“…They include FLAIR, echo-planar T2*weighted susceptibility-weighted imaging and diffusionweighted images. [23][24][25] The ASL-MRP technique operates on the principles of subtracting a 'tag' image acquired through magnetic labelling of blood from a 'control' or 'reference' image obtained without labelling. This approach involves labelling the magnetisation of water protons in the blood using methods such as inversion at the major feeding arteries.…”

Abstract Background: Early diagnosis of cerebral venous thrombosis (CVT) is crucial for a favourable prognosis as CVT can lead to severe outcomes. However, certain scenarios, such as during pregnancy, restrict the use of contrast agents, thus rendering conventional magnetic resonance imaging (MRI) methods insufficient for accurate diagnosis. In light of these challenges, our study endeavours to assess the diagnostic potential of the arterial spin labelling magnetic resonance perfusion (ASL-MRP) technique, a contrast-agent–free approach, in the context of CVT diagnosis. Materials and Methods: Between 1 March 2022 and 30 May 2022, patients diagnosed with CVT via contrast-enhanced MR venography in the neurology clinic of our hospital were evaluated through ASL-MRP. Patient-specific demographics, including age, gender, presenting symptoms, underlying causes, impacted cortical sinus structures and MRI findings, were documented. Within the framework of ASL-MRP, an elevation in cerebral blood flow (CBF) detected within the affected sinus and/or neighbouring structures was deemed indicative of pathological conditions. Results: Among the 13 patients included in our study, six were diagnosed with acute CVT, whereas seven were diagnosed with chronic CVT. The assessment of CBF using ASL-MRP revealed CBF elevation in five out of the six cases (83.3%) exhibiting acute CVT. However, no anomalous findings were observed in the ASL-MRP scans of patients presenting with chronic CVT. Discussion: The utilisation of ASL-MRP eliminates the need for contrast agent administration. It is a promising technique in facilitating the diagnosis of acute CVT and distinguishing it from chronic CVT cases.
