The role of effective dose in medicine now and into the future.

Effective dose was created as a radiological protection dose quantity linked to risk to enable planning of radiological protection for the control of exposure. Its application and use has evolved from occupational and public exposure during work with radiation sources to medicine and applications in patient dosimetry. Effective dose is the sum of doses to organs and tissues within the body weighted according to their sensitivity to radiation for induction of stochastic effects determined from epidemiological studies of exposed populations.

Intraosseous mandibular schwannoma managed via submandibular approach: a case report with a review of previously published cases.

A 40-year-old female presented with right mandibular swelling. A panoramic radiograph showed a unilocular radiolucency from the mandibular angle to tooth #46. Biopsy confirmed a schwannoma.

The adherence to asthma medication for hospitalized children with asthma: A cross-sectional study in a tertiary hospital in Riyadh, Saudi Arabia.

Aim: The aim of the study was to assess adherence to asthma controller therapy and factors that influence asthma control and to determine the association between asthma knowledge of the caregiver and asthma control among admitted children with asthma.

Settings And Design: A cross-sectional study was conducted between November 2022 and May 2023 in a tertiary care hospital. Children with a diagnosis of asthma aged 2-14 years, who were admitted to the hospital with an exacerbation of asthma were identified.

Estimation of organ and effective doses of CBCT scans of radiotherapy using size-specific field of view (FOV): a Monte Carlo study.

The kV cone beam computed tomography (CBCT) is one of the most common imaging modalities used for image-guided radiation therapy (IGRT) procedures. Additional doses are delivered to patients, thus assessment and optimization of the imaging doses should be taken into consideration. This study aimed to investigate the influence of using fixed and patient-specific FOVs on the patient dose.

Estimation of size-specific dose estimate (SSDE) of CT scans using an effective diameter electron density.

Objective: An assessment of the effective diameter of a patient's body using electron densities of tissues inside the scan area (D) was proposed to overcome challenges associated with the estimation of water-equivalent diameter (D), which is used for size-specific dose estimate (SSDE). The aims of this study were to (1) investigate the D method in two different forms using a wide range of patient sizes and scanning protocols, and (2) compare between four methods used to estimate the patient size for SSDE.

Materials And Methods: Under IRB approval, a total of 350 patients of varying sizes have been collected retrospectively from the Hospital.
