Introduction

This web site is intended to be a tutorial for learning different types of radiological modalities and applying them to various parts of the humen body, finally to collect useful differential diagnosis for each radiological sign to reach the proper diagnosis. This may appear to be a basic task in medicine but, in fact it is a complex task based on careful observation, sound anatomical principles, and knowledge of physiology and pathology.Look to the right side bar, choose your aim from index of contents, you will find head and neck in this main page while other systems are listed in the index and try to enjoy the information included.
