Venous thromboembolism in subarachnoid hemorrhage.

Objective: Venous thrombembolism is a significant cause of mortality in patients after subarachnoid hemorrhage (SAH). After screening a cohort of SAH for this complication, we proposed a refinement for risk stratification of venous thromboembolism.

Methods: Our retrospective study included patients admitted to our academic medical center (2005-2007) for SAH from ruptured aneurysm and having survived beyond 72 hours.

Comparison of magnetic resonance feature tracking for strain calculation with harmonic phase imaging analysis.

Objectives: To compare a steady-state free precession cine sequence-based technique (feature tracking [FT]) to tagged harmonic phase (HARP) analysis for peak average circumferential myocardial strain (epsilon(cc)) analysis in a large and heterogeneous population of boys with Duchenne muscular dystrophy (DMD).

Background: Current epsilon(cc) assessment techniques require cardiac magnetic resonance-tagged imaging sequences, and their analysis is complex. The FT method can readily be performed on standard cine (steady-state free precession) sequences.
