The efficacy of transforaminal epidural steroid injections in lumbosacral radiculopathy.

Background: Transformational epidural steroid (TFES) is commonly used to treat lumbosacral radicular pain. However, very few studies have systematically evaluated the quality of analgesia following such procedures with respect to time.

Objective: To evaluate long-term efficacy of TFES in patients with lumbosacral radiculopathy.

Can diffusion tensor metrics help in preoperative grading of diffusely infiltrating astrocytomas? A retrospective study of 36 cases.

Introduction: Diffusion weighted imaging and diffusion tensor imaging (DTI) give information about the amount and directionality of water diffusion occurring in a given tissue. Here we study the role of diffusion tensor metrics including fractional anisotropy (FA) and spherical anisotropy (CS) in preoperative grading of diffusely infiltrating astrocytomas.

Methods: We performed DTI in 38 patients with pathologically proven diffusely infiltrating astrocytomas, who were classified into two groups, i.

Diffusion tensor mode in imaging of intracranial epidermoid cysts: one step ahead of fractional anisotropy.

Introduction: The signal characteristics of an epidermoid on T2-weighted imaging have been attributed to the presence of increased water content within the tumor. In this study, we explore the utility of diffusion tensor imaging (DTI) and diffusion tensor metrics (DTM) in knowing the microstructural anatomy of epidermoid cysts.

Materials And Methods: DTI was performed in ten patients with epidermoid cysts.
