Spinal haematoma is a rare occurrence, however has the potential to cause significant spinal injury and morbidity. MRI is the gold-standard of investigation, and urgent imaging is required for early diagnosis and treatment to ensure best patient outcomes. We present a pictorial review demonstrating the imaging features of spinal haematoma based on meningeal space assignment; epidural, subdural, subarachnoid, intramedullary and a combination of these locations. In this review, we summarise the literature and imaging findings of spinal haematoma on MRI. Particular imaging features which help to differentiate between haematoma in the different spinal meningeal compartments are discussed below.
The delayed vessel sign is a reliable indicator of anterior circulation vessel occlusion, particularly in cases involving distal branches. Assessment of the later phases of multiphase CTA for the delayed vessel sign leads to a significant improvement in the speed and confidence of interpretation, compared with single-phase CTA.
This study demonstrated a subjectively improved experience of MRI for some patients with the intervention of sound and smell. The study failed to show a significant decrease in patient movement during MRI investigations. This may relate to the small study size and a low level of patient movement in the case group. Advances in knowledge: Sound and olfactory sensory environment interventions at MRI can improve the patient experience. These low-cost interventions are well tolerated, may improve acceptance of MRI in patients with anxiety and offer a competitive advantage to imaging centres.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
