Fig. 2From: Black-blood thrombus imaging (BTI): a contrast-free cardiovascular magnetic resonance approach for the diagnosis of non-acute deep vein thrombosisPlots of the apparent CNR versus DANTE pulse train length (PTL). DANTE with 125–175 PTL yields good black-blood effect without considerable signal loss in static tissues. Considering that the venous flow could be even slower in DVT patients, the PTL of 175 was chosen as the optimal parameter for BTIBack to article page
