Inclusion criteria
Inclusion criteria: Patients who have provided written informed consent to participate in this study Patients scheduled to undergo, or who have undergone, renal scintigraphy with 99mTc-DTPA or 99mTc-MAG3 for clinical renal function assessment Adults aged 20 years or older Individuals judged eligible for participation by the principal investigator or sub-investigator
Exclusion criteria
Exclusion criteria: Patients who are pregnant or potentially pregnant Patients who are expected to have difficulty remaining still during imaging Patients whom the principal investigator judges to be inappropriate for participation in this study (e.g., when any therapeutic intervention for the kidneys has been performed between the initial renal scintigraphy and the imaging in this study)
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Verification that the renal time-activity curves obtained from dynamic SPECT imaging with StarGuide are comparable to those from conventional renal scintigraphy. Consistency between the two methods in the following renal function parameters: Effective renal plasma flow (ERPF) Glomerular filtration rate (GFR) Excretion patterns Differential renal function values | — |
