MRI-guided laser treatment for brain tumor performed for the first time in California

UC Health Sciences – an otherwise inoperable brain cancer within the hypothalamus was successfully removed by the medical team led by neurosurgeon Clark C. Chen, MD, PhD, vice chairman of research, UC San Diego Division of Neurosurgery.

Dr. Chen used a technique called laser interstitial thermal therapy. This brain cancer treatment, which is impossible to carry out in a conventional operating room and requires the presence of a trained MRI team, involves the use of an MRI machine while the patient is under general anesthesia. Real time imaging of the brain tissue is used by the neurosurgeon as a guide while inserting a probe into a dime sized hole created on the patient’s skull. The laser probe is then continued on to the location of the tumor and once the mass is reached, the laser beam is stimulated, targeting the tumor cells and destroying it by heat.

“This MRI-guided laser technology helps neurosurgeons preserve healthy brain tissues”, said Chen. He further stated that as accurate as MRI can be in giving detailed images of the brain tissue, noBrain cancert known to everyone is its ability to measure and monitor the internal temperature of the brain. This property of the machine is what Chen used to have a good visualization of the brain tissue while it is being destroyed as well as adjusting the effects of the laser to be able to preserve the surrounding normal brain tissue. After the laser ablation procedure, patients are discharged a day after if without complications and are able to carry on with their activities.

There are several types of tumor cells which can be targeted by this laser technology. According to Chen, it can also be used to destroy anaplastic astrocytomas, glioblastomas, and even brain metastases. Before the procedure is done, the risk-benefit profile of the patient was assessed to be able to choose the best option for the patient’s current condition. Chen adds that his main objective for the procedures is to not only remove the existing mass and treat the individual, but also to provide the best quality of life the patient can have after the process.

  3. Hello Web Admin, I noticed that your On-Page SEO is is missing a few factors, for one you do not use all three H tags in your post, also I notice that you are not using bold or italics properly in your SEO optimization. On-Page SEO means more now than ever since the new Google update: Panda. No longer are backlinks and simply pinging or sending out a RSS feed the key to getting Google PageRank or Alexa Rankings, You now NEED On-Page SEO. So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword….wait there’s even more Now what if i told you there was a simple WordPress plugin that does all the On-Page SEO, and automatically for you? That’s right AUTOMATICALLY, just watch this 4minute video for more information at. Seo Plugin
