- Orbital Lymphoproliferative Disorders (OLPDs): Value of MR Imaging for Differentiating Orbital Lymphoma from Benign OPLDs
After retrospectively analyzing MR images of 47 patients with proven orbital lymphoproliferative disease, the authors propose that ill-defined lesion margins suggest lymphoma whereas the presence of accompanying sinusitis and intralesional flow voids suggest benign lymphoproliferative disease. Lower ADC and contrast enhancement also suggest lymphoma.
- Use of Non-Echo-Planar Diffusion-Weighted MR Imaging for the Detection of Cholesteatomas in High-Risk Tympanic Retraction Pockets
HASTE DWI was used to examine 16 patients before cholesteatoma surgery and the findings were compared with those seen intraoperatively. HASTE DWI showed 90% sensitivity, 100% specificity, 100% positive predictive value, and 85.7% negative predictive value in this group of patients. Only 1 false-negative finding in an infected cholesteatoma occurred.
