We evaluated 56 consecutive patients with newly diagnosed lymphoma
including 48 with non-Hodgkin's lymphoma (NHL) and 8 with Hodgkin's disease
to determine the clinical and prognostic significance of magnetic resonance
imaging (MRI) of the femoral marrow. MR images of the femoral marrow were
obtained by the T1-weighted spin echo method and the short TI inversion
recovery technique. Abnormal "positive" images were seen in 29 of the 56
patients (52%). All 17 patients with positive biopsy results showed
abnormal images on their femoral marrow MRI. Three "positive" MRI
patterns-scattered (72%), uniform (21%), and nodular (7%)-were observed.
The overall survival of the patients with a positive MRI pattern was
significantly poorer than that of patients with a normal pattern (P =
.0129). Survival did not differ significantly according to MRI pattern. The
3-year survival rate in the patients with a normal MRI pattern was 89.9%
and in the patients with a positive MRI pattern, it was 41.0%. This
difference was statistically significant (P = .0279) when we evaluated only
the patients with NHL. Patients with positive MRI patterns, but a normal
bone marrow histology, showed a significantly shorter survival than those
with a normal MRI pattern (P = .016). These results indicate that abnormal
MR images of the femoral marrow are associated with a significantly poorer
survival in patients with malignant lymphoma, regardless of histologic
findings in the marrow.
