What is a Full-Body CT Scan?
A Full-Body CT scan is a comprehensive computed tomography examination that scans the entire body—from the head to the pelvis (and in some protocols, down to the lower limbs). Its primary goal is to detect any hidden lesions, underlying conditions, or tumors. The exam is often performed with contrast media to enhance visualization of blood vessels, organs, and deeper anatomical structures.

When is it recommended?
We explore the topic with Dr. Matteo Cesareni, radiologist at Ars Medica Clinic.

The main indications for a Full-Body CT scan include:

• Oncological follow-up: To monitor the spread or recurrence of a previously diagnosed cancer.

• Screening in high-risk patients: In select cases, such as heavy smokers or individuals with known genetic mutations.

• Major trauma: For urgent, comprehensive assessment.

• Comprehensive private check-ups: Particularly when vague but persistent symptoms are present.

Who are the ideal candidates?
Before recommending a Full-Body CT scan, physicians must carefully assess several factors:

• Age and medical history: Radiation exposure should not be underestimated, so this exam is reserved for patients with clear and well-considered clinical indications.

• Kidney function: In patients with renal impairment, the use of iodinated contrast agents may be contraindicated. A recent creatinine level is essential.

• Known allergies to contrast media: In such cases, the scan may be performed without contrast or with premedication, if clinically justified.

• Pregnancy: The exam is generally discouraged during pregnancy unless absolutely necessary.

The Role of Radiologist Consultation
At Ars Medica, in the heart of Northern Rome, every Full-Body CT request is reviewed in close collaboration with our team of radiologists to ensure an appropriate and patient-specific approach. This allows us to personalize the protocol—whether with or without contrast, arterial or venous phase if needed—and optimize radiation exposure according to the principles of radiation safety.
