Technetium-99m sulphur colloid (99mTc-SC) scintigraphy is a commonly used method in the assessment of peritoneopleuric leak in cases of liver insufficiency [1-4]. A 40 years old patient with alcoholic cirrhosis liver insufficiency, ascitis and hepatic encephalopathy was severely dyspnoic due to large right sided pleural effusion. A 99mTc-SC peritoneo-pleuric scintigraphy was performed. A 1.5 in...

Oceanic mesoscale eddies (with a diameter of 50–100 km) are known to be associated with significant vertical tracer fluxes in the upper few hundred meters. In particular, they are important for the biogeochemical system, accounting for 20–30% of the vertical nutrient transport. However, estimates of the global tracer fluxes neglect the role played by thin elongated filaments (with a width of 5–...

PURPOSE The purpose of this study was to localize the cell bodies of palisade endings that are associated with the myotendinous junctions of the extraocular muscles. METHODS Rhesus monkeys received tract-tracer injections (tetramethylrhodamine dextran [TMR-DA] or choleratoxin subunit B [CTB]) into the oculomotor and trochlear nuclei, which contain the motoneurons of extraocular muscles. All e...

PURPOSE To evaluate (99m)Tc-mercaptoacetyltriglycine diuretic renograms for diagnosing stomal obstruction in tubeless cutaneous ureterostomy. MATERIALS AND METHODS Cutaneous ureterostomy was performed in 29 patients (56 renal units) with a minimum follow-up period of 12 months. Stomal obstruction was evaluated with (99m)Tc-mercaptoacetyltriglycine diuretic renography 3 months after surgery. R...

Tracers provide users with useful information about program executions. In this article, we propose a tracer driver . From a single tracer, it provides a powerful front-end enabling multiple dynamic analysis tools to be easily implemented, while limiting the overhead of the trace generation. The relevant execution events are speci ed by exible event patterns and a large variety of trace data ca...

This work is concerned with conditional averaging methods which can be used for modeling of transport in porous media with volume reactions in the fluid phase and surface reactions at the fluid/solid interface. The model under consideration takes into account convection, diffusion within the pores and on larger scales, and homogeneous and heterogeneous reactions. Near the interface with fractal...

Fluid mixing in active suspensions of microorganisms is important to ecological phenomena and presents a fascinating stochastic process. We investigate the mixing produced by swimming unicellular algal cells (Chlamydomonas) in quasi-two-dimensional liquid films by simultaneously tracking the motion of the cells and that of microscopic passive tracer particles advected by the fluid. The reduced ...

objective(s): the study objective was to assess the diagnostic performance of positron emission tomography (pet) for gliomas using the novel tracer 18f-fluciclovine (anti-[18f]facbc) and to evaluate the safety of this tracer in patients with clinically suspected gliomas.methods: anti-[18f]facbc was administered to 40 patients with clinically suspected high- or low-grade gliomas, followed by pet...

introduction: this study was done to determine the site of obstruction in lacrimal drainage system in asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. methods:dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99mtc) in 34 patients suffering from unilateral or bil...

[1] Cross-well electrical resistivity tomography (ERT) was used to monitor the migration of a saline tracer in a two-well pumping-injection experiment conducted at the Massachusetts Military Reservation in Cape Cod,Massachusetts. After injecting 2200mg/L of sodium chloride for 9 hours, ERT data sets were collected from four wells every 6 hours for 20 days. More than 180,000 resistance measureme...
