“…However, unlike in DSA, in cone-beam CT, the skin dose of radiation is distributed over 180° of the body being imaged because of the rotational nature of the acquisition (17,18). Moreover, a single cone-beam CT examination can yield the same information as multiple DSA acquisitions in technically challenging cases, and may, therefore, reduce the total amount of radiation exposure, procedural time, and contrast medium use (19,21).…”

Purpose:To describe findings in prostatic arteries (PAs) at digital subtraction angiography (DSA) and cone-beam computed tomography (CT) that allow identification of benign prostatic hyperplasia and to determine the value added with the use of cone-beam CT. Materials and Methods:This retrospective single-institution study was approved by the institutional review board, and the requirement for written informed consent was waived. From February 2009 to December 2014, a total of 148 patients (mean age 6 standard deviation, 70.5 years 6 14.5) underwent DSA of the internal iliac arteries and cone-beam CT with a flat-detector angiographic system before they underwent prostate artery embolization. Both the DSA and conebeam CT images were evaluated by two interventional radiologists to determine the number of independent PAs and their origins and anastomoses with adjacent arteries. The exact McNemar test was used to compare the detection rate of the PAs and the anastomoses with DSA and with cone-beam CT. Results:The PA anatomy was evaluated successfully by means of cone-beam CT in conjunction with DSA in all patients. Of the 296 pelvic sides, 274 (92.6%) had only one PA. The most frequent PA origin was the common glutealpudendal trunk with the superior vesicular artery in 118 (37.1%), followed by the anterior division of the internal iliac artery in 99 (31.1%), and the internal pudendal artery in 77 (24.2%) pelvic sides. In 67 (22.6%) pelvic sides, anastomoses to adjacent arteries were documented. Conclusion:Cone-beam CT is a useful adjunctive technique to DSA for identification of the PA anatomy and provides information to help treatment planning during prostatic arterial embolization.q RSNA, 2016

“…Authors of several studies (16)(17)(18)(19) have shown that the use of cone-beam CT could be extremely helpful during transcatheter arterial chemoembolization, especially in cases of complex hepatic arterial anatomy. However, to our knowledge, studies of the use of cone-beam CT to evaluate the PA anatomy are limited (15,20,21 …”

“…This imaging technique provides cross sectional, soft-tissue, CT-like images without the need to move the patient to a CT room and offers many advantages over classic 2D angiography alone 15 , 17 , 19 , 32 . First, CBCT detection accuracy of HCC lesions is equivalent to multidetector CT and MRI and superior to 2D angiography 15 , 17 , 19 . Second, it is the most accurate imaging technique to identify tumor-feeding arteries 14 .…”

“…Cone-beam CT (CBCT) is a novel technique that is increasingly used during TACE for inoperable HCC 15 - 20 . This imaging technique uses a flat-panel detector angiographic system to produce CT-like soft-tissue images without the need to transfer the patient to a CT unit 15 , 17 , 19 . It can be used to visualize tumor-feeding vessels and parenchymal stain during TACE, achieving detection accuracies significantly superior to standard 2D angiography 17 …”

BackgroundThe purpose of this retrospective study was to evaluate treatment response, adverse events and survival rates of patients with intermediate stage HCC treated with superselective doxorubicin-loaded DC Bead transarterial chemoembolization (DEBDOX) under cone beam computed tomography (CBCT) control.Patients and methodsBetween October 2010 and June 2012, 35 consecutive patients with intermediate stage HCC (32 male, 3 female; average age, 67.5 ± 7.8 years; 22 patients Child-Pugh class A, 8 class B, 5 without cirrhosis) were treated with DEBDOX TACE. Portal vein thrombosis was observed in 6 (17.1%) patients. DEBDOX TACE was performed by superselective catheterization of feeding vessels followed by embolization with 100-300 μm microspheres loaded with 50-100 mg of doxorubicin. In all cases, CBCT was used during chemoembolization. Tumor response rates were defined according to mRECIST criteria.ResultsOverall, 120 procedures were performed (mean, 3.2 per patients). We treated 97 lesions with an average diameter of 4.9 ± 1.9 cm. There were 32 minor and 2 (1.6%) major complications (one liver abscess and one cerebrovascular insult). After a mean follow-up of 27.7 ± 10.5 months, 94.3% of patients achieved an objective response to treatment (42.4% complete response and 57.6% partial response). Mean time to progression was 10.9 ± 5.3 months. Mean overall survival was 33.9 months (95% CI; 28.9 – 38.9 months), with 1- and 2- year survival of 97.1% and 65.7%, respectively.ConclusionsSuperselective DEBDOX TACE performed under CBCT control is a safe and effective method with high rates of tumor response and overall survival.

“…In this context, MIP, MPR and SSD images reconstruction (Figs. 4 and 5) are an indispensable tool which allows multidetecor CTA to provide specific and precise measurements of anterograde or retrograde extent of dissection, including length, diameter of the aorta and the true and false lumens, involvement of vital vasculature, and distance from the intimal tear to the vital vascular branches [3,7,35].…”
