This book presents numerous figures of various variations of the supraaortic arteries detected by MR and CT angiography. Improved both MR and CT angiographic image quality permits incidental detection of even small anomalous arterial branches. Although the cerebral arterial variations may have limited clinical significance, their correct diagnosis during MR and CT angiographic image interpretation is important to interventional neuroradiologists as well as both neurosurgeons and otorhinolaryngologists, who must be familiar with arterial variations to prevent complications during surgery. Readers can easily identify arterial variations and make correct diagnosis during image interpretation using this textbook.
