Real-time adaptive filtering for projection reconstruction MR fluoroscopy

, 2003
Magnetic resonance (MR) imaging has faced a dramatic increase in real-time capabilities over the last years. However, the application of fast pulse sequences still suffers from low signal-to-noise ratios (SNRs), which can be the limiting factor for the ...

The Boston All‐in‐One Medial Patellofemoral Complex Reconstruction: A Combined Medial Patellofemoral Ligament and Medial Quadriceps Tendon Femoral Ligament Dynamic Tensioning Technique Using Allograft

Arthroscopy Techniques, EarlyView.
Abstract Recent anatomical understanding of the medial restraints of the patella has evolved over the last decade with a current focus on the medial quadriceps tendon femoral ligament, a distinct anatomical structure to the medial patellofemoral ligament. These combine to form the medial patellofemoral complex. This technical note describes a technique

Hindfoot Instability Test—Introduction and Validation of an Intraoperative Diagnostic Test of Hindfoot Instability in Deltoid Ligament Injury Associated With Ankle Fractures

Clinical Anatomy, EarlyView.
ABSTRACT The deltoid ligament complex (DLC) is well‐known as an ankle joint stabilizer; however, through the superficial DLC, it also acts at the subtalar joint and helps to maintain the medial longitudinal arch. DLC repair in the presence of an ankle fracture remains a topic of controversy in the current literature.

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Feasibility and Procedural Considerations of Balloon‐Expandable TAVR in Patients With Prior Endovascular Aortic Stent Grafts

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Objectives To evaluate the feasibility and short‐term outcomes of transcatheter aortic valve replacement (TAVR) using balloon‐expandable Sapien valves in patients with prior endovascular aortic stent grafts. Methods We conducted a single‐center, retrospective study of 23 patients with prior endovascular aortic stent grafts who underwent TAVR ...
