Summary
Performing PET/CT and contrast-enhanced CT in a single session significantly reduces costs for both institutions and patients. This integrated approach offers a more economical and efficient method for cancer staging and restaging.
Area of Science:
- Radiology and Nuclear Medicine
- Health Economics
- Oncology
Background:
- Positron Emission Tomography/Computed Tomography (PET/CT) and contrast-enhanced (c.e.) CT are crucial diagnostic tools in oncology.
- Current practice often involves performing these imaging modalities as stand-alone procedures.
Purpose of the Study:
- To quantify and compare the economic impact of single-session PET/CT and c.e. CT versus separate imaging sessions in cancer patients.
- To evaluate cost-effectiveness from both institutional and patient perspectives.
Main Methods:
- A cost-minimization analysis was conducted on 145 oncological patients undergoing PET/CT and c.e. CT.
- Patients were divided into two groups: single-session (innovative method, N.=72) and separate sessions (traditional method, N.=73).
- Institutional costs (staff, materials, equipment, utilities) and patient costs (travel, accommodation, lost productivity) were assessed.
Main Results:
- The single-session approach was found to be more cost-effective, saving institutions €106 per test compared to the traditional method.
- Patients also benefited economically, with savings of €21 per patient and a reduction of 3 work hours in lost productivity.
- Reduced travel and housing expenses contributed significantly to patient cost savings.
Conclusions:
- Combining PET/CT and c.e. CT into a single examination session is a more cost-effective strategy in oncological patient care.
- This integrated method lowers overall healthcare expenditures by decreasing both institutional operational costs and patient-related expenses.
- The findings support the adoption of single-session imaging for improved economic efficiency in cancer diagnostics.

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
