Abstract
|
|
|
To Assessment of the quantified renal uptake rates in every 99mTc-DMSA scan tests of patients is actually difficult because of time consumption and complicated calculations required to measure the correct dose of the infused radionulide and
radiation
decay, the adjustment for the depth of kidney and the subtraction of backgraound count. We've formulated two regression models for the quantified renal uptake rates [I] from the simple renal uptake rates [H] with a square shaped ROI
(Region-Of-Interest)
in 25 cases (Group 1) and with a kidney shaped ROI in 37 cases (Group 2), respectively. The regression model for the Group 1 was [I]1=0.885 [H]1-4.575 (P<0.005), and for the Group 2 was [I]2=0.591 [H]2-2.105 (P<0.005).
The formal charts were clinically convenient to evaluate the individual renal functions in patients with 99mTc-DMSA renal scan.
