We present the first case of salvage radiotherapy based on the results of 18F-FACBC PET/CT performed for a PSA relapse after radical prostatectomy. The patients underwent 11CCholine PET/CT and multiparametric MRI that were negative while 18F-FACBC PET/CT visualized a suspected local relapse confirmed by transrectal ultrasound-guided biopsy. No distant relapse was detected. Thus the patient was ...

This document describes best practice and evidence based recommendations for the use of FDG-PET/CT for the purposes of radiotherapy target volume delineation (TVD) for curative intent treatment of nonsmall cell lung cancer (NSCLC). These recommendations have been written by an expert advisory group, convened by the International Atomic Energy Agency (IAEA) to facilitate a Coordinated Research P...

Cancer is a highly lethal disease that mainly treated by image-guided radiotherapy. Because the low dose of cone beam CT less harmful to patients, images are often used for target delineation in radiotherapy various cancers, especially breast and lung cancer. However, breathing heartbeat can cause position errors taken during different periods, also results insufficient imaging clarity, renderi...

  ABSTRACT   Background: While the benefits of Computed Tomography (CT) are well known in accurate diagnosis, those benefits are not risk free. CT is a device with higher patient dose in comparison with other conventional radiological procedures. Is the reduction of exposures by requiring optimization of CT procedures [a principle concern in radiological protection]? In this study, the radiatio...

background: to reduce uncertainties of patient positioning, the computerized tomography (ct) images acquired at the treatment planning time can be compared with those images obtained during radiation dose delivery. this can be followed during dose delivery procedure as image guided radiotherapy (igrt) to verify the prescribed radiation dose delivery to the target as well as to monitor radiation...

Many studies have pointed out the role of (18)F-FDG PET/CT (or (18)F-FDG PET) in patients with clinical stage III or II breast cancer. (18)F-FDG PET/CT might advantageously replace other staging procedures, such as bone scanning and possibly contrast-enhanced CT of the thorax or abdomen-pelvis. We discuss the findings, locoregional or distant, that can be expected in different categories of bre...

Extrapulmonary primary small cell carcinomas arising from the urogenital tract is infrequent. It can rarely arise from the prostate and even more rarely from the seminal vesicles. We present a 79-year-old male who was admitted due to acute renal failure with a history of radical radiotherapy for prostate adenocarcinoma 13 years ago. The prostate specific antigen level was not elevated. An abdom...

Case presentation 83 yr old lady presented with pain in left thigh and lower leg. There was history of lethargy, feeling tired and cold chills. Inflammatory markers were high with ESR 127 and CRP 203. Patient had history of malignant melanoma (2008) and AF on Warfarin. Examination of the hip showed reduced internal rotation. Xray pelvis, femur and chest were normal. USG abdomen showed heterogen...

Plans of patients with prostate tumor have been studied. These patients have been scanned in the CT simulator and the images have been sent to the Focal, the system where the doctor delineates the tumor and the organs at risk. After that in the treatment planning system XiO there are created for the same patients three dimensional conformal and intensity modulated radiotherapy treatment plans. ...

We report a case of a 75-year old man that came at hematologist’s attention for lymphoma evaluation due to axillary lymph node enlargement and fever. Thorax, abdomen and pelvis Contrast-Enhanced Computed Tomography (CECT) showed lymph nodes, spleen and liver lesions. Axillary lymph node biopsy was performed and the diagnosis of marginal zone lymphoma (MZL) at stage IV was postulated, then the p...
