Objectives

Narrative objectives1

To verify that dynamic SPECT imaging with the StarGuide dedicated SPECT system can reproduce the examinations conventionally performed with renal scintigraphy.

Basic objectives2

Others

Basic objectives -Others

This is a technical verification study and does not aim to evaluate clinical efficacy or safety. We will confirm whether dynamic SPECT with the StarGuide system can reproduce key metrics of conventional renal scintigraphy (TAC, ERPF, GFR, differential renal function, excretion patterns).

Confirmatory

Trial characteristics_2


Developmental phase



Assessment

Primary outcomes

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

Interventions/Control_1

Patients who have undergone conventional renal scintigraphy will additionally undergo dynamic imaging using the dedicated SPECT system StarGuide with 99mTc-DTPA or 99mTc-MAG3, in order to confirm the feasibility of acquiring dynamic renal SPECT images. The radiopharmaceutical and imaging protocol for renal scintigraphy will be the same as those conventionally used. Clinical examinations of the patient will be conducted both before and after administration.
