Crohn disease is a frequent and multifactorial process wich usually affects people in early adult age and stays during the whole life with a unpredictable course. Because of this, it has a great importance to be able to assess when, where and how disease affects small bowel (most frequently affected), colon or both. Depending of this, the different therapies can be carried out with more chances of success. Different radiological and non radiological procedures has been used with the purpose to make a map of...

Crohn´s disease is a multifactorial disease where different etiologic elements: genetic, enviroment, lifestyle, food etc generate in the early beginning a segmental affectation of the mucosa consisting in aphthous ulcers alternating with normal mucosa. The evolution of the disease can stand there or progress to merge those mucosal lesions as well as to extend keeping a transmural and extramural way. 1. Active Inflamation. The typical features in active inflamation are edematous mucosa and ulcers giving an appareance called "cobble stone". (Fig 5) The proccess afects...

We use a 1.5 T MRI to perform the exams. The patient fasts 6 hours before the procedure and comes to hospital 1.30 h before the beggining of MRI. In hospital patiend drinks 1l -1,5 l of water (depending of tolerance)mixed with 4-5 sachets of commercial Polietilenglicol solution. What we get with this is to generate an adecuate distention of bowel that wouldn´t be possible using only water. After the ingestion patients goes to the toilet for emptying of the bladder.A nappy is placed inthe...

MRI has become in a necessary and powerful tool to diagnosis, describe and monitoring Crohn disease over the other radiological techniques. In comparison with CT, most of the features in the different phases of the sickness are similar but because ofthe frequentearly beggining of it MRI allows to control the evolution of the disease as much times as it is needed avoiding ionizing radiation as well. At the same time may evaluate the influence of the sickness in the normal peristalsis of the bowel with...
