3D Ct Angiography

An image guide for aneurysm embolization based on three dimensional CT angiography is reported. Multiplanner reformation (MPR) can measure the neck and dome of the aneurysm accurately enough to select the first coils for aneurysms. For neck evaluation, cut model and virtual endoscope are helpful because we can observe the neck from inside of dome or parent artery. Proximal arteries are visualized by 3D images and MPR if needed. Using laser lithography, we can get a real model of aneurysm and parent artery through which we can insert microcatheters and coils. 3D CTA is a dependable modality for embolization of cerebral aneurysms.

Rotational Digital Subtraction Angiography

Sixteen ruptured aneurysms in 16 patients considered endovascular embolizations were examined. The findings of axial source images (axial images) and reconstructed three-dimensional CT angiography (3D-CTA) of helical CT were compared to those of rotational digital subtraction angiography (DSA). The aneurysmal neck and arterial branches adjacent to the neck were closely investigated. In seven out of 16 cases (43.8%), information provided by axial images and/or 3D-CTA was more useful than that of rotational DSA in evaluating the aneurysmal neck and arterial branches. Helical CT can provide valuable information on ruptured aneurysms that cannot be obtained by rotational DSA in some patients. This technique is useful to obtain anatomical information about aneurysms and to select the best therapeutic method.

Objective. To evaluate the diagnostic value of low-dose 256-slice CT angiography (CTA), MR angiography (MRA), and three dimensional-digital subtraction angiography (3D-DSA) in cerebral aneurysms. Methods. CTA, MRA, and 3D-DSA were performed in all enrolled patients to explore the diagnostic significance of the three different examinations. Results. There were 92 aneurysms confirmed during DSA and surgery in 79 patients. The diagnostic coincidence rates of DSA, CTA, and MRA were 96.7%, 89.1%, and 86%, respectively. The diagnostic coincidence rates of CTA and MRA were lower than those of DSA. The detection rate of CTA for aneurysms less than 3 mm in diameter was higher than that of MRA. Conclusion. CTA, DSA, and MRA have their own advantages and disadvantages in the diagnosis of cerebral aneurysms. They all have the diagnostic value for aneurysms.
