PURPOSE To report clinical and treatment characteristics, remission failure patterns, risk factors for local (LF) from the EMBRACE-I study. MATERIALS AND METHODS was a prospective, observational, multicenter cohort study on magnetic resonance imaging–based image-guided adaptive brachytherapy (MR-IGABT) in locally advanced cervical cancer. Treatment consisted of external beam radiotherapy, concurrent chemotherapy, MR-IGABT. LF defined as progressive or recurrent disease cervix, uterus,...
Purpose/ObjectivesTo compare health-related Quality of Life (QoL) in urinary, bowel and sexual domains after combined external beam radiotherapy (EBRT) either low dose rate (LDR) or high (HDR) prostate brachytherapy (BT).Materials/MethodsEligible men with intermediate high-risk cancer, treated pelvic EBRT BT were randomly assigned to HDR (15 Gy) LDR (110 boost. International Prostate Symptom Score (IPSS), Index Erectile Function (IIEF), Expanded Cancer Composite (EPIC-26) collected at...
Quantitative analysis of bone composition is necessary for the accurate diagnosis and monitoring metabolic diseases. Accurate assessment mineralization state first requirement a comprehensive analysis. In diagnostic imaging, x‐ray coherent scatter depends upon molecular structure tissues. Coherent‐scatter computed tomography (CSCT) exploits this feature to identify tissue types in composite biological specimens. We have used CSCT map distributions tissues relevant disease (fat, soft tissue,...
High-dose-rate brachytherapy of the prostate is commonly performed using transrectal ultrasound (US) guidance, with CT imaging used for needle reconstruction and treatment planning. Transrectal images can, however, be entire process, allowing without changes in patient position. This study assesses accuracy US images.Prostate phantoms were implanted 10-18 needles. Three-dimensional acquired, needles reconstructed specialized software. A scan was also obtained. The image sets registered...
Postplan evaluation is essential for quality assurance in prostate brachytherapy. MRI has demonstrated greater interobserver consistency contouring compared with CT. Although a valuable tool postimplant assessment, costly and not always available. Our purpose to compare dosimetry obtained using fusion of CT preimplant transrectal ultrasound (TRUS) vs. CT-MR fusion.
Coherent‐scatter computed tomography (CSCT) is a novel imaging method we are developing to produce cross‐sectional images based on the low‐angle (<10°) scatter properties of tissue. At diagnostic energies, this primarily coherent with dependent upon molecular structure scatterer. This facilitates production material‐specific maps each component in conglomerate. Our particular goal obtain quantitative bone‐mineral content. A x‐ray source and image intensifier used acquire patterns under...
Knowledge of urinary stone composition and structure provides important insights in guiding treatment preventing recurrence. No current method can successfully provide information relating intact stones. We are developing a tomographic technique that uses measures coherently scattered diagnostic x-rays to yield composition. Coherent-scatter (CS) properties depend on molecular are, therefore, sensitive material Powdered, amorphous or polycrystalline materials with no significant orientation...
