Characteristics and reproducibility of the arterial input function (AIF) derived from dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) studies and its effect on renal functional parameters
نویسندگان
چکیده
Purpose: The aim of this study was to investigate parameters of the aortic input function (AIF) in dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) of the kidney and its effect on renal functional parameters (perfusion and glomerular filtration rate) calculated using a two-compartment model analysis. Inter-observer agreement, effect of size of region of interest (ROI) in the aorta and reproducibility in DCE-MRI studies have been evaluated.

Background: Salivary gland tumors form nearly 3% of head and neck tumors. Due to their large histological variety and vicinity to facial nerves, pre-operative diagnosis and differentiation of benign and malignant parotid tumors are a major challenge for radiologists. Objective: The majority of these tumors are benign; however, sometimes they tend to transform into a malignant form. Functional M...
