Non Contrast Enhanced (NCE)-MRA of the Renal Transplant Vessels: A comparison between IFIR and VIPR-SSFP
Purpose: To compare the utility of two non-contrast enhanced MR angiographic (NCE-MRA) techniques for visualization of the renal transplant vessels. Introduction: There has been renewed interest in the development of NCE-MRA methods to image the renal transplant vasculature due to recognition of gadolinium contrast agents as major risk factors for Nephrogenic Systemic Fibrosis in patients with ...
متن کاملNon-Contrast Enhanced Pulmonary Vein MRA with Compressed Sensing
INTRODUCTION: Pulmonary vein (PV) MR angiography (MRA) is commonly used for assessment of PV anatomy in patients undergoing PV isolation for treatment of atrial fibrillation. Clinically, PV MRA is performed during the first pass injection of gadolinium (Gd) contrast agents. Non-contrast PV MRA is an alternative to the contrast-enhanced technique for patients with renal insufficiency due to rece...
متن کاملFeasibility of non-contrast-enhanced four dimensional (4D) MRA in head and neck tumors, comparison with contrast-enhanced 4D MRA
BACKGROUND Information of tumor vascular architecture and hemodynamics is important in treating patients with head and neck tumors (HNTs). The purpose of this study is to investigate the feasibility of non-contrast-enhanced four-dimensional magnetic resonance angiography (non-CE 4DMRA) using arterial spin labeling for anatomical and hemodynamic evaluation of vascularity of head and neck tumors....
متن کاملInhance (Inflow Inversion Recovery) Non-contrast Renal MRA: Comparison with 3D Gadolinium Enhanced MRA in Clinical Patients
Purpose: Contrast-enhanced MR Angiography (CE-MRA) is a widely accepted technique for evaluation of the renal arteries; however, recent concerns regarding the development of nephrogenic systemic fibrosis (NSF) after gadolinium contrast agent administration in patients with reduced renal function have emphasized the need for robust non-contrast MRA methods. One such technique is steady state fre...
متن کاملNon-Contrast MRA
Introduction In MR angiography (MRA), techniques are mainly divided into contrast-enhanced MRA and non-contrast MRA. Various non-contrast MRA techniques are clinically useful and widely used in routine examinations, such as 3D TOF [1] in intracranial region, phase shift [2] for flow quantification, arterial spin labeling [3,4] in pulmonary vessels [5,6], and balanced SSFP [7] in bright blood ca...
