Leonardo da Vinci was right all along, new medical scans show

Leonardo da Vinci’s anatomical drawings were “startling” in their accuracy, new medical scans have shown, putting him hundreds of years ahead of his peers.

He has long been praised as one of the finest artists of the Renaissance, working far ahead of his time and producing some of the world’s most recognisable works. But Leonardo da Vinci has finally received the credit he deserves for his “startling” medical accuracy hundreds of years in advance of his peers, as scientists match his anatomical drawings with modern day MRI scans. The project, which will be unveiled at the Edinburgh International Festival in August, compares the work directly for the very first time, unveiling the minute details recorded by the artist. In a series of 30 pictures, the Royal Collection Trust will show da Vinci’s distinctive anatomical drawings alongside a newly-taken MRI or CT scan. The comparison is intended to show just how accurate da Vinci was, despite his limited technology and lack of contemporary medical knowledge.

Ever since it was approved by the Food and Drug Administration in 2005, robotic surgery for hysterectomy has been heavily advertised. Surgeons promise that using the da Vinci robotic device will bring better results and an easier recovery, and many hospitals claim that patients will experience less pain and fewer complications, getting back on their feet faster.

The company that makes da Vinci robotic surgery equipment promoted it last May at free health workshops organized by the federal Office on Womens’ Health. On Sunday, the Liberty Science Museum in Jersey City will host its first “Let’s Operate Day,” offering guests “hands-on” practice peering into video monitors and using da Vinci’s robot arms to pick up and manipulate small objects.

The cost of the new technology is rarely mentioned. But last week, a new study that evaluated outcomes in more than a quarter of a million American women raised questions about the manufacturer’s claims. The paper, published in The Journal of the American Medical Association, compared outcomes in 264,758 women who had either laparoscopic or robotically assisted hysterectomy at 441 hospitals between 2007 and 2010. Both methods are minimally invasive and involve smaller incisions than open abdominal surgery.

The researchers found no overall difference in complication rates between the two groups, and no difference in the rates of blood transfusion, even though one of the claims regarding robotic surgery is that it causes less blood loss.

But the researchers did find a big difference in cost. Robotically assisted surgery for hysterectomy costs on average about one-third more than laparoscopic surgery. (via Questions About a Robotic Surgery - NYTimes.com)
