Three-dimensional phase-contrast MR angiography in the head and neck: preliminary report.
Morbidity and possible mortality associated with contrast angiography lead to its cautious use. A noninvasive method for screening and further delineating known abnormalities would be welcomed. This article reviews the initial results and application of MR imaging to vascular imaging in the head and neck. By using the three-dimensional phase-sensitive method of Dumoulin, Souza, and collaborator...
متن کاملCoronary CT versus MR angiography: the role of MR angiography.
q RSNA, 2011 Coronary artery disease (CAD) is the most frequent cause of death in many developed countries ( 1 ), and there is a strong need for a noninvasive test that can reliably be used to delineate CAD without the use of ionizing radiation. Coronary magnetic resonance (MR) angiography has a history of nearly 20 years, and considerable technical advances have been made during this period ( ...
متن کاملBrain death: MR and MR angiography.
SUMMARY Four patients in whom brain deaths was identified on the basis of neurologic and electroencephalographic findings were examined with MR imaging and MR angiography. MR images showed diffuse swelling of the cerebral gyri and cerebellar cortex, which prolongation of both the T1 and T2 signal (representing hypoxic ischemic brain injury), downward displacement of the diencephalon and the bra...
متن کاملNonenhanced MR Angiography of the Femoral Head using Time-SLIP
Purpose Observation of blood supply to the femoral head is significantly important when interruption occurs such as a femoral neck fracture, which easily leads to avascular necrosis (AVN) or transient bone marrow edema. However, the observation of blood supply to the femoral head is anatomically difficult due to their small size and amount of blood supply. Today, observation of the feeding arte...
متن کاملThree - dimensional MR microscopy of snowpack structures
A magnetic resonance microscopy technique was developed to visualize and quantify the three-dimensional structure of snowpack. Because the NMR signal from the ice was very weak, we looked at the air space in the snow that was filled with dodecane doped with iron acetylaetonate. Four types of snow were tested: ice spheres, large rounded poly-crystals, small rounded mono-crystals and depth hoar c...
