A comparison between the CS-TOF and the CTA/DSA for WEB device management

Dr. Algin and his team’s new study has been published.
The results of a recent study conducted by Prof. Dr. Oktay ALGIN and the scientists they worked with were published in the scientific journal “Interventional Neuroradiology”.
In the study named “A comparison between the CS-TOF and the CTA / DSA for WEB device management”; It was determined that the non-contrast and rapid cerebral vascular imaging technique (TOF-MRA) was effective and sufficient both in detecting/management cerebral aneurysms and in follow-up after the treatment. Although this technique has many advantages over other brain angiography techniques, the development process continues. 

In ongoing studies, the benefits of the same technique in other cerebrovascular diseases being researched by Dr. Algin and collegues.

There is no study on the role of three-dimensional compressed sensing time of flight MR angiography (3D-CS-TOF) in the management of the WEB device. We evaluated the efficacy of 3-tesla 3D-CS-TOF for the management and follow-up of the WEB device implantations.

Materials and methods

Seventy-three aneurysms of 69 patients treated with the WEB device were retrospectively examined. Morphological parameters and embolization results of the aneurysms were assessed and compared on 3D-CS-TOF, CTA, and DSA images.


Occluded, neck remnant, and recurrent aneurysms were observed in 61 (83.6%), 7 (9.6%), and 5 (6.8%) aneurysms, respectively. Inter- and intra-reader agreement values related to aneurysm size measurements were perfect. Aneurysms size, age, and proximal vessel tortuosity were negatively correlated with the visibility of the aneurysms and parent vessels on 3D-CS-TOF images (p = 0.043; p = 0.032; p < 0.001, respectively). Subarachnoid hemorrhage and age are associated with 3D-CS-TOF artifacts (p = 0.031; p = 0.005, respectively). 3D-CS-TOF findings are in perfect agreement with DSA or CT angiography (CTA) results (p < 0.001).


According to our results, 3D-CS-TOF can be an easy, fast, and reliable alternative for the management or follow-up of WEB assisted embolization.
