Signal-to-noise ratio for hyperpolarized ³He MR imaging of human lungs: a 1.5 T and 3 T comparison.
The signal-to-noise ratio in hyperpolarized noble gas MR imaging is expected to be independent of field strength at frequencies typical of clinical systems (e.g., 1.5 T), where body noise dominates over coil noise. Furthermore, at higher fields (e.g., 3 T), the SNR of lung images may decline due to decreases in T(2) originating from increases in susceptibility-induced field gradients at the air...
متن کاملHyperpolarized Noble Gas MR Imaging SNR comparison between 73.5 mT and 3 T in Rat Lung
Introduction In Hyperpolarized Noble Gas (HNG) MR imaging (i.e.Xe and He), the available magnetization is independent of magnetic field strength. Above a cut-off Larmor frequency when the sample (i.e. body) noise dominates the RF coil noise [1], the signal-to-noise ratio (SNR) is expected to decrease with field for band-matched imaging due to a reduction in the transverse relaxation time, T2* [...
متن کاملReducing SAR and enhancing cerebral signal-to-noise ratio with high permittivity padding at 3 T.
Previous works have shown that placement of a high-dielectric pad can improve image intensity in a region adjacent to the pad, or that placement of dielectric pads around a large surface of the head can improve image homogeneity on an entire plane through the head in high-field MRI. Here, experimental results show that use of high-dielectric pads around the human head can reduce the required in...

متن کاملPreparation and characterization of a novel nanobody against T-cell immunoglobulin and mucin-3 (TIM-3)
Objective(s): As T-cell immunoglobulin and mucin domain 3 (TIM-3) is an immune regulatory molecule; its blocking or stimulating could alter the pattern of immune response towards a desired condition. Based on the unique features of nanobodies, we aimed to construct an anti-TIM-3 nanobody as an appropriate tool for manipulating immune responses for future therapeutic purposes. Materials and Meth...
