static bone imaging

When local bones are damaged, such as inflammation, tumors, fractures, etc., causing local blood flow and/or changes in bone mineral salt metabolism, all of them will show abnormal increase in radioactivity at the corresponding sites. These abnormalities usually manifest themselves in the early stage of the disease. Static bone imaging can make early diagnosis and clear positioning of various bone diseases. Basic Information Specialist Category: Oncology Inspection Category: Radionuclide Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: The range of visualization is a certain part of the bone, and the image is clear and the quality is good. Positive: 1. There is a history of malignant tumor suspected of bone metastasis; 2. Determine the presence or absence of metastasis of the primary bone tumor, determine the treatment plan; 3. Determine the fractures that are difficult to find on the X-ray and diagnose the stress fracture early; 4. Metabolic bone disease And the auxiliary diagnosis of osteoarthrosis; 5, the cause of unknown bone pain, exclude bone tumors. Tips: In the recent use of tinctures, patients need to discharge the tincture and then check. Normal value The range of visualization is a certain part of the bone, and the image is clear and the quality is good. Clinical significance Abnormal result 1. There is a history of malignant tumor suspected of bone metastasis; 2. Determine the presence or absence of metastasis of the primary bone tumor, determine the treatment plan; 3. Determine the fractures that are difficult to find on the X-ray and diagnose the stress fracture early; 4. Metabolic bone disease And the auxiliary diagnosis of osteoarthrosis; 5, the cause of unknown bone pain, exclude bone tumors. People who need to be examined: Patients with bone disease or suspected bone tumors can be examined. Positive results may be diseases: bone fracture, metastatic bone tumor considerations Pre-intestation contraindications: 500ml of water after 30 minutes of intravenous infusion of the tracer, check within 2 to 5 hours, before the examination to resolve the urination (some patients with difficulty in urinary catheterization), remove the metal objects. Requirements for inspection: When the patient resolves urination, try to avoid urine contamination of the clothes, so as not to affect the inspection. If it is found to be contaminated, it should be removed first. If you are unable to stay in bed because of pain, first give an analgesic drug. Inspection process Systemic or localized static bone imaging after 2-3 hours of intravenous injection of bone imaging agent, most of the imaging agents that have not entered the bone tissue have been excreted from the kidneys, and the radioactivity in the blood has been significantly reduced as the background is clear, and the bone imaging is clear. A large amount of drinking water after injection can accelerate the excretion of Tc-MDP through the kidney. Before the imaging, the subject urinates to reduce the radioactivity of the urine in the bladder to interfere with the image. Since the bone imaging agent is unevenly distributed in the body bone of normal people, the method of comparing the radioactivity of the left and right sides of the symmetrical portion is used to identify the lesion site and the normal bone tissue. Not suitable for the crowd Inappropriate people: In the recent use of tinctures, patients should be discharged after the expectorant is discharged. Adverse reactions and risks Nothing.
