Five patients with acquired coronal clefts in lower lumbar vertebral bodies are presented. The appearances on plain radiographs, skeletal scintigraphy, discography, computed tomography and magnetic resonance imaging (MRI) are described. The aetiological factors are discussed with particular emphasis on the role of the intervertebral disc and the discovertebral junction in the pathomechanics of vertebral body injury. Magnetic resonance imaging was helpful in the radiological assessment and provided information from which an explanation of the clefts could be proposed.
Nuclear magnetic resonance images of the knee were obtained from three normal volunteers and from two patients. The pathology included an osteosarcoma of the distal femur and a fracture of the tibia. Steady State Free Precession (SSFP) techniques were used with a 0.15 Tesla resistive type magnet. Normal anatomy was well displayed and the size of the osteosarcoma was accurately predicted. Using SSFP techniques, the blood in the knee joint was not visualised, but the underlying tibial fracture was clearly outlined.
