A 26-y-old patient with end-stage renal disease and recent dual transplantation of cadaveric kidneys en bloc presented with increasing abdominal pain and a rising level of serum creatinine. An anterior-view (99m)Tc-mercaptoacetyltriglycine renogram demonstrated the typical overlap of the lower pole of the superior kidney and the upper pole of the inferior kidney. The renogram was consistent wit...

Renal scintigraphy is performed frequently in infants and children. Renal cortical scintigraphy using 99mTc dimercaptosuccinic acid is predominantly performed to assess the renal sequelae of urinary tract infection. It is most commonly performed for the evaluation of chronic renal scars, although it is also undertaken in the assessment of acute pyelonephritis. Diuresis renography using 99mTc me...

TO THE EDITOR: We read with much interest the paper published by Garcia et al. (1) on an expert system for the diagnosis of renal obstruction using 99mTc-mercaptoacetytriglycine (MAG3) renography. Providing that an acceptable gold standard exists, a validated expert system may help an inexperienced observer in daily clinical work. Unfortunately, the diagnosis of renal obstruction is a matter of...
