Star-trail artifacts of the advanced-putrefied brain on postmortem CT
2021
Abstract We report star-trail artifacts of advanced-putrefied brain on postmortem CT (PMCT) of a 77-year-old male approximately one month after death. After CT calibration, routine PMCT (tube current time product: 400 mAs) showed star-trail artifacts, which arose due to cerebral cavitation, but were hardly visible on low-dose PMCT (100 mAs) due to noise. Low-dose PMCT with 4-time-image summation also showed star-trail artifacts. Those are not due to mechanical X-ray detector problems.
