Background: Direct carotid-cavernous fistulas (dCCFs) are often treated endovascularly. However, because the dCCF is usually a high-flow shunt, it is often difficult to obtain an accurate vascular structure using conventional digital subtraction angiography (DSA). Here, the authors report a case of successfully treated dCCF using three-dimensional (3D) fused DSA images.
Observations: The patient presented with tinnitus, followed by oculomotor palsy, prompting magnetic resonance imaging that indicated a dural arteriovenous fistula of the cavernous sinus. DSA was performed before treatment, and a diagnosis of dCCF due to a ruptured aneurysm was made. In this case, the 3D fused simulation images enabled the authors to obtain an accurate vascular structure, resulting in successful coil embolization.
Lessons: Three-dimensional fusion images from DSA provide detailed anatomical information and are useful for treating high-flow dCCFs.

Purpose We aimed to compare postoperative changes in intervertebral foraminal areas and the mechanisms of foraminal stenosis following fixation surgery for cervical spondylotic myelopathy (CSM) with local kyphosis and instability, using three-dimensional computed tomography (3DCT). Methods We retrospectively analyzed 55 patients who underwent posterior cervical spinal fixation using pedicle screws. A total of 71 spinal levels (C2/3 to C7/T1) and 144 intervertebral foramina with anchor screws inserted in the upper and lower vertebrae were examined.

Cellulose nanocrystals (CNCs) have emerged as promising candidates for chiroptical functional materials due to their ability to form cholesteric liquid crystals with tunable periodicity. The quality of the final cholesteric phase is influenced by the nucleation, growth and coalescence mechanism of the initial droplets, known as tactoids. Current research focuses on understanding the size and morphological transformations of these tactoids, to gain deeper insights into their dynamic behavior and, in turn, to better control the final properties of novel photonic materials.

Background: Three-dimensional (3D) modeling has been used in the management of bony head and neck tumors, but not in soft tissue tumors. Currently, histopathological findings of oral squamous cell carcinomas (OSCC) are presented as two-dimensional images. Previously, we developed a 3D image fusion method that presents tumor histopathology and MRI in 3D form.

Multi-modal data fusion plays a critical role in enhancing the accuracy and robustness of perception systems for autonomous driving, especially for the detection of small objects. However, small object detection remains particularly challenging due to sparse LiDAR points and low-resolution image features, which often lead to missed or imprecise detections. Currently, many methods process LiDAR point clouds and visible-light camera images separately, and then fuse them in the detection head.

Purpose: In patients presenting with the sandwich fusion, characterized by C1 occipitalization and C2-C3 non-segmentation, leading to stress concentration at the atlantoaxial joint, there is an increased likelihood of atlantoaxial dislocation (AAD). The decision to proceed with transoral surgery is contingent upon the outcomes of intraoperative traction assessment. The complexity of intraoperative decision-making introduces a degree of uncertainty in preoperative planning, complicating both the surgical preparation and doctor-patient communication.
