PURPOSE To apply the low-rank plus sparse (L+S) matrix decomposition model to reconstruct undersampled dynamic MRI as a superposition of background and dynamic components in various problems of clinical interest. THEORY AND METHODS The L+S model is natural to represent dynamic MRI data. Incoherence between k-t space (acquisition) and the singular vectors of L and the sparse domain of S is req...

Tumor-related vessel length (TVE) was quantified as the number of pixels skeletonized tumor vessels on ultrafast dynamic contrast-enhanced MRI (UF-DCE MRI). The association between TVE and breast cancer subtypes investigated. Invasive presenting with human epidermal growth factor receptor 2 (HER2) associated increased tumor-related length.

Histogram analysis of intravoxel incoherent motion and dynamic contrast-enhanced MRI with the two-compartment exchange model in glioma

PURPOSE To evaluate the value of breast MRI in analysis of papillomas of the breast. MATERIALS AND METHODS From 1996 to 2004, 94 patients underwent surgery due to papillomas of the breast. Among them, 21 patients underwent 3D fast low angle shot (FLASH) dynamic breast MRI. Eight masses were palpable and 11 of 21 patients had nipple discharge. Two radiologists indifferently analyzed the locati...
