Multimodal technologies combining different physical principles have enhanced medical imaging, diagnostic, treatment and monitoring tasks [1]. In hybrid devices, MRI systems are often integrated for their excellent soft-tissue contrast and multidimensional structural and morphological information. Unfortunately, they require cryogenic refrigeration, they are bulky, heavy, environmentally...
Background: Performing hyperpolarized-13C MRI, knowledge of T2 values plays an important role for the sake of correct quantification of the metabolites (pyruvate, lactate, and bicarbonate) to increase the SNR and optimize image interpretation.
Aim(s): To estimate T2 values of pyruvate and lactate in both healthy and ischemic porcine kidneys at different concentrations...
Introduction: Respiratory motion affects the reconstructed spectra in magnetic resonance spectroscopic imaging (MRSI), as it changes the location of the nuclei and the B0 field they experience during the signal acquisition. B0 changes lead to a frequency shift of the acquired signal. This study aimed to determine the maximum frequency shift due to respiratory motion in a typical 31P liver...
Quantitative relaxometry and fat fraction mapping at ultrahigh field are important areas of research, hindered by the significant challenges imposed by the high field inhomogeneities. Here, we used a modified MR Fingerprinting scheme based on a spectral-spatial excitation to obtain robust water T1/T2 quantification and fat fraction mapping of the lower extremities of a healthy volunteer within...
