Outpatient visits often see patients taking imaging tests from the field, often feeling that it is the lack of some tests, so in the end what tests need to be done well? I think it depends on the location and disease you are looking for. Spine Cervical and thoracic spine: front and side X-rays, MRI, CT scan of the diseased segment if necessary, suspected instability Second Hospital of Harbin Medical University, Minimally Invasive Surgery of Joint Diseases, Department of Sports Medicine Lv Songzen can be forward flexion and backward extension position film, cervical spine can also be left and right oblique position film. Lumbar spine: front and side X-rays, CT and MRI are available. Hip Orthopantomographs of the pelvis, lateral films of the upper femur, MRI for early detection of femoral head necrosis, and CT or 3DCT for fractures Knee Orthopantomographs, MRI for meniscus, cartilage, and ligament damage. Fracture plus CT Shoulder orthogonal film, axillary shaft lateral film, supraspinatus exit film, MRI, fracture plus CT or 3DCT Ankle orthogonal film, MRI to see the degree of cartilage damage Elbow orthogonal film MRI to see the degree of cartilage damage Extremities generally orthogonal film, if other fractures to do CT, suspected soft tissue injury, swelling to do MRI, suspected bone metastases to do whole body bone ECT, bone marrow aspiration Bone marrow aspiration. Therefore, it is necessary to look at the hip and knee joints if they are painful and there is no problem with the general ortho-lateral film.
