Hemodialysis: Creating the AV fistula using catheters

08/09/2016

For many patients, the start of hemodialysis marks the lifelong dependency on needing their blood purified. But before they can actually begin treatments, a blood vessel in the patient's arm needs to be enlarged to where it can move enough blood and withstand being connected to the dialysis machine several times per week.

Hybrid Operating Room: The OR of the Future Today?

01/09/2016

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.

Intraoperative imaging – added benefit or high-tech gadget?

01/09/2016

Monitoring individual results during surgery with an angiography system? This is already an option in approximately 200 hospitals in Germany. Thanks to intraoperative imaging, major medical procedures can be replaced by minimally invasive surgery because physicians are able to monitor the results immediately. This is gentler on patients and decreases the number of subsequent revision surgeries.

OR of the future: technology benefits surgeons

01/09/2016

When it comes to the future of medicine, we often ponder how we would like to be treated. On the other hand, there is the issue of how physicians would like to treat their patients. The surgical procedures are determined by the technology that doctors are surrounded by. That’s why technology development also needs to be adapted to the needs of surgeons in the operating room of the future.

Cardiac insufficiency: early diagnosis with ultrasound

02/05/2016

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.

An incubator suitable for MRI scans

01/03/2016

Every little thing can be a matter of life or death for premature babies. That is why the right diagnosis plays an extremely important role. This includes examining infants with an MRI scan. Until now, sliding premature babies into an MRI scanner without an incubator was only possible to a limited degree. Now this problem could be solved.

Ultrasound: four dimensions for pediatric cardiac diagnostics

01/03/2016

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.

Theranostics: Complex particles for tomorrow's medicine

01/10/2015

It is a portmanteau, a mixture of two words. This way it saves us time and trouble while speaking because the human speech apparatus is lazy. And it describes a mixture of procedures: the combination of two procedures that would normally be separate in medicine. We are talking about theranostics.

Small companions: How wearables change our lives

01/09/2015

They can be seen everywhere: at the wrists, in the ear, clipped to the belt. Wearables are small technical assistants who are built to collect and partially also to analyze data. Some of them collect measurable health data, others "only" count their user’s steps or measure the surrounding UV radiation. The fact is, however, that wearables are en vogue and are used for many different cases.

Fast and low radiation exposure: The newest generation gamma camera

03/08/2015

Nuclear medicine physicians use so-called gamma cameras for myocardial perfusion scintigraphy. The devices record radioactive substances that are injected into the patient and show changes in the heart muscle (myocardium). Now a new gamma camera is able to record images faster and by using much less radiation.

Prostate cancer: Agent with theranostic potential

03/08/2015

Endoradiotherapy can be very unpleasant for cancer patients, since it does not only harm tumor cells, but also healthy ones. Sometimes, patients even need to stop therapy because of the side effects. Physicians and researchers are thus continuously searching for ways to transport radiopharmaceuticals directly and exclusively to their target.

Radiopharmaceuticals: Individualized diagnostics and therapy

03/08/2015

Malignant tumors can be fought with X-rays – usually with radiation therapy from outside the body. Nuclear medicine physicians can also accomplish this inside the body with radioactive materials, called radiopharmaceuticals. They also offer big benefits for clinical diagnostics as long as a specific target can be assigned to them.

Making the invisible visible with fluorescence

22/06/2015

Bladder tumors have different growth characteristics. In most cases, they are limited to the inner wall of the bladder and thus well resectable. Unlike carcinoma in situ, which becomes muscle invasive after a certain amount of time. To be able to completely remove the tumor during resection, photodynamic diagnostics (PDD) can make sense.
