Background The Canadian Special Operations Forces Command conducts explosives operations and training which exposes members to explosive charges at close proximity. This 5‐year longitudinal trial was conducted in follow‐up our initial examined military breachers with MRI EEG pre post blast exposure. Purpose To examine brain findings personnel exposed multiple repeated exposures. Study Type Five‐year prospective trial. Population Ninety‐two males aged 23–42 an average of 9.4 years Field...
We describe a minimally invasive endovascular approach to treat an arteriovenous fistula of the scalp. performed direct puncture lesion through patient's scalp for liquid embolic agent injection along with external compression superficial temporal artery perform "manual pressure-cooker technique." The combination these techniques resulted in excellent clinical and radiographic outcome.
Objective: Percutaneous biopsy of lung nodules is established as a safe procedure with high diagnostic yield and accuracy. Its role in the diagnosis subcentimeter is, however, less clear. The goal this study was to evaluate yield, accuracy, safety computed tomography (CT)-guided needle nodules. Material Methods: A retrospective review prospectively maintained database over 12-year period identified 133 eligible CT-guided biopsies lesions ≤1 cm. Diagnostic accuracy for malignancy were...
Stereotactic radiosurgery (SRS) is an effective treatment for vestibular schwannomas, offering high rates of tumor control and low neurological risks. Long-term complications SRS are not fully understood, with several cases malignant transformation reported in the literature. We report case a 50-year-old female no prior history neurofibromatosis who presented 2013 MRI evidence benign schwannoma. Despite CyberKnife SRS, she 6 years later new onset neurologic symptoms. Further investigation...
Background The COVID-19 pandemic has changed the way medicine is practiced, including implementation of virtual care in many specialties. In field interventional neuroradiology (INR), clinics are an uncommon practice with minimal literature to support its use. Our objective was report prospective, single-centre data regarding patient and physician experience INR for routine follow-up appointments. Methods We surveyed all patients that participated a clinic appointment at our hospital over 3...
Background: The value of endobronchial ultrasound–guided transbronchial needle aspiration (EBUS-TBNA) in the mediastinal staging lung cancer has been well established. However, data regarding its utility diagnosis intrapulmonary lesions sparse. This study assesses sampling convex probe EBUS-visible not visualized by white-light bronchoscopy. Methods: A retrospective analysis EBUS-TBNA was performed between January 2010 and March 2015. Patients with visible bronchoscopy were excluded from...
Spontaneous perforation of gallbladder is a severe and infrequent complication acute cholecystitis that requires early accurate diagnosis. Concomitant development intrahepatic collections rarely observed in such cases. The present report emphasizes the relevance imaging studies this setting, describing typical sonographic tomographic findings for diagnosis condition.
 O estado de Rondônia estava incluído nas zonas exclusão para o plantio do algodão geneticamente modificado. Essas áreas foram instituídas em 2005, pela Comissão Técnica Nacional Biossegurança (CTNBio), com objetivo preservar a variabilidade algodoeiros não cultivados (nativos e naturalizados) eventuais efeitos adversos decorrentes fluxo gênico modificados. No entanto, os insetos endêmicos da região, pragas inimigos naturais, associados ao algodoeiro modificado, levantados. Tais informações...
<h3>ABSTRACT</h3> <h3>BACKGROUND AND PURPOSE:</h3> Previous studies have suggested that patients suffering an in-hospital stroke (IHS) may face delays in treatment and worse outcomes compared to with community-onset strokes (COS). However, most occurred when intravenous thrombolysis was the primary treatment. This study aimed examine of experiencing IHS endovascular thrombectomy (EVT) era. <h3>MATERIALS METHODS:</h3> Single-center retrospective cohort older than 18 years acute ischemic (AIS)...

Purpose Cerebral hyperdensities can appear on head computed tomography (CT) images performed early after endovascular treatment (EVT) in patients with acute ischemic stroke and may be secondary to contrast staining or hemorrhagic transformation. The aim of this study was determine how the high-density sign CT affects mortality clinical outcome whether parameters predict conversion unfavorable outcome. Methods We retrospectively reviewed a database who underwent EVT mechanical thrombectomy...
Objective The present study was aimed at describing a case series where preoperative diagnosis of intestinal complications secondary to accidentally ingested dietary foreign bodies made by multidetector-row computed tomography (MDCT), with emphasis on complementary findings yielded volume rendering techniques (VRT) and curved multiplanar reconstructions (MPR). Materials Methods authors retrospectively assessed five patients surgically confirmed (perforation /or obstruction) unsuspected...
The aim of this study was to validate a novel medical virtual reality (VR) platform used for image segmentation and contouring in radiation oncology 3D anatomical modeling simulation planning interventions, including surgery. first step the validation verify quantitatively qualitatively that VR can produce substantially equivalent models, contours, measurements those generated with existing commercial platforms. To achieve this, total eight sets 18 structures were segmented using both...

Reversible sulcal fluid-attenuated inversion recovery (FLAIR) hyperintensity is a rare imaging finding that could be seen on magnetic resonance (MRI), in patients with migraine aura. Herein, we present patient who was admitted to the emergency department severe headaches, numbness right side of body, and visual changes. MRI showed FLAIR occipital lobes, no other abnormality. The diagnosed aura by neurology follow up resolution finding, supporting diagnosis. Sulcal nonspecific can occur or...
This is a case of 30-year-old right-handed male patient who presented to the hospital in 2014 after hitting his head on mat during wrestling match followed by headache and temporary peripheral vision limitation. The patient’s past medical history was unremarkable. On physical examination, Glasgow Coma Scale 15 with no focal neurological deficits. Unenhanced computed tomography (CT) enhanced brain magnetic resonance imaging (MRI) were performed (Figure 1). managed conservatively, follow-up CT...
