Figure 1From: Does gap-free intensity modulated chemoradiation therapy provide a greater clinical benefit than 3D conformal chemoradiation in patients with anal cancer?Comparison of dose distribution on planning CT with 3D-CRT and IMRT for a same patient with a locally advanced T3N+ anal cancer. Legend: The isodose distribution shows up in colorwash with the 95% isodose line selected Left column (A.) axial CT slice using 3D-CRT technique with small coronal and sagittal views above; Right column (B.) axial CT slice using IMRT technique. with small coronal and sagittal views above.Back to article page
