Small scale manufacturing and scintigraphic detection of pellet formulations
… of radioisotope required for manufacturing for scintigraphic studies.Extrusion-spheronisation used microcrystalline cellulose and lactose as the main components. Thermally controlled spheronisation at elevated temperature produced pellets within a narrow size distribution. It was found that the …

Planar visual fusion scintigraphy
… this problem is by registering and fusing a scintigraphic image with a digital visual image. Fusing planar scintigraphic images with visual photographic images to supply an anatomic correlate to regions of radiopharmaceutical accumulation has been explored in this study. The digital visual …

Monte Carlo Simulations of Novel Scintillator Detectors and Dosimetry Calculations
… a system able to acquire both echographic and scintigraphic images to let the medical operator obtain the complete anatomic and functional information for tumor diagnosis. The scintigraphic part of the detector is simulated by GEANT4 and first attempts to reconstruct tomographic images have …

Aspects of paediatric gastro oesophageal scintigraphy
… Tc-99m compounds. Other contributions are a scintigraphic means to allow recognition of the importance of oesophageal dysmotility in paediatrics, especially in the absence of GOR and its relevance to the efficacy of surgery in cases of apparent GOR. Also, this gastro oesophageal scintigraphic …

Evaluation of Thyroid to Background Ratios in Hyperthyroid Cats
… severity of the disease. Previously established scintigraphic quantitative methods, thyroid to salivary ratio (T:S ratio) and % dose uptake, are the most widely recognized measurements. Recently, the thyroid to background ratio (T:B ratio) has been proposed as an alternate method to assess …

Investigation of bone response to implant materials by electron microscopy and computer simulation
(cont.) implementation of this scintigraphic method for quantitative studies of osteoblast-mediated mineralization in vitro. A 2-D truss finite element model is used to study the remodeling of trabecular bone. Using strain energy density (SED) as the optimization object and the trabecular width as …

Design, Synthesis and Biological Properties of Estrogen Receptor Binding Breast Tumor Localizing Agents
… evaluated (dosimetry, pharmacology) for use as a scintigraphic agent in humans. This compound was used to obtain an image of a primary human breast tumor that was shown to contain high levels of estrogen receptor upon removal. These results are the first example of scintigraphic imaging of …

The role of Technetium-99m Sestamibi scintimammography to evaluate palpable breast lesions : a comparison with mammography and histological results
… a separate Additional Study, with the same scintigraphic method, was conducted on patients with clinical breast lumps with indeterminate mammographic lesions. Special emphasis was placed on lesion by lesion comparison of each breast lesion detected by clinical examination or …

Quantitative Pertechnetate Thyroid Scintigraphy and the Ultrasonographic Appearance of the Thyroid Gland in Clinically Normal Horses
The purpose of this study was to report the scintigraphic and sonographic appearance of the thyroid gland in clinically normal horses so these modalities could be used to assess the thyroid gland in this species. Horses were divided into two age groups. Group A consisted of 8 horses between 3 and …

The differentiation of extrahepatic biliary atresia from the neonatal hepatitis syndrome
… in infants with obstructive jaundice. The scintigraphic demonstration of excretion into the gut excludes extrahepatic obstruction, however, absence of excretion may be due to EHBA, severe cholestasis with patent extrahepatic bile ducts or poor uptake of the agent, and is therefore not …
