Three-dimensional CT angiographic assessment of vascular diseases using various postprocessing techniques: the voxel transmission and cruising eye view methods and their respective merits.
BACKGROUND
To assess the clinical usefulness of three-dimensional CT angiography (3D-CTA) with newly-developed three-dimensional reconstruction techniques; voxel transmission (VT) and cruising eye view (CEV) methods, for performing minimally invasive diagnostic imaging of vascular diseases.


METHODS



METHODS
retrospective comparative study.


METHODS
University Hospital, Japan.


METHODS
fifty-five patients with vascular lesions confirmed by catheter angiography (20 patients with aortic aneurysms, 10 patients with aortic dissection, and 25 patients with peripheral arterial occlusive disease).


METHODS
minimally invasive, three-dimensional diagnosis of vascular diseases.


RESULTS
Angiogram-like images with a diagnostic quality similar to that of catheter angiography were obtained by the three-dimensional CT angiography/voxel transmission (3D-CTA/VT) method. This method is useful for treatment planning and also valuable for assessing the effectiveness of treatment. Three-dimensional endoscopic images of the vessel interior were obtained by the three-dimensional CT angiography cruising eye method (3D-CTA/CEV). This also yielded precise information about the relationship between the vascular lesions and the aortic orifices.


CONCLUSIONS
Three-dimensional CTA/VT and three-dimensional-CTA/CEV enable visualisation of vascular lesions from an infinite number of viewing angles, and are useful as minimally invasive diagnostic techniques for imaging the vasculature.
