To determine the accuracy of gradient recalled echo magnetic resonance imaging in assessing deep venous thrombosis.
This is a retrospective review of a prospective clinical experience in 216 consecutive patients studied using gradient recalled echo magnetic resonance imaging. Sixteen patients were unavailable for follow-up and 1 study was technically suboptimal, leaving 199 studies as the basis of this report.
In 79 cases with confirmatory venography (n = 54), ultrasound (n = 16, thigh veins only), or computed tomography (n = 9, pelvic veins only), magnetic resonance imaging was 97 percent sensitive, 95 percent specific, and 96 percent accurate. Including cases that were normal by magnetic resonance imaging, not anticoagulated, and with uneventful follow-up as true normal cases, the corresponding sensitivity, specificity, and accuracy of magnetic resonance imaging were as follows: 97 percent, 98 percent, and 97 percent.
Magnetic resonance imaging, using gradient recalled echo acquisitions, is capable of accurately diagnosing acute deep venous thrombosis.
确定梯度回波磁共振成像在评估深静脉血栓形成中的准确性。
这是一项对连续216例使用梯度回波磁共振成像进行研究的前瞻性临床经验的回顾性研究。16例患者无法进行随访，1项研究在技术上不理想，因此本报告以199项研究为基础。
在79例经静脉造影证实（n = 54）、超声检查（n = 16，仅检查大腿静脉）或计算机断层扫描（n = 9，仅检查盆腔静脉）的病例中，磁共振成像的敏感性为97%，特异性为95%，准确性为96%。将磁共振成像显示正常、未接受抗凝治疗且随访过程顺利的病例视为真正的正常病例，磁共振成像相应的敏感性、特异性和准确性如下：97%、98%和97%。
使用梯度回波采集的磁共振成像能够准确诊断急性深静脉血栓形成。
