1. An instrument configured for insertion into a vessel, the instrument comprising:
a pressure sensor integrated into the instrument, the pressure sensor configured to provide temporal pressure measurement signals of pulsatile blood motion within the vessel; and
a flow sensor integrated into the instrument, the flow sensor configured to provide temporal flow measurement signals of the pulsatile blood motion within the vessel,
wherein the pressure sensor and the flow sensor are arranged on the instrument to provide the temporal pressure measurement signals and the temporal flow measurement signals in a same transversal plane of the instrument, and
wherein the instrument is connectable to a processor configured to detect a condition of a segment of the vessel by determination of a phase difference between the temporal pressure measurement signals and the temporal flow measurement signals.
