Summary
This study analyzed radiology utilization and costs at a free clinic for underserved populations. Ultrasound was the most common imaging modality, with most costs covered by donations.
Area of Science:
- Radiology
- Health Economics
- Public Health
Background:
- Underserved populations often face barriers to accessing advanced medical imaging.
- Student-run free clinics provide essential healthcare services but operate with limited resources.
Purpose of the Study:
- To assess the utilization patterns and expenditures of radiology services.
- To evaluate the role of in-kind donations in supporting imaging access.
Main Methods:
- Retrospective review of billing records from a student-run free clinic over four years.
- Categorization of radiology studies by modality and diagnostic category.
- Analysis of overall and average imaging utilization and associated costs.
Main Results:
- A total of 413 radiology studies were performed, averaging 103 per year.
- Ultrasound (46%) and radiography (30%) were the most frequent modalities.
- Total expenditures were $157,888, with 88% covered by in-kind donations; utilization increased 15% with minimal cost increase.
Conclusions:
- Ultrasound is the predominant imaging modality in this underserved setting.
- Imaging utilization was significantly lower compared to published ambulatory data.
- In-kind donations are crucial for sustaining imaging services in free clinics.

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.
