  • Title: MR imaging of uterine leiomyomas and their complications.
    Author: Hamlin DJ, Pettersson H, Fitzsimmons J, Morgan LS.
    Journal: J Comput Assist Tomogr; 1985; 9(5):902-7. PubMed ID: 4031167.
    Abstract:
    Magnetic resonance (MR) imaging in eight patients with uterine leiomyomas and in eight normal female volunteers clearly depicted the size, shape, and position of the corpus uteri and demonstrated adjacent anatomic structures to good advantage in transaxial, coronal, and sagittal planes. Spin echo (SE) with short repetition time (TR) and short echo time (TE) values was judged best for overall delineation of anatomic structures. Longer TR and TE times were used to differentiate myometrium from endometrium. Detection and characterization of complications of uterine myomas were facilitated by the use of multislice/multiecho SE techniques, but in general TE values greater than 60 ms were not needed to differentiate endometrium from myometrium and in most cases did not improve the MR depiction of abnormalities. Calculated T1 and T2 relaxation times from this preliminary study do not demonstrate a clear advantage in further characterizing uterine abnormalities.
