Prompt and accurate diagnosis is the foundation of acute ischaemic stroke care. Multiple positive endovascular thrombectomy trials in ischaemic stroke patients with large vessel occlusions have further emphasised this but also added complexity to treatment decisions. CT angiography is now routine for patients who present with an acute stroke syndrome around the world. Members of the neurology and stroke teams (rather than radiologists) are often the first doctors to lay eyes on the CT images and are best equipped to integrate the clinical picture with the imaging findings. A sound understanding of acute stroke imaging is therefore essential for clinicians who work with acute stroke patients. This review describes some pearls we have gleaned from our own experience in acute stroke imaging as well as some potential follies to be avoided.
