Does correction of frequency drift induced by gradient heating in 1H spectra using interleaved reference spectroscopy?
If spectroscopy scans are combined with imaging scans with a high gradient duty cycle such as diffusion-weighted imaging or functional MRI, a drift correction with IRS can considerably improve the validity of data analysis in research studies.
In this swine CA model, where defibrillation was first attempted at 10 minutes of untreated ventricular fibrillation, uninterrupted chest compressions resulted in significantly higher survival rates and higher 24-hour neurologic scores, compared with standard 30:2 CPR.
