title: [Magnetic resonance imaging of the ankle joint and foot: possible diagnostic errors].
abstract: The paper deals with the visualizing study of the ankle joint and foot by MRI and with the problems in the interpretation of magnetic resonance images in health. For this, 50 healthy volunteers without diseases and lesions of the ankle joint and foot were examined. The study was performed by using flexible superficial coils and T1-, T2-, and proton-weighed pulse-sequences in the orthogonal projections. The articular surfaces and cavity of the ankle joint were evaluated. The specific features of visualization of the muscles and tendons of this area and the pattern of fluid under their membranes were explored. The typical location of the "magic corner" phenomenon was revealed. The individual specific features of identification of the ligaments of the ankle joint and foot and plantar aponeurosis were defined. The features of visualization of bones simulating abnormalities were studied. A category of normalcy in the MRI of the ankle joint and foot was formulated.
