tc-99m-ec is a new renal radiopharmaceutical introduced as an alternative for tc-99m mag3. twenty-three normal volunteers and patients in different .stages of renal disease were evaluated with te-99m ec and tc-99m dtpa. the mean initial uptake of ec was significantly higher as compared to dtpa. there was a high correlation between rectangular and hand-drawn rols for kidney and background, 0.96 ...
OBJECTIVES Our purpose was to describe a novel, rapid stress thallium-201 (Tl-201)/rest technetium-99m (Tc-99m) agent myocardial perfusion imaging (MPI) protocol (Tl/Tc) with a high-speed MPI scanner and to compare this protocol with a standard rest/stress Tc-99m agent protocol (Tc/Tc) with respect to image quality and radiation dosimetry. BACKGROUND Recent advances in gamma camera technology...
tc-99m pertechnetate scintigraphy is the modality of choice for diagnosis of meckel's diverticulum. interpretation of meckel's scan identifies a focal area of radiopharmaceutical uptake in the anterior abdomen similar to normal gastric mucosa. the activity must be of the same pattern and intensity as gastric uptake. we present a 13-year-old patient with gastrointestinal bleeding and anemia. tc-...
osteoma is a benign bone-forming tumor that usually arises in the craniofacial bones and rarely in the long bones. clavicular involvement is extremely rare. we report a 51-year-old woman with osteoma of the left clavicle. radiograph of the left shoulder showed a well-defined lobulated blastic mass in the proximal and mid-portion of the left clavicle. bone scintigraphy was performed 4 hours afte...
Abstract This Review examines methods to model Josephson devices such as arrays of superconducting quantum interference (SQUIDs) and rows within two-dimensional filters or SQIFs. The emphasis is on high temperature (HTS) devices, though the techniques apply for any operating temperature. use freely-available proven software first extract all self mutual inductances thin-film device, then incorp...
