PURPOSE To provide a first evidence-based review of the literature on the role of fluorine-18-fluorodeoxyglucose positron emission tomography and positron emission tomography/computed tomography (FDG-PET and PET/CT) in patients with colorectal liver metastases (CRLM) undergoing selective internal radiation therapy (SIRT) with yttrium-90 ((90)Y) microspheres. METHODS A comprehensive computer l...

Laser emission from neodymium-doped glass was first produced nearly 40 years ago. Later, a crystal of yttrium, aluminum, and garnet (YAG) was discovered to be a better lasing host for neodymium. The Nd:YAG laser has since been used for a variety of medical applications, more recently, this instrument has been used for the purpose of damaging hair follicles to epilate unwanted hair. This article...

We investigated the effects of laser wavelength on the atomic, ionic, and radiative emission from laser-produced tin plasmas. For generating plasmas, planar tin targets were excited using either high intensity neodymium-doped yttrium aluminum garnet Nd:YAG, 1.06 m or carbon dioxide CO2, 10.6 m laser pulses; both are considered to be potential excitation lasers for an extreme ultraviolet EUV lit...

Yttrium aluminum garnet nanoparticles both undoped and doped with lanthanide ions (Ce, Eu, Dy and Tb) having average size around 30 (73nm) nm were prepared by glycine nitrate combustion method followed by annealing at a relatively low temperature of 800 1C. Increase in the annealing temperature has been found to improve the luminescence intensity and for 1200 1C heated samples there exists stro...

Yttrium-90 is a radioelement which has found wide use in targeted radionuclide therapy because of its attractive physical and chemical properties. Radioembolisation of hepatocellular carcinoma with radiolabelled Lipiodol is a method of choice. We have synthesised a series of alkyldithiocarbamate yttrium complexes, easily extracted into Lipiodol due to their high lipophilicity. Among the prepare...

Background: Radioactive yttrium glass microspheres are used for liver cancer treatment. These yttrium aluminum silicate microspheres are synthesized from yttrium, aluminum and silicone oxides by melting. There are two known processes used to transform irregular shaped glass particles into microspheres, these ‘spheroidization by flame’ and ‘spheroidization by gravitational fall...

Arsenic contamination in drinking water has become an increasingly important issue due to its high toxicity to humans. The present study focuses on the development of the yttrium-based adsorbents, with basic yttrium carbonate (BYC), Ti-loaded basic yttrium carbonate (Ti-loaded BYC) and yttrium hydroxide prepared using a co-precipitation method. The Langmuir isotherm results confirmed the maximu...

The best chance of cure for patients with liver cancer is surgical removal, but many tumors are too large or invasive. In addition, chemotherapy is frequently unsuccessful in this patient population. A case study is featured involving a patient determined to be a candidate for Yttrium-90 radioembolization, a minimally invasive liver-directed treatment used to target primary and metastatic liver...

Upconversion of infrared light to visible light has important implications for bioimaging. However, the small absorption cross-section of rare earth dopants has limited the efficiency of these anti-Stokes nanomaterials. We present enhanced excitation absorption and single particle fluorescent emission of sodium yttrium fluoride, NaYF4: Yb, Er based upconverting nanoparticles coated with a gold ...
