Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an MR lumbar vertebra image auxiliary device and an MR imaging device.
Background
Magnetic resonance imaging is a modern medical diagnosis technology which is based on the basic principle that atomic nuclei with non-zero magnetic moments can resonate in an external magnetic field and generate corresponding radio-frequency signals according to the pathological condition of human tissues, and the signals are acquired and the images are reconstructed by using a computer, so that medical images reflecting the pathological condition of the human tissues are obtained.
At present, most middle-aged people in China suffer from lumbar diseases of different degrees, mainly including primary lumbar intervertebral disc protrusion, lumbar intervertebral disc protrusion and the like, secondary lumbar spinal stenosis and the like, and the most main diagnosis method for the diseases is to efficiently and accurately analyze pathological conditions by scanning and imaging lumbar parts through magnetic resonance imaging equipment.
When a patient with lumbar vertebra disease is in a standing state, the lumbar vertebra part bears more compression than that in a lying state due to the existence of the gravity of the human body, so that the clinical manifestations of lumbago, lower limb radiating pain and the like are more obvious compared with the lying state. Currently, when the MR apparatus is used for spine scanning, a patient is usually laid on an examination bed, a scanning coil is covered on the abdomen, and then a scanning operation is performed. The compression of the self weight of the human body to the lumbar vertebra of the patient in a standing state in normal work and life is ignored in the scanning mode, and the clinical performance of the lumbar vertebra patient in a bed-lying state is different and not obvious enough compared with that in the standing state, so that the pathological condition of the lumbar vertebra of the human body in the standing state cannot be truly reflected by the scanned lumbar vertebra image, and the diagnosis accuracy of a doctor is influenced. In addition, the clinical manifestations of the patients in the early stage of the lumbar diseases are not obvious, and when the existing scanning mode is adopted for diagnosis, important pathological information of the scanned images is missed, so that doctors can make inaccurate diagnosis, and the optimal diagnosis and treatment time of the early stage of the diseases is delayed.
