Exploration of time sequential, patient specific 3D heart unlocks clinical understanding.

Objectives: The purpose was to create a time sequential three-dimensional virtual reality model, also referred to as a four-dimensional model, to explore its possible benefit and clinical applications. We hypothesized that this novel solution allows for the visuospatial benefits of the 3D model and the dynamic benefits of other existing imaging modalities.

Background: We have seen how 3D models hold great value in medical decision making by eliminating the variable visuospatial skills of practitioners.

Effect of intraparenchymal blood patch on rates of pneumothorax and pneumothorax requiring chest tube placement after percutaneous lung biopsy.

Objective: The purpose of this study was to determine whether an autologous intraparenchymal blood patch reduces the rate of pneumothorax and the rate of pneumothorax requiring chest tube placement after percutaneous lung biopsy.

Subjects And Methods: A prospective randomized controlled trial enrolling 242 patients was conducted. Adult patients undergoing percutaneous biopsy of lung or mediastinal lesions of undetermined cause were candidates.
