Hemodialysis AV Fistula: What a Radiologist Should Know?
Hemodialysis works as a lifeline for end stage renal disease patients. Creation and maintenance of vascular access for dialysis is the mammoth task. Due to increased references related to vascular access; number of complications are faced in pre as well as post operative period of vascular access creation. Ultrasound and color Doppler study play a major role in imaging throughout this period. Pre operative vascular mapping is very crucial to help surgeon to determine the proper site and surgical technique for vascular access creation. Early and delayed post operative complications can also be diagnosed with ultrasound and color Doppler study. Here we have tried to cover all the important points which a radiologist should consider during pre operative vascular mapping and post operative evaluation of vascular access as well as any associated complications.

Current Imaging Techniques in Renal Cell Carcinoma
Renal cancers are one of the 10 most commonly seen cancers in both sexes. The incidence of renal cancers is high in Western developed countries and lower in Eastern and developing countries. The overall incidence of malignancy has been increasing in recent times. Ultrasound (USG) is very commonly used imaging technique; however recent advances like contrast enhanced ultrasound helps to differentiate various cystic renal masses. Availability of newer imaging techniques such as Computed tomography scan (CT scan) and Magnetic resonance imaging (MRI) and their various applications may play a role in better and early diagnosis of such lesions. Due to its highly metastatic nature, accurate staging is more important to facilitate proper treatment. Fluoro-deoxyglucose positron emission tomography (FDG PET) is widely applied in detection, staging/restaging and surveillance of such lesions. In this chapter, we will try to cover the recent advances in various modalities for detection of renal cancers, particularly renal cell carcinoma (RCC).
