  • Title: Limitations of the keyhole technique for quantitative dynamic contrast-enhanced breast MRI.
    Author: Bishop JE, Santyr GE, Kelcz F, Plewes DB.
    Journal: J Magn Reson Imaging; 1997; 7(4):716-23. PubMed ID: 9243393.
    Abstract:
    The effect of keyhole data acquisition on quantitative analysis of dynamic MRI was examined. Experiments were performed retrospectively on raw data obtained from clinical dynamic contrast-enhanced breast imaging procedures. The effects of keyhole phase-encoding acquisition and type of reconstruction algorithm on the accuracy of derived quantitative parameters was assessed. Results indicate that the minimum keyhole size used should be restricted by the approximate minimum size of the expected lesions. Furthermore, reconstruction algorithms that offer improved image resolution do not circumvent this restriction.
