Sommario/riassunto |
|
The algebraic theory of corner subrings introduced by Lam (as an abstraction of the properties of Peirce corners eRe of a ring R associated with an idempotent e in R) is investigated here in the context of Banach and C*-algebras. We propose a general algebraic approach which includes the notion of ranges of (completely) contractive conditional expectations on C*-algebras and on ternary rings of operators, and we investigate when topological properties are consequences of the algebraic assumpt... |

Sommario/riassunto |

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. |
