Job description

We are seeking a skilled Radiographer to perform DEXA scans and vascular ultrasound assessments as part of our precision cardiometabolic research programme. This position focuses on high-quality body composition imaging and vascular structure assessment for research participants with diabetes, obesity, hypertension, and cardiovascular disease.

MAIN DUTIES AND RESPONSIBILITIES

DEXA Scanning (50%)

Body Composition Assessment:

• Perform whole-body DEXA scans for body composition analysis (total body fat %, visceral adipose tissue, lean mass, bone mineral density)
• Conduct regional body composition analysis (android/gynoid fat distribution, appendicular lean mass)
• Ensure proper patient positioning and scan quality
• Perform quality control checks and phantom calibrations
• Maintain detailed scan logs and participant records

Data Management:

• Generate standardized reports from DEXA software
• Ensure accurate participant identification and data linkage
• Maintain image quality and artifact-free scans

Vascular Ultrasound (40%)

• Perform high-resolution B-mode ultrasound for carotid intima-media thickness (CIMT) measurement
• Image common carotid artery, carotid bulb, and internal/external carotid arteries bilaterally
• Acquire standardized cine-loops and still images for offline analysis
• Follow standardized protocols (Mannheim consensus guidelines)

Quality Standards:

• Ensure optimal image quality (clear intima-media interface, minimal artifacts)
• Maintain consistent probe positioning and scanning angles
• Perform regular equipment quality checks
• Achieve inter-scan reproducibility targets

Administrative & Research Support (10%)

• Schedule and coordinate imaging appointments for research participants
• Maintain equipment maintenance logs and service records
• Assist with protocol development and standard operating procedures
• Participate in quality assurance audits
• Support data collection for research studies
• Collaborate with research team on imaging protocols

REQUIRED QUALIFICATIONS

Education & Registration:

• Diploma or Degree in Diagnostic Radiography
• Current registration with Allied Health Professions Council (AHPC) Singapore or equivalent

Experience:

• Minimum 2-3 years clinical radiography experience
• Essential: Hands-on experience with DEXA scanning
• Essential: Experience with ultrasound imaging (vascular ultrasound preferred)
• Experience in research imaging or clinical trials preferred

Technical Skills:

DEXA:

• Proficient in DEXA scanner operation (GE Lunar, Hologic, or similar)
• Knowledge of body composition analysis and interpretation
• Understanding of radiation safety and quality control procedures
• Ability to position patients correctly for whole-body and regional scans
• Experience with pediatric, obese, or mobility-impaired patients preferred
• Competent in B-mode ultrasound operation
• Ability to identify and image carotid artery anatomy
• Understanding of vascular anatomy and pathology
• Skilled in optimizing image quality (gain, depth, focus settings)
• Experience with cine-loop acquisition and image storage

General:

• Experience with research databases (REDCap) preferred
• Attention to detail and quality control
• Good organizational and time management skills
• Team player in multidisciplinary research environment
• Reliable and punctual
• Flexibility to adapt to research schedule demands
