Controlled aliasing in 3D parallel imaging (2D CAIPIRINHA)

Controlled aliasing in volumetric parallel imaging (2D CAIPIRINHA).

The CAIPIRINHA (Controlled Aliasing In Parallel Imaging Results IN Higher Acceleration) concept in parallel imaging has recently been introduced, which modifies the appearance of aliasing artifacts during data acquisition in order to improve the subsequent parallel imaging reconstruction procedure. This concept has been successfully applied to simultaneous multi-slice imaging (MS CAIPIRINHA). I...

Controlled Aliasing In Parallel Imaging

Recently a new parallel imaging strategy, Controlled Aliasing In Parallel Imaging Results IN Higher Acceleration (CAIPIRINHA), was introduced, which modifies the appearance of the aliasing artifacts during the acquisition in order to improve the following parallel imaging reconstruction procedure. This concept was successfully applied to simultaneous multi-slice imaging (MS-CAIPIRINHA) [1] and ...

Optimizing the undersampling scheme of 2D Controlled Aliasing in Parallel Imaging Results in a Higher Acceleration (CAIPIRINHA) in Abdominal Imaging using 3D g-factor map: A phantom study

Fast MR Imaging of the Paediatric Abdomen with CAIPIRINHA-Accelerated T1w 3D FLASH and with High-Resolution T2w HASTE: A Study on Image Quality

The aim of this study was to explore the applicability of fast MR techniques to routine paediatric abdominopelvic MRI at 1.5 Tesla. "Controlled Aliasing in Parallel Imaging Results in Higher Acceleration-" (CAIPIRINHA-) accelerated contrast-enhanced-T1w 3D FLASH imaging was compared to standard T1w 2D FLASH imaging with breath-holding in 40 paediatric patients and to respiratory-triggered T1w T...

Improvements in multislice parallel imaging using radial CAIPIRINHA.

Multislice parallel imaging involves the simultaneous sampling of multiple parallel slices which are subsequently separated using parallel imaging reconstruction. The CAIPIRINHA technique improves this reconstruction by manipulating the phase of the RF excitation pulses to shift the aliasing pattern such that there is less aliasing energy to be reconstructed. In this work, it is shown that comb...
