According to the introduction of Shenguo, the largest medical service platform in the United States, John Hopkins researchers reported that their testing of X-ray inspection and guiding equipment was approved by the US Food and Drug Administration in 2013. The test may also reduce the radiation hazard of liver cancer patients undergoing arterial intervention.
In a report prepared for the December 3rd meeting of the North American Radiological Society's 100th Anniversary Annual Meeting (Abstract #SSM24-02), the researchers described the clinical trial results for the AlluraClarity imaging system. AlluraClarity was invented by Philips Healthcare and tested on 50 liver cancer patients. According to Jean-Francois Geschwind, a professor and medical doctor at the Johns Hopkins University School of Medicine and its Kimmel Cancer Center, Russell Morgan Radiation and Radiology, it uses standard X-rays in arterial interventions. For platform imaging systems, the radiation hazard is reduced by 80%, and the image quality is as clear as the standard system.
Geschwind said that if further research is to affirm the findings of his team, this system platform may be particularly helpful for groups such as those who need repeated treatment, those who are more vulnerable through radiation therapy, and those who implement Conventional treatments such as arterial interventions are also susceptible to radiation exposure.
During the arterial intervention, the physician inserts a thin, soft catheter directly into the blood vessels that deliver nutrients to the tumor, using this route to transport chemotherapy and other drugs. X-ray imaging is used to observe the patient's blood vessels, thereby guiding catheter placement and drug delivery.
Geschwind and his colleagues compared the radiation that 25 liver cancer patients experienced with AlluraClarity imaging during intra-arterial treatment and the radiation experienced by 25 liver cancer patients with the X-ray imaging platform called "Allura" invented by Philips before.
Ruediger Schernthaner, MD, a postdoctoral fellow in the Department of Vascular and Interventional Radiology at Johns Hopkins Hospital, said reducing the radiance on the X-ray imaging platform can reduce exposure hazards, but without special image processing. The image noise rate increases, and the physician cannot perform proper treatment because he cannot see the small tissue structure. "You can compare this to the fact that you took a photo with your mobile phone at night but didn't turn on the flash."
Schernthaner said the AlluraClarity platform uses a range of real-time image processing algorithms for high-quality imaging with low radiated power.
