A study of contrast agent peak time using biomechanics factors experimental contrast medium infusion test using at contrast enhanced magnetic resonance angiography

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...

Magnetic Resonance Angiography Using a Blood-Pool Contrast Agent, Gadofosveset

Contrast-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...

contrast 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...

Image Reconstruction with Time-Resolved Contrast Enhanced Magnetic Resonance Angiography

Contrast enhanced magnetic resonance angiography enables one to visualize the vascular system of the human body. Typically, using conventional measurement techniques, one three-dimensional volume of the vascular system can be measured during the passage of the contrast agent. More recently, medical doctors desire time-information of the blood-flow, or want to scan time-dependent phenomena. To e...
