Abstract

Purpose: The aim was to establish a functional MRI protocol for analyzing human stereoscopic vision in clinical practice. The feasibility was established in a cohort of 9 healthy subjects to determine the functional cortical areas responsible for virtually relief vision.

Methods: Nine healthy right-handed subjects underwent orthoptic examination and functional MRI. The activation paradigms used were based on a block sequence with the projection of static and dynamic 2D and 3D test patterns during three experiments. The test patterns were projected through two separate eyepieces to create stereoscopic vision. SPM software was used for post-processing and data analysis.

Results: Among the three different test patterns used, the second, which corresponded to a static high-relief image of a billiard, appeared to be significant for identifying cortical area activation during stereoscopy. In the group analysis, only areas V3A and V6 showed statistically significant activation. Individual analysis revealed activation of the rostral IPS and V5/MT+.

Conclusion: More data is needed to determine the precise cortical area of activation for stereoscopy. This study proposes a useful and accessible method for functional MRI analysis of stereoscopy.

用于立体视觉分析的功能性MRI：一个实验设计。

目的：在临床实践中建立一种分析人体立体视觉的功能性MRI方案。在9名健康受试者的队列中确定负责虚拟救济视力的皮质功能区域的可行性。方法：对9名健康右撇子进行正视检查和功能MRI检查。在三个实验中，使用的激活范式是基于静态和动态二维和三维测试模式投影的块序列。测试图案通过两个独立的目镜投射，以创造立体视觉。采用SPM软件进行后处理和数据分析。结果：在使用的三种不同的测试模式中，第二种测试模式对应于一个静态的高浮雕台球图像，似乎对识别立体视觉期间皮层区域的激活具有重要意义。在分组分析中，只有V3A和V6区域显示有统计学意义的激活。个体分析显示吻侧IPS和V5/MT+激活。结论：需要更多的数据来精确确定立体视觉的皮层激活区域。本研究提出了一种实用且容易获得的立体功能MRI分析方法。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
