Assessment of breast cancer recurrence with contrast-enhanced subtraction MR imaging: preliminary results in 26 patients.

摘要: Local relapse was suspected in 26 women treated conservatively for breast cancer. All underwent routine magnetic resonance (MR) imaging and a dynamic MR subtraction study after injection of gadolinium-tetraazacyclododecanetetra-acetic acid. Twelve had no local relapse. Surgical biopsy enabled confirmation recurrence 14 patients. Routine did not allow differentiation from glandular or scar tissue. Except one case fat necrosis, patients without showed contrast enhancement 1 minute 34 seconds injection. At imaging, all recurrences Nodular (n = 11) found invasive carcinoma, whereas linear seen intraductal carcinoma 3). Subtraction precontrast postcontrast images always allowed better visualization enhancement. Contrast-enhanced may prove to be accurate diagnosis lo...
