The multicystic dysplastic pattern in a half of a horseshoe kidney is a very uncommon presentation. We present a 6-month-old male infant with a history of antenatally unilateral cystic abnormality in the right kidney which was reevaluated after birth by ultrasonography (US) and 99m Tc-DMSA scintigraphy. The US showed a horseshoe kidney with the multicystic dysplastic area on the right side

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. DMSA scintigraphy is normal in the absence of anatomical lesions and only small lesions are missed by DMSA scintigraphy. Interpretation of images obtained.

Dmsa scintigraphy

The renal DMSA scintigraphy of the 52 duplicated kidneys revealed insignificant parenchymal damage in 19 kidneys. Moderate parenchymal damage existed in 10 kidneys. In the remaining 23 kidneys, severely deteriorated function of the upper moiety was found in 15 cases and of the lower pole in 9 cases, as both moieties were affected in one kidney. Technetium-99m ( 99m Tc)–labeled pentavalent dimercaptosuccinic acid ( [ 99m Tc]- (V)DMSA) has been used for renal scintigraphy (see below for references) as well as detection and postoperative evaluation of medullary carcinomas of the thyroid (MCT). [ 99m Tc]- (V)DMSA has been shown to accumulate in breast tumors, head and neck cancers, To demonstrate renal involvement in acute urinary tract infection, DMSA scintigraphy should be performed within days after the start of treatment. It is noteworthy that reflux was seen in less than half of renal units with abnormal DMSA scintigraphy. DMSA is an ideal agent for assessment of the renal cortex as it binds to the sulfhydryl groups in proximal tubules at the renal cortex with longer retention than other agents.

DMSA (dimercaptosuccinic acid) är ett ofarligt ämne, som tas upp i njurarna sedan det sprutats i en blodåder. 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.

Interpretation of images obtained. How good is interobserver reproducibility in reporting on DMSA scintigraphy?

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.

Objective. To determine the effects of percutaneous nephrolithotomy on renal functions by using DMSA scintigraphy while considering access counts. Material and Methods.

Radioisotope renography is a form of medical imaging of the kidneys that uses radiolabelling.A renogram, which may also be known as a MAG3 scan, allows a nuclear medicine physician or a radiologist to visualize the kidneys and learn more about how they are functioning. DMSA renal scintigraphy provides a useful tool for the prediction of irreversible lesions in the upper pole. 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 RESULTS: 99m Tc (V) DMSA scintigraphy had a 92% (33 of 36) sensitivity and an 86% (24 of 28) specificity in the detection of active IBD. A significant correlation between disease activity indices and scintigraphy score was demonstrated.

Conclusion: 99m-Tc DMSA scintigraphy is the gold standard for early identification and Keywords- DMSA Scan, USG, Urinary Tract Infection, Children

How good is interobserver reproducibility in reporting on DMSA scintigraphy? Poor concordance as well as good concordance has been observed. Plain B-mode sonography, CT with contrast medium, and (99m)Tc-DMSA scintigraphy of the kidneys were performed in all patients. Both CT and (99m)Tc-DMSA scintigraphy were performed within 72 h after admission. RESULTS: Twelve patients with clinical and biological signs of urinary tract infection had no CT or (99m)Tc-DMSA scintigraphy abnormalities. IV Kidney size estimation by DMSA scintigraphy in piglets.
