Detecting blood oxygen level-dependent (BOLD) contrast in the breast.
PURPOSE To develop a robust technique for detecting blood oxygenation level-dependent (BOLD) contrast in the human breast and to evaluate the signal in healthy and malignant breast. MATERIALS AND METHODS The design of this study focused on determining the optimal pulse sequence and stimulus for detecting BOLD contrast in the breast. For this study a single-shot fast spin echo (SSFSE) sequence...

to tumor R2* change. A significant positive correlation observed for tumor microvessel density (r = 0.902, p = 0.003) and inverse correlation observed for tumor size (r = -0.802, p = 0.017). Fig. 2 CD34 staining showing diffuse positive CD34 expression (stained brown, left) and color differentiation of CD34 (black, right) for quantification of tumor microvessel density.

متن کاملDetection of scarred and viable myocardium using a new magnetic resonance imaging technique: blood oxygen level dependent (BOLD) MRI.
BACKGROUND The identification of viable myocardium in patients with impaired left ventricular contraction secondary to coronary heart disease is important clinically as such myocardium is likely to benefit from revascularisation. Blood oxygen level dependent (BOLD) magnetic resonance imaging (MRI) relies on changes in deoxyhaemoglobin concentration under stress for signal generation and could b...
متن کاملT 2 - Prepared TrueFISP Blood Oxygen Level Dependent ( BOLD ) Imaging in an Animal Occlusion Model
Introduction: The blood oxygen level dependent (BOLD) effect is a potential mechanism for clinical measurement of myocardial perfusion reserve. During vasodilation, increased blood flow to the myocardium causes an increase in the venous blood oxygen saturation resulting in an increase in T2* and T2 relaxation times. In the past, cardiac BOLD imaging has been plagued by artifacts caused by low s...
