Water/Fat Separation MR Improves Optical Breast Imaging MR Water/Fat Separation Improves Optical Breast Imaging
Background Optical imaging may be added to MR mammography to provide absolute concentration images of oxygenated and deoxygenated hemoglobin, water, and other endogenous and exogenous molecular agents. This is beneficial because hemoglobin and tissue oxygenation have been shown in several studies to have high specificity to breast cancer [1]. This combined optical/MR instrument has been shown t...
متن کاملImaging Manifestations of Mediastinal Fat Necrosis
Mediastinal fat necrosis (MFN) or epipericardial fat necrosis, as it is commonly referred to in the literature, is a rare self-limiting cause of chest pain of unclear etiology. MFN affects previously healthy individuals who present with acute pleuritic chest pain. Characteristic computed tomography (CT) findings include a fat attenuation lesion with intrinsic and surrounding increased attenuati...
متن کاملCombined fat- and water-suppressed MR imaging of orbital tumors.
BACKGROUND AND PURPOSE The use of a high-resolution T2-weighted MR sequence, which suppresses signal from both fat and water, has been shown to be highly effective for depicting areas of inflammatory damage within the optic nerve. The ability of this sequence to show neoplastic and inflammatory orbital lesions, which may mimic neuritis, is unknown. This study was designed to examine the charact...
متن کاملFat - Suppression MR Imaging of the Orbit 961
The effect of fat suppression on orbital MR imaging was tested by using a derivative of the Dixon method called chopper fat suppression in eight normal volunteers and eight patients with normal conventional orbital MR studies. Chopper fat suppression requires no postacquisition image processing or increased scan time and can be applied through a wide range of n to T2 weighting. In normal orbits...
متن کاملFat Necrosis
Breast fat necrosis is a benign inflammatory process. Although it is often considered idiopathic, breast fat necrosis is usually caused by trauma, and many idiopathic cases are probably due to microtrauma. Trauma leading to breast fat necrosis can result from accidents or clinical treatment. Among accidental agents, injury from safety belts in traffic accidents is common. Iatrogenic agents incl...
