Radiological Signs: The Key to Clinical Diagnosis

Since the first years of university medical education, it was difficult to remember the names of diseases, eponyms, pathways, gyral tracts, convolutions and other neuroanatomical structures. Semiology is the branch of medicine that studies, interprets and arranges the signs and symptoms of diseases in order to arrive at a diagnosis. Radiological semiology is the art and science of diagnosis by means of images, thanks to which we can reach a presumptive diagnosis. In radiology, to perform a correct semiology, it is necessary to have knowledge of different areas such as anatomy, physiology, pathology, if the patient has been previously treated or if the study is performed after a surgical approach.
