MRI of the Head and Neck: Functional Anatomy Clinical Findings Pathology I [Paperback]

Since the establishment of magnetic resonance imaging theclinical diagnostic of the head and neck has improvedsubstantially and, therefore, in many cases this techniqueis used in the first place of radiological diagnosis. Thefeasibility of non-invasive MR angiography and 3-dimensionalreconstruction has enlarged the indication field of MRI.This book presents the meaning of this imaging technique forthe diagnosis of diseases in head and neck. Excellentfigures show the technicaland diagnostical possibilities ofthis method, the advantages and limitations of which areexplained as well. A comprehensive diagnostic strategy foreach diagnostic region is presented. This book is disignedfor the use of especially radiologists, ENT specialists andsurgeins.1 Introduction.- 1.1 The Problem and the Goal.- 1.2 Clinical Presentation.- 1.3 Imaging Modalities in the Head and Neck.- 1.4 Methods of Treatment.- 2 Basics of Magnetic Resonance Imaging.- 2.1 Principles of Magnetic Resonance.- 2.2 Parameters of MRI.- 2.3 Equipment.- 2.4 Pulse Sequences and Special Techniques.- 2.5 Biologic Effects and Safety Considerations.- 3 Examination Technique.- 3.1 Coil Technology.- 3.2 Sequences and Specific Examination Protocols.- 3.3 Fast Sequences and Dynamic MRI.- 4 Contrast Media.- 4.1 Basic Principles.- 4.2 Pharmacology of Gd-DTPA.- 4.3 Safety Profile of Gd-DTPA.- 4.4 Examination Protocols.- 4.5 Clinical Indications.- 4.6 Summary.- 5 Signal Intensity and Relaxation.- 5.1 In Vivo Results.- 6 Temporal Bone, Middle Skull Base, and Cerebellopontine Angle.- 6.1 Clinical Findings.- 6.2 Examination Technique.- 6.3 The Topographic Basis for the Evaluation of MR Images.- 6.4 Sensitivity and Specificity of MRI in Relation to Other Imaging Modalities.- 6.5 Acoustic Neuroma.- 6.6 Other Neuromas.- 6.7 Glomus Tumors.- 6.8 Meningioma.- 6.9 Epidermoid.- 6.10 Cholesteatoma and Other Tumors of the Pyramid Apex.- 6.11 Tumors of the Postelƒ5
