The intent of this book is to provide 200 need-to-know neuroradiological diagnoses in Brain Imaging for the radiology residents, neuroradiology fellows and practicing radiologists. The book is ideal for those who are preparing for their MD, DMRD, DNB and FRCR examinations. The format simulates the way radiology residents are generally taught. The teaching of radiology residents is typically performed using the ‘case discussion technique’ wherein the resident is usually unaware of the diagnosis and is presented with specific images and allied clinical details. The discussant is required to determine pertinent imaging findings and generate a reasonable differential diagnoses based on the imaging findings and relevant clinical history, and, by the process of elimination, decide on the most likely diagnosis. A similar ‘case discussion format’ has been adopted in this book, providing the readers with images from the latest available imaging modalities and covering all major diseases that are encountered in everyday clinical practice. In reading each case, the reader should direct attention to the clinical history and provided radiological images. After arriving at a diagnosis, the reader should then flip the page for the correct diagnosis as well as the supplementary commentary on each case. An attempt has been made to answer almost all frequently asked questions in the radiological examinations. The commentary although not all-encompassing serves as a fundamental framework on which one can add information from more comprehensive texts. Each case is followed by distinct learning points and the best-diagnostic-clue, so as to provide novice as well as experienced readers a brief but succinct summary of the particular disease entity. A concise list of particularly relevant references has also been provided. Purposely, the cases are randomly assorted and not organized by disease-type into congenital, infective or neoplastic entities so as to provide the readers with a realistic examination scenario. The cases (in the textbook) based upon the varying difficulty levels have been categorized into Basic, Intermediate and Advanced (50 cases in each). In addition, 50 online cases are also provided. This richly illustrated series contains cases that are a compilation of illustrative teaching material collected over past several years and the authors sincerely hope that the readers will find this book enormously useful. The readers' comments and questions are heartily welcomed.
