“…CT 4 -often referred to as CAT scans for computed axial tomography-was invented in 1972 by Hounsfield and Cormack 20 and was adopted widely soon thereafter. CT acquires slices or cross-sectional images through the body to provide a much more detailed view of the anatomy than can be captured by plain film.…”

Introduction: Radiology was founded on a technological discovery by Wilhelm Roentgen in 1895. Teleradiology also had its roots in technology dating back to 1947 with the successful transmission of radiographic images through telephone lines. Diagnostic radiology has become the eye of medicine in terms of diagnosing and treating injury and disease. This article documents the empirical foundations of teleradiology. Methods: A selective review of the credible literature during the past decade (2005-2015) was conducted, using robust research design and adequate sample size as criteria for inclusion. Findings: The evidence regarding feasibility of teleradiology and related information technology applications has been well documented for several decades. The majority of studies focused on intermediate outcomes, as indicated by comparability between teleradiology and conventional radiology. A consistent trend of concordance between the two modalities was observed in terms of diagnostic accuracy and reliability. Additional benefits include reductions in patient transfer, rehospitalization, and length of stay.

The radiological community is endeavouring to raise the awareness about the radiation-induced cancer. Computed Tomography (CT) is the main source of medical irradiation. Manufacturers provided efficient technological tools on CT to achieve a significant radiation dose reduction while maintaining a diagnostic quality of the image. Yet, the implementation of all these improvements allowing the low-dose (LD) and ultra-low-dose (ULD) CT imaging has difficulty to take hold. Radiologists do not easily accept to read images with a degraded image quality although diagnostic. As every cultural change, even in a radiological department the acceptation of the LD/ULD-CT imaging requests time. Constant meetings with substantial exempla and constructive discussions among radiologists, without abrupt modifications to the CT protocols in clinical practice, are the key to the success.

“…Computed tomography (CT) is a 3-D medical imaging tool, with extensive beneficial impact on the diagnosis, characterization and explanation of complex health issues 1 . The latest development in spiral CT with electrocardiogram gating technology is with multislice CT (MSCT) which has allowed for the acquisition of large volumes data and for the obtainment of dynamic volume imaging 2,3 .…”

The multi-slice computerized tomography (MSCT) is a medical Background: imaging modality that has been used to determine the size and location of the stomach cancer. Additionally, MSCT is considered the best modality for the staging of gastric cancer. One way to assess the type 2 cancer of stomach is by detecting the pathological structure with an image segmentation approach. The tumor segmentation of MSCT gastric cancer images enables the diagnosis of the disease condition, for a given patient, without using an invasive method as surgical intervention.This approach consists of three stages. The initial stage, an image Methods: enhancement, consists of a method for correcting non homogeneities present in the background of MSCT images. Then, a segmentation stage using a clustering method allows to obtain the adenocarcinoma morphology. In the third stage, the pathology region is reconstructed and then visualized with a three-dimensional (3-D) computer graphics procedure based on marching cubes algorithm. In order to validate the segmentations, the Dice score is used as a metric function useful for comparing the segmentations obtained using the proposed method with respect to ground truth volumes traced by a clinician.A total of 8 datasets available for patients diagnosed, from the cancer Results: data collection of the project, Cancer Genome Atlas Stomach Adenocarcinoma (TCGASTAD) is considered in this research. The volume of the type 2 stomach tumor is estimated from the 3-D shape computationally segmented from the each dataset. These 3-D shapes are computationally reconstructed and then used to assess the morphopathology macroscopic features of this cancer.The segmentations obtained are useful for assessing Conclusions:qualitatively and quantitatively the stomach type 2 cancer. In addition, this type
