Kadalie, Emile. "Development of multi-parametric human MRI at 3T". Electronic Thesis or Diss., Bordeaux, 2023. http://www.theses.fr/2023BORD0493.
Testo completoMagnetic Resonance Imaging (MRI) is a method of choice for the diagnosis, prognosis and monitoring of pathologies in soft tissues. Indeed, strong contrasts between tissues are obtained and can be modulated on demand. This imaging technique has not shown any harmful influence, enabling repetitive high-resolution exams.Quantitative MRI (qMRI) has become incredibly interesting these last ten years, as it provides maps in which each pixel contains a measurement of a physical parameter. As such, contrarily to conventional images obtained on a gray scale, this MR quantification can be employed to obtain objective interpretations of the images, and to provide a scale for comparing time points and patients.Among the physics parameters that can be quantified, the longitudinal (T1) and the transversal (T2) relaxation times are the most common.The Dual Echo Steady State (DESS) sequence has often been used in musculo-skeletal MRI to rapidly obtain high-contrast morphological images and 3D quantitative T2 mapping. By acquiring two distinct steady-state free precession echoes, two images with different contrasts are built, whose ratio can be used to procure T2 maps by matching it to a computed dictionary of many simulated signals. Nonetheless, the sequence has often been described as sensitive to physiological motion, generating artifacts as well as discrepancies in T2 values. Consequently, the main objective of my work was to implement a rapid 3D DESS sequence for brain imaging that enables T2 estimation accurately and with high repeatability at 3T.To do so, I first identified the cause of the ghosting artifact present in the DESS brain images, through the insertion of a Self-Gating (SG) module. As, its phase was correlated to the signal retrieved from a respiratory belt, B0 variations due to breathing were consequently identified as the source of the ghosting on the brain images.To correct this artifact, a Compressed Sensing dedicated trajectory was implemented so as to retrospectively bin the data into multiple respiratory phases, and reconstruct undersampled k-spaces into images with high quality. To increase the repeatability of the method, the conventional Cartesian encoding was replaced by a Spiral Cartesian encoding, which further distributed the artifact as noise on the images. 3D T2 maps were then acquired with a spatial resolution of 1.2mm isotropic, and were of high quality and repeatable on all the volunteers.The new methodology was then implemented on a 1.5T and a 7T Siemens scanners. This proved that the corrected DESS method set in place during this PhD can be used on images obtained from different scanners, and different magnetic fields.Despite these improvements, the brain T2 values remained short compared to a Spin-Echo sequence. To investigate this issue, several simulations were performed and highlighted the influence of B0 variations in the T2 errors, as well as the high sensitivity to short T2 components. To correct the measurements, a dictionary taking into account multiple B0 variations was created. This will be useful in the case where the DESS sequence is applied on a moving organ like the liver.Also, as additional sequences have to be inserted into the protocol to correct the T2 measurements, a simultaneous T1 and T2 estimation was investigated. To reach this goal, the gradient echo trains within the MP2RAGE sequence were replaced by DESS trains. Sequence parameter optimization was explored via the Cramer Rao Lower Bound method so as to obtain both accurate T1 and T2 maps.In conclusion, through the implementation of a self-gating module, a spiral Cartesian encoding and a Compressed-Sensing acceleration, the new DESS sequence allows a rapid and repeatable estimation of T2 in the whole brain in 3D at multiple magnetic fields.Further improvements are needed to improve the T2 accuracy, and to simultaneously measure multiple quantitative parameters though the application of one sequence

Testo completoAbstract : At rest, healthy human brain activity is characterized by large electroencephalography (EEG) fluctuations in the 8-13 Hz range, commonly referred to as the alpha band. Although it is well known that EEG alpha activity varies across individuals, few studies have investigated how this may be related to underlying morphological variations in brain structure. Specifically, it is generally believed that the lateral geniculate nucleus (LGN) and its efferent fibres (optic radiation, OR) play a key role in alpha activity, yet it is unclear whether their shape or size variations contribute to its inter-subject variability. Given the widespread use of EEG alpha in basic and clinical research, addressing this is important, though difficult given the problems associated with reliably segmenting the LGN and OR. For this, we employed a multi-modal approach and combined diffusion magnetic resonance imaging (dMRI), functional magnetic resonance imaging (fMRI) and EEG in 20 healthy subjects to measure structure and function, respectively. For the former, we developed a new, semi-automated approach for segmenting the OR and LGN, from which we extracted several structural metrics such as volume, position and diffusivity. Although these measures corresponded well with known morphology based on previous post-mortem studies, we nonetheless found that their inter-subject variability was not significantly correlated to alpha power or peak frequency (p > 0.05). Our results therefore suggest that alpha variability may be mediated by an alternative structural source and our proposed methodology may in general help in better understanding the influence of anatomy on function.
