Stability metrics for optic radiation tractography: Towards damage prediction after resective surgery
BACKGROUND An accurate delineation of the optic radiation (OR) using diffusion MR tractography may reduce the risk of a visual field deficit after temporal lobe resection. However, tractography is prone to generate spurious streamlines, which deviate strongly from neighboring streamlines and hinder a reliable distance measurement between the temporal pole and the Meyer's loop (ML-TP distance). ...
متن کاملStrengths and limitations of tractography methods to identify the optic radiation for epilepsy surgery.
Diffusion tensor imaging (DTI) tractography (TG) can visualize Meyer's loop (ML), providing important information for the epilepsy surgery team, both for preoperative counseling and to reduce the frequency of visual field defects after temporal lobe resection (TLR). This review highlights significant steps in the TG process, specifically the processing of raw data including choice of TG algorit...
متن کاملImproved Framework for Tractography Reconstruction of the Optic Radiation
The optic radiation (OR) is one of the major components of the visual system and a key structure at risk in white matter diseases such as multiple sclerosis (MS). However, it is challenging to perform track reconstruction of the OR using diffusion MRI due to a sharp change of direction in the Meyer's loop and the presence of kissing and crossing fibers along the pathway. As such, we aimed to pr...
متن کاملReoperation after failed resective epilepsy surgery
PURPOSE Resection of the seizure focus leads to sustained seizure-freedom in intractable focal epilepsy in up to 80% of selected populations. However, surgery fails to help in a considerable proportion of patients. Reevaluation and reoperation may be considered in a selected group of patients with an unfavorable postsurgical outcome. Here, we reviewed 15 case series on reoperation after failed ...
متن کاملTransient aphasias after left hemisphere resective surgery.
OBJECT Transient aphasias are often observed in the first few days after a patient has undergone resection in the language-dominant hemisphere. The aims of this prospective study were to characterize the incidence and nature of these aphasias and to determine whether there are relationships between location of the surgical site and deficits in specific language domains. METHODS One hundred te...
