Retrospective motion correction through multi-average k-space data elimination (REMAKE) for free-breathing cardiac cine imaging.

Purpose: To develop a motion-robust reconstruction technique for free-breathing cine imaging with multiple averages.

Method: Retrospective motion correction through multiple average k-space data elimination (REMAKE) was developed using iterative removal of k-space segments (from individual k-space samples) that contribute most to motion corruption while combining any remaining segments across multiple signal averages. A variant of REMAKE, termed REMAKE+, was developed to address any losses in SNR due to k-space information removal.

Simultaneous multislice steady-state free precession myocardial perfusion with full left ventricular coverage and high resolution at 1.5 T.

Purpose: To implement and evaluate a simultaneous multi-slice balanced SSFP (SMS-bSSFP) perfusion sequence and compressed sensing reconstruction for cardiac MR perfusion imaging with full left ventricular (LV) coverage (nine slices/heartbeat) and high spatial resolution (1.4 × 1.4 mm ) at 1.

Use of rapid cardiac magnetic resonance imaging to guide chelation therapy in patients with transfusion-dependent thalassaemia in India: UMIMI study.

Aims: To explore the impact of incorporating a faster cardiac magnetic resonance (CMR) imaging protocol in a low-middle-income country (LMIC) and using the result to guide chelation in transfusion-dependent patients.

Methods And Results: A prospective UK-India collaborative cohort study was conducted in two cities in India. Two visits 13 months apart included clinical assessment and chelation therapy recommendations based on rapid CMR results.

Quantification of balanced SSFP myocardial perfusion imaging at 1.5 T: Impact of the reference image.

Purpose: To investigate the use of a high flip-angle (HFA) balanced SSFP (bSSFP) reference image (in comparison to conventional proton density [PD]-weighted reference images) for conversion of bSSFP myocardial perfusion images into dynamic T maps for improved myocardial blood flow (MBF) quantification at 1.5 T.

Methods: The HFA-bSSFP (flip angle [FA] = 50°), PD gradient-echo (PD-GRE; FA = 5°), and PD-bSSFP (FA = 8°) reference images were acquired before a dual-sequence bSSFP perfusion acquisition.

Comparative study of forage toxic metals of conventional versus non-conventional pastures in relation to animal mineral nutrient allowance.

At present, the forage production is the foundation of beef cattle and sheep industries in graziery. This study was designed to assess the toxic metal composition of the conventional pastures and non-conventional pastures in consideration of mineral needs of ruminants. At all the surveyed sites, these mean soil metal concentrations were measured to be higher or lower than the referred threshold levels.
