Functional magnetic resonance imaging (fMRI) in conscious animals is evolving as a critical tool for neuroscientists. The present study explored the effectiveness of an acclimation procedure in minimizing the stress experienced by the animal as assessed by alterations in physiological parameters including heart rate, respiratory rate, and serum corticosterone levels. Results confirm that as the stress of the protocol is minimized, there is a significant decrease in head movements and enhancement in data quality. The feasibility of improving the quality of fMRI data acquired in alert rats by utilizing a relatively simple technique is presented.

Background: Headache disorders are prevalent often leading to disability. The rectus capitus posterior major muscle (RCPMaj) may contribute to headache symptoms via nociceptive convergence and myodural bridging.
Objectives: To establish guidelines for needle length and needle angle to mitigate risks during dry needling RCPMaj.

Purpose: To evaluate the feasibility of aortoiliac CT-Angiography (CTA) using dual-source photon-counting detector (PCD)-CT with minimal iodine dose.
Methods: This IRB-approved, single-center prospective study enrolled patients with indications for aortoiliac CTA from December 2022 to March 2023. All scans were performed using a first-generation dual-source PCD-CT.

Objective: CSF leaks are a significant source of patient morbidity following intradural spine surgeries. Watertight dural closure is crucial during these procedures to minimize the risk of a CSF leak. This study reports postoperative outcomes and changes in patient management after switching to penetrating titanium clips for dural closure in a large cohort of pediatric patients receiving a tethered cord release (TCR) or a selective dorsal rhizotomy (SDR).

Objective: The purpose of this study was to present a newly designed 3D-printed personalized model (3D PPM) of a radiofrequency needle guide with a maxillary fixation for gasserian ganglion (GG) puncture.
Methods: Implementation of 3D CT-guided radiofrequency therapy of the GG with and without use of 3D PPM was analyzed. The following parameters were assessed: radiation time, dose area product, air kerma reference point, pain severity during the puncture needle insertion, prosopalgia regression degree (according to visual analog scale) and the severity of facial numbness (according to the Barrow Neurological Institute scale) in the early postoperative period, and postpuncture complications.

Objectives: Pancreatic diffusion-weighted imaging (DWI) has numerous clinical applications, but conventional single-shot methods suffer from off resonance-induced artifacts like distortion and blurring while cardiovascular motion-induced phase inconsistency leads to quantitative errors and signal loss, limiting its utility. Multishot DWI (msDWI) offers reduced image distortion and blurring relative to single-shot methods but increases sensitivity to motion artifacts. Motion-compensated diffusion-encoding gradients (MCGs) reduce motion artifacts and could improve motion robustness of msDWI but come with the cost of extended echo time, further reducing signal.
