Development of native and contrast enhanced magnetic resonance imaging for the characterization of cardiovascular disease
… for vessel wall imaging. It however requires a Look Locker scan to choose the correct inversion time (TI) to achieve post-contrast blood suppression. The quadruple inversion recovery (QIR) sequence was later developed to suppress blood before and after contrast using identical imaging …

Vergleich zweier Kontrastmittel in der kernspintomographischen Vitalitätsdiagnostik des Myokards
… enhancement images with IR turbo-Flash-sequence. Look locker sequences were also measured. MR imaging was gathered of 30 patients receiving 0,2 mmol/kg KG Gd-DTPA and 30 patients receiving 0,1 mmol/kg KG Gd-BOPTA. Each group consisted of 26 patients with myocardial infarction. T1 values were …

Untersuchung des intrazellulären Kontrastmittels MnCl2 zur Darstellung des akuten Myokardinfarktes
… media MnCl2 per kilogram of body weight. Look-Locker images were acquired to measure longitudinal relaxation times (T1) in normal myocardium, reperfused infarction, chamber blood and autochthonous back musculature. T1 values were measured before the administration of MnCl2 and at 15-minute …

Improved Techniques For Acquisition and Analysis of Dynamic Contrast-Enhanced Magnetic Resonance Imaging For Detecting Vascular Permeability In The Central Nervous System
… results. To obtain fast and accurate T1 map, the Look-Locker acquisition technique was implemented with a novel and truly centric k-space segmentation scheme. In addition, an original multi-step curve fitting procedure was developed to increase the accuracy of T1 estimation. A view sharing …

An Information Theory Model For Optimizing Quantitative Magnetic Resonance Imaging Acquisitions
… to a 3D-quantification using an interleaved Look-Locker acquisition sequence with T2 preparation pulse (3D-QALAS) signal model for synthetic MRI. In this framework, mutual information is used to measure the information gained by a measurement as a function of acquisition parameters, …

Three-dimensional T1 quantification techniques for assessment of cartilage quality using dGEMRIC
… within the volume. As part of the work a 3D Look-Locker (3D-LL) T1 quantification pulse sequence have been created. In addition, new methods were developed for correction of B1 inhomogeneities and slab profile flip angle variations in the 3D-LL data. From in vivo and phantom measurements the …
