Risk factors for motion artifacts in fast spin-echo T2-weighted imaging of the prostate magnetic resonance imaging: a retrospective study.
Prostate cancer diagnosis using fast spin-echo (FSE) T2-weight imaging (T2WI) suffers from motion artifacts (T2-MA). We aimed to investigate the risk factors associated with T2-MA. We retrospectively analyzed the basic patient information and localizer images of 168 patients who underwent prostate magnetic resonance imaging at our institution between April 2019 and December 2021. FSE T2WI image quality was classified into Poor, Acceptable, and Excellent groups based on T2-MA severity. Between-group differences were analyzed using the Kruskal-Wallis test, and multinomial logistic regression was used to calculate adjusted odds ratios (ORs) for T2-MA. The bladder area of the Acceptable group was significantly larger than that of the Poor group (P = 0.010). The rectal area was significantly larger in the Poor group than in the Excellent group (P = 0.013). Larger rectal and bladder areas in the localizer image were significant risk factors for severe (OR: 1.136) and mild (OR: 1.032) T2-MA, respectively.
期刊介绍:
The purpose of the journal Radiological Physics and Technology is to provide a forum for sharing new knowledge related to research and development in radiological science and technology, including medical physics and radiological technology in diagnostic radiology, nuclear medicine, and radiation therapy among many other radiological disciplines, as well as to contribute to progress and improvement in medical practice and patient health care.
