Authors: Seo Y, Shin WB, Bae HW, Yoon JS Abstract PURPOSE: We sought to investigate the effects of Graves' orbitopathy (GO) and orbital decompression on lamina cribrosa depth (LCD) using spectral-domain optical coherence tomography. METHODS: Forty eyes that underwent orbital decompression to relieve compressive optic neuropathy or correct disfiguring exophthalmos in the context of GO were included. Subjects were imaged with spectral-domain optical coherence tomography before surgery and at 1 and 3 months after surgery, at which the examiner measured the LCD (distance from the anterior surface of the lamina crib...

Authors: Fistarol F, De Stavola L, Fincato A, Bressan E Abstract The aim of this study is to evaluate the anatomical characteristics of the posterior region of the mandible and their surgical relevance related to bone harvesting procedures. Fifty retromolar cone beam computed tomography scans were analyzed considering the donor site anatomies. For each site, linear measurements were taken of cross-sectional scans to record perpendicular distances between the mandibular canal (MC) and the vestibular and crestal bone walls. Data showed that the distance from the MC to the vestibular bone wall is lower in the ramus ar...

CONCLUSIONS: Patients with CLP and maxillary hypoplasia have a thicker and more everted lower lip than noncleft controls. Patients with BCLP have a significantly thicker lower lip than those with UCLP. Strain of the lower lip musculature appears to be an important contributor to the development of the cleft lip lower lip deformity. PMID: 31610716 [PubMed - in process]

ChuAbstractFrom the literature, the managements for nephropulmonary fistula were variable. We would like to present our case and review the literature for the best method of care.The common features were 1) infected kidney; 2) ipsilateral lower lobe pneumonia or pleural effusion; 3) sputum and urine culture growing the same organism. Renal gaseous content may not be present on x-ray or even CT scan.The choice of management for the nephropulmonary fistula was diverse. However, conservative management...

Abstract A novel deep learning architecture was explored to create synthetic CT (MRCT) images that preserve soft tissue contrast necessary for support of patient positioning in Radiation therapy. A U-Net architecture was applied to learn the correspondence between input T1-weighted MRI and spatially aligned corresponding CT images. The network was trained on sagittal images, taking advantage of the left-right symmetry of the brain to increase the amount of training data for similar anatomic positions. The output CT images were divided into three channels, representing Hounsfield Unit (HU) ranges of voxels containi...

Conclusion: MDCT provides good results in detecting sinus fat, venous invasion and kidney-confined tumors, but evaluation of perinephric fat remains a difficult task, leading to reduced accuracy in T3a staging. PMID: 31607203 [PubMed - as supplied by publisher]
