This study assessed zooplankton density and Chl-a amount to understand their spatial seasonal variation in Lake Malombe. Samples were collected for analysis during the hot, dry season (HDS) cool, dry, windy (CDWS). The identified Tropodiaptomus cunningtoni (TC), Mesocyclops aequatorialis (MAA), Thermocyclops neglectus (TN), Bosmina longirostris (BL), Diaphanosoma spp. (DS), Nauplii. These group...

deep vein thrombosis (dvt) is an important life threatening condition that is difficult to diagnose, particularly in the early stages. looking for dvt in lower limb can be considered ancillary in suspected cases of pulmonary embolism (pe) indirectly highlighting a cause and effect relationship of a single disease (i.e cause being dvt and effect is the assault on the lung vasculature). prompt an...

A 56-yr-old man, two months after an operation for an acoustic neurinoma, gradually developed dyspnea. Massive pulmonary embolism (MPE), with a significant right-to-left (R-L) shunt, was seen in a perfusion scan of the lungs with Tc-99m MAA. Radioactivity was noted in the thyroid, spleen, kidneys and brain. A cardiac ultrasound study did not reveal intracardiac shunting. A few days later, when ...

c 5 XTRAPULMONARY accumulation of Tc macroaggregated albumin (MAA) is rarely een on perfusion lung scan, and has been reported n less than 4% of a study population of nearly 380 atients.1 It occurs when the agent bypasses the ungs due to a right-to-left (R-L) cardiac or pulonary shunt, when it is shunted to the portal vein efore reaching the right atrium and ventricle of he heart, and when the ...

PURPOSE: In this study, using quantitive VOI analysis, the percentage Tc-MAA uptake and SUVmax and mean values of liver metastases obtained prior to SIRT by means of Theraspheres were related to treatment response. METHODS: Pretreatment FDG PET/CT scans and Tc-MAA SPECT/CT scans as well as post-treatment FDG PET/CT scans were coregistered and spherical VOI’s drawn around FDG positive liver lesi...

Introduction: Nowadays, nuclear medicine (NM) imaging indications in medical practice is raising. A practical step to get closer to the optimization rule is collecting data about patients’ exposure and definition of guidance levels. The aim of this study was definition of local reference level in Isfahan city. Materials and Methods: Questionnaires were given...

The aim of this study was to evaluate the incidence of deep vein thrombosis (DVT) in patients with suspected pulmonary embolism (PE) and the relation between PE and the site of DVT by using technetium-99m-macroaggregated human serum albumin ((99m)Tc-MAA) radionuclide venography (RNV). Technetium-99m-MAA RNV was performed simultaneously with lung perfusion scintigraphy in 123 patients with s...

Background/Aim: Albuminuria is recognized as an early marker of diabetic nephropathy, but glomerular hyperfiltration appears prior to its development. The aim of this study was to assess relationship between the rates of urinary albumin excretion and glomerular filtration in different diabetic kidney disease stages of type 1 diabetes mellitus. Methods: According to urinary albumin excretion rat...

OBJECTIVE Balloon pulmonary angioplasty (BPA) is used for inoperable chronic thromboembolic pulmonary hypertension (CTEPH), but its effect cannot be evaluated noninvasively. We devised a noninvasive quantitative index of response to BPA using three-dimensional fractal analysis (3D-FA) of technetium-99m-macroaggregated albumin (Tc-MAA) single-photon emission computed tomography (SPECT). PATIEN...

El hiperparatiroidismo primario (HPTP) es la principal causa de hipercalcemia en pacientes no hospitalizados, estando causado el 85-90% los casos por un adenoma solitario. La cirugía radioguiada paratiroides (CRGP), como técnica GOSTT (Guided intraOperative Scintigraphic Tumor Targeting), utiliza SPECT-TC con 99mTc-MIBI elección. PET-TC 18F-Colina (18FCH) puede emplearse negativo, obteniéndose ...
