“…Over the past few decades, quantitative studies have been employed to evaluate kidney function. Although ultrasound is often the primary choice for an initial assessment, follow-up, and monitoring of kidney transplants, scintigraphy has an advantage and can provide better information on kidney function [ 13 - 15 , 17 , 18 ]. In addition, according to research cited in the literature, there is no agreement on the resistance index (RI).…”

“…In addition, according to research cited in the literature, there is no agreement on the resistance index (RI). Some studies have demonstrated that RI was a reliable marker to assess kidney function [ 12 - 14 ], but others have shown the opposite [ 11 , 16 - 18 ]. Hence, more research needs to be done to test RI before it can be recommended for use in clinical centres.…”

“…In the last decade, quantitative studies have evaluated kidney function using ultrasound [ 7 , 11 - 18 ], CT [ 19 - 21 ], radionuclide imaging [ 14 , 17 - 24 ], and MRI [ 25 - 28 ]. Previous studies have yielded promising results.…”

PurposeEarly detection and monitoring of kidney function during the post-transplantation period is one of the most important issues for improving the accuracy of an initial diagnosis. The aim of this study was to evaluate texture analysis (TA) in scintigraphic imaging to detect changes in kidney status after transplantation.Material and methodsScintigraphic images were used for TA from a total of 94 kidney allografts (39 rejected and 55 non-rejected). Images corresponding to the frames at the 2nd, 5th, and 20th minute of the study were used to determine the optimum time point for analysis of differences in texture features between the rejected and non-rejected allografts.ResultsLinear discriminant analysis indicated the best performance at the fifth minute frame for classification of the rejected and non-rejected allografts with receiver operating characteristic curve (Az) of 0.982, corresponding to 91.89% sensitivity, 96.49% specificity, and 94.68% accuracy. Also, TA can differentiate acute tubular necrosis from acute rejection with Az of 0.953 corresponding to 88% sensitivity, 92.31% specificity, and 90.62% accuracy at the 5th minute frame. The best correlation between texture feature and kidney function was achieved at the 20th minute frame (r = –0.396) for glomerular filtration rate.ConclusionsTA has good potential for the characterisation of kidney failure after transplantation and can improve clinical diagnosis.

“…Moreover, PET and SPECT were proved to be able to detect hepatic, cardiac and pulmonary fibrosis (Désogère et al, 2017;Kim et al, 2016;Li et al, 2011). Additionally, scintigraphy has succeeded to early predict renal reduced function after transplantation (Yazici et al, 2015(Yazici et al, , 2013Yoon et al, 2016), with an improvement of prediction power when coupled with CT (Lovinfosse et al, 2016). Recently, nuclear medicine has been demonstrated to be a noninvasive tool in the quantitative assessment of glomerular function (Qin et al, 2019).…”
