    OBJECTIVE: To evaluate the usefulness of novel diffusion-weighted imaging (DWI) findings for diagnosing placenta accreta spectrum (PAS). MATERIALS AND METHODS: This retrospective study included 49 pregnant women with suspected PAS who underwent 1.5 T placental MRI. Diffusion lacunae were defined as intraplacental areas showing hypointensity on DWI and hyperintensity on the apparent diffusion coefficient map. Two radiologists evaluated the number and size of placental lacunae on DWI, and flow void in the diffusion lacunae on T2-weighted imaging. The radiologists also evaluated established MRI features of PAS described in the SAR-ESUR consensus statement. Pearson's chi-square test or Mann-Whitney U test was used to compare findings between patients with and without PAS. Interobserver reliability for DWI and established MRI features was also assessed. Optimal thresholds for the number and maximum size of diffusion lacunae for differentiating PAS from the no-PAS group were determined using receiver operating characteristic curve analyses. RESULTS: Eighteen patients were diagnosed with PAS, and 31 patients with placental previa without PAS. The number and maximum size of diffusion lacunae were significantly larger in patients with than in patients without PAS (p < 0.0001). Combining assessment of the number of diffusion lacunae with assessment of their maximum size yielded a diagnostic performance with sensitivity, specificity and accuracy of 83%, 94% and 90%, respectively. Flow voids within the diffusion lacunae had sensitivity, specificity and accuracy of 88%, 84% and 86%, respectively. CONCLUSION: The number and size of diffusion lacunae, and T2 flow void in diffusion lacunae may be useful findings for diagnosing PAS.

  • Establishment of early detection and treatment assessment of pulmonary hypertension by PC-cine MRI

    Grant-in-Aid for Scientific Research(C)

    Project Year: 2016.04  -  2019.03 

    Investigator(s): Murayamma Sadayuki

    　View Summary

    Phase contrast MRI (PC-MRI) can determine pulmonary hemodynamics noninvasively. Pulmonary hypertension causes changes in pulmonary hemodynamics and is a factor for acute exacerbation and death in interstitial lung diseases (ILD). The purpose of this study was to determine the association between pulmonary hemodynamics measured by PC-MRI and episodes of acute exacerbations and death in patients with ILD related pulmonary hypertension. Reduction in right cardiac output, as detected by PC-MRI, was associated with acute exacerbation and increased mortality in ILD. MR examination to detect right ventricular dysfunction is useful for predicting the poor prognosis in fibrotic ILD patients, even if they are not combined with pulmonary hypertension.

    　View Summary

    We collected CT and genetic data from about 1000 individuals. Humans from cold/dry climate tend to possess a relatively tall, narrow, and deep nasal cavity compared with those from warm/humid environment, though the posterior choanal shape lacks such a north-south cline. The individuals with more chiseled feature have more recessed eyeballs (against orbital openings), more protruded facial cranium, thicker skin, and possibly smaller eyeball size. Using lateral cephalometric images, the Ryukyuan females clearly have the following features: 1) a shallower mandibular notch, 2) an anterior-inclined symphysis of mandible, and 3) a smaller depth from upper lip to incisors. We observed a significant association of crown size with an SNP in WNT10A (rs7349332), indicating that common variations in WNT10A have pleiotropic effects on the morphology of ectodermal appendages. We continue genome-wide search for genetic factors associated with 3D facial morphology.
