On Dose Efficiency of Modern CT-scanners in Chest Scans

Germany958 participantsStarted 2021-10-07

Plain-language summary

CT scans of the chest / thorax are of great importance both in the initial diagnosis and in the follow-up of pulmonary or thoracic diseases. As an example, CT angiography of the pulmonary arteries (CTPA) is worldwide considered to be gold standard test in patients with a suspicion for pulmonary embolism. The aim of this study is to measure and compare dose efficiency of modern CT scanners for unenhanced and contrast-enhanced scan protocols of the chest/thorax. Patients who are referred for a CT of the chest/thorax will be randomly assigned to one of the three CT scanners currently in use at our institution.

Inclusion Criteria: * patient is referred for an unenhanced CT OR contrast-enhanced CT of the chest/thorax confirmed by a board-certified radiologist ('justifying indication' according to German/European radiation protection law) AND * patient is at least 18 years of age AND * patient (is able to give informed consent and) has given informed consent. Exclusion Criteria: * high degree of medical urgency (i.e. patient cannot be consented for iv contrast according to routine procedures) * known or suspected pregnancy, or lactating . contraindications for contrast agent (renal failure, allergy, hyperthyroidism)

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
