Fig. 2

Radiologist-defined tumor contours on MRI corresponding to the four example lesions depicted in Fig. 1. Inserts show contours transferred to co-registered Y-90 PET/CT-based dose maps. Mean dose values are indicated before PVC. a Large, well defined (code 46.1). b Small, well defined (39.3). c Large, poorly defined (49.1). d Small, poorly defined (55.4). Contours drawn by the same radiologist are indicated in the same color (Pink = radiologist A, Yellow = radiologist B, Blue = radiologist C)
