Evaluation of Radiation Dose Reduction and its Effect on Image Quality for Different Flat-Panel Detectors.

Purpose: To evaluate the image quality of semi-anatomical chest radiographs acquired using low radiation doses from seven different flat-panel detector (FPD) systems.

Materials And Methods: Radiographs of a semi-anatomical chest phantom were acquired at 70 and 110 kVp using 7 different FPDs from 5 vendors. Radiation doses were measured using a dose-area-product (DAP) meter.

Cerebral Venous Thrombosis, Seasonal Trends, and Climatic Influence: A Region-SpecificStudy.

Background And Purpose: Studies looking at seasonal variation on cerebral venous thrombosis (CVT) are few with conflicting conclusions. In this region-specific study, we looked for climatic influence and seasonal trends on the incidence of CVT.

Methods: Imaging proven adult CVT cases treated over a period of 18 years from a specific geographical location with similar seasons and climatic conditions were studied.

Multiple Stab Incisions and Evacuation Technique for Contrast Extravasation of the Hand and Forearm.

Extravasation of intravenous contrast agents in the hand and forearm during computed tomography scanning is rising with the use of automated pressure injectors. The main concern in such a situation is progression to acute compartment syndrome and necrosis of the overlying skin. Management has been mainly nonsurgical comprising upper limb elevation and orthosis, with surgical techniques such as liposuction and saline evacuation mainly used for large volume (>50 mL) extravasations.
