Amebic Infection of the Female Genital Tract: A Report of Three Cases.

Amebiasis is a common protozoan disease with a worldwide distribution. It is endemic in tropical developing countries, and cases are being detected in subtropical countries as well. It usually presents with intestinal manifestations.

A phantom study on the behavior of Acuros XB algorithm in flattening filter free photon beams.

To study the behavior of Acuros XB algorithm for flattening filter free (FFF) photon beams in comparison with the anisotropic analytical algorithm (AAA) when applied to homogeneous and heterogeneous phantoms in conventional and RapidArc techniques. Acuros XB (Eclipse version 10.0, Varian Medical Systems, CA, USA) and AAA algorithms were used to calculate dose distributions for both 6X FFF and 10X FFF energies.

Small field dosimetry and analysis of flattening filter free beams in true beam system.

Aim Of Study: The purpose of this study was to report the dosimetric characteristics of the small fields in flattening filter free (FFF) beams (output measurements, profile analysis, surface dose and consistency) generated by medical linear accelerator and its variation with respect to flattened beams (FB).

Materials And Methods: Surface doses were obtained for field sizes 1 × 1-40 × 40 cm(2). Field width and penumbra were analyzed for field sizes 1 × 1-40 × 40 cm(2).

"Metabolic signature" of the lesions on F18-fluoro-deoxyglucose positron emission tomography: A clue to the underlying pathology.

Increase in glycolytic pathway, forms one of the major adaptations in various cancer types. This can be imaged using (18)F-fluoro-deoxyglucose positron emission tomography/computed tomography (FDG PET). The intensity of FDG avidity is an indirect marker of the grade of the tumor.

18F-Fluoride bone positron emission tomography demonstrating changes related to finger clubbing and hypertrophic osteoarthropathy.

Hypertrophic pulmonary osteoarthropathy is manifested by clubbing and periostitis of bones. We present a very rare documentation of increased F18-sodium fluoride uptake in the distal phalanges of both hands correlating to clubbing of the fingers in a 55-year-old female patient with carcinoma of lung in whom bone positron emission tomography was performed for metastatic work-up.
