“…New technical adjustments have led to an improvement in the ability of SWI, not only for detection of hemorrhage but also in the differentiation between blood and calcium, that commonly coexist at VMs 50,51 . For this aim, magnitude and phase images are derived from the same SWI acquisition 52 . Both calcium and blood appear as hypointense lesions on magnitude SWI; however, due to their different nature, on right‐handed systems, calcium (diamagnetic) will show a positive phase (bright appearance) and blood (paramagnetic) a negative phase (dark appearance).…”

Vascular malformations (VMs) of the central nervous system (CNS) include a wide range of pathological conditions related to intra and extracranial vessel abnormalities. Although some VMs show typical neuroimaging features, other VMs share and overlap pathological and neuroimaging features that hinder an accurate differentiation between them. Hence, it is not uncommon to misclassify different types of VMs under the general heading of arteriovenous malformations. Thorough knowledge of the imaging findings of each type of VM is mandatory to avoid these inaccuracies. Conventional MRI sequences, including MR angiography, have allowed the evaluation of CNS VMs without using ionizing radiation. Newer MRI techniques, such as susceptibility‐weighted imaging, black blood sequences, arterial spin labeling, and 4D flow imaging, have an added value of providing physiopathological data in real time regarding the hemodynamics of VMs. Beyond MR images, new insights using 3D printed models are being incorporated as part of the armamentarium for a noninvasive evaluation of VMs. In this paper, we briefly review the pathophysiology of CNS VMs, focusing on the MRI findings that may be helpful to differentiate them. We discuss the role of each conventional and advanced MRI sequence for VMs assessment and provide some insights about the value of structured reports of 3D printing to evaluate VMs.

We present the application of 3-dimensional susceptibility-weighted imaging (SWI) technique for evaluation of pathologies of the spine and spinal cord. This work focuses on the advantage of this imaging technique as an adjunct to the conventional imaging to evaluate various disorders of the spine and spinal cord like trauma, degenerative diseases, vascular malformations, and tumours, where SWI may offer valuable harmonizing evidence that may be helpful in the diagnosis and management of the patients with these pathologies.

Susceptibility Weighted With Quantitative Phase Magnetic Resonance Imaging in Differentiation of Various Stages of Hemorrhage and Calcification in Female Pelvic Pathologies: A Preliminary Study

Abstract: Quantitative phase imaging has the potential to differentiate various stages of hemorrhagic and calcified pathologies. This may add value to the conventional MRI in improved characterization of these entities in female pelvic pathologies.
