In nuclear medicine, the goal is to keep radiation exposure at a minimum, while obtaining quality images. Optimal dosing for individual patients can be difficult to determine. That's where 3D-printed organ models of varying size and shape could be of great use.
Already affecting more than five million Americans older than 65, Alzheimer's disease is on the rise and expected to impact more than 13 million people by 2050. Over the last three decades, researchers have relied on neuroimaging brain scans such as magnetic resonance imaging (MRI) or positron emission tomography (PET) to study Alzheimer's disease and other neurodegenerative diseases.
Researchers at Johns Hopkins Medicine have identified in live human brains new radioactive “tracer” molecules that bind to and “light up” tau tangles, a protein associated with a number of neurodegenerative diseases including Alzheimer’s disease and other related dementias
New research on prostate cancer staging shows that PSMA-targeted PET/MRI performs equally as well as currently used predictive tools to determine the risk for advanced disease.
Disturbance of gonadotropin-releasing hormone (GnRH) signaling is implied in a variety of human diseases spanning from reproductive diseases, hormone-dependent oncological diseases, and neurodegenerative diseases. GnRH receptor (GnRH-R) play a central role in this context and have consequently attracted considerable interest as therapeutic targets
Imagine a barking dog, a furry spider or another perceived threat and your brain and body respond much like they would if you experienced the real thing. Imagine it repeatedly in a safe environment and soon your phobia—and your brain's response to it—subsides.
Integrated positron emission tomography/computed tomography (PET/CT) is increasingly used in diagnosis, staging, therapy assessment, and follow-up of cancer patients. The study conducted to perform a systematic review of the effect of time interval on 2-deoxy-2-[18F] fluoro-D-glucose (18F-FDG) uptake in normal organs.
In the diagnosis of Alzheimer's disease and the search for effective treatments, tau tangles in the brain have joined amyloid build-up as markers of the disease and potential therapeutic targets. In the December issue of The Journal of Nuclear Medicine, the featured article of the monthly reports on the identification of a promising second-generation positron emission tomography (PET) tracer for imaging and measuring tau pathology
Although relatively rare in the United States, and accounting for fewer than 5% of tuberculosis cases worldwide, TB of the brain—or tuberculosis meningitis (TBM)—is often deadly, always hard to treat, and a particular threat to young children. It may leave survivors with lifelong brain damage
