UNLABELLED Peritoneal carcinomatosis can be difficult to diagnose, as CT is insensitive, with peritoneal biopsy and lavage often subject to problems of sampling error. The aim of our study was to evaluate the role of (18)F-FDG PET in detecting peritoneal carcinomatosis in patients with stomach, ovarian, and adrenal cancer and mesothelioma and to compare the results with CT scans in the same pat...

The majority of pharmaceuticals and other organic compounds incorporating radiotracers that are considered foreign to the body undergo metabolic changes in vivo. Metabolic degradation of these drugs is commonly caused by a system of enzymes of low substrate specificity requirement, which is present mainly in the liver, but drug metabolism may also take place in the kidneys or other organs. Thus...

A 31-year-old female with a history of ovarian cancer underwent an F-18 fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) scan. The PET-CT demonstrated focal nodular uptake in the subcutaneous tissue of the back adjacent to the paraspinal muscles. Color Doppler ultrasonography examination demonstrated a vascular solid mass. The patient underwent biopsy followed ...

Positron Emission Tomography (PET) is a nuclear medicine imaging technique that is widely used in early detection and treatment follow up of many diseases, including cancer. This modality requires positron-emitting isotope labeled biomolecules, which are synthesized prior to perform imaging studies. Fluorine-18 is one of the several isotopes of fluorine that is routinely used in radiolabeling o...

Soon after they were developed, very-large-scale integration circuits became an important part of the forefront of computing. The development of reliable interconnect directly on silicon wafers enabled circuits consisting of many devices to be built very easily. As the design space exploded in size with the flexibility of VLSI, an important question arose: is there any way to provide a good low...

The Integrated Avionics Systems Support Facility (IASSF) provides a simulated environment to test F/A-18 avionics, avionics software and system behaviour on the ground without the initial need for real F/A-18 flight testing. The Royal Australian Air Force (RAAF) has commissioned IASSF to allow mission critical Operational Flight Programs (OFPs) in the F/A-18 to be written, modified and tested. ...

UNLABELLED A novel PET radiotracer, Flurpiridaz F 18, has undergone phase II clinical trial evaluation as a high-resolution PET cardiac perfusion imaging agent. In a subgroup of patients imaged with this agent, we assessed the feasibility and benefit of simultaneous correction of respiratory and cardiac motion. METHODS In 16 patients, PET imaging was performed on a 4-ring scanner in dual card...
