Claim Text:
1. A method of displaying hyperintense magnetic resonance (MR) signal sources in a reconstructed MR image of a subject, comprising: using a control computer in order to operate an MR data acquisition scanner with a pulse sequence and acquire MR data, with the MR data including hyperintense MR signals acquired during an echo time of the pulse sequence that is less than one millisecond, from nuclear spins within the subject that act as a source of the hyperintense MR signals; a subject is situated inside the MR data acquisition scanner, wherein said source of the hyperintense MR signals; is also within an extent of influence being generated by a magnetically active dipole that imparts both a magnetic susceptibility disturbance and a dephasing onto said nuclear spins that act as the source of said hyperintense MR signals; in said control computer, formulating said pulse sequence in order to cause said echo time of the pulse sequence to be less than a millisecond, and in order to also suppress an acquisition of undesired signals occurring in said acquired MR data, in at least a predetermined MR signal frequency range, and whereby the less than a millisecond echo time of the pulse sequence prevents both the dipole imparted magnetic susceptibility disturbance and said dephasing from having the time required to degrade said hyperintense MR signals down to an extent that precludes an unambiguous visualization of said hyperintense MR signal source in an MR image that is reconstructed from said acquired MR data; and in a processor, reconstructing said MR image from said acquired MR data, with said hyperintense MR signal source being unambiguously visualized in said reconstructed MR image, as a direct result of the echo time being less than 1 millisecond in the formulated pulse sequence and making said reconstructed MR image available from said processor in electronic form as a data file.
