[Preliminary experience of 16-layer three-dimensional computed tomography in diagnosis and treatment of arteriovenous malformations].
OBJECTIVE
We assessed the value of 16-layer three-dimensional computed tomography angiography (3D-CTA) and digital subtraction angiography (DSA) in diagnosis of the arteriovenous malformations (AVM).


METHODS
16 patients with AVM were examined by 16 layers CT scan and DSA.


RESULTS
The DSA imaging provided excellent visualization in all of patients, including size, location, and feeding arterial of AVM. The value of the diagnosis of the nidus malformation vascular by 3D-CTA was similar to that by DSA, however, CTA was not good at diagnosis of the third feeding artery of AVM. The three-dimensional reconstruction also further revealed the relation of lesion and surrounding tissue which is helpful in making an appropriate decision before treatment. Differences in dates were compared using the t test. P<0.05 was considered statistically significant.


CONCLUSIONS
16-layer 3D-CTA was a superior approach for diagnosis and follow up of the AVM.
