A medical guide ( 1, 15 ) is provided for guiding a medical instrument into a target site within a patient's body, for use in connection with a cross-sectional imaging technique such as magnetic resonance imaging or computed tomography. The medical guide comprises a base ( 2, 16 ) adapted to be positioned on the patient's body, a trajectory guide ( 5, 17 ) movably connected to the base, wherein the trajectory guide is provided with at least one distal marker ( 7, 22 ) and at least one proximal marker ( 8, 23 ) visible by said cross-sectional imaging technique, and the markers are separated by at least one portion not visible in a chosen cross-sectional imaging technique. Furthermore, the alignment markers are placed so as to optimize the trajectory path and facilitate the procedure of e.g. taking a biopsy sample using the selected cross-sectional imaging technique.
