Interleaved spiral scanning of k-space is an efficient and fast method for imaging dynamic processes. In this article, a cine version of interleaved spiral imaging is presented. The method is shown to overcome the "lightning-flash" artifacts of the conventional triggered (gated) method. Compared with the segmented k-space 2DFT method, it achieves better temporal resolution in a comparable or shorter scan time. Preliminary human studies show that the method is a promising tool for imaging dynamic processes.

BackgroundPercutaneous vertebroplasty (PVP) is the mainstream treatment for osteoporotic vertebral compression fractures (OVCF). In order to provide better clinical efficacy and reduce complications, various bone cement applicators are still being developed and gradually applied in clinical practice. However their clinical results are still to be reported.

Hypothesis: This study investigates how electrode array types-straight versus perimodiolar-affect cochlear implant (CI) placement (i.e., modiolar proximity and angular depth) and outcomes using cone beam computed tomography (CBCT) and evoked electrical auditory brainstem responses (eABR).

Obtaining clear images is of great help in determining the type and etiology of AIO, and doctors can quickly develop treatment plans to improve prognosis and efficacy.
Methods: The clinical data of patients with suspected AIO admitted to our hospital from May 2020 to May 2022 were retrospectively selected as the observation objects.

Intracranial vessels develop early in embryonic life through mutual interaction and integration of aortic arches giving the carotid arteries and intrinsic longitudinal neural system forming the posterior circulation. Due to the relatively short time and faster pace of completion of development, minor absent/persistent segments may give rise to either asymptomatic anatomical variants or hemodynamically significant changes. Intracranial vessels - both anterior carotid and posterior vertebrobasilar systems - are known to have many common anatomical variations like hypoplastic segments (A1 or P1 segments of anterior or posterior cerebral arteries) and persistent carotid-vertebrobasilar anastomotic channels.

Introduction: The traditional injection method of contrast media (CM) has limitations in terms of volume and imaging quality. Choosing the optimal CM injection method is crucial for ensuring high-quality images and accurate diagnosis in triple-rule-out computed tomography angiography (TRO-CTA). This study aims to investigate the application value of combining region of interest (ROI) with CM injection method alterations in TRO-CTA.
