urinary tract infection (uti) may lead to irreversible changes in renal parenchyma. early diagnosis using scintigraphy with technetium-99 m -labeled dimercaptosuccinic acid (dmsa) scan and early treatment may decrease or prevent development of renal parenchymal lesions. the aim of this study was to assess the occurrence of renal parenchymal lesion in children admitted with a first-time symptoma...

A 2.5-year-old boy with a history of the previous incidental finding of an ectopic kidney in ultrasonography was referred to our nuclear medicine center for 99mTc-DMSA renal scintigraphy. The scan showed an unusual type of ectopic fused kidneys on the right side of the lower abdomen. In this anomaly, kidneys were fused completely across the medial portion of both upper and lower pole...

introduction due to limitation of colonoscopy in assessing the entire bowel and patients’ intolerance in inflammatory bowel disease (ibd), in the current study, we aimed to prospectively compare the accuracy of 99m tc(v)-dimercaptosuccinic acid (dmsa) and fecal calprotectin with ileocolonoscopy as new methods for localizing inflammations. methods current prospective study conducted between 2012...

OBJECTIVE In this prospective study we investigated the role of plasma levels of soluble urokinase plasminogen activator receptor (suPAR) in children with urinary tract infection. MATERIAL AND METHODS We measured the levels of plasma suPAR during admission in 42 children with suspected acute pyelonephritis and compared the results to acute DMSA scintigraphy. RESULTS The mean level of plasma...

BACKGROUND Symptoms and signs of acute tubulointerstitial nephritis (ATIN) are nonspecific; therefore, renal biopsy is often necessary to clarify the diagnosis. The aim of this study was to evaluate the use of 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy in the diagnosis and follow-up of ATIN. METHODS We retrospectively reviewed the charts of five patients (nine renal units) with a media...

BACKGROUND Differential renal function (DRF) measurements are routinely corrected for background, which mainly affects the reproducibility and accuracy of the measurement. The present study was conducted to identify the most appropriate background ROI and optimal time interval in the calculation of DRF for EC renography. MATERIALS AND METHODS Nineteen patients were studied. For determination ...

This prospective study was done to assess the frequency of acute pyelonephritis (APN) in febrile children with positive urine culture as documented by Tc99m DMSA scintigraphy (DMSA) and the frequency of vesicoureteric reflux (VUR) in these children. Secondly, to determine the frequency of APN, in febrile children with supportive evidence for UTI but with negative urine culture, as documented by...

BACKGROUND AND PURPOSE To evaluate clinical variables for diagnosing childhood acute pyelonephritis (APN) when technetium-99m dimercaptosuccinic acid (DMSA) scintigraphy is not available. METHODS We retrospectively reviewed the records of 590 children with febrile UTI seen from January 1999 to February 2004. On the basis of DMSA scintigraphy performed within 7 days after admission, they were ...

UNLABELLED Capabilities of color and power Doppler sonography (DS) were prospectively evaluated for diagnosis of acute pyelonephritis and for prediction of scarring by comparison with 99mTc-dimercaptosuccinic acid scintigraphy (DMSA). METHODS Fifty-seven children (mean age, 5 +/- 3 y) with acute pyelonephritis were investigated by biologic testing, DS (DS 1), and DMSA (DMSA 1). Patients who w...

The purpose of this guideline is to offer to the nuclear medicine team a framework that could prove helpful in daily practice. This guideline contains information related to the acquisition, processing, interpretation and indications for 99m Tc-DMSA scintigraphy in children. This guideline summarizes the views of the Paediatric Committee of the European Association of Nuclear Medicine. It shoul...
