Comparative Study
Assessment of extracranial-intracranial bypass in Moyamoya disease using 3T time-of-flight MR angiography: comparison with CT angiography.
To evaluate the value of time-of-flight MR angiography (TOF MRA) for the assessment of extracranial-intracranial (EC-IC) bypass in Moyamoya disease in comparison with computed tomography angiography (CTA). ⋯ 3T TOF MRA, a non-contrast technique not exposing the patients to radiation, proved to be at least equal to CTA for the assessment of EC-IC bypass, and even superior to CTA with respect to the intracranial segment. In addition, readers should be aware of a potential overestimation showing focal pseudo lesions of the bypass at the trepanation segment in TOF MRA.

Cancer is a highly thrombophilic entity leading to a high rate of symptomatic and even asymptomatic venous thromboembolic (VTE) events in patients suffering from malignant disease. As VTE events have impact on survival and can be reduced significantly by anticoagulant treatment, guidelines on prophylaxis of these events by means of anticoagulation exist from various societies. Purpose of this review is to give a concise overview of current possibilities for prophylaxis and also for the therapy of VTE events in cancer patients.
