With extensive experience in the field of neuroradiology, Gul Moonis, MD, serves as a radiologist at Beth Israel Deaconess Medical Center and as an assistant professor of radiology at Harvard Medical School. Dr. Gul Moonis also conducts research and stays abreast of developments in radiology techniques such as temporal bone imaging.
In a recent study published in the American Journal of Neuroradiology, researchers from the Mayo Clinic explored how to reduce radiation exposure and enhance image quality during temporal bone CT imaging. The researchers investigated this topic because the dose of radiation for temporal bone CT is often greater as a result of high spatial resolution requirements. During the study, the researchers sought to determine if there was less image noise and better spatial resolution from the combination of an iterative reconstruction algorithm and an ultra-high-resolution scan mode compared to a z-axis ultra-high-resolution protocol.
After isolating eight suitable patients and 16 pairs of temporal bone images, the researchers compared ultra-high-resolution-iterative reconstruction and paired z-axis ultra-high-resolution images. The researchers concluded that ultra-high-resolution-iterative reconstruction scan mode for CT of the temporal bone offers comparable or somewhat improved resolution in comparison to the z-axis ultra-high-resolution mode while delivering significantly less image noise. According to the study abstract, this could allow the radiation dose to be decreased by about 50 percent.
