Abstract:
1. A magnetic resonance imaging method to separate a signal component produced by cerebrospinal fluid, in a magnetic resonance signal, from other signal components in said magnetic resonance signal, comprising the steps of: placing an examination subject, containing cerebrospinal fluid, in a magnetic resonance data acquisition unit and operating said magnetic resonance data acquisition unit to execute a first signal acquisition sequence to obtain a magnetic resonance signal from the examination subject in which all signal components, including a signal component produced by said cerebrospinal fluid, have the same phase position; operating said magnetic resonance data acquisition unit with said examination subject therein to execute a second signal acquisition sequence with spin echo-based signals to require a magnetic resonance signal wherein the signal component produced by said cerebrospinal fluid has a phase position that is opposite to other signal components in said magnetic resonance signal obtained with said second signal acquisition sequence; and supplying said magnetic resonance signals obtained with said first signal acquisition sequence and said magnetic resonance signals obtained with said second signal acquisition sequence to an image processor and, in said image processor, automatically processing said magnetic resonance signals obtained with said first signal acquisition sequence together with said magnetic resonance signals obtained with said second signal acquisition sequence to produce a magnetic resonance image of the subject in which the signal component produced by said cerebrospinal fluid is substantially suppressed.
