What is the role of systemic bone disease screening?

summary

Systemic bone disease screening is a technology that injects osteophilic radiopharmaceuticals into the body by vein, and then carries out systemic bone imaging by SPECT instrument. It can clearly show the shape of the whole body bone, and can reflect the blood supply and metabolism of the bone. It has high sensitivity in the exploration of bone diseases, and can show the existence of lesions before X-ray examination. It has important value in the diagnosis and curative effect evaluation of various bone diseases. Let's share my experience with you.

What is the role of systemic bone disease screening?

(1) concentrated foci (hot area) (single, multiple) are common in the bone, such as trauma, fracture, surgical injury. Inflammation may be osteomyelitis, abscess, osteoarthritis. Tumors may include bone metastases, lung cancer, prostate cancer, breast cancer, renal cancer, and thyroid cancer. Benign bone tumors include osteochondroma, endophytic osteoma and bone cyst. Malignant bone tumors may be osteosarcoma, Ewing's osteoma and chondrosarcoma.

(2) Radiation defect (cold zone) is common in the sternum, thoracic vertebrae and pelvic bone may be malignant bone metastases (80-90%),. It is also necessary to consider the possibility of benign lesions such as necrosis, cyst, frostbite, radiotherapy, surgical trauma and resection.

(3) the bone can be seen in the shape of fried surface ring, which can be trauma, such as nonunion fracture, necrosis, radiation treatment. It may also be inflammation and Paget's disease. (4) bone superscan is a disease of multiple bone metastases (prostate cancer, breast cancer, etc.) and primary hyperparathyroidism.

matters needing attention

Unsuitable crowd: no pre examination taboo: no special taboo, examination requirements: intravenous injection of reflective drugs and imaging may be time-consuming, need to wait patiently.
