Segmentation of Intracranial Vessels and Aneurysms in Phase Contrast Magnetic Resonance Angiography Using Multirange Filters and Local Variances

Abstract: Abstract-Segmentation of intensity varying and low-contrast structures is an extremely challenging and rewarding task. In computer-aided diagnosis of intracranial aneurysms, segmenting the high-intensity major vessels along with the attached lowcontrast aneurysms is essential to the recognition of this lethal vascular disease. It is particularly helpful in performing early and noninvasive diagnosis of intracranial aneurysms using phase contrast magnetic resonance angiographic (PC-MRA) images.

“…Based on the PCA venogram, semi-automated segmentation of major representative veins (superior sagittal sinus (SSS), straight sinus (StrS), transverse sinuses (TraS), and internal cerebral veins (ICVs)) was performed using ITK-SNAP's "active contour segmentation mode" (Bettoni et al, 2018;Law and Chung, 2012). Here, the TraS segment comprised the transverse sinuses, extending into the sigmoid sinuses and the internal jugular veins.…”

“…Therefore, there is a need to enhance these images in order to obtain a good segmentation of the LC beams. Enhancement of curvilinear structures for the purpose of detection or segmentation has been proposed in a number of clinical applications, such as for extracting individual filaments in confocal and total internal reflectance fluorescence (TIRF) microscopy images [41], blood vessel extraction in retinal fundus images [42]–[44], segmentation of intracranial vessels in phase-contrast magnetic resonance angiographic (PC-MRA) images [45], detection and tracking of vehicles in wide area aerial images [46], and neuron detection and segmentation in microscopy images [47]–[49]. In this work, we use the isotropic undecimated wavelet transform (IUWT), which has been used for astronomical [50] and biological [51] applications.…”

“…The results prove that this method is highly sensitive and can potentially assist treating physicians in aSAH by providing automated detection and segmentation of aneurysms. Law et al [ 33 ] proposed a novel intensity-based algorithm to segment intracranial vessels and the attached aneurysms, which can handle the low-contrast aneurysmal regions affected by turbulent flows. It is grounded on multirange filters and local variances to extract intensity-based image features.…”
