Study Notes
Static Renal Imaging
- Imaging Agent: Tc99m-succimer (1-6 mCi [37-222 MBq])
- Imaging Purpose: Assess renal cortex outline, size, shape, and contour to evaluate healthy renal tissue.
- Imaging Procedure: Posterior projection images, including left and right posterior obliques, taken 2-3 hours after a flow study.
- Normal Findings: Smooth renal outlines, consistent tracer uptake, and consistent tracer distribution throughout both kidneys.
- Abnormal Renal Findings: Congenital abnormalities like horseshoe kidney, ectopic kidney, and absence of one or both kidneys.
Horseshoe Kidney
- Description: Located in the pelvic region, anterior to the normal position, due to incomplete separation of the two kidneys during fetal development.
