Dear Sirs,

Patients with symptoms of acute cerebral infarction require prompt diagnostic evaluation in order to determine appropriate treatment. In cases of ongoing ischemia, computed tomography perfusion (CTP) can be a useful adjunct to non-contrast CT and computed tomography angiography (CTA) for evaluation of tissue at risk [1, 2]. Traditionally, obtaining a CTP study has required transporting the patient from the ER or inpatient setting to the radiology department for a scan on a conventional fixed CT scanner. Often, patients with acute strokes are unstable, and transporting them away from the ICU can pose unnecessary health risks. With the development of a portable head and neck CT scanner, bedside head CT has become a common practice in critically ill patients and has been shown to be a feasible, safe and reliable technique, providing adequate radiological quality for diagnostic decisions [3, 4, 5]. Computed tomography angiography and perfusion can also be obtained efficiently...
