Cerebral computed tomography perfusion at the bedside using a portable CT scanner: report of two cases

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...
