Introduction: The present study aimed to measure the scatter and leakage dose received by out-of-field organs while delivering Radiotherapy (RT) treatment of cervical cancer. Moreover, this study estimated the risk of second cancer (SC). The doses to out-of-field organs were measured using a lithium fluoride (TLD 100) dosimeter while delivering External Beam Radiothera...

Management of locally advanced colon cancer metastases is challenging and operation carries an increased risk of morbidity and mortality. The knowledge of exact sites of involvement can aid the surgeon to make a decision regarding complete resection or palliative therapy. PET/CT scan is an advantage in this setting because metabolic alterations often precede the anatomic changes; moreover, it c...

The Camera Augmented Mobile C-arm (CamC) system that extends a regular mobile C-arm by a video camera provides an X-ray and video image overlay. Thanks to the mirror construction and one time calibration of the device, the acquired X-ray images are co-registered with the video images without any calibration or registration during the intervention. It is very important to quantify and qualify th...

In the screening and identifying of colon rectum malignancy, computed tomography colonography (CTC) is a highly effective imaging technique, albeit patients receiving significant dose. Accordingly, patient dose evaluation an important need, seeking to ensure benefits outweigh projected cancer risk. Objective: For CTC procedures carried out in Radiology Department, Medical Imaging Operation Serv...

aim : the aim of this study was to report the anatomical location and histologic type of colorectal polyps in a large series of iranian patients that attended for colonoscopy. background : polyps that develop through the adenoma-carcinoma pathway are considered neoplastic and may eventually progress to invasive carcinomas. in addition polyps can develop with no neoplastic potential. these neopl...

introduction: ulcerative colitis is a chronic inflammation of the large intestine (colon). in patients with ulcerative colitis, ulcers and inflammation of the inner lining of the colon lead to symptoms such as abdominal pain, diarrhea, and rectal bleeding. previous studies have shown that matricaria recutita l. have a series of physiological effects for example spasmolytic, carminative, antioxi...

Background: Although ionizing radiation is widely used to diagnose many diseases, the relevant hazards are known to be as an important limitation of its application. It is believed that the awareness of ionizing radiation dose values is one of the main stages in patient's radiation protection. The purpose of this study has been to investigate the level of physicians' knowledge about radiation d...

Introduction: Computed tomography (CT) consists of 11% of all imaging methods, but accounts for approximately 67% of radiation exposure due to diagnostic cases. More than one-third of all CT scans are done in the head and neck area. The thyroid gland is irradiated during CT head and neck. According to studies, this gland has the highest levels of radiation-induced cancer, and i...

Background: The SALL4/Sall4 is constitutively expressed in human and mice. SALL4 mRNA could be used as a marker for the diagnosis of different types of cancers. On the other hand, chrysin has diverse biological properties. Objectives: In the present study, the effect of the chrysin was investigated on the CT26 colon cancer in vitro and in vivo. Furthermore, the expression levels of the stem cel...
