Aims and objectives
Crohn's disease is an inflammatory process of the gastrointestinal tract usually affecting the small intestine but it can attack every part of the bowel and digestive tract.
Typically indentified changes affect limitated areas of the bowel,
are asymetrical with superficial to deep ulceration of the wall.
The diagnostics and monitoring of the disease can bring a lot of difficulties and still the most effective methods are to be searched as patients are usually young adults with tendency to relapses and serious complications.
MRI is known to be an important and safe diagnostic modality to discover and examine morphological changes in the bowel but nowadays we also need more tools to interpret the pathologies.That is why the functional assessment of discovered changes is very needed.
The aim of this study was to compare a diagnostic efficiency of DWI (diffusion weighted imaging) sequence with creating ADC (apparent diffusion coefficient) maps for different values of b parameter and DCE-MRI (dynamic contrast contrast enhanced MRI) in assessment of active and chronic Crohn disease.
