Because DMSA scintigraphy is invasive and expensive, our study also presents data on the use of PCT for the selection of cases, in which DMSA could be omitted. The frequency of parenchymal lesions during acute DMSA in children after a first episode of febrile UTI in our study was 47.36%.

mTc-DMSA scintigraphy is clearer and better defined than that obtained by IVP. Case 2 In this 42-year-old female (Fig. 3), a unilateral fused kidney is well demonstrated by 99 mTc-DMSA renal scintigraphy. 99 mTc-DMSA renal uptake was 29%, the BUN 18 mg/l00 mL, and serum creatinine was 1.4 mg/lOO mL. The IVP failed

DMSA scintigraphy was performed at a median of 10 days after the start of treatment and was abnormal in 73 children (42%), equivocal in 29 (16%) and normal in 73 (42%). Reflux was seen in 27% of all children and in 38% of the renal units that were abnormal at DMSA scintigraphy. DMSA scintigraphy is indicated in children for evaluation and/or detection of acute pyelonephritis, renal scars, small kidneys, duplicated collecting systems, renal masses and systemic hypertension . 99m Tc DMSA is a renal cortical scanning agent that localizes in the proximal tubules.

You can usually leave the hospital or nuclear medicine facility after the injection and return later. DMSA scintigraphy is indicated in children for evaluation and/or detection of acute pyelonephritis, renal scars, small kidneys, duplicated collecting systems, renal masses and systemic hypertension . 99m Tc DMSA is a renal cortical scanning agent that localizes in the proximal tubules. Renal Cortical Scintigraphy DMSA Dimercaptosuccinic acid Pseudomasses (fetal lobulation, hypertrophic column of Bertin) To locate the functioning renal tissue Differentiate renal cortex from the soft tissue masses in and adjacent to kidneys, to find scars or non functioning areas of renal parenchyma and to establish the functional contribution of an abnormal kidney. Renal Cortical Scintigraphy (DMSA scan) Clinical Guidelines 1. Purpose This guideline must be read in conjunction with the BNMS Generic Guidelines. The purpose of this guideline is to assist specialists in Nuclear Medicine and Radionuclide Radiology in recommending, performing, interpreting and reporting Single-photon emission computed tomography (SPECT) DMSA scintigraphy is superior to planar imaging for detection of renal cortical damage.

The purpose of this guideline is to assist specialists in Nuclear Medicine and Radionuclide Radiology in recommending, performing, interpreting and reporting Scintigraphy with Tc-99m dimercaptosuccinic acid (DMSA) is considered a reference method for assessment of parenchymal lesions and estimation of differential kidney function. The aim of study was to evaluate Tc-99m mer-captoacetyltriglycine (MAG3) dynamic renal scintigraphy for the same purpose. 188 patients, submitted to both stud- Renal Cortical Scintigraphy DMSA Dimercaptosuccinic acid Pseudomasses (fetal lobulation, hypertrophic column of Bertin) To locate the functioning renal tissue Differentiate renal cortex from the soft tissue masses in and adjacent to kidneys, to find scars or non functioning areas of renal parenchyma and to establish the functional contribution of an abnormal kidney.

Low differential function (≤ 3% and ≤ 2%, respectively) indicates irreversible lesions, favoring heminephrectomy. Higher differential function indicates greater remaining biological potential of the parenchyma, favoring reconstruction of However, DMSA scintigraphy has the disadvantages of ionizing radiation exposure, invasiveness, and relatively high cost, rendering it unappealing to children and parents . The recent development of power Doppler ultrasonography (PDU) shows encouraging results in diagnosing APN, with a … Follow-up of acute pyelonephritis in children by Tc-99m DMSA scintigraphy - Quantitative and qualitative assessment. / Wallin, Lena; Helin, Ingemar; Bajc, Marika.. In: Clinical Nuclear Medicine, Vol. 26, No. 5, 2001, p. 423-432. Research output: Contribution to journal › Article The ectopic renal function estimation based on a manual region of interest (ROI) extraction could be considered as time consuming.

If the DMSA in acute setting is normal, there is no risk of renal scarring. A sharp segmental defect on DMSA imaging may be referred to renal infarction; on the contrary, simple cysts generally are surrounded by a thin rim of parenchyma or appear more rounded on parenchymal edge than 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy is currently the method of choice for assessing renal scarring in children, but it is not established whether conducting the scan as a single photon emission tomography combined with low-dose CT (SPECT/ldCT) scan provides additional diagnostic benefits when compared to conventional planar scintigraphy. Because DMSA scintigraphy is invasive and expensive, our study also presents data on the use of PCT for the selection of cases, in which DMSA could be omitted.

DMSA scintigraphy associated with other diagnostic methods can improve the sensitivity and specificity to establish renal damage stage. During the follow-up the acute lesions disappeared or improved in all cases and the chronic lesions have not been modificated.

On the basis of previous experimental studies, DMSA scintigraphy was used as the standard of reference for the diagnosis of acute pyelonephritis. The DMSA scans showed changes consistent with acute pyelonephritis in 63% (57/91) of the patients. DMSA kidney scans are predominately done on young children but can also be for adults. Children would be referred for this kind of scan following a urine inf Interobserver Variability in Interpretation of Planar and SPECT Tc-99m-DMSA Renal Scintigraphy in Children.
