Brain Perfusion SPECT in Patients with PHACES Syndrome Under Propranolol Treatment

Abstract

Propranolol treatment was safe in our patients who did not show signs of perfusion changes. The high sensitivity for detecting functional impairment makes brain perfusion SPECT useful in the diagnosis and follow-up of patients with PS considered at risk of neurovascular impairment. Accurate knowledge of its pathophysiological basis, together with the appropriate technique and careful interpretation of reporting, will enhance the clinical use of brain SPECT in those patients.
