[The diagnostic value of CT for arteriovenous malformations of jaws]
1Department of Radiology, Ninth People's Hospital,Shanghai Second Medical University, Shanghai 200011, China.
Objective:
To evaluate the diagnostic value of CT for arteriovenous malformations (AVM) of jaws.
Methods:
12 cases of central vascular malformations of jaws comprised this study group, 5 cases in maxilla and 7cases in mandible, respectively. The X-ray projection included panoramic radiography, Water's position and posterioanterior and lateral oblique view of mandible. The CT scans were obtained on Somatom ART and the axial and coronal scanning modalities were applied.
Results:
Radiographically different signs of the AVM of jaws were demonstrated, X plain film has no pathognomic features. The CT features included lytic expansion of bone, expanded space of marrow, obliteration of trabeculae and intact cortex of jaws. These signs were demonstrated very well in bone window setting. There were three forms of demonstrations of AVM of jaws as following: (1) local unilocular, (2) diffused unilocular, (3) multilocular.
Conclusion:
CT is helpful for early diagnosis of AVM of jaws, and can provide the guidance for the direct puncture embolization.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
