PURPOSE To determine whether a hyperintense layer adjacent to the lateral ventricle on T2-weighted MR images represents the optic radiation. METHODS We reviewed 11 brain specimens from patients with nonneurologic diseases and MR images from 43 healthy volunteers. The MR images in a patient with cerebral infarction involving the lateral geniculate body were also reviewed to evaluate wallerian ...

UNLABELLED Numerous fibrous elements known as the Willis chords are situated in the light of the superior sagittal sinus. The paper is aimed at a comparative evaluation of the appearance of the Willis chords appearing in the superior sagittal sinus during various periods of human life and a determination of their role. The material comprises 200 brains at the foetal period as well as 200 adult ...

Spinal deformities can result in increasing thoracic kyphosis or loss of lumbar lordosis, leading to imbalance in the sagittal plane. Such deformities can be functionally and psychologically debilitating. The Smith-Petersen osteotomy can achieve approximately 10 degrees of correction in the sagittal plane at each spinal level at which it is performed. This osteotomy is beneficial for patients w...

OBJECTIVE To investigate the relationship between bone mineral density (BMD) and sagittal spinal balance in the Korean elderly population. METHODS The retrospective study included subjects aged 60 years and above, who had whole-spine lateral radiography and dual-energy X-ray absorptiometry (DEXA) within a year's gap between each other. Sagittal vertical axis (SVA) for evaluation of sagittal s...

PURPOSE To compare prostate contours on conventional stepping transverse image acquisitions with those on twister-based sagittal image acquisitions. MATERIAL AND METHODS Twenty prostate cancer patients who were planned to have permanent interstitial prostate brachytherapy were prospectively accrued. A transrectal ultrasonography probe was inserted, with the patient in lithotomy position. Tran...

Skeletal relationships in the sagittal plane do not always correspond with dental relationships. The aim of this study was to determine in which type of malocclusion the correlation between overjet and skeletal sagittal parameters assessed by lateral cephalogram analysis is the highest. The extent to which overjet can predict skeletal relationships in the sagittal plane was also assessed. Eight...

PURPOSE This study aimed to assess the efficacy of 3D surface-rendered (SR) magnetic resonance (MR) images for surgical planning of uterine fibroids. METHODS Ten patients with uterine fibroids underwent 3D volume isotropic turbo spin-echo acquisition (VISTA) sequences in sagittal planes. SR images showing the uterine body, endometrium, and fibroids were extracted from the raw MR data. The pre...

STUDY DESIGN Retrospective study. PURPOSE To investigate influence of bone mineral density (BMD) on the surgical correction of lumbar degenerative kyphosis (LDK). OVERVIEW OF LITERATURE No studies so far have reported the influence of BMD on the surgical correction of LDK. METHODS Forty LDK patients with more than 2 years follow-up were studied. Pelvic incidence (PI), pelvic tilt, sacral ...

This paper introduces a walking pattern generation method on an inclined terrain in both pitch and roll directions, and uneven terrain. The walking pattern generation method is based on a modifiable walking pattern generator (MWPG) which allows a zero moment point (ZMP) variation in real-time. As a navigational command set, a 3-D command state (CS) is defined, which consists of single and doubl...
