Eligibility
Age
18 Years to 99 Years
Inclusion criteria
Inclusion criteria: * 18 years of age or older * A solid primary tumour anywhere in the body and solid, noncalcified nodules in the pulmonary parenchyma on previous CT scans suspected for pulmonary metastases, according to radiological reports * Two lung nodules that do not abut vessels or pleura with a two dimensional diameter between 5 and 10 mm within a distance of each other of 16 cm in the craniocaudal direction
Exclusion criteria
Exclusion criteria: * Immobility (not able to stand up and get off the scanner table) * Patients who received local pulmonary treatment: o Radiotherapy o Excision o Ablation * Patients with radiologically suspected lymphangitis carcinomatosa or consolidations around the nodules. * Patients who only have calcified pulmonary nodules or nodules that about vessels or pleura.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main endpoint of this study is the upper limit of the 95% confidence interval of repeated semi-automated nodule volume measurements of both CT scanners. | — |
Secondary
| Measure | Time frame |
|---|---|
| * To assess the variability in manual calliper two-dimensional measurements of pulmonary nodules. * To assess the effect of subjective image quality, structure delineation and segmentation, and nodule type on the variability in volume of the nodule measurements. | — |
