【摘要】： 距狀溝是枕葉內(nèi)側(cè)面較為重要和恒定的腦溝,是臨床疾病診斷、手術(shù)治療及功能研究的界標(biāo)性結(jié)構(gòu)。但對距狀溝形態(tài)、大小、側(cè)差及性差的活體影像學(xué)研究資料較為缺乏。本研究對60例(男30,女30)健康青年志愿者的頭部MRI圖像進(jìn)行三維重建后,觀察距狀溝后部在正中矢狀面上的形態(tài)、位置,并分析其左右側(cè)差和男女性差別。同時研究了枕葉副腦室的出現(xiàn)率。用Brainvisa軟件對獲取的MR圖像進(jìn)行三維重建后,軟件自動測量距狀溝的溝深、溝寬和溝長。用SPSS軟件對結(jié)果進(jìn)行統(tǒng)計分析,比較左右側(cè)的差別及男女性的差別。本研究對活體的MRI圖像進(jìn)行三維重建后研究距狀溝的形態(tài)、大小及側(cè)差和性差,為枕葉病變診斷、枕葉手術(shù)及視覺皮質(zhì)功能影像學(xué)研究提供解剖學(xué)基礎(chǔ)。本實(shí)驗分為三個部分,摘要如下： 第一部分國人女性距狀溝形態(tài)、大小及側(cè)差的NRI研究 目的：歸納國人女性距狀溝在MR圖像的正常形態(tài),提供其大小的正常值范圍,并研究其左右側(cè)的差別,為臨床診斷、手術(shù)治療和功能研究提供解剖學(xué)基礎(chǔ)。 方法：對30例女性志愿者頭部進(jìn)行高分辨率MRI掃描,獲取橫斷面圖像,用Brainvisa軟件對其三維重建后,觀察距狀溝在正中矢狀面上的形態(tài)和位置,軟件自動測量距狀溝的溝深、溝寬和溝長。用SPSS軟件對結(jié)果進(jìn)行統(tǒng)計分析,比較左右側(cè)的差別。 結(jié)果：在正中矢狀面上距狀溝后部分為分叉型(43.33%)和不分叉型(56.67%)。不分叉型又分為五種亞型：單峰型(16.67%)、平坦型(15.00%)、S型(10.00%)、雙峰型(8.33%)和其他型(6.67%)。距狀溝后部在正中矢狀面上的位置可分為偏下(61.67%)、中間(30.00%)、偏上(8.33%)三種情況。枕葉副腦室的出現(xiàn)率為38.33%。原始數(shù)據(jù)組女性距狀溝溝深右側(cè)明顯大于左側(cè)(P＜0.001),溝寬和溝長差別無統(tǒng)計學(xué)意義。標(biāo)準(zhǔn)化處理組其相關(guān)參數(shù)未見有明顯的左右側(cè)差別。距狀溝末端超過半數(shù)(56.67%)轉(zhuǎn)到大腦半球的外側(cè)面或底面。 結(jié)論：女性距狀溝的溝深右側(cè)明顯大于左側(cè)。三維重建的研究方法在研究結(jié)構(gòu)復(fù)雜的距狀溝的形態(tài)和參數(shù)方面有一定的優(yōu)勢。 第二部分國人男性距狀溝的形態(tài)、大小及側(cè)差MRI研究 目的：歸納國人男性距狀溝在MR圖像的正常形態(tài),提供其大小的正常值范圍,并研究其左右側(cè)差別,為臨床診斷、手術(shù)治療和功能研究提供解剖學(xué)基礎(chǔ)。 方法：對30例男性志愿者頭部進(jìn)行高分辨率MRI掃描,獲取橫斷面圖像,用Brainvisa軟件對其三維重建后,觀察距狀溝在正中矢狀面上的形態(tài)和位置,軟件自動測量距狀溝的溝深、溝寬和溝長。用SPSS軟件對結(jié)果進(jìn)行統(tǒng)計分析,比較左右側(cè)的差別。 結(jié)果：在正中矢狀面上距狀溝后部分為分叉型(46.67%)和不分叉型(53.33%)。不分叉型又分為五種亞型：單峰型(11.67%)、平坦型(16.67%)、S型(10.00%)、雙峰型(10.00%)和其它型(5.00%)六種類型。距狀溝后部在正中矢狀面上的位置可分為偏下(70.00%)、中間(21.67%)、偏上(8.33%)三種情況。原始數(shù)據(jù)組及標(biāo)準(zhǔn)化處理組男性距狀溝的溝底長、溝頂長、溝深和溝寬均未見明顯的左右側(cè)差別。距狀溝末端超過半數(shù)(53.33%)轉(zhuǎn)到大腦半球的外側(cè)面。枕葉副腦室的出現(xiàn)率為36.67%。 結(jié)論：男性距狀溝的溝底長、溝頂長、溝深和溝寬均未見明顯的左右側(cè)差別。三維重建的研究方法在研究結(jié)構(gòu)復(fù)雜的距狀溝的形態(tài)和參數(shù)方面有一定的優(yōu)勢。 第三部分國人距狀溝形態(tài)及大小的男女差別 目的：研究國人距狀溝形態(tài)及大小的男女性差,為相應(yīng)的功能研究及臨床疾病研究提供解剖學(xué)基礎(chǔ)。 方法：對30例男性、30例女性志愿者頭部進(jìn)行高分辨率MRI掃描,獲取橫斷面圖像,用Brainvisa軟件對其三維重建后,觀察距狀溝在正中矢狀面上的形態(tài)和位置,軟件自動測量距狀溝的溝深、溝寬和溝長。用SPSS軟件對結(jié)果進(jìn)行統(tǒng)計分析,比較男女性差別。 結(jié)果：距狀溝各形態(tài)、位置分型均未見顯著的男女性差別。