The Sandaozhuang super-large W-Mo deposit is located in the southern margin of North China Craton, within well-known East Qinling Mo mineralization belt, and one typical skarn-type deposits China. Based on EMPA LA-ICP-MS analyses, major trace elements were presented, mineral chemistry magnetite at various stages was discussed. Combining field observations, petrography, geochemical characteristi...

Recent studies have suggested that technetium-99m (19mTc) MAG3 can be substituted for iodine-131 ( 131 I) OIH, with better image quality and lower radiation dose. This study compares the two radiopharmaceuticals for effective renal plasma flow (ERPF) results using only the camera method. Twenty patients with varying degrees of renal impairment were studied. In 13 of these patients, direct compa...

UNLABELLED We investigated the value of supranormal function and renogram patterns on (99m)Tc-mercaptoacetyltriglycine ((99m)Tc-MAG3) scintigraphy in relation to the extent of hydronephrosis for predicting ureteropelvic junction (UPJ) obstruction in the newborn. METHODS We studied 48 patients with prenatally diagnosed unilateral hydronephrosis that was confirmed on postnatal ultrasonography. ...

UNLABELLED The significance of delayed tissue tracer transit (TTT) of (99m)Tc-mercaptoacetyltriglycine ((99m)Tc-MAG3) has not been systematically evaluated in hydronephrosis. We sought to demonstrate that delayed TTT accompanies both functional decline and histomorphologic restructuring. METHODS Twenty 2- to 3-mo-old piglets with surgically induced partial unilateral ureteral stenosis were ex...

The purpose of this study was to evaluate renographic parameters obtained from healthy renal units (RUs) in newborns and infants with unilateral kidney condition. Thirty three children including twenty newborns, referred to Technetium-99m mercaptoacetyltriglycine (Tc-99m MAG3) diuretic scintigraphy due to unilateral kidney condition entered the study. Only contralateral, healthy RUs were analyz...

BACKGROUND Radiation-induced nephropathy is still dose limiting in radionuclide therapy of neuroendocrine tumors. We investigated the nephroprotective potential of the angiotensine converting enzyme inhibiting drug enalpril after [177Lu]-DOTATATE therapy in a murine model of radiation-induced nephropathy by renal scintigraphy. At first, the appropriate therapy activity to induce nephropathy was...

Infantile hydronephrosis detected by ultrasonography poses a clinical dilemma on how to treat the condition. This article reports a retrospective study to evaluate infantile hydronephrosis due to suspected ureteropelvic junction (UPJ) obstruction by means of standardized diuretic renography and to speculate its usefulness for quantitative assessment and management of this condition. Between Nov...

A 22-year-old female patient with severe hypertension underwent both Technetium-99m diethylenetriaminepentaacetate and Technetium-99m mercaptoacetyltriglycine basal and captopril renal scintigraphy. While no significant change was seen with Tc-99m DTPA, there was left sided parenchymal retention of captopril Tc-99m MAG3 suggesting renal artery stenosis which was confirmed by angiography.
