“…To accomplish this, many studies have reported child-friendly MRI protocols that assist with successful, nonsedated image acquisition for children with cleft/craniofacial conditions. 11,19,34 These perceived barriers for velopharyngeal imaging continue to be consistent with past reports. Witt et al 9 reported on the evolution of velopharyngeal imaging, including the early applications of MRI for this population.…”

“…Furthermore, behavioral protocols have been established to provide support for successfully imaging children as young as 4 years of age. 19,45 Considering the increase in research surrounding the use of MRI for this population over the past 2 decades, the value and potential of MRI as a diagnostic tool for velopharyngeal function is becoming apparent. Mason and Perry 11 discuss the underlying principles of MRI, describe the advantages and disadvantages of MRI for this population of patients, and discuss a standard protocol for assessing velopharyngeal anatomy.…”

“…As a result, many clinical implications for use of MRI with cleft and craniofacial diagnostics have been proposed. 10,[13][14][15][16][17][18][19][20][21][22][23][24][25] However, the use of MRI in the assessment process for children with cleft and craniofacial conditions remains uncommon in clinical practice on cleft and craniofacial teams, both in its general use by providers on craniofacial teams and particularly for velopharyngeal assessments. Specifically, there has been little systematic discussion of the barriers many clinicians may face when considering the implementation of MRI for clinical practice for this population of patients.…”

Objective The use of magnetic resonance imaging (MRI) in the assessment process for children with cleft/craniofacial conditions remains uncommon, particularly for velopharyngeal assessments. The purpose of this study was to analyze the perceived clinical utility of MRI for cleft/craniofacial providers and identify barriers that exist for clinical translation of this imaging modality to this population of patients. Methods A 38-item survey was disseminated to craniofacial team providers. Workplace context and demographics, MRI as a research and clinical tool, access and barriers for use of MRI, and needs for successfully establishing MRI protocols at clinical sites were investigated. Descriptive statistics were used to identify differences in the clinical use of MRI across disciplines. Chi-square analyses were conducted to determine how different specialties perceived potential barriers. Results Respondents reported that MRI is likely to be beneficial for clinical assessments (93.5%) and that this imaging modality is available for use (83.8%). However, only 11.8% of providers indicated the use of MRI in their clinical assessments. This discrepancy highlights a potential disconnect between perceived use and implementation of this imaging methodology on cleft and craniofacial teams. A number of barriers were identified by providers. Challenges and opportunities for clinical translation of MRI protocols were highlighted. Conclusion Results may guide the development for improved clinical feasibility and implementation of MRI for clinical planning in this population of patients. Reported barriers highlight additional areas for translational research and the potential for the development of clinical tools related to MRI assessment and protocol implementation.

PurposeTo improve the spatiotemporal qualities of images and dynamics of speech MRI through an improved data sampling and image reconstruction approach.MethodsFor data acquisition, we used a Poisson‐disc random under sampling scheme that reduced the undersampling coherence. For image reconstruction, we proposed a novel locally higher‐rank partial separability model. This reconstruction model represented the oral and static regions using separate low‐rank subspaces, therefore, preserving their distinct temporal signal characteristics. Regional optimized temporal basis was determined from the regional‐optimized virtual coil approach. Overall, we achieved a better spatiotemporal image reconstruction quality with the potential of reducing total acquisition time by 50%.ResultsThe proposed method was demonstrated through several 2‐mm isotropic, 64 mm total thickness, dynamic acquisitions with 40 frames per second and compared to the previous approach using a global subspace model along with other k‐space sampling patterns. Individual timeframe images and temporal profiles of speech samples were shown to illustrate the ability of the Poisson‐disc under sampling pattern in reducing total acquisition time. Temporal information of sagittal and coronal directions was also shown to illustrate the effectiveness of the locally higher‐rank operator and regional optimized temporal basis. To compare the reconstruction qualities of different regions, voxel‐wise temporal SNR analysis were performed.ConclusionPoisson‐disc sampling combined with a locally higher‐rank model and a regional‐optimized temporal basis can drastically improve the spatiotemporal image quality and provide a 50% reduction in overall acquisition time.
