[Validation of the renogram with immediate diuretic stimulus].

Objective: The aim of this study is to determine the diagnostic reliability of the renogram with diuretic stimulus simultaneously at the administration of the dose, comparing two groups of 59 patients each one (F0 and F+10), to select patients for surgery.

Material And Methods: This is an retrospective study about two groups of 59 patients to whom the diuretic renogram was carried out by stimulus (furosemide), by suspicion of ureteropelvic or vesicoureteral obstruction, using (99m)Tc-Mercaptoacetylglicine. In the first one, the study was conducted applying the diuretic stimulus 600 seconds after the administration of the dose of the radiotracer (F+10).

Iodine-131 treatment of thyroid papillary carcinoma in patients undergoing dialysis for chronic renal failure: a dosimetric method.

Until recently, the therapeutic protocol widely accepted for ablation of the thyroid remnant and for metastases of thyroid papillary carcinoma was the administration of 131I after surgery. However, at present, some data question the usefulness of such treatment in patients considered low risk. The treatment with radioiodine in patients suffering from end-stage renal disease (ESRD) undergoing hemodialysis requires controlled dosages and individualized administration guidelines.

Scapular hibernoma fortuitously discovered on myocardial perfusion imaging through Tc-99m tetrofosmin.

A 49-year-old man was hospitalized for precordial pain. The result of a resting electrocardiograph was normal. Tc-99m tetrofosmin stress myocardial imaging was performed and uptake in the area of the left scapula was seen.
