摘要

研究目的本研究评估了使用无声和飞行时间(TOF)磁共振血管造影(MRA)和计算机断层扫描(CT)的多模态图像融合(MIF)对有造影剂禁忌症的颅内动脉瘤患者进行术前规划的有效性:这项回顾性研究纳入了 40 名使用三维计算机断层扫描血管造影术(CTA)确诊的颅内动脉瘤患者。这些患者都接受了静态和 TOF MRA 扫描,然后进行了 CTA 扫描。使用 3DSlicer 软件的多图像融合(MIF)技术将无声/TOF MRA 与 CT 图像整合在一起进行术前评估。这项研究比较了 MIF 图像与三维 CTA 图像的图像质量、动脉瘤检测灵敏度和解剖准确性:结果:与 TOF-MRA-CT 相比,无声-MRA-CT 融合图像显示出更高的灵敏度(95.5%)和更低的假阴性率(4.5%)。此外,无声-MRA-CT 融合图像在信号均匀性、静脉信号干扰抑制和动脉瘤可见度方面均优于 TOF-MRA-CT(所有 P <0.05)。动脉瘤形态和形状的类间相关系数和卡帕值表明,无声-MRA-CT 与 CTA 的测量一致性和形状一致性优于 TOF-MRA-CT(所有 P < 0.01):本研究支持将无声/TOF-MRA-CT 融合成像作为 CTA 的可靠替代方法,并指出无声-MRA-CT 与 CTA 非常相似。对于有造影剂禁忌症的颅内动脉瘤患者,无对比剂的 MRA-CT 融合成像有望用于术前规划。

Enhanced Preoperative Planning for Intracranial Aneurysms Through Multimodal Image Fusion of Silent/Time-of-Magnetic Resonance Angiography and Computed Tomography Using 3DSlicer: A Comparative Efficacy Analysis With Computed Tomography Angiography.

Objective: This study evaluates the effectiveness of multimodal image fusion (MIF) using silent and time-of-flight (TOF) magnetic resonance angiography (MRA) and computed tomography (CT) for preoperative planning in patients with intracranial aneurysms who have contraindications to contrast media.

Materials and methods: A retrospective study included 40 patients with intracranial aneurysms, diagnosed using three-dimensional computed tomography angiography (CTA). These patients underwent both Silent and TOF MRA scans, followed by a CTA scan. The multi-image fusion (MIF) technique, applied using 3DSlicer software, integrated the silent/TOF-MRA with CT images for preoperative assessment. This study compared the image quality, aneurysm detection sensitivity, and anatomic accuracy of the MIF images with those of three-dimensional CTA.

Results: Silent-MRA-CT fusion images demonstrated higher sensitivity (95.5%) and lower false negative rates (4.5%) compared with TOF-MRA-CT. Furthermore, silent-MRA-CT fusion images outperformed TOF-MRA-CT in terms of signal homogeneity, venous signal interference suppression, and aneurysm visibility (all P < 0.05). The interclass correlation coefficient and kappa values for aneurysm morphology and shape indicated superior measurement consistency and shape concordance of silent-MRA-CT with CTA compared with TOF-MRA-CT (all P < 0.01).

Conclusion: This study supports the use of silent/TOF-MRA-CT fusion imaging as a reliable alternative to CTA, noting that silent-MRA-CT closely mirrors CTA. Contrast-free MRA-CT fusion images have the potential to be used for preoperative planning in patients with intracranial aneurysms who have contraindications to contrast.
