Abstract
Objective: To assess the diagnostic performance of contrast-enhanced ultrasound (CEUS) for detecting abdominal metastases in patients with gastrointestinal stromal tumors (GISTs), with a comparison to conventional ultrasonography (US) and contrast-enhanced computed tomography (CE-CT).
Methods: This retrospective study enrolled 53 patients with pathologically confirmed abdominal metastases from gastrointestinal stromal tumors (GISTs), who underwent US, CEUS, and CE-CT examinations at our institution between January 2022 and January 2025. The diagnostic performance of CEUS was systematically evaluated and compared with US and CE-CT according to pathological diagnostic criteria.
Results: CEUS showed significantly higher sensitivity than US (88.68% vs. 45.28%; p < 0.05). Notably, CEUS achieved comparable performance to CE-CT (sensitivity: 88.68% vs. 94.34%; p > 0.05). No statistically significant differences were observed between CEUS and CE-CT in lesion perfusion characteristics, including enhancement pattern (p > 0.05), intensity (p > 0.05), and homogeneity (p > 0.05).
Conclusions: CEUS demonstrates superior diagnostic performance to US in detecting abdominal metastases from GISTs, with efficacy comparable to CE-CT. Given its radiation-free nature and procedural simplicity, CEUS represents a valuable imaging modality for the clinical assessment of GIST metastases.
期刊介绍:
The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography.
The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents.
JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
