The bone scan in inflammatory osseous disease.

H Handmaker, R Leonards

    Seminars in Nuclear Medicine
    |January 1, 1976
    PubMed
    Summary

    The technetium-99m-phosphate bone scan is a sensitive tool for detecting bone inflammation, often showing changes before X-rays. Careful interpretation with clinical data improves diagnostic accuracy for bone infections.

    Area of Science:

    • Nuclear Medicine
    • Radiology
    • Pediatric Infectious Diseases

    Background:

    • Bone inflammation and infection present diagnostic challenges.
    • Early detection of osteomyelitis is crucial for effective treatment.
    • Conventional radiography may not reveal early osseous changes.

    Purpose of the Study:

    • To evaluate the utility of the 99mTc-phosphate bone scan in diagnosing bone inflammatory diseases.
    • To highlight the advantages of bone scintigraphy over radiography in early disease detection.
    • To discuss the role of bone scans in conjunction with other imaging modalities for infectious diseases.

    Main Methods:

    • Utilized 99mTc-phosphate bone scintigraphy for evaluating patients with suspected bone inflammation.
    • Correlated scan findings with clinical presentation, roentgenography, and other diagnostic tests.
    • Assessed the efficacy of bone scans in differentiating various bone diseases, including osteomyelitis.

    Main Results:

    • 99mTc-phosphate bone scans demonstrate high sensitivity and reliability in detecting bone inflammation.
    • Scans can become positive within 24 hours of symptom onset, preceding radiographic evidence by 10-14 days.
    • Combined use with 67Ga-citrate scans is valuable for diagnosing infectious diseases, particularly in pediatric patients.

    Conclusions:

    • The 99mTc-phosphate bone scan is a safe and effective method for evaluating suspected bone inflammatory conditions.
    • While limitations like "cold" defects exist, correlation with clinical and other diagnostic data minimizes interpretation issues.
    • Bone scintigraphy is an indispensable tool in the work-up of bone infections, especially in pediatric populations.
