Article Synopsis
- The study analyzed the agreement of TI-RADS scores between sonographers and radiologists in assessing suspicious thyroid nodules and evaluated the diagnostic accuracy of these scores against histological results.
- Results showed moderate agreement overall (κ = 0.504) but poor agreement for nodule margins (κ = 0.102). Both groups had high sensitivity (100%), but sonographers had better specificity (44.6%) compared to radiologists (29.3%).
- The findings suggest potential benefits of involving sonographers in initial assessments, while future research should focus on reducing scoring variability and exploring a broader range of TI-RADS categories for better clinical application.
Background: Temporomandibular disorders (TMDs) pose diagnostic challenges, and selecting appropriate imaging modalities is crucial for accurate assessment. This study aimed to compare the diagnostic accuracy and efficacy of ultrasonography (US) and magnetic resonance imaging (MRI) in identifying TMDs.
Methods: A comprehensive meta-analysis was conducted, including studies that compared US and MRI for TMJ disorder assessments.
Article Synopsis
- Posterior cerebral ischemic strokes are frequently misdiagnosed, with over a third of cases potentially going unnoticed during routine CT scan evaluations unless examined by expert radiologists.
- A study was conducted involving 30 radiologists (15 senior residents and 15 general radiologists) in Riyadh to evaluate their agreement with a specialized neuroradiologist on identifying posterior circulation calcification (PCC) in brain CT scans.
- Results showed a high misdiagnosis rate (> 93%) among SRRs and GRs for PCC cases, indicating poor inter-observer agreement, especially in distinguishing severe and mild forms of PCC.
Backgroun: Full-thickness rotator cuff tear is common in the older population. The incidence of traumatic deltoid tears post-surgery is well addressed. However, non-traumatic spontaneous injury is not well recognized despite a few case reports and previous studies.

Material And Methods: An analytical cross-sectional prospective study was conducted. A total of 49 patients with AVF hemodialysis access were recruited.
Purpose: Magnetic resonance imaging (MRI) is an important diagnostic method in modern clinical medicine. Patients' knowledge about MRI is of utmost importance for optimizing the workflow, safety, and patient comfort and saving valuable time for the MRI department. This study investigates patient knowledge levels regarding MRI safety before an MRI examination.

Methods: This retrospective study was carried out on 4,435 chest CT examinations that were collected between January 2014 and December 2016 in Riyadh, Saudi Arabia. One musculoskeletal radiologist who was unaware of the patients' clinical presentations or reasons for CT study reviewed the 4,435 chest CTs prospectively, searching for soft tissue tumors in the subscapular region.
Purpose: To examine the various facets of job satisfaction among radiographers in Saudi Arabia and compare the influential contributing factors locally and internationally.
Methods: A cross-sectional survey was conducted in June and July 2020 with an electronic questionnaire distributed to radiographers in Saudi Arabia. The validated Job Satisfaction Survey was used to measure overall job satisfaction and specific satisfaction regarding pay, promotions, supervision, benefits, contingent rewards, operating conditions, coworkers, nature of work, and communication (total Job Satisfaction Survey score can range from 36 to 216).
Background: Ultraportable or pocket handheld ultrasound devices (HUD) may be useful for large-scale abdominal aortic aneurysm screening. However, the reproducibility of measurements has not been compared with conventional cart-based ultrasound machines.
Objectives: Investigate the intra- and inter-operator reproducibility of a HUD compared with a conventional ultrasound machine for aortic screening.
Objectives: To assess the usefulness of sonographically measured anogenital distance (AGD) in predicting fetal gender in Saudi fetuses during the first trimester and to provide normal reference centiles for AGD.
Methods: A retrospective cohort study was conducted at King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia between November 2020 and May 2021. The ultrasound scans of 313 singleton pregnancies between 11-13 plus 6 gestational weeks and their gender-at-birth were collected.
