[en] Conventional radiographs have been shown suitable to survey rheumatic lesions and document them in a standardized form. This technique, however, is limited to advanced stages of the disease with bone and joint destruction. In early arthritis, the quantification of inflammatory activity and recently also healing processes are better documented with MRI or ultrasound. As a result, finding low-grade abnormalities and tissue repair is gaining increasing importance in diagnostic imaging. (orig.)

[en] In the inner and middle ear, subtle anatomical structures are located closely together and therefore can be identified only by a trained examiner. In addition to a detailed description of the inner and middle ear anatomy, the article presents the clinical relationship to diseases and discusses the value of CT and MR in respect to the anatomical location. (orig.)

[en] High-resolution cross-section imaging modalities, i.e., CT and MRI, are the methods of choice for detailed assessment of the petrous bone. The decision what modality to choose is based upon the clinical history, the patient's ENT status and the clinically suspected pathology. The radiologist should be familiar with common diseases of the petrous bone as well as with important clinical findings. The following article focusses on the most common indications for petrous bone imaging and uses selected case studies to correlate clinical and radiological findings. (orig.)

[en] This contribution demonstrates why MRI has become the most effective imaging method for clarifying knee disorders after conventional radiography. A presentation of the examination protocols is followed by a discussion of the most important pathologies and their manifestations in MRI including relevant MRI anatomy. Normal variants and pitfalls are described to avoid misdiagnoses. A special chapter is dedicated to postsurgical MRI findings. (orig.)
