Summary
Magnetic resonance (MR) imaging of multiple myeloma bone marrow revealed abnormal patterns in 82% of patients. These abnormal MR imaging patterns, excluding nodular patterns, correlated with poorer patient survival, indicating prognostic value.
Area of Science:
- Radiology
- Oncology
- Hematology
Background:
- Multiple myeloma is a cancer of plasma cells.
- Accurate prognostic factors are crucial for managing multiple myeloma patients.
- Bone marrow involvement is a hallmark of multiple myeloma.
Purpose of the Study:
- To investigate the utility of magnetic resonance (MR) imaging in characterizing bone marrow patterns in multiple myeloma.
- To correlate MR imaging findings with laboratory data and patient survival.
Main Methods:
- Sixty-one multiple myeloma patients underwent spinal MR imaging using sagittal T1-weighted and short inversion time (TI) inversion recovery (STIR) sequences.
- Bone marrow MR patterns were classified as diffuse, nodular, combined diffuse and nodular, or normal.
- Correlations between MR patterns, laboratory findings, and survival were analyzed.
Main Results:
- Abnormal MR imaging patterns were observed in 82% of patients.
- Significant correlations were found between MR patterns and laboratory markers including WBC, hematocrit, platelet count, serum albumin, and marrow plasmacytosis.
- Patients with abnormal MR patterns (excluding nodular) had significantly poorer survival compared to those with normal patterns.
Conclusions:
- Spinal MR imaging is effective in visualizing bone marrow involvement in multiple myeloma.
- MR imaging patterns of bone marrow can serve as a valuable prognostic indicator in multiple myeloma.
- The presence of diffuse or combined diffuse and nodular MR patterns is associated with a worse prognosis.
