Publication date: Available online 18 April 2019Source: NeurocomputingAuthor(s): Pengyi Hao, Kun You, Haozhe Feng, Xinnan Xu, Fan Zhang, Fuli Wu, Peng Zhang, Wei ChenAbstractEarly detection of lung cancer is the most promising path to increase the chance of survival for patients. Accurate lung nodule detection in computed tomography (CT) images is a crucial step in diagnosing lung cancer. CNN based CADe systems diagnose lung nodules in two stages by using one network for detection and another following network for classification or false positive reduction. Besides costly construction, two-stage systems can only find a sin...

Authors: Simsek FS, Arslan M, Dag Y Abstract In some non-small cell lung cancer (NSCLC) patients, lipid-poor adrenal adenomas cannot be adequately differentiated from metastases using imaging methods. Invasive diagnostic procedures also have a low negative predictive value (NPV) in such cases. The current study aims to establish a specific and clinically practical metabolic parameter for lipid-poor adrenal lesions (ALs) in NSCLC patients. This diagnostic approach may prevent unnecessary abdominal enhanced computed tomography (CT), magnetic resonance imaging, or invasive diagnostic procedures. Sixty-four NSCLC patie...

CONCLUSIONS: The workflows developed in this study are expected to enable researchers to create segmented images and optimized surface models from any set of serially sectioned images quickly and conveniently. Moreover, these optimized surface models can easily be modified for further application or educational use. PMID: 30993664 [PubMed - as supplied by publisher]

INTRODUCTION: Post Mortem Computed Tomography (PMCT) and 3D reconstruction provide a powerful tool in the evaluation of the causes of death, distinguishing between those findings related to traumas and those related to post mortal changes. It has proven to...

Authors: Kim E, Kim MS, Kim Y Abstract Post-traumatic striatocapsular infarction is extremely rare and has been described only within the vascular territory of the perforating arteries originating from the middle cerebral artery (MCA). We recently encountered a patient presenting with unilateral multifocal striatocapsular hemorrhagic infarctions following mild head injury. This 25-year-old female was admitted to our trauma center after a motorcycle accident. Initial brain computed tomography and magnetic resonance (MR) imaging showed multifocal acute hemorrhagic infarctions with a clustering in the right caudate he...

Sarcopenia is a predictor of mortality in elderly patients. Masseter area (MA) reflects sarcopenia in trauma patients. It was hypothesised that MA and Masseter density (MD) could be evaluated reliably from pre-operative computed tomography angiography (CTA) scans and that they predict post-operative survival in carotid endarterectomy (CEA) patients.

The article entitled “Anatomic eligibility for transcarotid artery revascularization and transfemoral carotid artery stenting” in this issue of the Journal of Vascular Surgery1 is an important study in that it represents the initial report of anatomic eligibility for transcarotid artery revascularization (TCAR) in a “real-world” practice cohort whose only unifying characteristic was the performance of a carotid intervention and the availability of a carotid computed tomography angiography (CTA) image for retrospective review.

Malware is being used to manipulate CT and MRI scans to create detrimental misdiagnoses, according to researchers from theBen-Gurion University Cyber Security Research Center inBeersheba,Israel. In lieu of the data breaches and cyber attacks that plagued hospitals in 2018, the researchers set out to learn how attackers use deep learning to implant fake cancerous nodules or remove real ones in medical scans without expert radiologists having the slightest idea. In a blind study, radiologists read a batch of real CT scans, 70 percent of which had been doctored by malware. For all of the scans with fake cancerous nodules, the...
