(P002) Differential Expression of Microrna Between Standard Conventional Dose Versus Ablative Dose Radiation in Colorectal Cancer

Standard dose versus low-dose abdominal and pelvic CT: comparison between filtered back projection versus adaptive iterative dose reduction 3D.

PURPOSE To compare the dose and image quality of a standard dose abdominal and pelvic CT with Filtered Back Projection (FBP) to low-dose CT with Adaptive Iterative Dose Reduction 3D (AIDR 3D). MATERIALS AND METHODS We retrospectively examined the images of 21 patients in the portal phase of an abdominal and pelvic CT scan before and after implementation of AIDR 3D iterative reconstruction. Th...

Patient Dose in Digital versus Conventional Mammography

Abstract. Breast imaging techniques have received renewed attention as a proved means for earlier detection and diagnosis of breast cancer. Due to the extremely high image quality requirements in mammography, all aspects of the imaging process must be optimised. With this purpose new imaging systems have been incorporated. The aim of this paper is to present results of patient dose comparison i...

MicroRNA expression profiles in human breast cancer cells after multifraction and single-dose radiation treatment.

MicroRNAs (miRNAs) are small non-coding RNAs that contribute to modulating signaling pathways after radiation exposure and have emerged as a potential therapeutic target or biomarker in the radiation response of cancer. Exposing breast cancer cells to single-dose (SD) or multifractionated (MF) radiation may affect the cells differently. However, the roles of miRNAs in breast cancer cells after ...

High-dose-rate intraoperative radiation therapy for colorectal cancer.

Intraoperative radiation therapy (IORT) has the obvious advantage of maximally irradiating the tumor bed while eliminating surrounding normal organs from the field of radiation. This approach has been especially useful when the required radiation dose exceeds the tolerance dose of the surrounding normal tissues. However, the application of IORT has been significantly limited by cost, logistic i...
