Prostate contouring in MRI guided biopsy.
With MRI possibly becoming a modality of choice for detection and staging of prostate cancer, fast and accurate outlining of the prostate is required in the volume of clinical interest. We present a semi-automatic algorithm that uses a priori knowledge of prostate shape to arrive at the final prostate contour. The contour of one slice is then used as initial estimate in the neighboring slices. ...
متن کاملCASE REPORT: Combined Er:YAG and Nd:YAG Laser Treatment for Non-invasive Body Contouring
Although laser lipolysis has been described as a “lunchtime treatment”, it is nevertheless classified as a surgical procedure associated with certain risks due to surgical incisions and the use of anesthetics, as well as with subsequently reduced skin firmness and lack of skin ability to conform to the reduced body size. We aimed to develop a safe and effective alternative to address both exces...
متن کاملInter-observer variability in contouring the penile bulb on CT images for prostate cancer treatment planning
Several investigations have recently suggested the existence of a correlation between the dose received by the penile bulb (PB) and the risk of erectile dysfunction (ED) after radical radiotherapy for clinically localized prostate carcinoma. A prospective multi-Institute study (DUE-01) was implemented with the aim to assess the predictive parameters of ED. Previously, an evaluation of inter-obs...
متن کاملCT slice index and thickness: Impact on organ contouring in radiation treatment planning for prostate cancer
OBJECTIVE To assess the impact of CT slice index and thickness (3 mm versus 5 mm) on (i) prostate volume, dimensions, and isocenter coordinates, (ii) bladder and rectal volumes, and (iii) DRR quality, in the treatment of prostate cancer. METHODS 16 patients with prostate cancer underwent two planning CT-scans using 3 and 5 mm slice index/thickness. Prostate, bladder, and rectum were outlined ...
متن کاملAuto-contouring the Prostate for Online Adaptive Radiotherapy
Among all the organs under cancer treatment, prostate is a very important one in male pelvic region but very difficult to segment, due to the poor contrast of 3D CT images, invisible boundaries between the prostate and its neighboring organs (e.g. bladder, rectum), and artifacts produced by prostate seeds etc. Furthermore, the same patient’s organ conditions (e.g. size, shape and location) can ...
