Across emergency rooms all over the world, thousands of patients are referred for brain CT scans daily. A radiologist often has to interpret the scan or a consultation has to be made to a neuros- geon to review the scan. Most of this happens late at night and is a signi?cant source of discontent. Thus having frontline phy- cians to be pro?cient in interpreting the emergency brain CT scan improves the ef?ciency of the whole pathway of care and is pot- tially life saving as time is of the essence for many patients with severe brain injury or stroke. Underlying all of the above and the primary reason for writing this book is because the skill required to determine an immediate life threatening abnormality in a brain CT scan is so basic and can be learned in a short time by people of various backgrounds and certainly by all physicians. ‘Indeed the emergency head CT scan is comparable to an electrocardiogram in usefulness and most de?nitely as easy to learn. ’ This book is therefore written for ca- givers the world over to demystify the emergency CT brain scan and to empower them to serve their patients better. It is obvious to me from the response from people I have had opportunity to teach this subject that not only is there a desire to learn this basic skill but also people learn it quickly and wonder why it has not been presented so simply before.

Most imaging books are ordered according to underlying etiology. However, in real life clinical practice, radiologists usually make their differential diagnoses according to the image patterns, as the etiology is often unknown. Brain Imaging with MRI and CT presents over 180 disease processes and normal variants, grouping entities by these basic patterns to accentuate differential diagnostic features. High quality CT and MRI scans show multiple typical and distinguishing images for each entity. Common and unusual clinical scenarios are described, including dilated perivascular spaces, capillary teleangiectasia, Susac's syndrome and desmoplastic infantile ganglioglioma. Both basic and advanced imaging techniques are used, reflecting the reality of clinical practice. This image-focused book emphasises the most pertinent clinical information relevant to the diagnostic process. Trainee and practising radiologists will find Brain Imaging with MRI and CT an invaluable and clinically relevant tool for learning and teaching.

Brain Imaging: A Guide for Clinicians is designed to provide a foundation of information necessary to those wishing to integrate brain imaging into their practice, or to those that currently review brain scans but have minimal formal training in neuroimaging. The guide covers a range of topics important to those using brain imaging, such as the strengths and weaknesses of the many different techniques currently available, the factors that may influence the use of imaging data, common pitfalls or artifacts that may be misleading to the clinician, the most appropriate techniques to use given a specific clinical question or condition, how to interpret information presented on a brain image, and also how many pathological conditions appear on a variety of brain scanning techniques or sequences. This guide also provides detailed information regarding the identification of primary brain regions, anatomical structures, systems or pathways using both two-dimensional and three-dimensional imaging techniques. A brain atlas is included using both CT and MRI sequences to facilitate the reader's ability to identify most primary brain structures. A novel color-coded system is used throughout this guide to assist the reader in identifying slice locations and orientations. Images with green borders are displayed in the axial plane, with the slice location being shown on other orthogonal image planes by a green line. Similarly, images with a red border are displayed in the coronal plane and those with a blue border are displayed using a sagittal plane; red and blue reference lines are displayed on orthogonal slices to identify the slice location. The crosshairs formed by the color-coded reference lines optimize the reader's ability to identify primary anatomical structures or pathological markers and processes. This book is written in a manner to progress from a general description of the clinical use of brain images and the interpretation of brain scans, to more complex chapters involving neuroanatomy and imaging technology. Real life examples of clinical cases are integrated into all chapters of this guide. Brain Imaging: A Guide for Clinicians provides hundreds of images derived from traumatic and non-traumatic pathologies to provide the reader with examples of conditions most often seen in the clinic. PEARL-PERIL sections outline critical information for the clinician, along with many tables and charts designed to provide general information required when interpreting brain images.

This book describes the basics, the challenges and the limitations of state of the art brain tumor imaging and examines in detail its impact on diagnosis and treatment monitoring. It opens with an introduction to the clinically relevant physical principles of brain imaging. Since MR methodology plays a crucial role in brain imaging, the fundamental aspects of MR spectroscopy, MR perfusion and diffusion-weighted MR methods are described, focusing on the specific demands of brain tumor imaging. The potential and the limits of new imaging methodology are carefully addressed and compared to conventional MR imaging. In the main part of the book, the most important imaging criteria for the differential diagnosis of solid and necrotic brain tumors are delineated and illustrated in examples. A closing section is devoted to the use of MR methods for the monitoring of brain tumor therapy. The book is intended for radiologists, neurologists, neurosurgeons, oncologists and other scientists in the biomedical field with an interest in neuro-oncology.

This concise integrated handbook looks at all available imaging methods for head and neck cancer, highlighting the strengths and weaknesses of each method. The information is provided in a clinical context and will guide radiologists as to the information the clinician actually needs when managing a patient with head and neck cancer. It will also provide the clinician with the advantages and limitations of imaging. The text therefore deals with Ultrasound, CT and MRI. The initial chapters aim to give the reader a core knowledge, which can be used in imaging by the various methods described. The subsequent chapters are directed towards clinical problems and deal with the common cancers in a logical order.

"Patients who suffer minor brain injuries experience unnecessary ionizing radiation in the form of a non-contrast head CT scan despite the dearth of evidence supporting standard CT scans for all brain injuries. Exposure to ionizing radiation increases the incidence of certain types of cancer. This evidence-based practice change project assesses the attitude of clinicians towards evidence-based clinical decision support tools, specifically the Canadian CT head rule. The use of highly sensitive clinical decision support tools is supported in the literature to help healthcare providers mitigate the risk associated with unnecessary use of CT scan imaging studies. The project was conducted in an academic medical center in the Northeast, utilizing healthcare providers caring for adult patients admitted to the hospital who sustained a minor brain injury due to a fall during their inpatient stay. The standard practice at this institution was to evaluate patients with minor brain injuries with non-contrast head CT scan. The Evidence-Based Practice Attitude Scale was utilized in conjunction with one-on-one instruction regarding the Canadian CT Head Rule. Participants were asked to complete a pre-test comprised of four clinical scenarios regarding patients with minor brain injuries according to what they believed to be standard practice. Subsequently, they were asked to complete the same clinical scenario questions by applying the clinical decision tool. Analysis utilized descriptive statistics, correlations of attitude domains, and knowledge increase. The healthcare provider's attitude towards innovation is an antecedent toward the likelihood of adopting evidence-based practices guidelines into clinical practice, and there was an increase in knowledge regarding the use of clinical decision support tools. Keywords: clinical decision support; Canadian CT Head Rule; Head CT Scan; minor brain injury" -- Abstract.
