Abstract The objective of this pilot study was to assess the reliability superb microvascular ultrasound (SMI) for measurement cerebrospinal fluid (CSF) flow within VPS systems as an indirect sign shunt dysfunction. Asymptomatic hydrocephalus patients, with a system implanted between 2017 and 2021, were prospectively enrolled in study. Using SMI, CSF proximal distal catheters analysed. Before after pumping reservoir, intraabdominal free fluid, optical nerve sheath diameter (ONSD), papilla...
Background. Previous studies have suggested that men and women process emotional stimuli differently. In this study, we used event-related functional magnetic resonance imaging (fMRI) to investigate gender differences in regional cerebral activity during the perception of positive or negative emotions. Method. The experiment comprised two conditions (positively/negatively valenced words) which fMRI data were acquired. Results. Thirty-eight healthy volunteers (19 males, 19 females)...
The human attachment system is activated in situations of danger such as potential separation, threats loss a significant other and insecurity on the availability figure. To date, however, precise characterization neural correlates healthy individuals lacking. This functional magnetic resonance imaging (fMRI) study aims at characterizing distinctive substrates by exposure to vs. non-attachment scenes. Healthy participants (N = 25) were presented scenes from Adult Attachment Projective...
To demonstrate the importance of calibration measurements in 3 Tesla proton magnetic resonance (MR) spectroscopy (1H-MRS) thermometry for human brain temperature estimation routine clinical applications. In vitro MR to obtain constants water-chemical shift was conducted at with a temperature-controlled phantom, containing pH-buffered aqueous solution N-acetyl aspartate (NAA), creatine (Cr), methylene protons Cr (Cr2), dimethyl silapentane sulfonic acid (DSS), and sodium formate (NaFor)....
Purpose To investigate intersite variability of clinical functional magnetic resonance (MR) imaging, including influence task standardization on and use various parameters to inform the clinician whether reliability a given localization is high or low. Materials Methods Local ethics committees approved study; all participants gave written informed consent. Eight women seven men (mean age, 40 years) were prospectively investigated at three experienced MR sites with 1.5- (two sites) 3-T (one...
Patients receiving high cumulative effective doses (CED) from recurrent computed tomography (CT) in a real-life setting are not well identified. Evaluation of causes and patient characteristics may help to define individuals potentially at risk radiation-induced secondary malignancies.Patients who received CED > 100 mSv CT scans during October 2012 April 2020 tertiary university center were identified with the radiological radiation dose monitoring system. The primary disease referral...
Abstract Background Chronic pelvic pain, in particular dysmenorrhoea, is a significant yet unresolved healthcare problem gynaecology. As interoceptive sensitivity and underlying neural mechanisms remain incompletely understood, this functional magnetic resonance imaging ( fMRI ) study assessed behavioural responses to visceral stimuli primary dysmenorrhoea PMD ). Methods Women with N = 19) without psychological comorbidity healthy women 20) were compared respect sensory pain thresholds,...
Abstract Background To model the effect of isolated bilateral sagittal split osteotomy (BSSO) on changes in posterior (PSD), superior (SSD), and medial space dimensions (MSD) temporomandibular joint. Methods Using a retrospective cohort study design, pre- postoperative (immediately after surgery; 1 year follow-up) cone-beam computed tomography measurements 36 patients who had undergone BSSO for mandibular advancement were compared with control group 25 subjects from whom odontogenic cyst was...
This study provides first data about the spatial variability of fMRI sensorimotor localizations when investigating same subjects at different sites.Results are comparable to a previous patient study.We found median between-site 6 mm independent task (motor or sensory) and experimental standardization (high low).An intraclass correlation coefficient analysis using quality measures indicated major influence site on variability.In accordance with this, within-site localization was considerably...
Occlusion of a ventriculoperitoneal shunt system is potentially life-threatening complication in patients suffering from hydrocephalus. However, there no imaging established as standard approach this acute setting. In the present study, we evaluate use superb microvascular for investigation patency systems. Simulation low flow rates cerebrospinal fluid through small diameter CSF was performed dedicated phantom order to proof principle (SMI) being feasible measurement slow system. SMI able...
This paper presents the preliminary results of applying multi image photogrammetric techniques for three-dimensional monitoring intraoperative brainshift. The "brainshift" is motion cerebral structures occurring in neurosurgery after craniotomy (opening skull order to access brain surgical repair). causes this effect are mainly changes pressure and loss cerebrospinal liquid. phenomenon brainshift can influence negatively planning execution neurosurgical intervention. A research project at...
<b><i>Background:</i></b> Premature fusion of cranial sutures affects skull development and leads to head deformity. Intracranial pressure increase brain growth restriction can occur in untreated craniosynostosis. Operative treatment aims achieve an immediate long-lasting correction shape that is close the average prevent or release possible increased intracranial by increasing volume (ICV) normalizing ICV if it already below standards. This study was designed...
Rhinoresistometry (RRM) is implemented along with active anterior rhinomanometry (AAR) and can evaluate nasal dimensions [hydraulic diameter (HD)]. As acoustic rhinometry (AR) time-consuming, the authors investigated if RRM be an efficient alternative to AR in dimension assessment orthognathic surgery. In patients undergoing maxillary advancement impaction (cases) removal of cysts (controls), evaluated AR, before 1 year after Furthermore, correlation HD Nasal Obstruction Symptom Evaluation...
Lateral mass screw fixation is the standard for posterior cervical fusion between C3 and C6. Traditional trajectories stabilize but carry risks, including nerve root vertebral artery injuries. Minimally invasive spine surgery (MISS) gaining popularity, present anatomical challenges. This study proposes a novel pars interarticularis trajectory to address these issues enhance in-line instrumentation with pedicle screws. A retrospective analysis of reformatted CT scans included 10 patients....
Abstract Purpose To collect and analyze radiation dose-related data as part of international cooperation; to define diagnostic reference levels (DRL) for 24 X-ray projections in plain radiography (DX) considering anatomical region, clinical task, procedural technique; harmonize the exposure practice across country borders. Methods A multicenter study was performed Austria, Germany, Italy, Switzerland 2022–23 provide data. Healthcare facilities were asked processed from their dose management...
