Talent, magic, or a bit of both?

The science behind Michael Jackson’s dance moves

When was the last time you watched a Michael Jackson music video? If your answer is “never” or “not for quite a while,” you are really missing a treat. According to Rolling Stone, “No single artist … shaped, innovated or defined the medium of ‘music video’ more than Michael Jackson.” Back in the 1980s and early 1990s, MTV had only one format—music videos—and that genre…

Neurosurgical operating theatre

Neurosurgery taught via Virtual Reality

Virtual Reality (VR) technology is aiding trainee surgeons to practise complex procedures in a simulated setting, rather than learning skills on real patients. VR is also helping to demystify neurosurgery in that it enables medical students and patients to ‘enter’ and experience a neurosurgical operating theatre. Alex Alamri, a trainee neurosurgeon at Barts Health NHS Trust in London, UK,…

Brain metastases: Multidisciplinary care improves outcomes

New data reveals the life expectancy of patients with kidney cancer that’s traveled to the brain has now stretched from months to years. UT Southwestern Kidney Cancer Program investigators report survival rates beyond 2.5 years for some patients with specialized multidisciplinary care. Historically, patients whose kidney cancer had spread to the brain were believed to have only about six months…

Laughter may be best medicine for brain surgery

Neuroscientists at Emory University School of Medicine have discovered a focal pathway in the brain that when electrically stimulated causes immediate laughter, followed by a sense of calm and happiness, even during awake brain surgery. The effects of stimulation were observed in an epilepsy patient undergoing diagnostic monitoring for seizure diagnosis. These effects were then harnessed to help…

Virtual assistance during procedures

The adage ‘practice makes perfect’ is applicable to every profession – but even more so for pilots and surgeons. Flight simulation technology has been used for decades to hone aviators’ skills, and this technology is now being used by neurosurgeons to plan as well as practise surgical procedures and for real-time virtual assistance in operating theatre.

Optical Coherence Tomography

Removing brain tumor safer

Brain surgery is famously difficult for good reason: When removing a tumor, for example, neurosurgeons walk a tightrope as they try to take out as much of the cancer as possible while keeping crucial brain tissue intact — and visually distinguishing the two is often impossible. Now Johns Hopkins researchers report they have developed an imaging technology that could provide surgeons with a…

Study asks neurosurgeons

How old is too old to perform brain surgery?

People sometimes joke that easy tasks are “not brain surgery.” But what happens when it actually is brain surgery? How old is too old to be a neurosurgeon? In a new Mayo Clinic Proceedings study, most neurosurgeons disagreed with an absolute age cutoff, but half favored additional testing for neurosurgeons 65 and older. Some professions, including commercial pilots, FBI agents and air traffic…

Intra-operative imaging in modern neurosurgery

The brain has few anatomical landmarks. During surgery it is critical that the neurosurgeon knows the exact locality of surgical instruments in relation to important brain structures. Thus neuronavigation systems have become standard tools for planning and guidance.

Stereotactic radiosurgery

Italy - The latest advance in stereotactic radiosurgery - the Leksell Gamma Knife Perfexion made by Elekta, is due for inauguration this month at the Neurosurgery Department in Niguarda Hospital, located in the northern area of Milan. This prestigious hospital employs over 700 physicians and 1,500 nurses, and over 50,000 patients are admitted annually, and over 20,000 surgical procedures are…

Radiologists must change or lose out

With cardiologists and neurologists purchasing imaging equipment for use by them in their departments, clinical education has become crucial to the survival of radiologists, for whom specialist training, with a focus on particular body areas, is also imperative, says radiological interventionist Professor Malgorzata Szczerbo-Trojanowska, President of the ECR 2010.

Conjoined twins successfully separated

Twin girls born joined at the pelvic and hip region are recovering after separation surgery at Nationwide Children’s Hospital. The girls are named Acen and Apio, but on Thursday they were carefully labeled “blue” and “red” to help surgeons know which monitoring equipment belonged to each sister as they carefully separated their spines, muscle and tissue.

Closing in on the brain

The new Nextim system, eXimia NBS is a novel brain stimulation technology which provides individual measures of the health and functional capacity of the central nervous system, as well as of brain reactions to targeted magnetic pulses. Thanks to its advanced technology and proven clinical performance, the NBS system helps medical professionals to focus on the issues that matter the most - and to…

Forging links between neurology and surgery

Surgery in the lower pelvic region often involves injury to or severing of nerve tissue. As in chronic diseases of the nervous system, the result can be pain, sensory disturbances or loss of function. Up to now the poor view of the nerves, partially formed of fine interwoven networks, has been one of the major problems – exacerbated by the strict division of skills between neurologists and…

The Novalis Tx for stereotactic radiosurgery

Novalis Tx, a system for stereotactic radiosurgery, has resulted from a partnership between the Munich-based medical technology company BrainLAB AG and Varian Medical Systems Inc, two firms that have successfully worked together on radiation therapy products for over a decade. The powerful linear accelerator Trilogy Tx and special technology for beam focusing was contributed by Varian; BrainLAB,…

Image-Guided Neurosurgery Suite at Barrow Neurological Institute

GE Healthcare and Barrow Neurological Institute at St. Joseph's Hospital and Medical Center implementet a MR-guided intra-operative surgical suite. This new system includes one of the world's most comprehensive portfolio of neuro-imaging solutions, which uses three-dimensional imaging to navigate and validate treatments to help increase both the accuracy and speed of interventions while improving…

The multi-window monitor for interventional imaging

Necessity is the mother of invention, an old saying but particularly true in interventional radiology. Whenever minimally invasive procedures need monitoring from different angles and by different modalities, physicians and technicians in angio labs muster all their DIY skills and build huge monitor towers often with eight screens. Now, however, the new Large Display jointly developed by Siemens…

Turf wars

Nowadays, no radiology conference would be complete without a discussion on turf battles. The rapid development and broad acceptance of cardiac CT has exceeded expectations, and both radiologists and cardiologists are incorporating this technology into their practices. Educational courses on cardiac CT are in high demand and well attended by both radiologists and cardiologists.

Determining the site of deep brain implants

Uncontrollable convulsions, tremor or spasms can considerably impair the lives of neurodegenerative disease patients. Deep brain stimulation (DBS) – for which tiny electrodes are implanted in the brain to stimulate the target areas continuously with electrical impulses – can significantly reduce the movement disorder.

MRI: Still the best tool for seizures

Anti-seizure medication is not successful in all patients, while in others such medication can have side effects. In recent years significant technical advances have delivered better imaging results, which, combined with growing demand for a surgical solution from patients whose medications do not control seizures, or those not wanting to take medication constantly, has led to an increase in…

9-, 10- or even 11-Tesla – is more always better?

How the brain is organized

The age of exploration has long passed, but there is at least one area still largely uncharted: the human brain. Now, a detailed new map by researchers at Washington University School of Medicine in St. Louis lays out the landscape of the cerebral cortex – the outermost layer of the brain and the dominant structure involved in sensory perception and attention, as well as distinctly human…
