CT Scan for Mesothelioma


A CT scan is a sophisticated imaging technique that produces detailed three-dimensional images of the body using X-rays and computer technology. By capturing multiple images of the same organ from various angles, the CT scan creates a cross-sectional view of bones, blood vessels, and tissues.

During the procedure, the patient lies down on a table and gradually enters a cylindrical machine often referred to as the “donut.” CT scans can reveal evidence of tumors or abnormalities in the tissues.

To enhance visibility within the body, an iodine fluid, also known as radiocontrast or contrast, may be administered. Patients can either drink the iodine fluid or receive it through an injection into their veins.

For patients suspected of having pleural mesothelioma, CT scans are the primary imaging method. Research has shown that 94% of pleural mesothelioma patients who underwent a CT scan displayed pleural thickening, while 74% showed signs of pleural effusion.

The reported sensitivity, specificity, and accuracy of CT scans for mesothelioma are 53%, 100%, and 68%, respectively. This means that the test can correctly detect 53% of positive mesothelioma cases, accurately identify 100% of individuals without the cancer, and provide an overall accurate diagnosis in 68% of cases, regardless of whether mesothelioma is present.

Before the CT scan, patients are required to drink the contrast liquid or receive it via an intravenous injection to ensure clear imaging. Additional images may be taken at a later time after the procedure.

The procedure typically lasts between 15 and 60 minutes, and if the patient requires contrast fluid, some preparation time is necessary. Fortunately, the CT scan procedure is not painful.
