title: [Dynamic contrast-enhanced brain perfusion imaging: Technique, pitfalls and problems].
abstract: Conventional magnetic resonance and computed tomography imaging, despite their sensitivity in delineating tissue anatomy and detecting head and neck pathology, are nonspecific in their ability to physiologically characterize abnormal tissue. The perfusion imaging attempts to measure the steady-state delivery of blood to a given parenchymal region. In this article, the technique of magnetic resonance perfusion and computed tomographic perfusion is discussed in addition to the pitfalls and problems in the light of the latest literature and our own experience.
