Indications for 99mTc-DMSA Imaging
| No. | Indication |
|---|---|
| 1 | Detection of permanent renal parenchymal scarring |
| 2 | Detection of acute pyelonephritis |
| 3 | Detection of parenchymal damage after trauma |
| 4 | Characterization of structural renal abnormalities: for example, solitary kidney, duplex kidney, small kidney, dysplastic kidney, horseshoe kidney |
| 5 | Detection of ectopic renal tissue, including cross-fused renal ectopia |
| 6 | Quantitation of differential (split) renal function |
| 7 | Confirmation of nonfunctional multicystic dysplastic kidney |
| 8 | Evaluation of unexplained hypertension when there is clinical suspicion for renal disease such as dysplasia or scarring |
| 9 | Evaluation of renal parenchymal function in patients with renovascular hypertension before and after revascularization procedures |
| 10 | Renal parenchymal function regional assessment in patients with complex renal calculi before and after treatment |
| 11 | Surgical decision-making for ureteropelvic junction obstruction or refractory vesicoureteral reflux based on differential renal function |
| 12 | Evaluation of renal parenchyma when there is allergy to iodinated CT contrast, and MRI is unavailable/contraindicated (18) |
