动态增强磁共振淋巴造影

磁共振淋巴造影是在被称为XMR组合中进行的，它结合了血管造影设备和MRI

Intranodal injectionn of Gad 经淋巴结钆造影剂注射

After intranodal access, 0.2 mL/kg of nondiluted gadopentetate dimeglumine followed by 2 mL of saline is hand injected simultaneously into the bilateral lymph nodes at a rate of 1 mL/min

建立淋巴结内通路后，以1mL/min的速率，将0.2mL/kg非稀释的钆齿丁酸丁二胶胺，及随后2mL的生理盐水同时注入双侧淋巴结

Imaging acquisition begins 1 min after the start of contrast injection with the following parameters: T1-weighted MR angiography; 3/1; flip angle, 25°; matrix, 320 x 240; field of view, 300-450; section thickness, 1.2 mm; isotropic voxel size, 1.2 x 1.2 x 1.2 mm; time delay for complete volume acquisition every 30-60 sec; total imaging time, 10 minutes2

成像采集在对比注射开始后1分钟开始，参数如下：

T1加权MR血管造影；T1-weighted MR angiography;
3/1；翻转角度，25°； 3/1; flip angle, 25°;
矩阵，320×240； matrix, 320 x 240;
视野，300-450；field of view, 300-450;
isotropic voxel size, 1.2 x 1.2 x 1.2 mm;
截面厚度，1.2毫米；section thickness, 1.2 mm;
time delay for complete volume acquisition every 30-60 sec;
