Trial summary

The investigators aim to address this issue with novel image quantification methods using CZT-based SPECT, which is capable of dynamic data acquisition and therefore feasible for the quantification of the coronary flow. Read more about this study

About this study

The investigators aim to address this issue with novel image quantification methods using CZT-based SPECT, which is capable of dynamic data acquisition and therefore feasible for the quantification of the coronary flow. The investigators will use kinetic modeling techniques to design a study that allows the absolute flow quantification. To make this study practical, the investigators will develop a protocol that includes the acquisition of both the rest and stress scan within the same scan that is shorter than 30 minutes. The SPECT-measured flow will be validated against the flow measured with cardiac MRI scans. Patients with high CAD risk will be recruited for the clinical trial. Data from these human subjects will be used for determination of the performance of the developed algorithm. With the proposed rapid scan with absolute quantification capabilities, the investigators expect to increase the diagnosis accuracy while maintaining the patient throughput.

Questions about this trial

What is this clinical trial studying?

An observational study of Quantitative Analysis of SPECT MPI, run by Chang Gung Memorial Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Correlation between SPECT- and MRI-measured flow values (time frame: through study completion, an average of 3 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Dec 2016.
