Whereas fMRI postprocessing tools used in research are accurate but unwieldy, those used for clinical practice are user-friendly but are less accurate. We aimed to determine whether commercial software for fMRI postprocessing is accurate enough for clinical practice.
Ten volunteers underwent fMRI while performing motor and language tasks (hand, foot, and orolingual movements; verbal fluency; semantic judgment; and oral comprehension). We compared visual concordance, image quality (noise), voxel size, and radiologist preference for the activation maps obtained by using Neuro3D software (provided with our MR imaging scanner) and by using the SPM program commonly used in research.
Maps obtained with the 2 methods were classified as "partially overlapping" for 70% for motor and 72% for language paradigm experiments and as "overlapping" in 30% of motor and in 15% of language paradigm experiments.
fMRI is a helpful and robust tool in clinical practice for planning neurosurgery. Widely available commercial fMRI software can provide reliable information for therapeutic management, so sophisticated, less widely available software is unnecessary in most cases.
虽然研究中使用的 fMRI 后处理工具准确但难以操作，而用于临床实践的工具则易于使用但准确性较低。我们旨在确定用于 fMRI 后处理的商业软件是否足够准确，可用于临床实践。
10 名志愿者在手、脚和口部运动（手部、脚部和口部运动；言语流畅性；语义判断；口头理解）任务中接受 fMRI 检查。我们比较了使用 Neuro3D 软件（随我们的磁共振成像扫描仪提供）和研究中常用的 SPM 程序获得的激活图的视觉一致性、图像质量（噪声）、体素大小以及放射科医生的偏好。
对于运动和语言范式实验，两种方法获得的图谱分别有 70%和 72%被归类为“部分重叠”，有 30%和 15%被归类为“重叠”。
fMRI 是临床实践中神经外科计划的有用且强大的工具。广泛可用的商业 fMRI 软件可为治疗管理提供可靠的信息，因此在大多数情况下不需要复杂但使用范围不广的软件。
