introduction: recently, magnetic resonance spectroscopic imaging (mrsi), as a functional imaging method, has been used for clinical target volume definition. in this study, we used this method to define the target volume in prostate radiotherapy. material and method: in this study, we used images of 20 prostate cancer cases. mrsi and mri images were fused with ct images. then, treatment plannin...

PURPOSE Head and neck radiotherapy planning with positron emission tomography/computed tomography (PET/CT) requires the images to be reliably registered with treatment planning CT. Acquiring PET/CT in treatment position is problematic, and in practice for some patients it may be beneficial to use diagnostic PET/CT for radiotherapy planning. Therefore, the aim of this study was first to quantify...

The aim of the study was to assess response preoperative radiotherapy (RT) in patients with G2-G3 rectal neuroendocrine tumors (NETs). Material and methods . Case reports involving who were given treatment at N.N. Blokhin National Medical Research Center Oncology from 2000 2020 retrospectively studied. Patients histologically verified rectum anal canal (G2 G3, Ki67>3%), underwent or chemorad...

ObjectiveImproved preoperative evaluation of lymph node status could potentially replace lymphadenectomy in women with endometrial cancer. PET/CT was routinely implemented the workup cancer at St Olav’s University Hospital 2016. Experience is limited, and there no consensus about use diagnostic The aim study to evaluate accuracy compared standard CT/MRI identifying metastases histologically con...

Background. Combined radiation therapy is the «gold standard» for treatment of stages IIB-IVA cervical cancer (cervical cancer). Given data statistical indicators cancer, study new approaches to and implementation in clinical practice modern technologies widespread an extremely important area.
 Purpose – evaluate benefits using CT topometric preparation planning brachytherapy cancer.

Background: In the radiotherapy of patients with esophagus and breast cancer, the heart receives a significant dose of radiation that might cause heart complications. Thefore, the aim of the current study was to evaluate the effects of esophagus and left breast cancer radiotherapy on the cardiac function and to determine the relationship between the dosimetric parameters and ejection fraction (...

Radiotherapy is the treatment of cancer by using electromagnetic and particle radiation. Nasopharyngeal Cancer (NPC) one difficult case to be treated in radiotherapy because its anatomical location. Precision radiation dose part Quality Assurance Program as key factor this treatment. Thus, it very important ensure that output Linear Accelerator (LINAC) matched with result Treatment Planning Sys...

The aim of this study was to evaluate the impact of integrated positron emission tomography (PET)/computed tomography (CT) imaging on staging and radiotherapy treatment volume definition of non-small cell lung cancer (NSCLC). Thirty-nine patients with NSCLC referred to the Department of Radiation Oncology of Gulhane Military Medical Academy, for radical radiotherapy between June 2011 and Decemb...

Radioimmunoscintigraphy (RIS) using human monoclonal antibodies offers the important clinical advantage of repeated imaging over murine monoclonal antibodies by eliminating the cross-species antibody response. This article reports a Phase I-II clinical trial with Tc-99m-labeled, totally human monoclonal antibody 88BV59H21-2 in patients with colorectal carcinoma. The study population consisted o...
