Neusoft Medical Systems Co., Ltd. - NeuViz 64 Multislice CT Scanner System - Class 2 Recall

NeuViz 64 Multi-slice CT Scanner System Product Usage: The Multi-Slice CT Scanner System can be used as a whole body computed tomography x-ray system featuring a continuously rotating x-ray tube and detector array. The acquired x-ray transmission data is reconstructed by computer into cross-sectional images of the body from either the same axial plane taken at different angles or spiral planes taken at different angles.

It follows acute mechanical trauma affecting the temporary incisor. This anomaly of shape is characterized by an angulation between the crown and the root of the permanent tooth. The prognosis may be serious because the affected toot...

OliveiraAbstractA Kefiran-based scaffold was developed using a freeze gelation technique, and its potential use for both drug delivery system and tissue engineering applications were investigated. This scaffold showed, through micro-computed tomography and scanning electron microscopy, high porosity (82.3 ± 4.4%), thick pore walls (13.4 ± 0.7 μm), aerogel form with foam-like struct...

Lung cancer has the highest mortality of all cancers in the United States. The incidence of lung cancer with metastases to the skin varies between 1 –12%, with the highest incidence seen in men. Here, we present two cases of lung cancer presenting as skin metastasis. The first patient was an 80-year-old African American male who presented to the hospital for evaluation of a right upper back mass. A few months prior to admission, he was found t o have a left lung mass on CT scan of the chest, he underwent biopsy which showed poorly differentiated SCC of the lung. He also had a skin biopsy which showed poorly different...

Late recurrence of estrogen receptor (ER) positive breast cancer is common. When tissues from a recurrent or metastatic focus are available, re-evaluation of ER, progesterone receptor (PgR), and human epidermal growth factor receptor 2 (HER2) status is recommended for treatment selection. This case report describes a 59-year-old woman who underwent surgery for left breast cancer, with a histopathological diagnosis of invasive ductal carcinoma (pathological stage T2N1aM0 Stage IIB, ER positive, PgR positive and HER2 negative). A health check-up 16 years after surgery revealed multiple hepatic mass lesions, and the patient w...

Study Design. Retrospective multicenter study. Objective. Analysis of impact of conservative and surgical treatments on functional outcome of geriatric odontoid fractures. Summary of Background Data. Treatment of odontoid fractures in aged population is still debatable. Methods. One hundred fourty-seven consecutive odontoid fractures in elderly patients were classified according to Anderson-D’Alonzo and Roy-Camille classifications. Philadelphia type collar was always positioned and kept as a treatment whenever acceptable. Halo-vest, anterior screw fixation, C1–C2 posterior arthrodesis, and occipito-c...

Publication date: Available online 24 June 2019Source: Materials TodayAuthor(s): Thomas M.M. Heenan, Chun Tan, Jennifer Hack, Dan J.L. Brett, Paul R. ShearingAbstractOver the last century, X-ray imaging instruments and their accompanying tomographic reconstruction algorithms have developed considerably. With improved tomogram quality and resolution, voxel sizes down to tens of nanometers can now be achieved. Moreover, recent advancements in readily accessible lab-based X-ray computed tomography (X-ray CT) instruments have produced spatial resolutions comparable to specialist synchrotron facilities. Electrochemical energy c...

In this study, we finalize extensive experiments to appraise the image restoration performance at different levels of tube current and spatial and temporal resolution scales. The results demonstrate the capability of our STIR-Net to restore high-quality scans at as low as 11% of absorbed radiation dose of the current imaging protocol, yielding an average of 10% improvement for perfusion maps compared to the patch-based log likelihood method.
