    Hand scintigraphy using 99mTc-Sn-polyphosphate can reveal abnormal bone and joint changes. These findings aid in diagnosing various conditions, including arthritides and vascular diseases, offering insights into digital circulation.

    Area of Science:

    • Nuclear Medicine
    • Radiology
    • Orthopedics

    Background:

    • Bone scintigraphy is a common diagnostic tool.
    • Hand scintigraphy provides detailed imaging of osseous and articular structures.
    • 99mTc-Sn-polyphosphate is a widely used radiotracer for bone imaging.

    Purpose of the Study:

    • To evaluate the diagnostic utility of supplemental hand scintigraphy.
    • To correlate scintigraphic findings with clinical diagnoses.
    • To explore the application of hand scintigraphy in assessing digital circulation.

    Main Methods:

    • Retrospective analysis of 463 patients undergoing routine bone imaging.
    • Utilized supplemental hand scintigraphy with 99mTc-Sn-polyphosphate.
    • Categorized scintigrams into normal and abnormal patterns.

    Main Results:

    • Abnormal scintigraphic features were observed in 29% of patients.
    • Normal activity distribution was noted in 71% of cases.
    • Abnormalities correlated with active arthritides and suggested metabolic bone diseases.
    • Scintigraphy showed potential for assessing digital circulation in vascular diseases.

    Conclusions:

    • Supplemental hand scintigraphy is valuable for diagnosing joint and bone pathologies.
    • Findings can suggest specific diagnoses and pathophysiologic states.
    • This imaging modality may aid in evaluating digital circulation, particularly in obliterative vascular diseases.
