 What is 'a walk though Radiology'? 

‘A walk through Radiology’ is a project which was born after 20 years of teaching students of the 6th year of Medicine. If consists of a collection of cases which are shown on the screen in order to offer the student a first contact with radiological imaging and give a visual training, both to distinguish the different ways of radiological exploration and to identify and describe the most common findings. It does not pretend to be an exhaustive lesson about radiology, but a practical tool to train user's visual perception. How can we do it? Showing a number of cases wide enough for the user to "walk" from one to another. It is organised in two series of different images, depending on whether they correspond to normal or pathological cases.

From a technical point of view, ‘A walk through Radiology’ is a display of slides on the screen. To move from one screen to the others, you just have to click the boxes so that the whole training is carried out only by using the mouse. Se ha desarrollado en Powerpoint (Microsoft Office 2000).

The interest of our students and the support of the University motivated the edition of a CD-ROM in january 2000, and the presentation 'on line' in Internet. Actually, a new version, improved and translated into two languages, has been edited.

The training (2nd edition) has 72 normal cases and 75 pathological cases in two collections. In each collection, the whole practice can be carried out from one extreme to the other, case by case, by forward and backward buttons. Some central pages such as "home pages" have been included which allows a selectively move, from central pages of normal images or pathological images.

A first screen with the main image of the case with few or no information is displayed. On the following screen, answers to basic questions are offered and, sometimes, additional explanations about the technique, the projection or the case itself. Answers are displayed by a series of animated transitions which are automatically carried out. Once the object transitions have finished, a visual and sonorous sign indicates that you can go on whenever you want.

'A walk through Radiology' is an original idea of Manuel Martínez Morillo and Francisco Sendra Portero, developed in the Department of Radiology and Physical Medicine of the University of Malaga.

 Why a walk through Radiology? 

Besides knowing the expression of diseases in patients, the student of Medicine familiarizes himself with the most common diagnostic procedures. In this point, the study of radiology has great importance. 

Teaching radiology cannot be separated from its practical aspect. There is a series of radiological examinations, each of which represents in a different way the morphological and/or functional normality or abnormality of an organ or an anatomical structure. The appearance of the final image depends on the physical phenomenon which originates the image. Sometimes they are originated by X rays, as the conventional radiographs, with all theirs versions, or the computed tomography. Others use ultrasounds, as the echography, radiofrequency pulses, as the magnetic resonance, or the radiation coming from those organs where an isotope has been placed on, as the isotope scanning, the SPECT and PET. Other factors such as the used technique, the position of the patient, age, sex and, of course, the presence or absence of pathology open a great diversity of possibilities of graphical representation of these diagnostic images which make essential to provide a sufficient number of hours of visual training during traineeship.

Multimedia applications can contribute to a personalized teaching. This training provides an additional number of hours of revision adapted to each student's rhythm.

It consists of a very variegated collection of cases, representing a series of fundamental findings in radiology, in which the user can visit the images calmly, like walking. That's why its name. It is not necessary to have knowledges on informatics, just to drive at a basic user level. The student can discover at his own rithm what kind of findings are more difficult to identify and what problems are found in the relation between visual perception and theorical knowledges.



From 1985 a practical training for students of the sixth year of Medicine of the University of Málaga have been carried out in the Department of Radiology and Physical Medicine in which several cards with slides and viewfinders of microfiles were used and the student had a written script and could consult the atlas of Radiology.

The main advantage of this practical training was that it was a training guided by the student himself, who could manage his time in order to progress following his own rhythm. So, the professor only takes part in case of a doubt whose answer could not be found in the atlas of Radiology. 

The main disadvantages were the material deterioration due to the use (cardboard cards, slides, cover glass and even the screen of the viewfinders) as well as the inconvenience and loss of time for the student when consulting written scripts and radiological atlas.

In October 1998, a thesis on multimedia application for teaching thorax computed tomography (ALGARRA, 1998) was written. It was called AULAGA project and was a product of the enthusiam of a radiologist of the University Hospital who was a regular collaborator of research projects in this Departmen and very keen on computer programming. As a part of this work, a series of user's trials were carried out, including specialist doctors, residents and students of the sixth year of Medicine. Due to the success of the application among the students and taking into account that a practical training with viewfinders was taking place in 1997-1998, the old idea arose: to adapt the practical training with viewfinders to a modern and present-day environment which was not affected by deterioration due to the use, creating a multimedia application..

During the course 1998-99 a computer based training, which constituted the first draft of this project, started in our department. Thaks to the information provided by the students, the observation during the training periods and the suggestions of colleges and friends, a large quantity of corrections and apportations have been done giving, along these years, the form of the actual version.

† Professor Manuel Martínez Morillo died on August 19, 2015. This project will continue to be updated in his memory.


 The application 'on line' 

The training can be performed 'on line' completely, although it can be somewhat slow depending on the data transfer limitations of the net.

 The training in CD-ROM 

Unlike the 'on line' presentation, the trainig in CD-ROM does not depend on the internet restrictions. Furthermore it contains high resolution images which profit the computer screen in all its surface, obtaining a more adequated visual effect.
