Inclusion criteria
Inclusion criteria: - Patients with confirmed acute SVT; definitions provided in paragraph 4.2 (Cases, group 1) - Patients with confirmed non-symptomatic chronic SVT, defined by incident SVT treated for at least 3 months and with chronic thrombi on 2 serial imaging tests with at least 3 months interval (controls, group 2) - Aged 18 years and older - Willing and able to give informed consent
Exclusion criteria
Exclusion criteria: - MRI contra-indication (including but not limited to a cardiac pacemaker or subcutaneous defibrillator; vascular clips in the cerebral vessels; metal splinter in the eye, a hearing aid that cannot be removed; a neurostimulator that cannot be removed; a hydrocephalus pump) - A medical condition, associated illness or co-morbid circumstances that precludes completion of the study procedures (MRI and 90-day follow-up assessment), including but not limited to life-expectancy less than 3 months, inability to lie flat, morbid obesity preventing use of MR and claustrophobia. - Patients with decompensated liver disease with ascites (since MRDTI evaluation will be inadequate in these patients)
