Figure 1From: Computer-aided detection (CAD) system for breast MRI in assessment of local tumor extent, nodal status, and multifocality of invasive breast cancers: preliminary study How to measure the tumor extent. The longest diameter of a breast tumor was recorded using each modality; MMG (A), US (B), CT (C), MRI without CAD (D), MRI with CAD (E), and FDG-PET (F). For measurement of tumor extent with CAD, an enhancing tumor above the threshold was selected with the color overlay map, and then CAD-generated maximum tumor size was recorded.Back to article page
