Systemic skeletal disease screening

Systemic bone disease screening is a technique in which a bone-proliferating radiopharmaceutical is injected into the body by intravenous injection and then subjected to whole body bone imaging by a SPECT instrument. It can clearly show the shape of the whole body bone, and it can reflect the blood supply and metabolism of the bone. It has high sensitivity in the exploration of bone disease, and can show the existence of the lesion before the abnormality of X-ray examination. The diagnosis and efficacy evaluation of bone diseases is of great value. A whole body bone imaging can detect more than 50 bone diseases. Basic Information Specialist classification: growth and development check classification: X-ray Applicable gender: whether men and women apply fasting: not fasting Tips: Intravenous reflex drugs and imaging can be time consuming and require patience. Normal value There is no concentrated foci (hot zone) on the bones, no radioactive defects (cold zone), no bones in the bones, no super-images and flicker in the bones, and no imaging outside the bones. Clinical significance Abnormal results: 1. Skeleton see concentrated foci (hot zone) (single hair, multiple hair) is common in trauma for injury, fracture, and surgical injury. The inflammation may be osteomyelitis, abscess, or osteitis. Tumors may have bone metastases, lung cancer, prostate cancer, breast cancer, kidney cancer, and cancer. Benign bone tumors have osteochondroma, endogenous osteoma, and bone cysts. Malignant bone tumors may be considered osteosarcoma, Uighur osteosarcoma, chondrosarcoma. It may also be a bone metabolic disease such as (Paget's disease) malformation osteitis, hyperparathyroidism, osteoporosis. A hot zone on the periosteum is a new bone formation that can be judged by non-pulmonary osteoarthrosis (HPO). On the joint, it can provide a basis for osteoarthritis, rheumatism and rheumatoid arthritis, and degenerative joint disease. In addition, it can also be granuloma, fibrous bone dysplasia. 2. Skeletal see radioactive defects (cold zone) common in the sternum, thoracic vertebrae and pelvic bone may be malignant bone metastases (80-90%). Also need to consider benign lesions such as necrosis, cysts, frostbite, radiotherapy, surgical trauma, resection. 3. Bone sees the doughnut shape for trauma, such as non-union fracture, necrosis, radiation therapy. It may also be inflammation and Paget's disease. 4. Skeletal see super image (Superscan) is a partial multiple bone metastases (prostate cancer, breast cancer and other metastases), the primary hyperparathyroidism. 5. Skeletal seeing flicker phenomenon (Flare) can be improved for chemotherapy and other treatments. 6. Extra-osseous imaging The urinary system may be a renal concentrating urinary tract obstruction, hydronephrosis, acute tubular necrosis, and interstitial nephritis. Focal renal concentration is a malignant tumor in or around the kidney, kidney metastasis of lung cancer, and nephroblastoma. Sparse defects are abscesses, cysts, benign tumors, and partial metastases. Morphological abnormalities may be unilateral enlargement, shrinkage (function impairment, vascular stenosis). Imaging on soft tissue can diagnose non-tumor lung cancer (oat cell cancer), breast cancer, uterine cancer, colon cancer, lymphoma, neurofibroma and the like. The thyroid ring cartilage calcification and soft tissue metastasis were examined on the neck. Stomach delabeling sputum imaging, surgical ureterostomy, colon cancer. People who need to be examined: people with abnormal bones, sub-healthy people, and high-risk groups of cancer. Precautions Taboo before inspection: no special contraindications. Requirements for examination: Intravenous reflex drugs and imaging may be time consuming and require patience. Inspection process The osteogenic radiopharmaceutical is injected intravenously into the body, and then subjected to whole body bone imaging by a SPECT instrument. Not suitable for the crowd Inappropriate crowd: None. Adverse reactions and risks Nothing.
