Methods and Materials
The MRI of 24 patients with 26 onychomatricomas of fingers or toes were reviewed by 2 independent readers in this retrospective and monocentric study for patients between 1994-2015.
All patients included in the study had preoperative MRI on 1.5 or 3 Tesla and were then operated with histopathological diagnosis.
The MRI sequences are T1,
T2 (STIR,
T2,
Ciss) and T1 gadolinium Fatsat.
MRI parameters were FOV=40mm,
size of slice 2-3mm,
matrix 256x256 or 192x192.
The MRI coil was a loop of 4 cm.
The proximal core of the tumor in the nail matrix and the distal component with filamentous expansions in the nail plate were separately analysed according to signal,
size and morphology.
