In our study, MR angiography was a sensitive and very specific method to access the stability of an incomplete occlusion or to diagnose recanalization of the intracranial aneurysm. The use of gadolinium did not improve the ability of 3D time of flight MR angiography to detect the presence of residual or recurrent aneurysm. In one giant aneurysm, the use of intravenous medium contrast did result in improved visualization of a residual aneurysm. With the parameters used, first-pass dynamic contrast-enhanced MR angiography images had a good resolution but its spatial resolution were lower than those on enhanced 3D time of flight MR angiography images performed in the steady state. MR angiography results was better than the analyse of the coil-ball appearance on plain radiographic to predict the instability of angiographic occlusion. The artifact due to the use of a GDC Trispan coil has been confirmed by an in vitro study

Intracranial aneurysms are local dilatations of cerebral blood vessels, presenting a significant risk of rupture, which can lead to serious consequences. Early detection of unruptured aneurysms is therefore crucial to prevent potentially fatal complications. However, analyzing medical images to locate these aneurysms is a complex and time-consuming task, requiring time and expertise, and yet remains prone to errors in interpretation. Faced with these challenges, this thesis explores automated methods for the detection of aneurysms, aiming to facilitate the work of radiologists and improve diagnostic efficiency. Our approach focuses on the use of artificial intelligence techniques, particularly deep neural networks, for the detection of aneurysms from time-of-flight magnetic resonance angiography (TOF-MRA) images. Our research work is centered around several main axes. Firstly, due to the scarcity of training data in the medical field, we adopt a rapid, although approximate, annotation method to facilitate data collection. Furthermore, we propose a strategy based on small patches. In association with data synthesis, the samples are multiplied in the training database. By selecting the samples, their distribution is adjusted to facilitate optimization. Secondly, for the automated detection of aneurysms, we investigate various neural network architectures. An initial approach explores image segmentation networks. Then, we propose an innovative architecture inspired by object detection methods. These architectures, especially the latter, lead to competitive results, particularly in terms of sensitivity compared to experts. Thirdly, beyond the detection of aneurysms, we extend our model to estimate the pose of aneurysms in 3D images. This can greatly facilitate their analysis and interpretation in reformatted cross-sectional plans. A thorough evaluation of the proposed models is systematically carried out, including ablation studies, the use of metrics adapted to the problem of detection, and evaluations conducted by clinical experts, allowing us to assess their potential effectiveness for clinical use. In particular, we highlight the issues related to uncertainty in the annotation of existing databases

Intracranial aneurysms are a hazard to human health because of their high rupture rate and fatal subsequence, such as subarachnoid hemorrhage. In order to carry out a hemodynamic research in vitro on the intracranial aneurysm, a phantom is indispensable. Until now, rigid or simplified phantoms are mainly used in the literature, few among them possess sufficient properties compared with reality. The work of this thesis focuses on the methodology of manufacturing patient-specific phantoms of intracranial aneurysms as well as their implementation for different uses. The phantoms have an anatomical shape of patient’s artery and an elastic wall. They are manufactured by applying an original rapid prototyping technique. The phantoms are examined and verified in different ways. In order to perform a hemodynamic research of the phantoms, a testing platform compatible with different imaging modalities has been designed and established. 2D phase-contrast magnetic resonance angiography was applied in the hemodynamic study of the phantoms. The dynamic behavior of the artery wall, the 3D path-line of flow and the velocity field of flow were analyzed. The potential application in the clinical domain of the patient-specific phantoms was also tested in this thesis, simulations of intervention on intracranial aneurysms were carried out with the testing platform and the phantoms, the results of different treatment strategies were analyzed and compared

Since 1991 and the introduction of detachable intracranial coils, the endovasculary treatment of cerebral aneurysms has become an established treatment technique and has supplied surgical approach of these aneurysms. The rate of morbidity and mortality of this new technique is now well known and law. Initial Angiographic and clinical results were yet published with good outcome. Concern exists about long term reopening and the inherent risk of recurrent hemorrhage and long-term imaging follow-up is advocated. Digital Substract Hemorrhage was the gold standard for detection and follow-up of patients, but this diagnostic procedure is invasive and exposes the patient to a small risk of serious complication. MR angiography has been used as an alternative noninvasive imaging technique to assess the occlusion of coiled intracranial aneurysms with promising results. Since 1998, we have collected all patients with subarachnoid hemorrhage, and patients with cerebral aneurysms treated by endovascular approach. We have proposed different MRI sequences to valid this technique and improve this techniqueWe have compared 3D TOF to digital angiography, with sequences with injection of gadolinium. [...]

Background: to fill an aneurysm with detachable platinum coils as much as possible ensure protection against further aneurysm recurrence. As a start, silicone sidewall aneurysm models were filled with various types of coils using conventional endovascular technique. Higher packing ratios (volume of inserted coils / volume of the aneurysm) were obtained with “Soft” coils when compared with “Standard” coils. As well, “Complex-shaped” coils provided with higher packing ratios than did “Helicoidal” coils. Moreover, 3D angiography was found to be more accurate than CT and MR angiographies in the determination of the aneurysm volume. Secondly, in the clinical setting, we used 3D angiography in 255 aneurysm volume measurements and calculation of packing ratios. High aneurysm packing ratios were not found to protect against aneurysm recurrence. Conversely, the aneurysm volume and the duration of angiographic follow-up were found to be statistically determinant factors of aneurysm recurrence
