Evaluation of a Pneumotachograph (SPI) for the Production of PET and CT Acquisitions Synchronized With Breath for the Assessment of Extension of Lung Cancer - Full Text View

Purpose

This is a pilot study, single-center, prospective, open-label, to assess the acceptability and performance of the experimental medical device (SPI) used during an imaging examination (PET / CT 4D imaging in synchronized mode centered on the thorax). Each patient will be its own control, since the imaging examination will be synchronized simultaneously with the two systems: tested Medical Device (SPI) and reference Medical Device(RPM).

Condition	Intervention
Non Small Cell Lung Cancer Lung Nodule	Device: PET/CT 4D imaging in a synchronized mode centered on the thorax.

Study Type:	Interventional
Study Design:	Allocation: Non-Randomized Intervention Model: Single Group Assignment Masking: Open Label Primary Purpose: Diagnostic
Official Title:	Evaluation of a Pneumotachograph (SPI) for the Production of PET and CT Acquisitions Synchronized With Breath for the Assessment of Extension of Lung Cancer

Primary Outcome Measures:

Feasibility of the PET/CT synchronized exam with SPI device ("success" or "failure" ) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
feasibility is evaluated in a composite end point (success will be obtained in case of concomitant success of the 4 sub-criteria assessment):
1. Tolerance / acceptability of the patient to breathe into SPI throughout the examination)
2. Detection of breath cycle of the patient by measuring dCycleSpi (dCycleSpi = Number of synchronization signals emitted by SPI / total number of breath cycle * 100).
3. Accuracy of detection of inspiratory peak amplitudes with SPI medical device: by measuring dtSpi (dtSpi = standard deviation of the time lag between synchronization signals and maximum inspiratory amplitude for each cycle).
4. Production of images with a correct segmentation of BTV during PET/CT synchronized exam with SPI device"

Secondary Outcome Measures:

Measure of dCycleRpm (dCycleRpmi = Number of synchronization signals emitted by RPM / total number of breath cycle * 100) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
Accuracy of detection of maximum inspiratory amplitudes with RPM medical device: evaluated by measuring dtRpm [ Time Frame: 2 years ] [ Designated as safety issue: No ]
dtRpm = standard deviation of the time lag between synchronization signals and maximum inspiratory amplitude for each cycle
Measure of BTVrpm (= biologic tumoral volume) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
