Use of three-dimensional MR angiography for tracking a contrast bolus in the carotid artery.
نویسندگان
چکیده
Contrast-bolus tracking in the carotid bifurcation was accomplished using an MR angiographic technique with a 3D turbo field-echo readout (TR/TE = 6/3, flip angle = 50 degrees) modified by a keyhole scheme. Optimal visibility of the contrast bolus was achieved by digital subtraction from a reference volume. This technique reliably time-resolves the carotid arteries from the jugular veins.

Introduction: Digital Subtraction Angiography (DSA) is the standard method for detection of carotid artery stenosis. This technique has high radiation dose. With the progress of imaging techniques, noninvasive or minimally invasive methods like the CT angiography, MR angiography and ultrasonography with Doppler or Duplex mode were applicable. This study aimed to evaluate and assesse the results...
متن کاملEvaluation of strain and strain rate parameters using two-dimensional speckle-tracking echocardiography in patients with coronary artery disease (Research Article)
The study aimed was to measure left ventricular (LV) strain using speckle tracking echocardiography (STE) for assessment of LV function. Eighty-two subjects (mean age 57±9 years) with suspected chest pain underwent two-dimensional (2D)-echocardiography before coronary angiography. Conventional echocardiographic parameters were used for the assessment of LV function. Longitudinal strain and its ...
متن کاملTechnique for arterial-phase contrast-enhanced three-dimensional MR angiography of the carotid and vertebral arteries.
Our goal was to evaluate whether contrast-enhanced three-dimensional MR angiography using the MR Smartprep technique would enable us to obtain arterial-phase MR angiograms of the carotid and vertebral arteries. The study included 35 patients with suspected lesions of the neck in whom the MR Smartprep technique was used for MR angiography performed with a 1.5-T superconducting system. The tracke...
متن کامل3DFT MR angiography of carotid and basilar arteries.
Three-dimensional Fourier transform (3DFT) time-of-flight and two-dimensional Fourier transform (2DFT) projection phase-contrast MR angiography was performed in eight healthy volunteers and in 14 patients with known carotid artery or basilar artery occlusion, stenosis, or dissection. Comparative angiography was available in 13 cases (although in some cases the studies were separated by a number...
متن کاملThree-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...