未標(biāo)化的原始數(shù)據(jù)顯示男性距狀溝的溝長、溝寬和溝深均稍大于女性,只有左側(cè)溝深的差別具有統(tǒng)計學(xué)意義,男性明顯大于女性(t=3.06,P=0.003)。數(shù)據(jù)標(biāo)準(zhǔn)化后,距狀溝的相關(guān)參數(shù)均未見顯著的性差。 結(jié)論：原始數(shù)據(jù)組測得左側(cè)溝深男性明顯大于女性,標(biāo)準(zhǔn)化處理后此差別消失,男女性顱的大小可能是影響其距狀溝大小差別的主要因素。 結(jié)論和意義 本研究對MRI圖像進(jìn)行三維重建后研究了距狀溝的大小、形態(tài)以及側(cè)差和性差的影響,為該區(qū)臨床疾病診斷準(zhǔn)確定位到腦溝水平、手術(shù)治療中準(zhǔn)確尋找病灶及視覺皮質(zhì)功能研究提供解剖學(xué)基礎(chǔ)和指導(dǎo)。與標(biāo)本研究相比,本活體研究可能對臨床更有指導(dǎo)意義。但是由于本研究志愿者的年齡范圍較窄,未得到距狀溝的形態(tài)特征等隨年齡的變化。而且,距狀溝的不同形態(tài)和大小是否與視覺功能之間有聯(lián)系,也有待于進(jìn)一步的研究。
[Abstract]:The calcarine sulcus is the medial occipital lobe is more important and constant, is the clinical diagnosis, treatment and functional structure of the landmark operation. But the calcarine sulcus morphology, size, poor and poor side in vivo imaging studies are lack of. This study of 60 patients (male 30, female 30) head MRI images of healthy young volunteers were reconstructed after the observation of calcarine sulcus posterior in the median sagittal plane shape, position, and analyze the difference and the difference between left and right side of men and women. At the same time on the emergence of the accessory occipital ventricle rate. 3D reconstruction of MR images with Brainvisa software software, the automatic measurement of calcarine sulcus depth, gully width and length. The results were analyzed by SPSS software. The difference between left and right side and the gap between the sexes. The calcarine sulcus forms the study MRI image in vivo three-dimensional reconstruction, the size and lateral difference and difference This study provides the anatomical basis for the diagnosis of occipital lobe lesions, occipital lobe surgery and visual cortex functional imaging. This experiment is divided into three parts, which are as follows:
The NRI study of the shape, size and side difference of female ditches in the first part of Chinese women
Objective: To summarize the normal morphology of Chinese female ditches in MR images, provide the normal range of their size, and study the difference between the left and right sides, so as to provide anatomical basis for clinical diagnosis, surgical treatment and functional research.
