Evaluation of angiographic computed tomography in the follow-up after endovascular treatment of cerebral aneurysms—a comparative study with DSA and TOF-MRA

Feasibility of Angiographic CT in Peri-Interventional Diagnostic Imaging: A Comparative Study with Multidetector CT

“…All these technical aspects of ACT make it an application of potentially great importance during or after neurointerventional procedures. [8][9][10] In our study, we included 84 ACTs acquired on a biplane angiography scanner, during or immediately after a neuroendovascular procedure, in the period of 2006 -2009. The purpose of our study was to evaluate the feasibility and diagnostic value of ACT in peri-interventional imaging and, particularly, in the detection and progress of hemorrhage or hydrocephalus.…”

Mid-Term Outcome Following Pipeline Embolization of Unruptured Intracranial Aneurysms

“…DSA is the gold standard for follow-up of UIAs after endovascular treatment (20). CT angiography and MR angiography can be utilized, however both are inferior to DSA for detection of residue or recurrence of the aneurysm (21).…”

Artifact Reduction of Different Metallic Implants in Flat Detector C-Arm CT

“…These images can identify the relationship of the metal implants and provide early recognition of rebleeding or intracranial procedure-related complications, such as incomplete stent deployment, stent migration, stent fracture, or coil dislocation. [12][13][14] However, the metallic artifacts stemming from metal objects hinder clear visualization of a hematoma or parenchyma surrounding metal objects. 14 Prell et al 15 demonstrated successfully reducing metal artifacts by using their version of a MAR algorithm in a small series of 7 patients who had cerebral aneurysms and were treated with coiling or clipping.…”
