Clinical Features and Survival Outcomes of Invasive Aspergillosis in Pediatric Patients at a Medical School in Thailand.
CONCLUSION: The 1-year survival rate was poor; however, cause of death is related to complications of the immunocompromised state not from IA. PMID: 27249894 [PubMed - in process]

Four Challenges in Medical Image Analysis from an Industrial Perspective
Over the last 20 years, medical imaging systems have evolved considerably. Advances in acquisition technology such as multi-slice Computed Tomography (CT), digital Photon Emission Tomography (PET), parallel Magnetic Resonance Imaging (MRI) or Ultrasound (US) transducer technology have not only enabled the acquisition of much better images with higher resolution, they enabled also the generation of many more images. In addition, the diversity of imaging protocols in usage has increased. 2D imaging techniques such as 2D US and 2D X-ray remain important and are complemented by (rather than replaced by) 3D techniques.

Development of a universal medical X-ray imaging phantom prototype
Diagnostic X-ray imaging depends on the maintenance of image quality that allows for proper diagnosis of medical conditions. Maintenance of image quality requires quality assurance programs on the various X-ray modalities, which consist of pro ­jection radiography (including mobile X-ray units), fluoroscopy, mammography, and computed tomography (CT) scanning. Currently a variety of modality-specific phantoms are used to perform quality assurance (QA) tests. These phantoms are not only expensive, but suitably trained personnel are needed to successfully use them and interpret the results. The question arose as to whether a...

3D Deeply Supervised Network for Automated Segmentation of Volumetric Medical Images
Delineating important organs or structures from volumetric medical images, such as 3D computed tomography (CT) and magnetic resonance (MR) images, is of great significance for clinical practice especially with the proliferation of 3D images in diagnosis and treatment of many diseases. Accurate segmentation not only facilitates the subsequent quantitative assessment of the regions of interest but also benefits precise diagnosis, prediction of prognosis, and surgical planning and intra-operative guidance.

Abstract ID: 194 Validation of GPUMCD for X-ray medical imaging
GPUMCD, a fast GPU-based Monte Carlo transport code, was initially developed and validated for photon and electron dose calculations in radiation oncology. In this work, the code was adapted to X-ray medical imaging applications, notably to simulate Cone-Beam Computed Tomography (CBCT) projections.The photon interaction processes in GPUMCD, initially validated for the therapeutic (megavoltage) energy range, were revisited with imaging and therefore lower energies in mind. Comparisons with physics models available in Geant4 were conducted for the photoelectric effect, Compton and Rayleigh scattering.

Medical Care Costs Were Similar Across the Low-dose Computed Tomography and Chest X-Ray Arms of the National Lung Screening Trial Despite Different Rates of Significant Incidental Findings
Background: The National Lung Screening Trial (NLST) reported lung cancer and all-cause mortality reductions for low-dose computed tomography (LDCT) versus chest x-ray (CXR) screening. Although LDCT lung screening has received a grade B from the United States Preventive Services Task Force and is a covered service under most health plans, concerns remain on the costs engendered by screening, and the impact of the high rate of significant incidental finding (SIF) detection on those costs. Methods: We linked American College of Radiology Imaging Network NLST and Medicare fee-for-service claims data for participants from...

Medical Image Synthesis with Context-Aware Generative Adversarial Networks.
Authors: Nie D, Trullo R, Lian J, Petitjean C, Ruan S, Wang Q, Shen D Abstract Computed tomography (CT) is critical for various clinical applications, e.g., radiation treatment planning and also PET attenuation correction in MRI/PET scanner. However, CT exposes radiation during acquisition, which may cause side effects to patients. Compared to CT, magnetic resonance imaging (MRI) is much safer and does not involve radiations. Therefore, recently researchers are greatly motivated to estimate CT image from its corresponding MR image of the same subject for the case of radiation planning. In this paper, we propose a d...

Characterizing mechanical and medical imaging properties of polyvinyl chloride-based tissue-mimicking materials.
Abstract Polyvinyl chloride (PVC) is a commonly used tissue-mimicking material (TMM) for phantom construction using 3D printing technology. PVC-based TMMs consist of a mixture of PVC powder and dioctyl terephthalate as a softener. In order to allow the clinical use of a PVC-based phantom use across CT and magnetic resonance imaging (MRI) imaging platforms, we evaluated the mechanical and physical imaging characteristics of ten PVC samples. The samples were made with different PVC-softener ratios to optimize phantom bioequivalence with physiologic human tissue. Phantom imaging characteristics, including computed to...

Diagnostic yield of computed tomography ‐guided biopsy and aspiration for vertebral osteomyelitis
ConclusionsPercutaneous CT ‐guided biopsy has a modest yield for identifying the culprit organism in suspected cases of vertebral osteomyelitis. Elevated CRP and aspiration of fluid collections are associated with improved microbiological yield and should be considered in deciding when and where to biopsy.

Is medical urgency of elderly patients with traumatic brain injury underestimated by emergency department triage?
Conclusion: Elderly patients with isolated TBI are managed differently than younger patients, which could be due to an under-triage of elderly patients by RETTS-A. PMID: 31986958 [PubMed - as supplied by publisher]
