To compare magnetic resonance imaging (MRI) of the calf with venography for patients with suspected calf deep venous thrombophlebitis (DVT).
Ten consecutive adult patients with suspected calf DVT received venography and, within 48 hours, MRI scans. The tests were reviewed blindly by two radiologists, and results of the tests were compared.
The emergency department of a large teaching hospital with an annual census of 60,000 patients.
All patients with negative venograms had no suggestion of DVT on MRI scan. Two of these patients had other significant demonstrable abnormalities. Four of the five patients with positive venograms had positive calf MRI scans. One patient with a venogram that was difficult to interpret had no DVT on MRI. A thigh DVT was seen on his venogram and was suggested by MRI findings.
MRI may replace ascending venography as the standard for diagnosis of calf DVT.
比较小腿磁共振成像(MRI)与静脉造影对疑似小腿深静脉血栓形成(DVT)患者的诊断价值。
连续10例疑似小腿DVT的成年患者接受静脉造影,并在48小时内进行MRI扫描。两位放射科医生对检查结果进行盲法评估,并比较检查结果。
一家大型教学医院的急诊科,年接诊量为60000例患者。
所有静脉造影阴性的患者在MRI扫描中均未提示DVT。其中2例患者有其他明显的可证实的异常。5例静脉造影阳性的患者中有4例小腿MRI扫描阳性。1例静脉造影难以解释的患者MRI检查未发现DVT。其静脉造影显示大腿有DVT,MRI检查结果也提示了这一点。
MRI可能取代上行静脉造影成为小腿DVT诊断的标准。
