=Abstract
Purpose : The purpose of this study is for quantitative(absolute uptake & mean relative
uptake) analysis of renal uptake rates using LEM Gamma Camera motion correction for
breathing.
Methods : We studied from Sep 2005 to Nov 2005 at department of nuclear medicine
SNUH (Seoul National University Hospital) visited 28 patients, for 99mTc-DMSA renal
scan. We used the LEHR-PAR collimator, 256*256 word mode, 500k count, Mag 1.0
,counting for 60sec, LEM gamma camera.
To acquire renal uptake rates of 99mTc-DMSA at 3-5hours after intravenous injection,
We analyzed for the quantified renal uptake rates between motion correction and
unmotion.
Results : The value is quantitative analysis of 99mTc-DMSA Scan using motion
correction. absolute uptake appear that motion correction(mean±SD): LT 24.19±10.05, RT
23.92±9.92, unmotion correction(mean±SD): LT 24.37±10.27, RT 24.01±9.70, and mean
relative uptake motion correction(mean±SD): LT 50.60±17.41, RT 49.33±17.40 unmotion
correction(mean±SD): LT 50.46±17.30, RT 49.40±17.30. When we compared two group
with paired T-test, all values were over 0.05. There is no signification difference.
Conclusion : We examined the influence on the moving of the kidney for breathing. To
acquire renal uptake rates of 99mTc-DMSA at 3-5hours after intravenous injection, We
analyzed for the quantified renal uptake rates between motion correction and motion. All
values using paired T-test analysis showed over 0.05. This study result have not an effect
on quantitative(absolute uptake & mean relative uptake) analysis of renal uptake rates
using LEM gamma camera motion correction for breathing.
Key words : paired T-test, motion correction, absolute uptake, mean relative uptake
