Prospective Feasibility Study of Laparoscopic and Robotic Distal Gastrectomy for Advanced Gastric Cancer to Verify the Safety of Surgical Proximal Margins

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Ensuring an adequate surgical proximal margin (SPM) is crucial in radical gastrectomy for gastric cancer. However, the lack of tactile feedback in laparoscopic distal gastrectomy (LDG) and robotic distal gastrectomy (RDG) poses challenges in precisely determining tumor boundaries, particularly in advanced gastric cancer, where tumor ...

Tumor-site specific geometric distortions in high field integrated magnetic resonance linear accelerator radiotherapy

Physics and Imaging in Radiation Oncology, 2020
Magnetic resonance imaging (MRI) has exquisite soft-tissue contrast and is the foundation for image guided radiotherapy (IGRT) with integrated magnetic resonance linacs. However, MRI suffers from geometrical distortions. In this study the MRI system- and

Silicosis, Sarcoidosis, and Silicosarcoidosis Are Overlapping Diagnoses and Difficult to Differentiate

American Journal of Industrial Medicine, EarlyView.
ABSTRACT We evaluated 12 workers with documented exposure to respirable crystalline silica who were referred to a tertiary care center due to clinical suspicion of silicosis, sarcoidosis, or silicosarcoidosis. Although silica exposure is a well‐established risk factor for silicosis and has been associated with autoimmune diseases, mycobacterial ...

[I186] New technologies for MR guided radiotherapy

Physica Medica, 2018
Purpose Provide an overview of technological developments in MR guided Radiotherapy. The key concept in MR guided Radiotherapy (MRgRT) is that the soft tissue contrast allows direct visualization of the tumor and organs-at-risk [1] . In this way an optimal plan can be devised for the actual position, shape and motion characteristics of a patient for

Use of radiobiological modeling in treatment plan evaluation and optimization of prostate cancer radiotherapy [PDF]

, 2011
There are many tools available that are used to evaluate a radiotherapy treatment plan, such as isodose distribution charts, dose volume histograms (DVH), maximum, minimum and mean doses of the dose distributions as well as DVH point dose constraints ...

Characterization of spatial integrity with active and passive implants in a low-field magnetic resonance linear accelerator scanner

Physics and Imaging in Radiation Oncology
Background and Purpose: Standard imaging protocols can guarantee the spatial integrity of magnetic resonance (MR) images utilized in radiotherapy. However, the presence of metallic implants can significantly compromise this integrity. Our proposed method
