Nodular protrusions of iTBC. Oblique axial (A) and oblique coronal (B) HRT2WI images of a patient with rectal cancer (PT3N1) showed multiple irregular nodular protrusions (white arrows) appeared at the margin of the primary tumor. Some nodules had lobulated edges (green arrows), and some nodules had irregular cords (black arrows). Oblique axial HRT2WI (C) image of another patient with rectal cancer (PT3N1) showed the primary rectal tumor had a large nodule protruding (white arrow) at the right margin, and this nodule protrusion had small nodules (green arrow) and multiple irregular cords (multiple black arrows) at its edge
