Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Diagnosis

To qualitatively and quantitatively compare two iodinated contrast administration protocols in oncologic staging CT studies of thoracic tumors, one using half the contrast dose and the other the standard dose, by analyzing the following parameters: vascular attenuation and signal-to-noise ratio (pulmonary arteries and aorta), hepatic attenuation and signal-to-noise ratio, and subjective assessment of overall image quality and image noise.

Secondary objectives 1

  1. To assess the inter-reader agreement between two readers in the evaluation of the analyzed parameters.

Conditions and MedDRA coding

Thoracic neoplasm

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 1

  1. All consecutive patients older than 18 years referred to our department for contrast-enhanced thoracoabdominopelvic CT for staging of a primary pulmonary or pleural malignancy, either at initial diagnosis or during disease follow-up, will be included.

Exclusion criteria 7

  1. Patients with known allergy or hypersensitivity to iodinated contrast media and/or any of its excipients.
  2. Renal insufficiency with an estimated glomerular filtration rate (eGFR) <30 mL/min.
  3. Patient refusal to participate in the study or inability to provide informed consent.
  4. Incomplete administration of contrast medium according to the assigned protocol due to issues with venous access, injector malfunction, central venous access, or related technical problems.
  5. Body weight <50 kg or >90 kg.
  6. Inability to perform the examination on the spectral CT scanner due to equipment malfunction, unavailability, or related technical issues.
  7. Pregnant women or women with a possibility of being pregnant.
