The main tool of radionuclide techniques applied to paediatric uro-nephrology is the quantitation of function, which is an information not easily obtained by other diagnostic modalities. The radiation burden is low. Drug sedation is only rarely needed, whatever the age of the patient. Accurate determination of glomerular filtration rate can be obtained by means of an intravenous injection of Cr...

INTRODUCTION The aim of this study was to evaluate the accuracy of Technetium Tc 99m dimercaptosuccinic acid (99mTc-DMSA) renal scintigraphy in the diagnosis of urinary tract infection (UTI) in children with suspected infection but with a negative urine culture. MATERIALS AND METHODS The records of all children with suspected or definite diagnosis of UTI presented during a 2-year period were ...

BACKGROUND Renal osteodystrophy is a metabolic bone disease and a common complication of end-stage chronic renal failure and maintenance dialysis treatment. In this study, we examined the correlation between quantifying bone scintigraphy and serum biochemical markers in hemodialysis patients. METHODS Bone scintigraphy with technetium-99m-hydroxy-methylene-diphosphonate (99mTc-HMDP) was perfor...

We report a 50-year-old woman diagnosed with Sneddon's syndrome and examined by CBF scintigraphy several times for follow-up of the disease. There were no significant changes in her CBF scintigraphic findings or neurological status during the 6-year follow-up period. Sneddon's syndrome is a slowly progressive disorder in which livedo reticularis precedes cerebrovascular accidents. Because small...

Renal scintigraphic methods, which are physiologic and minimally invasive, have played important role in the management of various renal diseases in children, providing sensitive tool for early detection of disease even before structural changes become prominent and giving valuable functional and anatomical information to aid medical decision makings in the treatment and follow-up of patients. ...

Introduction: The optimal imaging time of a radionuclide scintigraphy is the time at which the organ of interest has the maximum uptake of the injected radionuclide. This study was performed to investigate the maximum uptake time of 99mTc-DMSA in rat renal scan. Methods: Renal scintigraphy was performed with 3 mCi of 99mTc-DMSA. Planar images were acquired every 20 minutes for 8 hours post-inje...

Abstract Background Even if prevalent among patients with severe aortic stenosis (AS), the clinical suspicion for transthyretin cardiac amyloidosis (ATTR-CA) remains difficult in this subset. Methods Consecutive AS undergoing transcatheter valve replacement (TAVR) evaluation at a single center were prospectively included. Those suspected ATTR-CA based on assessment underwent 99mTc-DPD scintigra...

OBJECTIVE To investigate the influence of bladder fullness on the diagnosis of urinary tract obstruction during dynamic renal scintigraphy with a diuretic stimulator. MATERIALS AND METHODS We studied 82 kidneys in 82 patients submitted to dynamic renal scintigraphy with a diuretic stimulator. We compared the proportional elimination of the radiopharmaceutical 99mTc-DTPA from the kidneys befor...
