Static and dynamic magnetic resonance imaging of the pelvic floor

MRI assessment of pelvic floor dysfunction is still fairly recent. It is a fast expanding field, owing to its safety and simplicity when compared to o ther imaging modalities. The possibility of direct dynamic imaging is a decisive input, and it can b e coupled to a clinical examination at the magnet. The most widely used seq uences are T2 weighted fast TSE or fast gradient echo, in the sagittal and frontal planes. Dynamic MRI of the pelvic floor allows pre-operative stagin g of prolapse, detection of hidden prolapses and assessment of muscle troph icity. Post-operatively it allows assessment of surgical results and failur es or recurrences.
