<p>The practical use of existing techniques for measuring characteristic magnetic resonance (MR) parameters such as spin-lattice relaxation time ( T1 ), spin-spin relaxation time ( T2 ), proton density ( p ), T2*, etc., is limited by the extended periods of time required for the measurement. It is thus desirable to have a method of measuring or quantifying characteristic MR parameters in a shorter period of time. Accordingly, a method of quantifying at least one characteristic MR parameter in a subject is hereby disclosed. The method comprises identifying (103) a region to be scanned in the subject, defining (105) a sub-region within the identified region, acquiring (107) MR data from the defined sub-region, and processing (109) the acquired MR data to quantify the at least one characteristic parameter in the defined sub-region.</p> |
