Objective: To develop and validate an individualized nomogram for predicting adnexal torsion in women with abdominal pain and an adnexal mass based on preoperative non-contrast computed tomography (CT) findings.
Methods: This retrospective study included 200 women with surgically resected ovarian lesions who underwent preoperative non-contrast CT for abdominal pain from January 2017 to September 2023 in seven hospitals. The 200 patients were randomly divided into a development group (140 cases) and a validation group (60 cases).

Background Thyroid nodules are typically an initial sign of thyroid cancer (TC) and require evaluation by thyroid ultrasonography. Additional measures, such as fine needle aspiration, may be necessary depending on the level of malignancy risk. This study aims to comprehensively analyze TC clinical, radiological, and histopathological characteristics in a cohort of Saudi patients.

Purpose: Introducing compensated variable-prephasing (CVP), a phantom-based method for gradient waveform measurements. The technique is based on the variable-prephasing (VP) method, but takes into account the effects of all gradients involved in the measurement.
Methods: We conducted measurements of a trapezoidal test gradient and of an EPI readout gradient train with three approaches: VP, CVP, and fully compensated variable-prephasing (FCVP).

Background And Purpose: Timely reporting of CTA exams impacts management of acute vascular pathology such as large vessel occlusions, arterial dissection, and ruptured aneurysm as well as a variety of acute non-vascular pathologies. In this study, we examine potential modifiable factors impacting the timeliness of CTA reporting performed in stroke code activations.
Materials And Methods: Observational study of stroke code CTA head and neck exams performed at a single health system (3 emergency departments, 1550 inpatient beds) over four years (1/1/2019-12/31/2023).
