To analyse the use of transcatheter embolisation. ⋯ Transcatheter embolisation is an effective tool in the treatment of life-threatening head and neck bleedings.

Case Reports Comparative Study
[CT and PRI angiographic findings in dissection of the neck arteries].
To determine the usefulness of CT angiography (CTA) and MR angiography (MRA) for evaluation of dissection in cervical vessels. ⋯ CT and MR angiography was successful for detection of typical morphology of dissection in all cases. If results in a greater number can be obtained it seems to be conceivable that both methods can be used in primary diagnosis.

We report on our first experience in imaging the cerebral veins and sinuses with CT angiography (CTA). ⋯ CTA is a suitable noninvasive method to study cerebral veins as it is superior to conventional CT because of high resolution and intravascular contrast. To assess the sensitivity of CTA for diagnosis of venous sinus thrombosis a prospective study is needed.

Comparative Study
[Epidurography: comparison with CT, spiral CT and MR epidurography].
The purpose of this study was to explain the origin of image patterns demonstrated by conventional epidurography, which is a controversially discussed topic in recent literature. ⋯ CT epidurography is well suited for obtaining new insights into the interpretation of findings obtained by conventional epidurography.

To evaluate the value of rapid T2-weighted turbo-spin sequences (TSE), turbo-spin-echo sequences with shortened echo spacing (UTSE), gradient-and-spin-echo sequences (GraSE) and T1-weighted echo-planar imaging (EPI) in comparison with conventional spin-echo sequences (SE) in the diagnosis of focal liver lesions. ⋯ Turbo-spin-echo sequences with shortened echo spacing yield a shorter imaging time and improved image quality without loss of signal intensity in tumor/liver-CNR, compared with conventional T2-pulse sequences in liver imaging at 1.OT.
