“…There are several methods to assess renogram patterns such as measuring height and angle of the initial rise of the curve, but we preferred to use the method suggested by Steward and Hayne (1962) by measuring T max. and T % due to its simplicity and maximum diagnostic accuracy which can be obtained by measuring these parameters only.…”

“…By itself the usual accuracy of about 60-80% is somewhat inadequate (Maxwell et al, 1968;Meier & Beierwaltes, 1966;Stewart & Haynie, 1962). However, in conjunction with other tests, the renogram can be helpful.…”

Summary The use of radioactive labels for tracers is an important part of the investigation of renal disease. These techniques seldom replace, but often complement radiographic techniques. Generally, the radionuclide methods provide functional and dynamic information in a non-invasive, non-traumatic type of examination. The examinations usually are relatively simple to perform and carry a very low risk of untoward reaction. The past decade has seen significant advances in radiopharmaceutical design and instrumentation. It is expected that the next decade will produce an even greater advance in this field.

“…At dmes, there may be a difference between the right and the left renogram without any demonstrable cause. Similarly, there may be a unilateral arterial stenosis without differences in the two renograms (1,2,4,9,12).…”

“…Some authors perform the renography with the patient in the horizontal position (4,9,11), while others use a sitting position (7,8), so there is not agreement concerning the preferred position. Accord ing to several workers (8,11), however, the positioning does influence the shape of the curve.…”

The reproducibility of the three parameters used in isotope renography (T/2 = time from the maximum until half the radioactivity over the kidney had been attained; t = time from injection until the maximum value was attained; and the maximum value) was studied in 41 patients by repeat tests in the same position. The influence of patient position to the same three parameters was also studied in 61 patients investigated in sitting and prone position. The values could be reproduced in 70–98% of the patients in the same position with a fairly wide definition of the concept reproducibility. Patient position was of no significance to the reproducibility. When changing from the sitting to the prone position, the maximum value decreased, while T/2 and t did not show any systematic alteration. A disparity between the function of the two kidneys was demonstrated with the same frequency in the sitting and prone position. This disparity between the two sides was more easily reproducible when X-ray examinations revealed unilateral renal disease. It is concluded that the reproducibility in isotope renography is not fully satisfactory. In the event of a disparity between the two sides the test should be repeated, and if there is a clinical or radiological suspicion of unilateral renal disease, one normal isotope renography should not be relied on, but the test repeated.
