“…Volume rendering images of IV 3D DSA were more effective in demonstrating the relationship between the aneurysm and the adjacent vessels than MIP imaging. 6 For examination of the existence of small aneurysms and for analysis of the size of aneurysms and vessels, MIP produced from the original nonthreshold 3D data was feasible. 6 When data were transferred to the personal computer for reconstruction, the matrix size was transformed from 512 ϫ 512 to 256 ϫ 256 by voxel addition.…”

This procedure is necessary for better contrast resolution because the contrast medium is diluted by a much larger volume of blood in IV 3D DSA.…”

“…7 Despite some disadvantages, we think that IV 3D DSA may be more suitable for preoperative study of endovascular treatment than 3D CTA, because the question of whether a working view for endovascular treatment is reproduced on the C-arm can be checked with IV 3D DSA. 6 IV 3D DSA can be performed more quickly and safely than conventional angiography, especially in outpatients, without the risk and cost of arterial catheterization. IV DSA is generally a very safe procedure with low morbidity, 2 but there have been a few descriptions of the extravasation of contrast material during IV DSA because of its high rate of injection.…”

Background: Intracranial aneurysm is a common cerebrovascular disease, which cause wide concern by neurosurgeons. The 3D-DSA images simulated surgical path may improve the success rate of operation in bridging surgery of emergency ruptured intracranial aneurysms. Methods: Eighteen patients with intracranial ruptured aneurysms that underwent craniotomy clipping surgery from January 2015 to January 2016 were included in this study. All patients were diagnosed with ruptured aneurysm and SAH, and 3 of them had concomitant hematoma. All patients were clipped in 3 days after diagnosis. Before clipping, the relevant information and data of the 3D-DSA images simulated surgical path were observed to guide intracranial aneurysm clipping surgery. Results: According to the information of the 3D-DSA images simulated surgical path, all aneurysms were clipped successfully. 1 patient died of vessel spasm, and the remaining patients recovered well.

“…Compared with conventional two‐dimensional (2D) digital subtraction angiography, 3D CBRA provides more detailed information for the assessment of cerebral aneurysms and allows more exact depiction of anatomic details that are beneficial for interventional surgery 2 , 3 , 4 , 5 , 6 . Regarding the effective dose to the patient Bridcut et al (7) reported a mean total effective dose of 3.4 mSv for the assessment of aneurysms in a conventional coiling procedure.…”

The assessment of intracranial aneurysms is increasingly performed using three‐dimensional cone‐beam rotational angiography (3D CBRA). To reduce the dose to the patient during 3D CBRA procedures, filtered region‐of‐interest imaging (FROI) is presented in literature to be an effective technique as the dose in regions of low interest is reduced, while high image quality is preserved in the ROI. The purpose of this study was to quantify the benefit of FROI imaging during a typical 3D CBRA procedure in a patient's head region. A cone‐beam rotational angiography unit (Infinix) was modeled in GMctdospp, an EGSnrc‐based Monte Carlo software, which calculates patient dose distributions in rotational computed tomography. Kodak Lanex, a gadolinium compound, was chosen to be the ROI filter material. The adult female ICRP reference phantom was integrated in GMctdospp to calculate organ and effective doses in simulations of FROI‐CBRA examinations. During the Monte Carlo simulations, different parameters as the ROI filter thickness, the ROI opening size, the tube voltage, and the isocenter position were varied. The results showed that the reduction in dose clearly depends on these parameters. Comparing the reduction in organ dose in standard 3D CBRA and FROI‐CBRA, a maximum reduction of about 60%–80% could be achieved with a small sized ROI filter and about 40%–70% of the dose could be saved using a ROI filter with a large opening. Further we could show that dose reduction strongly depends on filter thickness, the location of the organ in the radiated area, and the position of the isocenter. As a consequence, dose reduction partially differs from theoretically calculated values by a factor up to 1.6. The effective dose could be reduced to a minimum of about 40%. Due to the fact that standard 3D CBRA is only used for the assessment of aneurysms at present and, thus, most of the patient dose originates from the aneurysm treatment (with 2D techniques) itself, the dose reduction effect of ROI filtering in 3D CBRA tends to be much smaller, if the patient dose of a whole aneurysm treatment procedure is considered.PACS numbers: 87.59.DJ, 87.55.kh
