On left ventriculography a massively dilated left atrium with dimensions of 14 脳 15 cm was observed (Fig. 1). Interestingly, the size of the giant left atrium was approximately five times larger than that of the left ventricle. Coronary angiogram was normal. He underwent open heart surgery ...

extravascular water within an imaging slice so that the strongest remaining signal arises from intravascular water that flows into the slice during image acquisition. This can then be used to generate an angiogram. As noted below,angiographyis particularly useful for assessingvascular occlusionin perinata...
that MCA stem occlusions may be atheromatous as well as embolic. Recanalizing embolus may mimic all the angiographic features of atherosclerosis.140Only when a second angiogram is performed within days of the angiogram demonstrating occlusion (and the initial occlusion is gone) can a diagnosis of ...
Both early-phase (within approximately 1 min) and late-phase (after approximately 5 min) fundus angiograms were acquired. Pentobarbital sodium (i.v., approximately 10-80 mg/monkey) was given to animals to maintain anesthesia during the study process. After the operation, 1-2 drops of...
However, medical images such as biplane angiograms could be exploited for clinically relevant simulation studies. We developed a simulation system that would allow physicians to assess a patient's hemodynamic state. This paper describes the automatic image-based generation of a mesh that is required ...
Further image study showed diminished unilateral kidney size, but the computed tomographic angiogram was unremarkable. Radionuclide renography disclosed a specific pattern of compromised unilateral renal function after captopril challenge, suggesting a high probability of renal artery stenosis. Renal artery ...

95 The application of electrocardiographic gating, while interrogating the flow-related enhancement of spins into a partially saturated area, provides a time of flight (TOF) angiogram.96,97 In a multicenter study, the diagnostic accuracy of TOF MRA was comparable in patients with PAD to that in ...
