Professional Assessment of Ultrasound Equipment Maintenance and Quality Assurance at Diagnostic Centres in Niger Delta States

Ultrasound equipment quality assurance and preventive maintenance are essential for ensuring that diagnostic imaging examinations produce consistent image quality and that equipment performance parameters remain within manufacturers' specified operational ranges. In the Niger Delta states of Rivers, Delta, Bayelsa, and Cross River, the quality assurance status of ultrasound equipment across public and private diagnostic centres requires professional assessment. This study professionally assesses ultrasound equipment maintenance and quality assurance practices at diagnostic imaging centres in Niger Delta states. A cross-sectional professional audit is applied across 20 diagnostic centres, documenting preventive maintenance schedules, quality assurance test procedures performed, transducer performance assessment frequency, manufacturer service contract status, and equipment failure rate records. Structured interviews with 60 radiographers and biomedical engineers provide maintenance practice data. An equipment quality assurance compliance score is computed for each centre. Descriptive statistics are performed in SPSS. Literature from Niger Delta radiology contexts identifies absence of preventive maintenance contracts, degraded transducer performance undetected by users, and reliance on reactive breakdown maintenance as the predominant equipment management deficiencies. The AIUM Routine Quality Assurance for Diagnostic Ultrasound Equipment and the IPEM Report 107 ultrasound quality assurance guidelines provide the professional standards. Findings are expected to reveal low preventive maintenance compliance and significant transducer performance degradation across public-sector facilities. Recommendations address a shared biomedical engineering maintenance service contract for Niger Delta public hospitals, structured quarterly ultrasound quality assurance testing, and budget provisions for preventive maintenance.
