MRI sequences for the detection of individual lymph nodes in regional breast radiotherapy planning.OBJECTIVE
 By identifying individual LNs, MRI-based delineations may reduce target volumes and thereby toxicity.  We optimized MRI sequences for this purpose.  Supine MRI was explored at 1.5 T in RT position (arms in abduction).  5 MRI techniques were optimized in 10 and evaluated in 12 healthy female volunteers.  T1w MRI showed an intermediate number of LNs (17), provided valuable anatomical information, but lacked LN contrast.


 Explicit LN imaging was achieved, in supine RT position, using MRI.  T1w MRI showed anatomical information.  MRI enables direct delineation of individual LNs.


 Our optimized MRI scans enable accurate target definition in MRI-guided regional breast RT and development of personalized treatments.
