ABSTRACT
Objective To evaluate the functional features of motor function area in patients with meningioma by blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI).Methods fMRI were obtained from 10 patients who suffered from meningioma which was adjacent to the motor function cortex.Probabilistic independent component analysis method was used for data analysis.Preoperative and postoperative line Karnofsky Performance Scale (KPS)score was used to assess the patient’s condition.Re-sults Contralateral primary motor cortex and the supplementary motor cortex motor functions were observed in all the activation clusters,in which one side activation area compared with the contralateral activation zone was symmetrical in 6 cases,and significant shift in 4 cases.In 4 patients with the movement function activated,tumor extrusion function shift forward or backwardwith tensile deforma-tion were found.Conclusion BOLD-fMRI imaging technology can effectively locate motor functional area for patients with meningi-oma,which can provide preoperative surgical planning.
ABSTRACT
Objective To study the incidence and clinical significance of the herniation pits of the femoral neck.Methods 600 cases(299 men,301 women,18～82 years)were collected.The incidence,radiologic finding and clinical significance of the herniation pit of the femoral neck were analysed.Results Of 1200 hip joints in 600 cases,there was 58 cases(64 sides)(5.3%)with herniation pits of the femoral neck,including 39 men(68.7%)and 19 women(31.3%),the lesions localized in the left joint in 25 eases(39.1%),in the right joint in 27 cases(42.2%)and in bilateral joints in 6 cases(18.7%).There were a obvious significant differences on both sexes,and no significant differences on age groups.On X-ray film,the lesions appeared as a round radiolucency with thin clear sclerotic rim.Conclusion The incidence of the herniation pit of the femoral neck is 5.3%,which has a typical X-ray feature,and may indicate the femoroacetabular impingement.
