Clinical Trial
[MRI-guided percutaneous radiofrequency ablation of hepatic neoplasms--first technical and clinical experiences].
To evaluate the safety and efficacy of MR-guided radiofrequency ablation (RFA) of hepatic neoplasms. ⋯ MR-guided RFA using single cooled tip electrodes is safe and technically effective for treatment of hepatic neoplasms up to 3 cm in size, however further improvements are necessary.

Analysis of the morphological characteristics of pulmonary mucormycosis using computed tomography (CT). ⋯ Computed tomography allows an improved diagnosis and therapeutic follow-up in patients suffering from pulmonary mucormycosis.

Comparative Study
[The radiation risks from x-ray studies for age assessment in criminal proceedings].
Age estimation for forensic purposes is, in general, based on a radiogram of the left hand or an orthopantomogram of the teeth. Two examples are given exemplifying the principal procedure that may be applied for estimating the radiation risks associated with the radiological examinations considered. ⋯ The calculated radiation risks are of a similar order of magnitude as are the risks the respective person is exposed to on the way to the medical examination or to the court. However, the applicability and the limits of the radiological procedures applied for age estimation require extensive and critical discussion.

Comparative Study
[Hypothenar hammer syndrome: causes, sequelae and diagnostic aspects].
To investigate the reasons and disease course of Hypothenar Hammer Syndrome. ⋯ An exact investigation concerning the pathogenesis of HHS is a precondition for treating the disease and may help to establish HHS as an occupational disease. MR-angiography may be a new approach for assessing HHS.

Comparative Study
[Diagnosis of tracheal instability: spiral CT in inspiratory and expiratory and respiratory cine CT].
In tracheo- and bronchomalacia, localization and determination of collapse is necessary for planning a surgical procedure. We compared inspiratory and spiral CT, cine CT, and bronchoscopy and evaluated the relevance of each method. ⋯ Paired inspiratory and expiratory spiral CT localizes tracheal stenoses and demonstrates clinically relevant extraluminal compression. Improved evaluation of expiratory collapse and further information of localized tracheal instability is provided by cine CT.
