[ camera based calculation of 99mTc-MAG3 clearance using conjugate views method]

ABSTRACT

Background: measurement of absolute or differential renal function using radiotracers plays an important role in the clinical management of various renal diseases. Gamma camera quantitative methods in approximation of renal clearance may potentially be as accurate as plasma clearance methods. However some critical factors such as kidney depth and background counts are still troublesome in the use of this technique. In this study the conjugate-view method along with some background correction techniques have been used for the measurement of renal activity in 99mTc-MAG3 renography. Transmission data were used for attenuation correction and the source volume was considered for accurate background subtraction
