View larger version (94K): [in this window] [in a new window] [as a PowerPoint slide]   Fig. 1A —67-year-old woman with invasive ductal carcinoma. Oblique coronal reconstruction image shows lobular mass (arrow) with spiculated margin and homogeneous internal enhancement in left breast.

View larger version (79K): [in this window] [in a new window] [as a PowerPoint slide]   Fig. 1B —67-year-old woman with invasive ductal carcinoma. On maximum-intensity-projection (MIP) image, three vessels (arrows) are counted in both breasts. As result, whole-breast vascularity in cancer-bearing breast is not increased compared with contralateral breast. Patient underwent total mastectomy and was diagnosed as having stage I (T1N0M0) cancer. Histopathology confirmed invasive ductal carcinoma with nuclear grade of 3 and histologic grade of 1.

On maximum-intensity-projection (MIP) image, two vessels (long arrows) in right breast and one vessel (short arrow) in left breast are counted. As result, cancer-bearing breast shows mild increased vascularity compared with contralateral breast. Patient underwent total mastectomy and was diagnosed as having stage I (T1N0M0) cancer. Histopathology confirmed invasive ductal carcinoma with nuclear grade of 3 and histologic grade of 1.

On maximum-intensity-projection (MIP) image, two vessels (short arrows) in right breast and four vessels (long arrows) in left breast are counted. As result, cancer-bearing breast shows moderate increased vascularity compared with contralateral breast. Patient underwent total mastectomy and was diagnosed as having stage IIB (T3N0M0) cancer. Histopathology confirmed invasive ductal carcinoma with nuclear grade of 1 and histologic grade of 3. Tumor is accompanied by extensive intraductal component.

Oblique coronal reconstruction images show irregularly shaped mass (short arrow) with spiculated margin and peripheral rim enhancement in left breast. There are multifocal satellite nodules (long arrows, B) around main tumor.

On maximum-intensity-projection (MIP) image, one vessel (short arrow) in right breast and four vessels (long arrows) in left breast are counted. As result, cancer-bearing breast shows prominent increased vascularity compared with contralateral breast. There are multiple metastatic lymph nodes (arrowheads) at left axilla. Patient underwent total mastectomy and was diagnosed as having stage IIIC (T2N3M0) cancer. Histopathology confirmed invasive ductal carcinoma nuclear grade of 1 and histologic grade of 3. Tumor is accompanied by extensive intraductal component.

Graphs show T stage (A), N stage (B), cancer stage (C), nuclear grade (D), and histologic grade (E). Ipsilateral increased vascularity correlated to the T stage of tumor (p = 0.009), N stage (p = 0.003), cancer stage (p = 0.001), nuclear grade (p = 0.046), and histologic grade (p = 0.008).
