MRI IN THE INVESTIGATION OF MORTONS NEUROMA - WHICH SEQUENCES

Morton's 'neuroma' is a painful focus of peri-neural fibrosis, which m ay affect the interdigital nerves of the feet. Clinical diagnosis and Iocalization may be inaccurate. Computed tomography (CT), ultrasound a nd magnetic resonance imaging (MRI) have been used to confirm the diag nosis pre-operatively. Recently, MRI using T1-weighted sequences with fat saturation after i.v. Gadolinium DTPA has been suggested as the mo st effective MR sequence for depiction of Morton's neuroma of the fore foot. Our results show that Tf.-weighted axial and coronal images with an axial PSE T2-weighted sequence detect neuromata more consistently than an enhanced T1 fat suppressed sequence.
