AI Article Synopsis
- Recent reports highlight the value of abdominal computed tomography (CT) in diagnosing drug overdoses (OD), analyzing literature from 1983 to 2019.
- Out of 48 cases studied, 93.8% showed residual drugs on CT, with high-density fluid levels in the stomach being the most common finding.
- CT can assist in diagnosing OD, especially in comatose patients, and may indicate the need for decontamination even after an hour post-ingestion.
Article Abstract
Recently, there have been a number of reports concerning the utility of abdominal computed tomography (CT) for diagnosing overdose (OD). We herein report the summary and results of an analysis of these reports to assess the significance of CT for patients with OD. Searches of Ichushi (Japana Centra Revuo Medicine) and PubMed were carried out to identify articles from 1983 to 2019 using the key words "poisoning" and "abdominal computed tomography". Forty-eight cases across 15 articles were defined as subjects in this report. The average age of subjects was 46 years old, and there were 28 women. Forty-five of the 48 subjects (93.8%) had positive findings of residual drugs on CT. The finding of a high-density fluid level in the stomach was the most frequent (60.4%), followed by ill-defined high-density material in the stomach (12.5%) and high-density tablets in the stomach (10.4%). One prospective study suggested the merits of decontamination for patients with positive findings on CT even if more than 60 min had elapsed since the ingestion of drugs. Computed tomography could aid in the diagnosis of OD in comatose patients who cannot talk or who present without any other evidence of OD. In addition, a recent study revealed the merits of decontamination for patients with positive findings on the CT even if more than 60 min had elapsed since the ingestion of drugs.

Electronic address:
Objective: To explore the clinical value of combining split-bolus contrast injection with dual-energy CT(DECT) scanning technology in pediatric computed tomography urography (CTU) imaging.
Methods: A total of 128 children aged 0-17 years were prospectively selected and randomly assigned to three groups: A, B, and C. For Group A, a high-pitch flash mode was employed, where a single bolus of contrast agent was followed by four-phase scanning (noncontrast, cortex, medulla, and excretory phases).
Utility of Computed Tomography Angiography of the Head in the Management of the Blunt Trauma Patient with Intracranial Hemorrhage.

From the Department of Trauma Services (E.W.R., B.S., M.L., M.R.), OhioHealth Grant Medical Center, Columbus; and Ohio University Heritage College of Osteopathic Medicine (K.W., N.K.), Athens, Ohio.
Background: Computed tomography angiography of the head (CTAH) is not routinely obtained during the initial evaluation of patients with traumatic intracranial hemorrhage (ICH); however, it is useful for diagnosing vascular pathologies that may have led to the bleed. The aims of this study were to identify traumatic ICH patient characteristics on presentation that are associated with positive CTAH findings to elucidate which ones should prompt a CTAH and compare outcomes of patients with positive and negative CTAH findings.
Methods: This is a retrospective cohort study of 522 patients who had blunt traumatic ICH and subsequently received CTAH between January 1, 2017, and January 1, 2022.

Objective: The aim of this study was to intraindividually compare the conspicuity of focal liver lesions (FLLs) between low- and ultra-low-dose computed tomography (CT) with deep learning reconstruction (DLR) and standard-dose CT with model-based iterative reconstruction (MBIR) from a single CT using dual-split scan in patients with suspected liver metastasis via a noninferiority design.
Materials And Methods: This prospective study enrolled participants who met the eligibility criteria at 2 tertiary hospitals in South Korea from June 2022 to January 2023. The criteria included (a) being aged between 20 and 85 years and (b) having suspected or known liver metastases.
CT scan-derived pectoralis muscle parameters are closely associated with COVID-19 outcomes: A systematic review and meta-analysis.

Department of Critical Care Medicine, West China Hospital, Sichuan University, Chengdu, China.
Background: The relationships between pectoralis muscle parameters and outcomes in patients with coronavirus disease 2019 (COVID-19) remain uncertain.
Methods: We systematically searched PubMed, Embase, Web of Science and the Cochrane Library from 1 January 2019 to 1 May 2024 to identify non-overlapping studies evaluating pectoralis muscle-associated index on chest CT scan with clinical outcome in COVID-19 patients. Random-effects and fixed-effects meta-analyses were performed, and heterogeneity between studies was quantified using the I2 statistic.

Objective: To develop a predictive model for microvascular invasion (MVI) in hepatocellular carcinoma (HCC) through radiomics analysis, integrating data from both enhanced computed tomography (CT) and magnetic resonance imaging (MRI).
Methods: A retrospective analysis was conducted on 93 HCC patients who underwent partial hepatectomy. The gold standard for MVI was based on the histopathological diagnosis of the tissue.
