Interpretation of images obtained. How good is interobserver reproducibility in reporting on DMSA scintigraphy? Poor concordance as well as good concordance has been observed. Renal 99m Tc-dimercaptosuccinic acid (DMSA) scintigraphy is currently the method of choice for detecting renal cortical abnormalities and scarring in children, notably in relation to urinary tract infections [1, 2]. 99m Tc-DMSA renal scintigraphy revealed parenchymal abnormalities in 24 refluxing renal units (41%) in 22 patients (65%), of whom 19 (86%) were male and 15 (68%) had bilateral reflux. We noted differential uptake less than 40% with and without cortical defects in 10 and 7 refluxing units, respectively, and cortical defects only in 7.

DMSA scintigraphy is employed primarily in the pediatric population to support acute pyelonephritis and hematogenic nephritis diagnoses and in the management of their late sequelae.13Pathologic entities such edema, ischemia, and infarcts also can be detected with high sensitivity. 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. 99m Tc-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.

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 Tc-DMSA renal scintigraphy is widely accepted as the most sensitive method for detecting parenchymal lesions and diagnosing acute pyelonephritis. Qualitative and quantitative evaluation standards were elaborated to improve the interpretation of DMSA scintigraphy. The normal DMSA distribution pattern, the average background uptake, and scintigraphic kidney length according to age were assessed in 95 presumably healthy kidneys.

The frequency of parenchymal lesions during acute DMSA in children after a first episode of febrile UTI in our study was 47.36%.

DMSA, or dimercaptosuccinic acid, is a radioactive compound (radiopharmaceutical) that when injected into a vein allows images or pictures to be taken of the kidneys.

Genom att tillsätta en liten mängd radioaktivt teknetium (99mTc) kan man registrera DMSA i njurarna med en gammakamera - scintigrafi, och presentera resultatet i form av bilder. Bilderna avspeglar njurarnas funktion. DMSA kidney scans are predominately done on young children but can also be for adults.

Kidney – DMSA Scintigraphy The DMSA program is used to display radioactive tracer distribution in the kidneys and calculate L/R relation. This program is applicable function at 99mTc-DMSA scintigraphy ABSTRACT Today a kidney DMSA-scintigraphy is performed when the issue is urinary tract infection and pyelonephritis in children, due to the sensitivity and availability of the test. The European Association for Nuclear Medicine recommends background correcting images in renal scintigraphy with DMSA.

Qualitative and quantitative evaluation standards were elaborated to improve the interpretation of DMSA scintigraphy. The normal DMSA distribution pattern, the average background uptake, and scintigraphic kidney length according to age were assessed in 95 presumably healthy kidneys. 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 Scintigraphy with Tc-99m dimercaptosuccinic acid (DMSA) is considered a reference method for assessment of parenchymal lesions and estimation of differential kidney function.
