Norwich GFR Assessment System

Norwich GFR is a teaching clinical utility app designed for nuclear medicine professionals to learn how to accurately assess glomerular filtration rate (GFR) using the plasma clearance technique. GFR is a critical marker of renal function, particularly valuable in situations where precise kidney evaluation is required. The app supports the common use of Tc-99m DTPA as a radiopharmaceutical agent, enabling users to estimate renal filtration performance from timed blood sample measurements following tracer injection. Use cases in teaching and training include: Pediatric renal evaluation Preoperative assessment prior to nephrectomy Renal transplant follow-up Oncology: patient eligibility for nephrotoxic chemotherapies (e.g., cisplatin, carboplatin) Whether in a hospital setting or research environment, Norwich GFR simplifies data entry, streamlines workflow, and helps ensure accurate interpretation of GFR results.
