Femoral Artery Vessel Wall Imaging Using Contrast-enhanced, Susceptibility Weighted Imaging
Introduction: Double Inversion Recovery or Saturation Band Black Blood imaging has been used to image vessel wall morphology and plaque composition. However, due to their reliance on blood inflow, problems arise at areas with slow or in-plane flow. Recently, the feasibility of vessel wall imaging using a flow-insensitive technique, Susceptibility Weighted Imaging (SWI), has been demonstrated [1...
متن کاملImaging the vessel wall in major peripheral arteries using susceptibility-weighted imaging.
PURPOSE To demonstrate a novel contrast mechanism for imaging the vessel wall and vessel wall calcification using susceptibility-weighted imaging (SWI). MATERIALS AND METHODS Eighteen subjects were imaged with multidetector computed tomography (MDCT) and high-resolution SWI at 3T. The SWI imaging parameters were optimized to allow for the best visualization of the femoral artery lumen and the...
متن کاملIntracranial arterial wall imaging using high-resolution 3-tesla contrast-enhanced MRI.
BACKGROUND Conventional arterial imaging focuses on the vessel lumen but lacks specificity because different pathologies produce similar luminal defects. Wall imaging can characterize extracranial arterial pathology, but imaging intracranial walls has been limited by resolution and signal constraints. Higher-field scanners may improve visualization of these smaller vessels. METHODS Three-tesl...
متن کاملHemorrhagic myocardial infarction: detection using susceptibility weighted phase imaging
In this study we determined the normal range of highpass filtered image phase values in a group of normal subjects for all sixteen segments of the heart. The range and standard deviations varied significantly across the heart, with less variance in septal segments. In a group of acute myocardial infarction patients, phase values in hemorrhagic myocardial infarction were significantly less than ...
متن کاملcontrast enhanced magnetic resonance imaging in sacroiliitis
conclusion fs t2 w and ce fs t1 w sequences of axial planes were the most useful sequences in determination of active sacroiliitis. therefore, in patients with renal failure or allergy to contrast media, fs t2 wi can be obtained to detect active sacroiliitis. objectives the aim of this retrospective study was to assess the value of different magnetic resonance imaging (mri) sequences in evaluat...
