Title : Multidetector CT angiography for the detection of lenticulostriate and anterior choroidal arteries


Background: Multidetector CT angiography (MDCTA) is widely used for the detection of large vessel occlusion in acute ischaemic stroke. This modality has not been used in the assessment of lenticulostriate (LSA) or anterior choroidal artery (AChA) occlusion that results in basal ganglia infarcts. Recent advances in MDCTA technology enable the detection of sub-millimeter vessels with targeted maximum intensity projection images (MIP) and source images. Our study assessed the detection rate of LSA and AChA using MDCTA. 

Method: Ischaemic stroke patients with admission 64 or 128-slice MDCTA and no infarct on follow-up MRI were included. Dedicated MIP reconstructions of the MDCTA in the plane of the LSA and AChA were created. The LSA and/or AChA were deemed “detected” if both readers visualized the vessel and could trace the origin to the middle cerebral or internal carotid arteries. 

Results: Twenty-one patients met all inclusion criteria (median age, 63; range 46–85; 11 females). The right LSA was detected in 14% (n=3), the left LSA in 19% (n=4), the right AChA in 14% (n=3), and the left AChA in 10% (n=2) cases. The mean diameter of these vessels visualized was 0.6mm (range 0.1–1.4mm). 

Conclusion: The lenticulostriate and anterior choroidal arteries can only be detected in a small proportion of ischaemic stroke patients. Current MDCTA is unlikely to allow reliable detection of occlusion of these arteries in stroke patients.
