Contrast-enhanced magnetic resonance angiography.
With technological advances in magnetic resonance angiography (MRA), spatial resolution of 1-mm perforating vessels can reliably be visualized and accurately located in reference to patients' anatomic landmarks without exposing patients to ionizing radiation or iodinated contrast, resulting in optimal perforator selection, improved flap design, and increased surgical efficiency. As their experi...
متن کاملContrast-enhanced magnetic resonance angiography carotid arteries.
Angiography Carotid Arteries To the Editor: We were very interested to read the recent study by Johnston et al1 regarding the use of contrast-enhanced MRA (CEMRA) for carotid stenosis. The authors correctly highlight in their introduction the limitations of many current studies of noninvasive tests. We, however, remain to be convinced that their own study is an adequate reflection of the perfor...
متن کاملContrast-Enhanced Magnetic Resonance Angiography of Carotid Arteries
Background and Purpose—Contrast-enhanced magnetic resonance angiography (CEMRA) is among the newer noninvasive tests used for the evaluation of patients with carotid artery disease. Evidence supporting its utility in routine clinical practice is lacking. Methods—The results of CEMRA were compared with those of catheter angiography in 50 consecutive patients being evaluated for carotid endartere...
متن کاملDiagnosis of congenital obstructive aortic arch anomalies in Chinese children by contrast-enhanced magnetic resonance angiography.
OBJECTIVE The purpose of this study was to evaluate the accuracy of contrast-enhanced magnetic resonance angiography for the diagnosis of congenital obstructive aortic arch anomalies in children and compare it with transthoracic echocardiography and other MR imaging techniques (ECG gated T1-weighted spin-echo imaging and gradient-echo cine imaging). MATERIALS AND METHODS Contrast-enhanced mag...
متن کاملcontrast enhanced magnetic resonance imaging in sacroiliitis
conclusion fs t2 w and ce fs t1 w sequences of axial planes were the most useful sequences in determination of active sacroiliitis. therefore, in patients with renal failure or allergy to contrast media, fs t2 wi can be obtained to detect active sacroiliitis. objectives the aim of this retrospective study was to assess the value of different magnetic resonance imaging (mri) sequences in evaluat...
