CONCLUSION
Conventional radiogram(CR) and MRI finding of proven 35 malignant tumors in the
oral and maxillofacial region were retrospectively compared to be of help in the
diagnosis and treatment
1. CR findings were diffuse bony destruction (42.9%), sort tissue shadow (20.0%),
floating tooth appearance (8.6%) and osteosclerotic change (5.7%).
2. MRI findings were soft tissue mass extension (65.7%), bone marrow involement
(343%), cortical bone destruction (40.0%), marrow infiltration with intact cortex (2.9%),
fat plane obliteration(543%), lymph node obliteration (22.9%), contrast enhancement
(42.9%) and osteosclerosis (2.9%).
3. The MRI studies provided information, which was not present on CR in the tumor
extension to mouth floor, masticator space, parapharyngeal space, infratemporal fossa,
submandibular gland, nasal cavity and lymph node involvement.
4. Diagnostic accuracy were 45.7% in CR and 77.1% in MRI. In 2 cases, CR was
superior to MRI in detecting malignancy.
