Zusammenfassung
Purpose: This study investigates the efficacy of 3 Tesla magnetic resonance (MR) microimaging for characterisation of primary melanoma. Technologies currently in use for non-invasive characterization of melanoma (confocal microscopy, optical coherence tomography, or high frequency ultrasound) are limited by restricted penetration depth. In contrast, MR microimaging can determine the full depth of all tumors. Methods: Five patients with primary melanomas of lateral dimension 1cm or greater were imaged with a 3.7cm surface coil using a 3D gradient echo sequence (1). Nominal spatial resolution was 0.18×0.12mm in-pl…
