Noncontrast Magnetic Resonance Lymphography.

BACKGROUND Different imaging techniques have been used for the investigation of the lymphatic channels and lymph glands. Noncontrast magnetic resonance (MR) lymphography has significant advantages in comparison with other imaging modalities. METHODS Noncontrast MR lymphography uses very heavily T2-weighted fast spin echo sequences which obtain a nearly complete signal loss in tissue backgroun...

Coronary magnetic resonance angiography.

Coronary magnetic resonance angiography (MRA) is a powerful noninvasive technique with high soft-tissue contrast for the visualization of the coronary anatomy without X-ray exposure. Due to the small dimensions and tortuous nature of the coronary arteries, a high spatial resolution and sufficient volumetric coverage have to be obtained. However, this necessitates scanning times that are typical...

Magnetic Resonance Angiography Techniques

68 Introduction MR Imaging (MRI) depends on relaxation times T1 and T2 and spin density r. Furthermore, MRI is very sensitive to motion resulting in a variety of flow effects. On one hand, flow effects are responsible for a number of artifacts which can drastically impair the diagnostic value of the images; on the other hand, flow effects can be used advantageously to develop non-invasive techn...
