Key result
MR imaging at 0.35 T cannot be used to predict the age of venous thrombi up to 3 weeks, as thrombi appeared hyperintense regardless of age, but may be helpful in following resolution.
Why the study?
Can 0.35-T MR imaging predict the age of venous thrombi or follow its resolution in animal models and patients?
Population
3 laboratory dogs with 5 induced venous thrombi in the external jugular veins, and 13 patients with 19…
Follow-up
up to 4 weeks

Low-field MR should not guide venous thrombus dating; leaves open its potential role in monitoring resolution.

Can 0.35-T MR imaging predict the age of venous thrombi or follow its resolution in animal models and patients?
MR imaging at 0.35 T is not effective for predicting the age of venous thrombi up to 3 weeks, but may assist in monitoring their resolution.
Erdman et al. (1986) conducted an observational in Venous thrombosis (n=13). 0.35-T magnetic resonance (MR) imaging was evaluated on Changes in appearance on MR images with time to predict thrombus age. MR imaging at 0.35 T cannot be used to predict the age of venous thrombi up to 3 weeks, as thrombi appeared hyperintense regardless of age, but may be helpful in following resolution.