Methods: high resolution MRI scan in 30 cases of female volunteers head, obtain cross-sectional images, using Brainvisa software for the 3D reconstruction, observe the morphology and position of the calcarine sulcus in the sagittal plane, the software of automatic measurement of calcarine sulcus depth, gully width and length. The results were analyzed by SPSS software, comparison of left and right side of the difference.
Results: the calcarine sulcus on sagittal plane on the rear part is a bifurcation type (43.33%) and (56.67%). This type of bifurcation type is divided into five subtypes: single peak type (16.67%), flat type (15%), S (10%), Shuangfeng (8.33%) and other type. (6.67%). In the middle of the calcarine sulcus posterior sagittal position can be divided into lower (61.67%), middle (30%), partial (8.33%) three cases. Occipital ventricle vice rate of 38.33%. original data group of female calcarine sulcus was significantly larger than the left on the right side of the trench depth (P < 0.001), gully width and length of the difference was not statistically significant. The standardized treatment of left and right side group showed no obvious difference from the relevant parameters. More than half of groove end (56.67%) to the outer side of the cerebral hemisphere or the bottom surface.
Conclusion: the right side of the grooves is larger than the left side of the female grooves. The method of three-dimensional reconstruction has certain advantages in studying the morphology and parameters of the complex structures.
MRI study on the shape, size and side difference of the second parts of Chinese male ditches
Objective: To summarize the normal morphology of male male ditches in MR images, provide the normal range of their size, and study the difference between the left and right sides, so as to provide anatomical basis for clinical diagnosis, surgical treatment and functional research.
Methods: high resolution MRI scan in 30 cases of male volunteers head, obtain cross-sectional images, using Brainvisa software for the 3D reconstruction, observe the morphology and position of the calcarine sulcus in the sagittal plane, the software of automatic measurement of calcarine sulcus depth, gully width and length. The results were analyzed by SPSS software, comparison of left and right side of the difference.
Results: the calcarine sulcus on sagittal plane on the rear part is a bifurcation type (46.67%) and (53.33%). This type of bifurcation type is divided into five subtypes: single peak type (11.67%), flat type (16.67%), S (10%), Shuangfeng (10%) and other type (5%) six types. In the calcarine sulcus posterior median sagittal position can be divided into lower (70%), middle (21.67%), partial (8.33%) three cases. The original data standardization group and treatment group male calcarine sulcus of the bottom, top long ditch, ditch deep and wide ditch showed no obvious difference from the left and right sides. More than half of the end groove (53.33%) to the outer side of the cerebral hemisphere. The occipital side ventricle rate is 36.67%.
Conclusion: there is no obvious difference between the left and right sides of the furrow base, the length of the furrow, the depth of the furrow and the width of the furrow. The method of three-dimensional reconstruction has certain advantages in studying the morphology and parameters of the complex trapdoor sulcus.
The difference between the shape and size of the third parts of the national human distance trench
Objective: To study the difference in the morphology and size of human distance trench, and to provide the anatomical basis for the study of the corresponding function and the study of clinical diseases.
Methods: 30 cases of male, high resolution MRI scan was performed in 30 cases of female volunteers head, obtain cross-sectional images, using Brainvisa software for the 3D reconstruction, observe the morphology and position of the calcarine sulcus in the sagittal plane, the software of automatic measurement of calcarine sulcus depth, gully width and length of the statistical analysis. The results were compared with SPSS software, and the difference.
Results: the morphology of the calcarine sulcus, the location type of men and women. There were no significant differences of unlabeled raw data showed that male calcarine sulcus length, gully width and depth are slightly larger than females, with statistical significance only on the left side ditch deep differences, males were significantly larger than females (t=3.06, P=0.003). After data standardization, the relevant parameters of the calcarine sulcus showed no significant difference.
Conclusion: in the original data set, the left groin depth was significantly larger in males than in females. After normalization treatment, the difference disappeared. The size of male and female cranium may be the main factor affecting the size difference between them.
Conclusion and significance
The study on 3D reconstruction of MRI images of the calcarine sulcus size, shape and side effects of poor and poor, for the clinical diagnosis of disease accurately locate the cerebral sulci level, surgical treatment of lesions and accurately find visual cortical function and provide anatomical basis and guidance. This study compared with specimens. In vivo study on clinical significance. But more because the volunteers age range is narrow, not of the calcarine sulcus morphology changes with age. Moreover, calcarine sulcus of different shape and size and whether there is a link between the visual function, but also need to be further studied.
