Stereoscopic magnification in spinal angiography.
This technique combines the advantages of magnification and stereoscopic angiography. A heavy-duty x-ray tube oscillating between two positions (25 mm apart) allows serial spinal angiograms to be produced in stereo magnification (factor 2.0) using the 0.2 mm, 12 kW focal spot. The x-ray tube can be rapidly changed for normal serial angiography with a 0.6 mm, 50 kW focus. The technique is easy t...
متن کاملMagnification Angiography of Cerebral Aneurysms Associated with Moyamoya Disease
The true cause of intracranial hemorrhage in moyamoya disease has not been clarified. Magnification cerebral angiograms were reviewed for seven patients. In four , small saccular aneurysms were seen arising from abnormally dilated collateral vessels or feeding arteries. This study suggests that aneurysms may be a source of hemorrhage in addition to the generally accepted rupture from abnormally...
متن کاملMacroradiography in 4 times magnification applied to cerebral angiography.
This is the first time that macroradiography in four times magnification has been applied in the field of cerebral angiography. The macroradiography can demonstrate much more clearly the state of branching of the arteries arising from the carotid syphon. In the brain tumor the finer structures of the tumor mass such as tumor stain are well demonstrated. In the arterio-venous fistula the finer c...
متن کاملP-150: Effect of Vitrification on High Magnification Morphology and Fertility Potential of Human Spermatozoa Cell
Background: Many sperm characteristics including, motility and morphology are important for normal spermatozoa- oocyte intraction. These features may be altered during vitrification. Motile sperm organelle morphology examination (MSOME) is an unstained real time high magnification technique that analysis viable sperm morphology instantly. This study aimed to investigate the influence of vitrifi...
متن کاملMagnification pulmonary wedge angiography in the evaluation of children with congenital heart disease and pulmonary hypertension.
In order to determine the presence and extent of obstructive pulmonary vascular disease in patients with congenital heart disease, magnified cineangiograms were obtained with a catheter in the pulmonary artery wedge position in 155 infants and children undergoing cardiac catheterization. The wedge angiograms (WA) were analyzed in groups according to the pulmonary hemodynamics: group A normal pu...
