Limitations of 99mTc-DMSA scan in diagnosing acute pyelonephritis in children

Diagnosing Acute Pyelonephritis with CT, 99mTc-DMSA SPECT, and Doppler Ultrasound: A Comparative Study

PURPOSE With growing interest in early imaging, the aim of our study was to define the most practical modality for routine clinical use for the diagnosis of acute pyelonephritis (APN). We compared the sensitivity of enhanced computerized tomography (CT), dimercaptosuccinic acid (DMSA) scintigraphy, and Doppler ultrasonography (DUS) by using clinical findings as the standard of reference.

Doppler ultrasonography in children with acute pyelonephritis in diagnosis of renal scar compared to DMSA scintigraphy

Background: Urinary tract infection (UTI) is one of the most important pediatric health problems, which is occasionally associated with irreversible renal damage. Dimercapto-succinic acid (DMSA) scan is a diagnostic standard for the renal scar. Doppler ultrasonography (D.S) has been considered as a less invasive method. The purpose of this study was to determine the sensitivity and specificity ...

Results of a five-year study of 99mTc DMSA renal scintigraphy in children and adolescents following acute pyelonephritis.

BACKGROUND Renal scintigraphy, generally using 99mTc-DMSA, is the accepted reference standard for detection of renal cortical changes. The timing of the test, i.e., whether an acute 99mTc-DMSA scan, a follow-up only or both scans should be performed, however, remains open to discussion. In our study, a six-month follow- up DMSA scan was performed in all the children diagnosed with a first attac...

99mTC dimercaptosuccinic acid (DMSA) scan in urinary tract infection.

تعیین میزان گرفتاری پارانشیم کلیه با استفاده از سنتی گرافی قشر کلیه (اسکن DMSA) در کودکان مبتلا به پیلونفریت حاد مرکز طبی کودکان، 80-1379

Background: Urinary tract infection is a common bacterial infection in children and may lead to irreversible renal damage. TC 99-m Dimercaptosuccinic acid renal scintigraphy is the most sensitive method for diagnosing acute pyelonephritis. We designed a study to evaluate the ability of DMSA scan and ultrasonography to detect renal paranchymal lesion. Materials and Methods: 62 children 1 month t...
