[Influence of sequence type on the extent of the susceptibility artifact in MRI--a shoulder specimen study after suture anchor repair].

Purpose: To compare the extent of susceptibility artifacts after metallic suture anchor implantation by analyzing 14 different MRI sequences.

Materials And Methods: A metallic suture anchor was implanted in the central area of three glenoid porcine specimens. The specimens were imaged with a 1.

[Diagnosis and classification of calcaneal fractures in computed tomography].

Purpose: To compare image quality of single-slice spiral CT (SSCT) and multislice spiral CT (MSCT) in the diagnosis and classification of calcaneal fractures and to present a rapid and precise algorithm for the classification system of Stuermer.

Materials And Methods: In 102 patients with 124 calcaneal fractures, spiral CT was performed, in 82 cases as SSCT with a slice thickness (SD) of 3 mm, a table speed (TS) of 3 - 4 mm/rot and an increment of 1.5 mm.

[Indirect MR-arthrography of the shoulder-value in the detection of SLAP-lesions].

Purpose: A prospective study to assess the value of indirect magnetic resonance-arthrography (MR-Arthro) in the detection of lesions of the superior labrum (SLAP-lesions).

Materials And Methods: Unenhanced magnetic resonance imaging (MRI) and indirect MR-Arthro of the shoulder were performed in 35 patients (9 females and 26 males) with a history of acute or chronic shoulder disorder. The images of unenhanced MRI and indirect MR-Arthro were analyzed independently from each other for the occurrence of SLAP-lesions and the findings correlated with the arthroscopic results.

[Indirect MR Arthrography of the wrist in the diagnosis of TFCC-Lesions].

Purpose: The objective of this prospective study was to assess the value of the indirect MR arthrography (MR-AR) of the wrist in the detection of lesions of the TFCC.

Material And Methods: Indirect MR-AR was performed in 45 patients (23 f/22 m) with unclear ulnar wrist pain. After i.
