PURPOSE Novel demonstration of R2∗ and tissue density estimation in infant lungs using 3D ultrashort echo time MRI. Differences between adult and neonates with no clinical indication of lung pathology is explored, as well as relationships between p

PURPOSE: The MR properties (chemical shifts and R(2)* decay rates) of dissolved-phase hyperpolarized (HP) (129)Xe are confounded by the large magnetic field inhomogeneity present in the lung. This work improves measurements of these properties using

Purpose Image quality in computed tomography (CT) is usually not quantified in real time from patient scans. Rather, phantom scans are employed to measure the contrast, noise, and spatial resolution properties of a given system. This approach, howeve

Purpose Quantification of the frequency, understanding the motivation, and documentation of the changes made by CT technologists at scan time are important components of monitoring a quality CT workflow. Methods CT scan acquisition data were collecte

Purpose: Proper patient positioning is essential in CT to ensure automatic exposure control functions properly, noise uniformity, and CT number uniformity. This work describes how table height can be used as a surrogate for proper patient positioning

Purpose: With increasing emphasis on CT image quality and low dose, quality activities analyzing noise levels in images will need to be increasingly automated. This work describes a new automated method for characterizing noise in CT. To obviate the
