A puncturing device that can be observed by means of tomography, such as MRI, which can be operated simply, safely and reliably. One embodiment of the invention includes a cuboid body containing a needle guide, which extends to a base area of the cuboid body. The base area is configured for placement on the skin of a patient. Marker bores disposed in the cuboid body and containing a contrast medium make it possible to precisely align the needle guide with a tomography picture plane in that the images of the bores have to assume a particular mutual configuration on a monitor. This allows a puncture needle used with the needle guide to be observed along its entire path on tomograms.
