Review Comparative Study
[Uterine fibroids--therapy from the point of view of the gynaecologist].
Uterine fibroids are the most common benign tumour affecting the female reproductive tract, 20% of all women older than 35 years are afflicted. Patients with fibroids tend to be asymptomatic, but fibroids may lead to meno-, metrorrhagia, hyper- and dysmenorrhoea and urination and defecation problems. If the fibroids do not cause any clinical symptoms and if there is no suspicion of a malignant tumor, there is no need for therapeutic intervention. ⋯ For women who wish to conserve their fertility enucleation of the fibroids can be considered. These surgical procedures can be performed endoscopically or abdominally. Uterine artery embolisation, a radiological intervention, is less invasive and represents an interesting therapeutic alternative.

Comparative Study
[Computed tomography and magnetic resonance imaging of congenital abnormalities of the temporal bone].
Congenital abnormalities of the temporal bone are mostly accompanied by conductive or sensori-neural hearing loss. Before any therapeutic procedures are done high resolution CT (HRCT) and magnetic resonance imaging (MRI) should be performed to establish the correct diagnosis and to plan the potentially surgical intervention. HRCT best depicts osseous changes especially those of the external auditory canal and the middle ear containing the ossicles and the osseous structures of the temporal bone and the petrous bone containing the inner ear. ⋯ These syndromes may be accompanied by certain malformations of the temporal bone. HRCT and MRI are both excellent methods to depict congenital abnormalities of the temporal bone and of the inner ear and should be used as complementary methods because HRCT best depicts osseous changes and MRI superbly depicts soft tissue changes. Both methods are important to establish the correct diagnosis to plan the therapeutic procedures.

Randomized Controlled Trial Comparative Study Clinical Trial
[Multiphasic MR angiography as an intra-individual comparison between the contrast agents Gd-DTPA, Gd-BOPTA, and Gd-BT-DO3A].
The availability of new MR contrast agents having either a protein binding effect or higher concentration leads to the question if they differ from standard compounds in their vascular contrasting properties. ⋯ Gadobenate dimeglumine was shown to be a favorable contrast agent for multi-phasic MRA. A higher concentrated Gd-chelate does not automatically lead to improved vascular contrast if standard imaging protocols are used.
