Acquisition
- Use gammacamera with paralell high resolution collimator for imaging.
- Obtain a dynamic study for perfusion and glomerular filtration phase. If retention is present, inject furosemide 1 mg/kg (maximun = 40 mg) iv at 15 min to characterize response whether functional or obstructive. This is also valid in the captopril renogram. In the latter case, check the blood pressure at the end of the procedure before discharging the patient. Administer iv fluids if marked hypotension ensues.
- Delay images at 2 h are optional and may be useful in patients with obstructive uropathy.
