Improved delayed enhanced myocardial imaging with T2-Prep inversion recovery magnetization preparation.
To develop a magnetization preparation method that improves the differentiation of enhancing subendocardial infarction (MI) from ventricular blood for myocardial delayed-enhancement (DE) magnetic resonance imaging (MRI). ⋯ Our preliminary patient studies confirm that this preparation is helpful for improved delineation of subendocardial infarction.

Image analysis in time-resolved large field of view 3D MR-angiography at 3T.
To qualitatively and quantitatively evaluate the image quality in accelerated time-resolved 3D contrast-enhanced MR angiography (tr-CE-MRA) at 3T. ⋯ Large field of view tr-CE-MRA enables constantly high-quality thoracic and craniocervical angiographies. In addition, the dynamics of tr-CE-MRA can offer additional information on vascular pathologies.

Apparent diffusion coefficient: prostate cancer versus noncancerous tissue according to anatomical region.
To evaluate diagnostic performance of apparent diffusion coefficient (ADC) in differentiating prostate cancer from noncancerous tissue according to anatomical region. ⋯ Variable ADC in noncancerous tissue according to anatomical region may limit diagnostic performance of ADC for cancer detection.

Minimum detectable change in motor and prefrontal cortex activity over repeated sessions using 3T functional MRI and a block design.
To determine the minimum detectable change (MDC) in functional magnetic resonance imaging (fMRI) measurements of brain activity over repeated sessions with 95% confidence using a block design of tasks. ⋯ fMRI measurements that quantify the strength of activity in response to tasks and centers of mass offer sensitive measurements of change over repeated imaging sessions. fMRI can be used for serial investigations of individual participants using simple motor and cognitive tasks using a simple block design.

Comparative StudyAbility of diffusion-weighted imaging for the differential diagnosis between chronic expanding hematomas and malignant soft tissue tumors.
To evaluate the potential of diffusion-weighted imaging (DWI) in distinguishing chronic expanding hematomas (CEHs) from malignant soft tissue tumors. ⋯ DWI is useful for differentiating between CEHs and malignant soft tissue tumors.
