Hybrid Operating Room: The OR of the Future Today?


Patients take center stage during surgery. Their treatment should be as gentle and effective as possible, which is why there is a trend towards minimally invasive surgery (MIS). But minimal procedures require better supporting technologies. The hybrid operating room combines surgery and imaging systems and increasingly replaces conventional open surgery approaches with MIS.

Gene therapy via ultrasound could offer new therapeutic tool


Combining ultrasound energy and microbubbles to poke holes in cells may prove to be a new tool in the fight against cardiovascular disease and cancer, according to researchers from the University of Pittsburgh and UPMC. A study on this gene therapy approach, called sonoporation, is published in the Proceedings of the National Academy of Sciences (PNAS).

Cardiac insufficiency: early diagnosis with ultrasound


Heart failure or cardiac insufficiency presents an extra strain on patients because it severally limits everyday performance and deprives them of energy. Due to their intense need for movement, children are particularly strongly affected. However, the disease is frequently not detected until the physical performance is already declining. An early diagnosis could prevent this.

Ultrasound: four dimensions for pediatric cardiac diagnostics


Fortunately, only a handful of newborns are affected by them, though this determines if not the rest of their lives then, at least, the first few years of affected children: congenital heart defects. After the necessary surgeries, the small patients repeatedly need to return for checkups. Until now, these were conducted using MRI scans. 4D ultrasound can be an alternative.

Fighting myomas with ultrasound


A proper diagnosis is a part of great therapy. However, it can also be beneficial to be able to quickly respond to changes during a treatment. One example of this is the treatment of uterine myomas. Female patients at the University Hospital Bonn are treated using so-called high-intensity focused ultrasound, HIFU in short. Prof. Holger Strunk explains this procedure.

Sonography: "Unfortunately, hospitals are not being required to train well"


Prenatal care, cancer check-up, vascular examinations – sonography is versatile, provides reliable imaging to physicians and does not tax patients with radiation. It is comprehensively available, from doctor’s office to university medical center. A sound continuing education of sonography users is essential for good diagnostics, also since different devices have different strong points.
