Summary

Bone marrow imaging with scintigraphy and magnetic resonance (MR) imaging aids lymphoma staging. These techniques, alongside biopsy, improve detection of bone marrow infiltration, especially when biopsy results are inconclusive.

Area of Science:

  • Oncology
  • Radiology
  • Hematology

Background:

  • Accurate staging of malignant lymphoma requires comprehensive evaluation of bone marrow involvement.
  • Traditional bone marrow biopsy may have limitations in detecting infiltration, potentially leading to false-negative results.

Purpose of the Study:

  • To compare the efficacy of scintigraphy, magnetic resonance (MR) imaging, and bone marrow biopsy in detecting bone marrow infiltration in lymphoma patients.
  • To assess the role of imaging modalities as adjuncts to biopsy in lymphoma staging.

Main Methods:

  • Evaluated bone marrow in 107 patients with Hodgkin and non-Hodgkin lymphoma using scintigraphy, MR imaging, and biopsy.
  • Classified results from imaging and biopsy into normal (class 0), reactive changes (class 1), or suspicious for infiltration (class 2).

  • Correlated imaging findings with biopsy results and autopsy findings in select cases.

    • Main Results:

    • Complete agreement between imaging and biopsy was observed in approximately 50% of patients.
    • False-negative findings were frequent with both imaging techniques in chronic lymphocytic leukemia.
    • Repeat or guided biopsies confirmed imaging findings when initial biopsies were negative or suggestive of reactive changes.

    Conclusions:

    • Scintigraphy and MR imaging are valuable adjuncts to blind biopsy for complete bone marrow evaluation in malignant lymphoma staging.
    • Negative biopsy findings do not exclude tumor involvement, highlighting the importance of complementary imaging techniques.
    • Routine inclusion of scintigraphy and MR imaging in lymphoma staging protocols is recommended.
