    摘要： The disclosure of the present invention provides for an imaging apparatus and methods for imaging the cranio-cervical junction of a patient using magnetic resonance. The apparatus is adapted to slide over the patient's head, and includes a saddle element and a solenoid element. The saddle element has a length that extends along a superior-inferior axis of the patient, and a circumference along an axial plane of the patient when the apparatus is slid over the patient's head, so as to define a substantially cylindrical volume. The solenoid element attaches to the saddle element at about a midpoint of the saddle element's length, so as to be positioned along an axial plane of the patient when the apparatus is slid over the patient's head. This configuration allows for the cranio-cervical junction of the patient to be positioned in the cylindrical volume when the apparatus is slid over the patient's head.

    摘要： An apparatus for magnetic resonance imaging includes a magnet, a patient support, and a contoured quadrature coil. The contoured quadrature coil includes a ring coil and an angled butterfly coil. The angled butterfly coil may have a front outer section, an inner section, and a back outer section. The front outer section and the back outer section may be oriented diagonally from the plane of the ring coil such that a portion of the front outer section and/or the back outer section are disposed above the plane of the ring coil and a portion of the front outer section and/or the back outer section are disposed below the plane of the ring coil. Thus, the planes of the front and back outer sections may be angled with respect to each other, and the inner section may be substantially pyramidal and disposed along or below the plane of the ring coil.
