2021 arXiv   pre-print
Both the 2D and 3D U-Net had the best segmentation performance with Gaussian blur, rotation and flipping compared to other experiments without augmentation or only one of those augmentation techniques.  ...  Accurate cerebral vessel segmentation of Time-of-Flight Magnetic Resonance Angiographs (TOF-MRAs) is an essential step in this process.  ...  For example, the full dataset provided by the Aneurysm Detection And segMentation (ADAM) challenge containing 113 sets of brain MR images for training and 142 sets for testing could be used. 18 Furthermore  ...

2020 arXiv   pre-print
We apply our model to 214 subjects (83 patients, 131 controls) who underwent Time-Of-Flight Magnetic Resonance Angiography (TOF-MRA) and presented a total of 111 unruptured cerebral aneurysms.  ...  In this work, we address the task of brain aneurysm detection as a patch-wise binary classification with weak labels, in contrast to related studies that rather use supervised segmentation methods and  ...  For the former group, patients with one or more unruptured intracranial aneurysms were included, while patients with treated and ruptured aneurysms were excluded.  ...

Modality agnostic intracranial aneurysm detection through supervised vascular surface classification [article]

Žiga Bizjak, Boštjan Likar, Franjo Pernuš, Žiga Špiclin
2020 arXiv   pre-print
Intracranial aneurysms (IAs) are generally asymptomatic and thus often discovered incidentally on angiographic scans like 3D DSA, CTA and MRA.  ...  Experimental results show that proposed approach not only significantly improved detection sensitivity and specificity compared to state-of-the-art intensity based methods, but is also modality agnostic  ...  Experiments & Results Performance of proposed aneurysm detection method was evaluated by comparing the obtained heatmaps to the manual annotation of IAs on the same surface as made by the skilled neurosurgeon  ...

Stent deployment across the aneurysm neck supports the coil mass inside the aneurysmal sac, and furthermore, has an effect on local hemodynamic and biologic changes.  ...  The anterior cerebral artery is a common location of intracranial aneurysms. The standard coil embolization technique is limited by its inability to occlude wide-neck aneurysms.  ...  It is reported that time of flight (TOF) MRA is sufficient and effective to assess re-opening of the coiled aneurysms treated using Enterprise stents, which produce more signal loss than Neuroform stents  ...

The role of MR angiography in the pretreatment assessment of intracranial aneurysms: a comparative study

W M Adams, R D Laitt, A Jackson
2000 American Journal of Neuroradiology  
Our goal was to estimate the clinical efficacy of MR angiography (MRA) in the pretreatment assessment of ruptured and unruptured intracranial aneurysms.  ...  Of the 42 aneurysms examined, 34 were small (<10 mm), six were large (10-25 mm), and two were giant (>25 mm). Three aneurysms were not detected with MRA.  ...  This study was designed to define the value of 3D-TOF MRA for the pretreatment assessment of both ruptured and unruptured cerebral aneurysms.  ...
