High fluid intake has been universally recommended for kidney stone prophylaxis. We evaluated 24-h urine osmolality regarded as the best biomarker of optimal hydration and upper metastable limit after water evaporation from sample to onset spontaneous crystallization its usefulness a new risk index that would describe an individual lithogenic potential. collected 257 pediatric patients with stones 270 controls. After volume assessment, samples were subjected reduction in vacuum rotavapor...
Objective The objective of this study is to investigate the feasibility and potential advantages 99m Tc-DTPA dynamic single photon emission computed tomography/computed tomography (SPECT/CT) renogram in adults. Methods Fifty-five patients aged 19–80 years (mean 56.3) were enrolled. imaging protocol included: day 1: planar renogram, followed by Tc-DMSA scan. Day 3: attenuation-corrected SPECT [DSPECT(AC)] Cr-51 ethylenediamine tetraacetic acid (EDTA) glomerular filtration rate (GFR)...
Abstract Aim This study determined the specific reference values for urinary phosphorus excretion in healthy children and adolescents aged 2–18 years evaluated whether they changed with age during growth were gender dependent. Methods We enrolled 3913 to this study. The population was divided into groups, analysis performed one‐year periods, separately boys girls. Urinary analysed using four categories: P1 mmol/24 hour units, P2 mmol/kg/24 hours, P3 mmol/1.73 m 2 /24 hours P4 mmol/mmol...
<title>Abstract</title> Objective To investigate the feasibility, quantitative parameters and potential advantages of dynamic SPECT/CT renogram with <sup>99m</sup>Tc-DTPA in adults. Methods Fifty-five (55) patients aged 19–80 y.o. most them obstructive uropathy were enrolled. The imaging protocol included: Day 1: a) Conventional planar renogram, followed by b) <sup>99m</sup>Tc-DMSA injection static 3 hrs post injection. 3: c) Dynamic 333–444 MBq <sup>99m</sup>Tc-DTPA. This included an...
Although brown adipose tissue (BAT) is considered to play a protective role against obesity and type 2 diabetes, the mechanisms of its activation associations with clinical parameters are not well described. Male adults underwent h cold exposure (CE) activate BAT and, based on results PET/MRI performed after CE, were divided into BAT(+) BAT(-) groups. During CE procedure, blood samples collected alterations in plasma metabolome both groups investigated using LC-MS. Additionally, between...
Commonly used technologies for visual pattern stimulation cannot operate in a magnetic resonance imaging room because they can interfere with the operation of scanner and are vulnerable to its electromagnetic fields. The aim this single-center prospective observational study was introduce novel, structurally uncomplicated, easy-to-maintain, patterned edge-illuminated display (PEID) device pattern-reversal stimulation, compare it commonly cathode ray tube screen, verify equivalence...
Abstract Diffusion-weighted magnetic resonance imaging of the human optic nerve and tract is technically difficult because its small size, inherent strong signal generated by surrounding fat cerebrospinal fluid, due to eddy current-induced distortions subject movement artifacts. In addition, effects bone channel through which passes, proximity blood vessels, muscles tendons are generally unknown. Furthermore, limited technical capabilities scanners minimization acquisition times result in...
