All patients received both a gallium scan and a DMSA scan. DMSA scintigraphy was per- formed 3–4 h after an injection of 740 MBq (20 mCi) of. Tc-99m DMSA.

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.

Although 99m Tc-dimercaptosuccinic acid (DMSA) scintigraphy is widely considered the method of choice for detecting renal cortical scarring in children, notably after pyelonephritis [1,2], currently, conventional planar scintigraphy rather than single photon emission tomography combined with low-dose CT (SPECT/ldCT) is recommended . 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.

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.

Mark; Abstract A total of 282 renal scintigrams with Tc-99m DMSA in 238 children ranging in age from 10 days to 13 years performed during a 3-year period were reviewed. 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.

A retrospective analysis detected renal damage on DMSA scintigraphy in 5 of 41 children with SD who were followed according to a proactive national program

In press. VI Follow up of acute pyelonephritis in children by DMSA scintigraphy. Single-photon emission computed tomography (SPECT) DMSA scintigraphy is superior to planar imaging for detection of renal cortical damage. 30,31 The sensitivity of DMSA scintigraphy in experimentally induced acute pyelonephritis in a pig model was reported to be 92% compared with histologic findings. 32 By use of standardized criteria for its interpretation, high levels of intraobserver and Tc-99m DMSA Scintigraphy Commercially available DMSA kit was prepared accord-ing to manufacturers’ recommendations using 370–555 MBq (10–15 mCi) Tc-99m pertechnetate.

Radioactive technetium-99m is combined with DMSA and injected into a patient, followed by imaging with a gamma camera after 2-3 hours. 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. The DMSA renal scan is a nuclear medicine test that gives doctors detailed pictures of the kidneys. DMSA (dimercapto succinic acid) is a short-lived radioisotope that goes directly to the kidneys once inside the body and only stays radioactive for a few hours.

This results in higher concentration and hence much higher resolution with pinhole SPECT. Also, it allows better assessment of differential renal function. Renal Scintigraphy Carlos Cunha Pereira Neto Dominique Delbeke Renal scintigraphy has been used in clinical nephrourology since the early 1960s. It provides functional and anatomic information, both closely related. Structural information, however, is limited.
