Magnetic resonance imaging appearance and changes on intracavitary Gliadel wafer placement: A pilot study

Figure 4 Graphic illustration. Post-treatment changes and time course. This diagram illustrates a progressive increase in pericavitary enhancement and FLAIR hyperintensity that occurs within the first 2 mo of Gliadel wafer deposition. At the 2 mo mark, all patients (5/8) without recurrence demonstrated a steady decline in post-treatment changes on their magnetic resonance imaging (MRI) relative to the immediate prior examination (dark gray-black line). All (3/8) patients who had recurrence demonstrated a continued increase in enhancement and FLAIR hyperintensity relative to their immediate prior MRI study (light gray line).
