Failure We have read the recent article entitled “Quantification of Thrombus Hounsfield Units on Noncontrast CT Predicts Stroke Subtype and Early Recanalization after Intravenous Recombinant Tissue Plasminogen Activator” by Puig et al with great interest. We congratulate the authors on their analysis, in which they found that relative Hounsfield unit attenuation of MCA clot was the best predict...
Abstract Background The aim of this study was to assess the ability using mean computed tomography (mCT) values predict non-small cell lung cancer (NSCLC) tumor recurrence. Methods A retrospective conducted on 494 patients with stage IA NSCLC. Receiver operating characteristics analysis used use mCT value, C/T ratio, size, and SUV Multiple logistic regression analyses were performed determine i...
This study aimed to develop a prediction model for the operative time of flexible ureteroscopy (fURS) for renal stones. We retrospectively evaluated patients with renal stones who had been treated successfully and had stone-free status determined by non-contrast computed tomography (NCCT) 3 months after fURS and holmium laser lithotripsy between December 2009 and September 2014 at a single inst...
Introduction: Quality assurance in Computed tomography (CT) centers in developing countries are largely hindered by the unavailability of CT phantoms. The development of a local CT phantom for the measurement of organ radiation absorbed dose is therefore requisite. Material and Methods: Local CT phantoms were designed to meet the standard criteria of 32 cm diameter for body, 16 cm diameter for...
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
