Primary tumors of the foot: MR imaging.
The findings at magnetic resonance (MR) imaging of eight patients with primary tumors of the foot were compared with those at gross pathologic examination. In all cases, there was excellent correlation between the two studies. When compared with computed tomography (CT), MR imaging was superior in defining the presence and extent of local disease. While the appearances of various foot neoplasms are nonspecific, the ease of multiplanar imaging, the superior contrast resolution, and the sensitivity to marrow abnormalities are major advantages of MR imaging over CT in staging foot neoplasms. These advantages are crucial when foot-sparing curative resection of a malignancy is contemplated. The combination of plain radiography and MR imaging may be all that is necessary for optimal preoperative detection and local staging of tumors of the foot.
