MRI endoscopy at 3T
نویسندگان
چکیده
Introduction: Until now MRI could not perform traditional endoscopy from the viewpoint of an internal probe because localization depended entirely on the fixed external gradient system and was hence intrinsically locked to the laboratory frame-of-reference (FoR). A method for high-resolution MRI using active internal probes that utilizes the spatial properties of the probe itself, for MRI has been proposed [1]. Because these properties are intrinsic to the probe, they move with it, transforming the MRI FoR from the laboratory to the device, creating a true MRI endoscope. The endoscope has been reduced to safe practice at 3T yielding high resolution (100μm) intravascular images.

Accelerated, motion-corrected high-resolution intravascular MRI at 3T.
Audience: Interventionalists, and those interested in atherosclerosis and intravascular MR imaging. Purpose. Current speeds for intravascular (IV) MRI and MRI endoscopy are limited to ~2frames/s at 3T, rendering high-resolution (~100μm) images susceptible to degradation by physiological motion on the order of mm/ms. Here, using projection reconstruction we: (A) reduce sensitivity to motion from...
متن کاملMRI-guided breast biopsy at 3T using a dedicated large core biopsy set: feasibility and initial results.
OBJECTIVE The increasing importance of breast MRI in the diagnostic processes concerning breast cancer yield often lesions that are visible on MRI only. To assess the nature of these lesions, pathologic analysis is necessary. Therefore, MR-guided biopsy should be available. Breast MRI at 3T has shown advantage over 1.5T. Unfortunately, current equipment for MR-guided biopsy is better suited for...
متن کاملPre-surgical epilepsy evaluation using 3T MRI. Do surface coils provide additional information?
PURPOSE To assess if 3T MRI can be further improved by adding surface coil imaging, in the context of detection and characterization of cerebral lesions in patients with drug-resistant epilepsy. METHODS Twenty five patients with drug-resistant epilepsy undergoing evaluation for epilepsy surgery were examined with high resolution 3T MRI. The patients were MRI-negative (n = 15), or had unclear ...
متن کاملDynamic contrast-enhanced MRI in the liver at 3T with dual-input pharmacokinetic model analysis
Introduction DCE-MRI has been widely used at 1.5T in a variety of organs and tissues. The aim of this study was to assess the feasibility of DCE-MRI in the liver at 3T, taking into account the challenges of 3T systems, and performed in such a way as to allow a dual-input pharmacokinetic analysis, separating the perfusion contributions from the hepatic artery and portal vein. To our knowledge, t...
متن کاملAcceleration and motion-correction techniques for high-resolution intravascular MRI.
PURPOSE High-resolution intravascular (IV) MRI is susceptible to degradation from physiological motion and requires high frame-rates for true endoscopy. Traditional cardiac-gating techniques compromise efficiency by reducing the effective scan rate. Here we test whether compressed sensing (CS) reconstruction and ungated motion-compensation using projection shifting, could provide faster motion-...
