The Role of MRSI in Target Volume Definition for Radiation Therapy of Prostate Cancer
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...

متن کامل18F-fluorocholine PET-guided target volume delineation techniques for partial prostate re-irradiation in local recurrent prostate cancer.
BACKGROUND AND PURPOSE We evaluate the contribution of (18)F-choline PET/CT in the delineation of gross tumour volume (GTV) in local recurrent prostate cancer after initial irradiation using various PET image segmentation techniques. MATERIALS AND METHODS Seventeen patients with local-only recurrent prostate cancer (median=5.7 years) after initial irradiation were included in the study. Rebio...
متن کاملPostoperative Radiation Therapy for Prostate Cancer
Prostate cancer is a common problem for US men. Once patients are initially diagnosed, they are often treated with either surgery or radiation therapy. For those whose initial treatment is radical prostatectomy, recurrences of cancer can be detected at an early stage by monitoring the blood levels of prostatic specific antigen (PSA). Once the PSA level becomes detectable, radiation therapy deli...
متن کاملSalvage Therapy for Prostate Cancer
Biochemical recurrence after treatment of prostate cancer occurs in 30–50 % of patients. Confirming that recurrence is localized to the pelvis is challenging as PSA is nonspecific and imaging modalities are imperfect in identifying location of recurrent disease. Salvage therapy after radical prostatectomy is limited to external beam radiotherapy and androgen-deprivation therapy. After radiothe...
