This is especially common on MR scanners equipped with smaller radiofrequency (RF) transmit coils. A high\u2010performance compact 3T (C3T) scanner features a smaller RF\u2010transmit coil (inner diameter 37\u00a0cm, length 40\u00a0cm), leading to a rapid fall\u2010off of the B1 field below the neck. This configuration results in more intense flow\u2010related ghost artifacts, especially in younger patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose<\/jats:title>\n                    <jats:p>The C3T scanner's smaller RF\u2010transmit coil provides RF field coverage over the brain region, causing bright in\u2010flow arterial signals and flow\u2010related artifacts in the conventional 3D\u2010MPRAGE scans. The purpose of this study is to suppress these artifacts by adding a RF saturation band (RFSB) pulses to the 3D\u2010MPRAGE sequence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The RFSB was added to the 3D\u2010MPRAGE sequence as a preparation pulse option. To test the effectiveness, 37 subjects were scanned on the C3T under an IRB\u2010approved protocol using 3D\u2010MPRAGE with and without RFSB. Ten of those subjects underwent repeated scans with and without RFSB to evaluate test\u2010retest reliability. A consensus evaluation by two neuroradiologists was performed on all data to compare signal to noise ratio, image contrast, presence of artifacts, and diagnostic confidence. Quantitative analysis included calculating test\u2010retest differences by image subtraction and evaluating the variance in flow\u2010artifact\u2010induced image intensity between the scans with and without RFSB. Additionally, one subject was scanned on a whole\u2010body 3T scanner using a transmit\/receive (T\/R) head coil to demonstrate the method's applicability across different MRI platforms as a proof of concept.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The Wilcoxon signed\u2010rank test of the neuroradiologist evaluations showed a significant reduction in artifacts and an improvement in diagnostic confidence in the posterior fossa region with and without RFSB (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.0001). Test\u2013retest analysis showed that adding RFSB significantly reduced image intensity variability in the cerebellum, even among subjects without visible flow artifacts. The normalized difference decreased from 8.71% to 6.41% (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.0059), suggesting improved image reliability in regions prone to flow\u2010related artifacts. Additionally, similar findings were observed in scans on a whole\u2010body 3T with a T\/R head coil, demonstrating the broader applicability of this method.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Incorporating RFSB into 3D\u2010MPRAGE scans effectively reduces flow\u2010related ghost artifact on the C3T scanner, improving image quality and diagnostic confidence. These findings suggest that the proposed method could be widely implemented across MRI systems utilizing a smaller RF\u2010transmit coil.<\/jats:p>\n
