BACKGROUND The respiratory related target motion and setup error will lead to a large margin in the gastric radiotherapy. The purpose of this study is to investigate the dosimetric benefit and the possibility of incorporating the breath-hold (BH) technique with online image-guided radiotherapy in the adjuvant gastric cancer radiotherapy. METHODS Setup errors and target motions of 22 post-oper...
Prevention is essential for avoiding the complications of muscle hematomas (pseudotumors, compartment syndromesand peripheral nerve lesions) in hemophilic patients. This is achieved through early diagnosis of muscle hematomasand proper long-term hematological treatment until they have resolved (confirmed by image studies). Ultrasound-guidedpercutaneous drainage could be benefi...
Introduction: Radical prostatectomy is an effective curative treatment option for organ-confined prostate cancer. There is a recent trend in offering curative treatment to patients with oligometastatic disease. More sensitive imaging modalities can identify oligometastatic disease that is not usually detected by conventional imaging techniques. Case presentation: We present a case in which a s...

Abstract Nasopharyngeal cancer shows a good response to intensity-modulated radiotherapy. However, there is no clear evidence for the benefits of routine use image-guided The purpose this study was perform retrospective investigation treatment outcomes, treatment-related complications and prognostic factors nasopharyngeal treated with radiotherapy techniques. Retrospective analysis performed on...
Patients with left-sided breast cancer are at risk of cardiac toxicity because of cardiac irradiation during radiotherapy with the conventional 3-dimensional conformal radiotherapy technique. In addition, many patients may receive chemotherapy prior to radiation, which may damage the myocardium and may increase the potential for late cardiac complications. New radiotherapy techniques such as in...
BACKGROUND Preclinical radiation biology has become increasingly sophisticated due to the implementation of advanced small animal image guided radiation platforms into laboratory investigation. These small animal radiotherapy devices enable state-of-the-art image guided therapy (IGRT) research to be performed by combining high-resolution cone beam computed tomography (CBCT) imaging with an isoc...
Patients with early stage high-risk prostate cancer (prostate specific antigen > 20, Gleason score > 7) are at high risk of recurrence following prostate cancer irradiation. Radiation dose escalation to the prostate may improve biochemical-free survival for these patients. However, high rectal and bladder dose with conventional three-dimensional conformal radiotherapy may lead to excessive gast...
