“…Initial studies used contrast venography as gold standard and found sensitivity and/or specificity values for MRV as high as 100% in diagnosing femoro-popliteal DVT (55)(56)(57)(58). However, it has performed less well than contrast venography in assessing the calf veins.…”

“…Human venous thrombi have been de tected successfully by MRI [10,[17][18][19][20], and the outcome of thrombolytic treatment has been assessed by the same method [21], MRI is the only morphological method so far that can differentiate between retracted and nonretracted clots. Clot retraction hinders clot lysis in vitro, but the proof of the same effect in vivo is still lacking.…”

“…MR images of human venous thrombi showed regional variability in signal intensi ties [10]. This phenomenon was attributed to differences in thrombus age at different loca tions, but could also be explained by different degrees of retraction.…”

Magnetic resonance imaging (MRI) of retracted blood clots embedded in nonretracted clots was used to follow their lysis with urokinase in a plasma milieu in vitro. The two types of clots that were imaged in the same plane differed in signal intensity on T₂-weighted spin echo MR images throughout the 20-hour observation period. It was thus possible to delineate the contours of both clot types and measure their relative sizes by digital image processing. Lysis of retracted clots proceeded significantly slower than lysis of nonretracted clots. Our in vitro results suggest that MRI might prove useful in detecting thrombus retraction in vivo and in predicting the outcome of thrombolytic therapy.

“…In the early 1990s magnetic resonance imaging (MRI) was tested in preliminary studies including those with a small number of patients. [58][59][60][61][62][63] Compared to contrast venography, they suggested that MRI was at least 90% sensitive and specific (review in 53…”

Looking for Deep Vein Thrombosis in Suspected Pulmonary Embolism

Pulmonary embolism (PE) and deep vein thrombosis are two facets of the same disease, that is, venous thromboembolism (VTE). In patients with angiographically proven PE, the prevalence of proximal deep vein thrombosis by venography is around 70%. The sensitivity of compression ultrasonography (US) for the diagnosis of acute VTE in patients with a suspicion of PE is between 40 and 60%, with a high specificity (96 to 100%). Taking into account the 20 to 30% prevalence of PE in a population consulting for suspicion of this disease, the first line use of compression US will allow the diagnosis of acute VTE in half of patients with confirmed PE, that is, in 10 to 15% of patients addressed for suspicion of PE. In outpatients, the first line use of D-dimers which will exclude acute VTE in one-third of the initial population will slightly increase the reliability of compression US as a first imaging test. New tools of looking for deep vein thrombosis, such as computed tomographic venography coupled with computed tomographic pulmonary angiography, could become an interesting approach in the diagnostic strategy of PE, but require adequate evaluation in prospective studies.
