OBJECTIVE The objective of this article is to provide a practical illustrated review of PET/CT in the imaging evaluation of transitional cell carcinoma. CONCLUSION Local evaluation of the primary tumor in patients with transitional cell carcinoma on PET is often limited by the obscuring effect of excreted FDG, but assessment of metabolic activity may(More)
OBJECTIVES Sonography is a noninvasive, office-based diagnostic tool often used for evaluation of subfertile men. Previous studies have suggested that a resistive index (RI) greater than 0.6 is associated with impaired spermatogenesis. We sought to validate this threshold in a urologic patient population presenting for infertility evaluation. METHODS We(More)
Biometric identification system has high efficiency, high recognition rate and comfortable to the user's operating characteristics. Palmprint recognition is considered the most viable and reliable biometric recognition technique owing to its merits, such as low cost, user friendliness, high speed and high accuracy. Region-of-Interest (ROI) segmentation of(More)
OBJECTIVE To determine if a correlation exists between the semiquantitative bone scintigraphy index (SQBSI) and serum tartrateresistant acid phosphatase 5b (TRACP5b) activity, a novel osteoclast marker that has been shown to be useful for monitoring bone metastasis in breast cancer (BC) patients. PARTICIPANTS AND METHODS Among patients enrolled in 2(More)
PURPOSE To evaluate predictive factors for compensatory hypertrophy and renal outcomes in a large cohort of patients with multicystic dysplastic kidneys (MCDK). MATERIALS AND METHODS We conducted a retrospective review from 1997 to 2016. Contralateral kidney and MCDK length were recorded from all ultrasounds as well as creatinine when available. We used(More)
PURPOSE To analyze preoperative predictive factors for intraoperative balloon dilation in semirigid ureteroscopic lithotripsy. PATIENTS AND METHODS We retrospectively reviewed data from 397 consecutive semirigid ureteroscopic lithotripsies performed in 389 patients with ureteral stones at our institution during the calendar year 2010. Preoperative(More)
In this paper, an efficient novel strategy simulating time scenes of an o utdoor scene is introduced. It is a hybrid approach combining the multiple regression in statistic, the discrete cosine transform, and a look-up table algorithm. First, several color-block images taken at different times of a day were used as the testing images to create the reference(More)
BACKGROUND The aim of this study is to evaluate whether geographic variations in the prevalence of late-stage chronic kidney disease (CKD) exist and are associated with incidence rates of renal cell carcinoma (RCC), upper tract urothelial carcinoma (UTUC), or lower tract urothelial carcinoma (LTUC). METHODS Prevalence rates of late-stage CKD for 366(More)
