New Technology For Lung Cancer Detection

New Technology For Lung Cancer Detection
As you all know, currently lung cancer has a grim prognosis, with only 12-15 percent of patients diagnosed with lung caner living long term. Researchers and physicians all over the world have been trying to device methods to improve lung cancer survival from this bleak looking numbers. Early detection and intervention would improve the outcome in lung cancer as it is in many cancers lung breast cancer. Detecting and treating lung cancer when they are small for example like when they are 3 centimeter or less in size improves the survival to about 75 percent.

As I have previously written in this blog, spiral CT scan is a technique that is capable of detecting lung tumors early. In this type of CT scan, the physician obtains about 500 separate slice images of the chest with very high resolution. This would enable the physician to find small lung tumors, before it may have spread to other organs, much like a mammogram in breast cancer. The problem with spiral CT scan is that, it takes for ever to study the 500 or so slice that the machine produces for one person. Large-scale screening using this technique becomes practically impossible or at least very difficult because of the enormous amount of work involved.

Computer-aided detection (CAD), can theoretically replace much of manpower with the computer technology. The computer-aided system that is available so far has not been very sensitive to do the job without errors, so a large number of false positive results occur with CAD.

Now there is progress in this field. Researchers from University of Oxford Engineering Science department have developed a new technique incorporating a process called Visual Moving Features (VMF) for detecting pulmonary nodules. VMF detects a predefined structure in a subject by analyzing the image based on a representation of the structure constructed across a number of parallel image planes. The method has been tested on results from 12 clinical cases involving a total of 3875 sectional images and 106 lung nodules. The technology was so accurate that, every nodule recognized by a skilled radiologist was detected by the Oxford method.

May be this the technology of the future for early lung cancer detection.

Lung cancer
We engage a never-ending daily struggle to understand and defeat the hidden mysteries of cancer. This is a long and laborious fight, but some moments stand out as grim reminders of the severity of the problem and ruthlessness of the enemy. We recently heard about the sad demise of Peter Jennings, who was the news anchor of ABC News for a long time.
