Materials
Between April 2007 and May 2009, 96 breast conservation therapy were performed for invasive ductal carcinoma (IDC) at our hospital. Fourteen patients with stage IIA-IIIB palpable IDC were enrolled in a study investigating the effects of NAC on tumor imaging. All patients underwent MMG, US, MRI, and RVS before and after NAC. Nine patients received lumpectomy, and 5 received mastectomy.
Methods
MRI
MRI was obtained on a Magnetom 1.5-T imager (Siemens, Germany) using a flexible body surface coil. All patients were examined in the supine position as near as possible to the sonography.
Real-time Virtual Sonography (RVS)
RVS consisted of a magnetic generator, magnetic sensor, and workstation (Fig. 1, 2). The magnetic sensor installed on the tip of the probe sensed the magnetic field and detected the position and motion of the probe while it was scanning (Fig. 2).
