Currently there is no image-guided modality which is sufficient and exact enough to evaluate the perfusion of tissue in its different layers after transplantation of microvascular flaps. Examination of capillary filling after compression (refill) allows merely a vague estimation. The cutaneous blood flow can be shown with different methods of fluoroscopy, but the perfusion of deeper tissue laye...
This study investigates the effectiveness of hundreds of texture features extracted from voxel-based dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) parametric maps for early prediction of breast cancer response to neoadjuvant chemotherapy (NAC). In total, 38 patients with breast cancer underwent DCE-MRI before (baseline) and after the first of the 6-8 NAC cycles. Quantitative ph...
Meningioma is not uncommon case; however, the differentiation of high-grade from low-grade meningioma important. The rate recurrence grade I 7-20%, but in II 30-40% and III 50-80%. Non-invasive MRI techniques that can differentiate meningiomas before surgery are useful for surgical planning subsequent treatment. We present a review article some case studies (WHO I) III) with conventional contin...
