Scheme for studying and describing a radionuclide kidney examination

1. Based on the renography results, determine for each Kidney:

- the height of the vascular segment (mm);

- the height of the maximum curve peak;

- the time to reach the peak height (min);

- the half-excretion period (T1/2) of the radiopharmaceutical agent (RPA), determined by the time required for the curve height to decrease by 50% from the maximum peak;

- determine the type of renogram: normal, obstructive, parenchymal, isosthenuric, afunctional, reflux;

Conclusion: formulate separately for the left and right Kidneys.

2. Based on the renoscintigraphy data, determine:

- kidney position: normal or displaced (dystopia);

- kidney shape: bean-shaped, oval, spherical, indeterminate;

- dimensions of each kidney;

- contour characteristics: distinct or indistinct (blurred), regular or irregular (bosselated);

- character of RPA accumulation in the kidneys: uniform or non-uniform, with the presence of "cold" foci, indicating their number, size, and localization.

Conclusion: kidneys without pathological changes, or renal involvement (diffuse, localized, absence of a kidney, or other changes).
