Simplified Method for Renal Uptake Rate Measurement with 99mTc-Dimercaptosuccinic Acid Using Graphical Analysis.

99mTc dimercaptosuccinic acid (DMSA) scan in patients with established radiological renal scarring.

The findings on 99mTc dimercaptosuccinic acid (DMSA) scans were examined in 54 patients aged 3 to 33 years in whom renal scarring had been diagnosed radiologically in childhood after urinary tract infection. There was no recent history of infection. Vesicoureteric reflux had been present in 48 patients and had stopped in 23 at the time of the DMSA scan. In six of the 72 radiologically scarred k...

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

Acute phase 99mTc-dimercaptosuccinic acid scan in infants with first episode of febrile urinary tract infection.

BACKGROUND 99mTc-dimercaptosuccinic acid (DMSA) scan is the golden standard for the diagnosis of acute pyelonephritis and renal scaring. We investigated the use of acute phase DMSA scan in infants presented promptly to the hospital because of the first episode of their febrile urinary tract infection (UTI). METHODS Ninety-eight infants with microbiologically confirmed first episode of febrile...

Estimation of absolute renal uptake with technetium-99m dimercaptosuccinic acid: direct comparison with the radioactivity of nephrectomy specimens.

CONTEXT AND OBJECTIVE Studies using radionuclides are the most appropriate method for estimating renal function. Dimercaptosuccinic acid chelate labeled with technetium-99m (99mTc-DMSA) is the radiopharmaceutical of choice for high-resolution imaging of the renal cortex and estimation of the functional renal mass. The aim of this study was to evaluate a simplified method for determining the abs...

Graphical analysis of 99mTc thyroid scintigraphy.

A new non-invasive simple method for quantitative evaluation of thyroid was presented using graphical analysis of the transfer process of technetium-99m pertechnetate (99mTc) from the blood to thyroid. Thirty subjects were studied. After a bolus injection of 111 MBq of 99mTc, the data were recorded on a 128 x 128 matrix as 60 frames of 1.5-second duration. ROIs were placed over the aortic arch ...
