Based on baseline survey data of ultrasound diagnostic equipment in medical institutions in Shanghai in 2025, this study aimed to analyze the current status, brand distribution, performance status, and key quality control management issues of ultrasound equipment across the city.

Using the Shanghai Ultrasound Quality Control Supervision Platform, we collected baseline data voluntarily reported by local medical institutions, covering 599 public and private medical institutions. A total of 2770 effective ultrasound devices were included. Core indicators, including equipment brand and model, configuration differences across institutional levels, correlation between purchase year and performance, and distribution of usage scope, were analyzed.

Philips, General Electric, Mindray, and Siemens were the dominant ultrasound equipment brands in Shanghai, together accounting for 71.3% of the market share. The excellent-or-good rate of the domestic brand Mindray was 97.3%, with an average service life of 3.4 years, indicating rapid market growth. Equipment configuration showed significant gradient disparities: tertiary grade-A hospitals averaged 19.7 ultrasound devices each, while non-tertiary and other medical facilities had only 2.1-6.2 devices. The citywide average service life was 5.5 years, with 9.9% (273/2770) of devices used for more than 10 years; the excellent-or-good rate of these older devices was only 78.2%-84.0%. Identified quality control management issues included uneven distribution, fragmented device models, and inconsistent evaluation standards.

To comprehensively enhance the quality control management of ultrasound diagnostic equipment in Shanghai, it is necessary to establish a tiered update mechanism, promote standardized information management, strengthen primary-care equipment support, and improve the quality control monitoring system.
