This document discusses the craniovertebral junction (CVJ), which refers anatomically to the occiput, atlas, and axis vertebrae and their articulations. It describes the anatomy, embryology, biomechanics, imaging modalities including conventional radiography and MRI, and various measurements used to evaluate the CVJ. Common congenital and acquired abnormalities are also discussed, including basilar invagination, platybasia, assimilation of the atlas, and atlantoaxial instability. Imaging plays an important role in identifying bony and soft tissue anomalies, instability, and spinal canal compromise or cord compression.

This document provides an overview of the radiological anatomy of the tracheobronchial tree and techniques for demonstrating it. It begins with discussing the gross anatomy of the trachea and bronchi, their relations, blood supply and divisions. It then covers their appearance on various imaging modalities like plain radiography, CT, MRI, radionuclide scans and ultrasound. The techniques used for obtaining images with these different modalities are also described.

Presentation1, radiological application of diffusion weighted mri in neck mas...Abdellah Nazeer
This document summarizes the potential applications of diffusion-weighted MRI in evaluating neck masses. It discusses how DWI can help differentiate between benign and malignant neck masses based on apparent diffusion coefficient (ADC) values. DWI is also useful for predicting and monitoring treatment response in head and neck tumors by detecting changes in ADC values before changes in tumor size. DWI can help distinguish tumor recurrence from post-treatment changes based on qualitative and quantitative ADC assessments. The document concludes that DWI shows promise for applications in head and neck oncology but larger multicenter studies are still needed.
Lecture 8 of the COMP 4010 course taught at the University of South Australia. This lecture provides and introduction to VR technology. Taught by Mark Billinghurst on September 14th 2021 at the University of South Australia.
The document describes the cartilages that make up the laryngeal skeleton, including the thyroid, cricoid, epiglottis, arytenoid, corniculate and cuneiform cartilages. It discusses the functions of the larynx that must be preserved during organ preservation surgery, including phonation, respiration, deglutition and airway protection. Finally, it outlines the TNM staging system for laryngeal cancer of the supraglottis, glottis and subglottis regions.
This document discusses imaging of the cranio-vertebral junction. It begins by defining the cranio-vertebral junction and its key anatomical parts.

This document lists and describes various chest signs seen on imaging that can indicate different medical conditions. Some examples provided are the polo mint sign indicating acute pulmonary embolism, the gloved finger sign seen in allergic bronchopulmonary aspergillosis, and the tree in bud appearance commonly seen with tuberculosis infections. Different patterns such as reticulation, cysts, nodules and crazy paving are described along with the conditions they may suggest such as fibrosis, sarcoidosis or pneumonia. Specific signs for conditions like silicosis, round atelectasis, and congenital heart defects are also defined.

This document provides an overview of CT imaging of the cervical spine. It discusses the anatomy of the cervical spine including the typical vertebrae and curves. It describes the techniques used in CT imaging, including positioning the patient and acquiring scans to allow reconstruction in multiple planes. CT is useful for trauma evaluation and detecting fractures. Example images show normal anatomy on CT as well as a burst fracture. The document also provides some basics on lumbar spine and pelvis anatomy.
Drone use by firefighters isn't really new, departments all over have been using drones to assist in putting out fires for several years. While it is true that irresponsible use of UAVs is a major problem for fire departments, the responsible use of this technology can also be greatly beneficial to firefighting efforts – see how drones are being used for firefighting.
UAV(unmanned aerial vehicle) and its application Joy Karmakar
This document discusses unmanned aerial vehicles (UAVs), including their definition, history, components, applications, and disadvantages. UAVs are aircraft without human pilots that can be controlled autonomously or remotely. They have various applications both militarily and civilly, such as aerial surveillance, search and rescue operations, agriculture, filmmaking, and more. The key components of UAVs are the payload, air vehicle, navigation systems, and communications systems. India has developed several UAVs domestically such as Rustom, Nishant, and Lakshya for military purposes. The future of UAV technology remains dynamic with new discoveries expected over the next 16 years.
The document discusses nano unmanned aerial vehicles (UAVs or drones). It defines nano drones as extremely small drones less than 15cm intended for use in urban areas. They are remotely controlled and equipped with cameras and microphones. The document outlines the mechanisms of nano drones, including flapping wing designs. It discusses the advantages of nano drones like low cost and ability to operate in constrained environments, as well as disadvantages such as lack of self-power and risk of spying. Examples of specific nano drone models are provided.
SPINAL INTRAMEDULLARY TUMORS - COMPARISON OF MRI, INTRAOPERATIVE CHARACTERISTICSSreeramulu Srinivasan
This document provides a comparison of the MRI imaging characteristics, intraoperative features, and surgical management of various intramedullary spinal cord tumors, including astrocytoma, ependymoma, cavernoma, lipoma, and neurocysticercosis. Key differences in tumor morphology, enhancement patterns, consistency, vascularity, and resectability are described. Complete excision is typically possible for ependymomas, while internal decompression is often the extent of resection for astrocytomas and lipomas due to indistinct tumor margins. Radiotherapy may have a role in recurrent astrocytomas but is usually not needed for other tumor types.
This document discusses MR imaging of the inner ear. It begins with the embryology and anatomy of the external, middle, and inner ear. It describes the development of the membranous labyrinth from the otic placode and vesicle. Cross-sectional anatomy of the inner ear on MRI is shown, including the cochlea, vestibule, semicircular canals, and internal auditory canal. The document recommends an MRI protocol for inner ear imaging using 3D CISS sequences to evaluate structures surrounded by fluid like the 7th-8th nerve complex. MRI is useful for sensorineural hearing loss evaluation while CT is better for conductive hearing loss.

La communication publique face aux quartiers en difficultéIDcommunes
L’association des maires Ville & Banlieue de France et le réseau Cap’Com,
en partenariat avec l’agence IDcommunes, ont décidé
de réaliser une étude inédite à ce jour sur la communication
publique dans les quartiers en difficulté.
Avec l’objectif de cerner la problématique de communication
des villes comptant des quartiers en difficulté en analysant
de façon conjointe les registres politique et institutionnel
de cette communication, cette étude invite à de vraies pistes
de réflexion et d’amélioration.
Pour une majorité de maires et de dir’coms, la
communication conduite dans ces quartiers revêt un
enjeu politique primordial non seulement vis à vis de leurs
habitants mais aussi au regard de la ville toute entière.
Plusieurs questions émergent nettement et montrent
les spécificités et les difficultés de cette communication.
Les résultats de l’enquête, révélés lors du Forum Cap’Com
le 2 décembre 2010, seront mis en débat tout au long de
l’année 2011 afin de faire émerger des solutions pour la
communauté professionnelle des communicants et des élus.
