Augmented reality system lets doctors see under patients' skin without the scalpel

(University of Alberta) New technology is bringing the power of augmented reality into clinical practice. The system, called ProjectDR, allows medical images such as CT scans and MRI data to be displayed directly on a patient's body in a way that moves as the patient does.

In this study, we assessed the efficacy of EphA3 antibody drug conjugate (ADC) and radioimmunotherapy (RIT) approaches using orthotopic animal xenograft models. Brain uptake studies, using positron emission tomography/computed tomography (PET/CT) imaging, show EphA3 antibodies are effectively delivered across the blood-tumour barrier and accumulate at the tumour site with no observed normal brain reactivity. A robust anti-tumour response, with no toxicity, was observed using EphA3, ADC, and RIT approaches, leading to a significant increase in overall survival. Our current research provides evidence that GBM patients may be...

CONCLUSIONS: Ultra-low-dose CT has a good detection rate for all kinds of stone, even when the fragment size is small. Only small uric acid fragments need higher energy settings in order to be detected. When the stone composition is known after surgery for urolithiasis, the most appropriate CT scan setting could be suggested by the urologist during their follow-up.

This study describes the construction of different scan acquisition protocols for micro-CT system applications. Fully-sampled Feldkamp (FDK)-reconstructed images were used as references for comparison to assess the image quality produced by these tested protocols. The insufficient portions of a sinogram were inpainted by applying a context encoder (CE), a type of generative adversarial network, to the LAIR process. The context image was passed through an encoder to identify features that were connected to the decoder using a channel-wise fully-connected layer. Our results evidence the excellent performance of this novel ap...

We present a case of a suspect splenic hematoma in an anticoagulated patient with an ignored diabetes mellitus, come to our emergency department. Lab tests showed increased CRP and INR, with an incoming hepatorenal syndrome. During the CT-scan the patient became unstable and the hemoglobin decreased. We decided for an emergency explorative laparotomy finding instead purulent collections with no evidence of bleeding, so we drained the pus and performed a splenectomy. After we excluded all the common primary sites of infection, we found out a severe chronic parodontopathy caused by multiple colonies of Candida albicans. KEY ...

Authors: Guo L, Zhang L, Zhao J Abstract Value of computed tomography (CT) scan and diffusion-weighted imaging (DWI) in the diagnosis and treatment of esophageal cancer was investigated. Seventy-eight patients with esophageal cancer treated in Jinan Central Hospital (Jinan, China) from January 2013 to June 2014 were selected. All patients underwent CT scan and DWI examination, and their clinical history data were analyzed. DWI was conducted. The short-term curative effect and the 3-year survival rate of patients in the high apparent diffusion coefficient (ADC) value group and the low ADC value group were compared; ...

DiscussionCBCT is essential for the topographic evaluation of wisdom teeth because of the anatomic particularity they may present. The information CBCT offers on the relationship between various types of impaction and the mandibular canal may be helpful in the formulation of the preoperative plan and in avoiding potential risks during extraction.

Publication date: January 2019Source: Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology, Volume 127, Issue 1Author(s): S. MUTALIK, A. TADINADABackgroundVascular calcifications are often carefully assessed by oral and maxillofacial (OMF) radiologists on cone beam computed tomography (CBCT) scans. This is done because of the risk for cerebral ischemia and legal liabilities. Scans with a large field of view (FOV) often depict both extra- and intracranial carotid calcifications. Because of radiation dose concerns, the FOV is often reduced in certain examinations that tend to show extracranial carotid calcification...
