Abstract:
Background: Routine pelvic radiograph examination commonly performed in diagnostic radiology services is a pelvic examination of anteroposterior projection (AP). This results in direct exposure to ionizing radiation to the internal organs in the lower abdomen, especially the reproductive organs. Purpose: Optimizing the dosage of AP projection pelvic radiographs. Method: Research is conducted quantitatively and used experimental approach with an analysis of 15% mAs reduction from the standard mAs value on AP projection pelvic examination on radiation dose and image quality using anthropomorphic

Abstract:
Background: Abdominal radiography examination is one of the examinations that is routinely carried out on the abdominal area to diagnose abnormalities in the abdominal area using radiation. In the stomach area there are gonads which are organs that are sensitive to radiation. The X-rays that come out of the X-ray tube are polyenergy, that is, they are composed of low energy x-ray, medium energy x-ray and high energy x-rays. Low energy x-rays have no benefit on the radiographic image information produced, but only increase the radiation dose on the skin surface. The additional x-ray filter is a

Introduction. Pickwickian syndrome (PS), also known as hypoventilation syndrome in adults, consists of three factors: obesity [Body Mass Index (BMI) > 30 kg/m2], daytime hypercapnia and sleep-disordered breathing, after ruling out other disorders that may cause alveolar hypoventilation. Timely recognition of PS is of utmost importance because such patients have significant morbidity and mortality. However, recent data indicate that PS is under-recognized and under-treated. We report a case of early-identified PS prehospitally with a favorable outcome after hospital treatment. Case outline.

This study aimed to calculate and compare the estimated organ absorption dose, risk of cancer due to exposure, and dose received by the gonads for women and men in radio diagnostic examinations with different projections. Radiographic examination of the abdomen (with anterior-posterior (AP) and posterior-anterior (PA) projections) and lumbar vertebrae (with anterior-posterior projection (AP), Right posterior-anterior oblique (RPO), and Left posterior-anterior oblique (LPO)), were performed.

Background: Traditionally, radiologists have routinely recommended oral contrast agents (such as Telebrix®) for patients undergoing a computed tomography of the abdomen/pelvis (CTAP), but recent evidence has shown limited diagnostic benefits for most emergency department (ED) patients. Additionally, the use of oral contrast has numerous drawbacks, including patient nausea/vomiting, risk of aspiration and delays to CTAP completion and increased ED length of stay (LOS).

Several regulatory bodies have agreed that low-dose radiation used in medical imaging is a weak carcinogen that follows a linear, non-threshold model of cancer risk. While avoiding radiation is the best course of action to mitigate risk, computed tomography (CT) scans are often critical for diagnosis. In addition to the as low as reasonably achievable principle, a more concrete method of dose reduction for common CT imaging exams is the use of a diagnostic reference level (DRL).
