Multiparametric Renal Magnetic Resonance Imaging: Validation, Interventions, and Alterations in Chronic Kidney Disease.
Eleanor F. Cox,Charlotte Buchanan,Christopher R. Bradley,Benjamin Prestwich,Huda Mahmoud,Maarten W. Taal,Nicholas M. Selby,Susan T. Francis +7 more
TL;DR: Multiparametric MRI is a powerful technique for the assessment of changes in structure, hemodynamics, and oxygenation in a single scan session and provides the potential to assess the pathophysiological mechanisms in various etiologies of renal disease, and to assessThe efficacy of drug treatments.

Lu-Ping Li,Huan Tan,Jon Thacker,Wei Li,Ying Zhou,Orly F. Kohn,Stuart M. Sprague,Stuart M. Sprague,Pottumarthi V. Prasad +8 more
TL;DR: The results support the use of arterial spin labeling in the evaluation of renal blood flow in patients with a moderate level of CKD, and whether these measurements can identify patients at risk for progressive CKD requires further longitudinal follow-up.

Least squares quantization in PCM
TL;DR: In this article, the authors derived necessary conditions for any finite number of quanta and associated quantization intervals of an optimum finite quantization scheme to achieve minimum average quantization noise power.
Least Squares Quantization in PCM
TL;DR: The corresponding result for any finite number of quanta is derived; that is, necessary conditions are found that the quanta and associated quantization intervals of an optimum finite quantization scheme must satisfy.

Heterogeneity of Angiogenesis and Blood Vessel Maturation in Human Tumors: Implications for Antiangiogenic Tumor Therapies
Anne Eberhard,Sebastian Kahlert,Valentin Goede,Bernhard Hemmerlein,Karl H. Plate,Hellmut G. Augustin +5 more
TL;DR: Angiogenesis was found to be present in all tumors with characteristic and significant differences between the tumor types and there was a considerable degree of heterogeneity in the intensity of angiogenesis within each tumor group, as indicated by large standard deviations.
