The utility of preoperative diffusion tensor imaging in the surgical management of brainstem cavernous malformations.

Object: Resection of brainstem cavernous malformations (BSCMs) may reduce the risk of stepwise neurological deterioration secondary to hemorrhage, but the morbidity of surgery remains high. Diffusion tensor imaging (DTI) and diffusion tensor tractography (DTT) are neuroimaging techniques that may assist in the complex surgical planning necessary for these lesions. The authors evaluate the utility of preoperative DTI and DTT in the surgical management of BSCMs and their correlation with functional outcome.

Automated quantification of white matter disease extent at 3 T: comparison with volumetric readings.

Purpose: To develop and validate an algorithm to automatically quantify white matter hyperintensity (WMH) volume.

Materials And Methods: Images acquired as part of the Dallas Heart Study, a multiethnic, population-based study of cardiovascular health, were used to develop and validate the algorithm. 3D magnetization prepared rapid acquisition gradient echo (MP-RAGE) and 2D fluid-attenuated inversion recovery (FLAIR) images were acquired from 2082 participants.

Computed tomography in the diagnosis of occult open-globe injuries.

Purpose: To determine the radiographic signs present on computed tomography (CT) most suggestive of occult open-globe injury.

Design: Retrospective chart review.

Participants: Forty-eight eyes (of 46 patients), 34 of which were found to have an occult open-globe injury on surgical exploration.
