“…Cranial imaging is useful to assess additional features of aseptic meningitis or vasculopathy. [ 35 ] Orbital sarcoidosis is more likely to spread along the ON, while NSOID spreads along the SOF. Sarcoidosis is more commonly associated with scleritis and tends to involve the anteroinferior quadrant.…”

In this article we focus on a systematic approach to assess common orbital lesions on magnetic resonance imaging (MRI). The identification of the probable compartment or structure of origin helps narrow the differential diagnosis of a lesion. Analyzing the morphology, appearance, and signal intensity on various sequences, the pattern, and degree of contrast enhancement are key to characterize lesions on MRI. Imaging features suggesting cellularity and vascularity can also be determined to help plan for biopsy or surgery of these lesions. MRI can also distinguish active from chronic disease in certain pathologies and aids in selecting appropriate medical management. MRI may thus serve as a diagnostic tool and help in guiding therapeutic strategies and posttreatment follow-up.

“…Intracranial VW-MR is a valuable diagnostic adjunct to conventional angiographic imaging to help distinguish intracranial vasculopathies. Studies report on its use for identifying cerebral vasculitis, reversible cerebral vasoconstriction syndrome (RCVS), arterial dissection, and ICAD (13,17,(28)(29)(30)(31)(32). These studies describe imaging features of the vessel wall that improve the specificity of conventional angiographic imaging.…”

Intracranial atherosclerotic disease (ICAD) is one of the most common causes of ischemic stroke worldwide. Along with high recurrent stroke risk from ICAD, its association with cognitive decline and dementia leads to a substantial decrease in quality of life and a high economic burden. Atherosclerotic lesions can range from slight wall thickening with plaques that are angiographically occult to severely stenotic lesions. Recent advances in intracranial high resolution vessel wall MR (VW-MR) imaging have enabled imaging beyond the lumen to characterize the vessel wall and its pathology. This technique has opened new avenues of research for identifying vulnerable plaque in the setting of acute ischemic stroke as well as assessing ICAD burden and its associations with its sequela, such as dementia. We now understand more about the intracranial arterial wall, its ability to remodel with disease and how we can use VW-MR to identify angiographically occult lesions and assess medical treatment responses, for example, to statin therapy. Our growing understanding of ICAD with intracranial VW-MR imaging can profoundly impact diagnosis, therapy, and prognosis for ischemic stroke with the possibility of lesion-based risk models to tailor and personalize treatment. In this review, we discuss the advantages of intracranial VW-MR imaging for ICAD, the potential of bioimaging markers to identify vulnerable intracranial plaque, and future directions of artificial intelligence and its utility for lesion scoring and assessment.

“…77 Interestingly, high-resolution vessel wall imaging has shown a strong association between ruptured aneurysms and circumferential aneurysm wall enhancement in subarachnoid hemorrhage (SAH), which may identify the site of rupture in patients with multiple intracranial aneurysms. [79][80][81][82] In addition, circumferential wall enhancement has been more frequently observed in unruptured but unstable (growing and symptomatic) aneurysms. 80,81 Although a minority of incidentally discovered aneurysms also show wall enhancement, it still needs to be established if these are at an increased risk of rupture.…”

An additional advantage of 7T is the relative ease with which CSF suppression is achieved, something that has not been matched at 3T yet. Finally, high SNRs and CNRs of 7T MRI enable more detailed assessment of other neurological pathology like (micro)infarcts and (micro)bleeds, which together with highly detailed vessel wall MR imaging might provide information on the cerebrovascular status of the individual patient. 27,28 However, the question remains whether these advantages have additional clinical value over data acquired at 3T.Nevertheless, for all its advantages, a major drawback of 7T MRI is that these platforms are only sparsely available, which makes widespread implementation of 7T MRI sequences in clinical practice currently impossible. Therefore, it is important that technical advancements and newly acquired insights can be translated back 14 CHAPTER 1 This ThesisThis thesis will address several of the current caveats in both implementation of intracranial vessel wall MRI sequences and clinical interpretation of imaging transition from research-based knowledge towards a radiological and clinically applicable imaging technique, both at 3T and 7T MRI.
