Study Information:
-
Sample size used for the test set and the data provenance:
- Test Set Sample Size: Not explicitly stated as a numerical count of patients or images. The text mentions "sample clinical images" were obtained.
- Data Provenance: The study involved "Internal scans within GE Healthcare facility." This indicates the data was likely prospective and collected specifically for this filing. The country of origin is implicitly India ("Wipro GE Healthcare Pvt Ltd, Bangalore, INDIA").
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not provided in the document. The filing focuses on technical and safety equivalence, with clinical images used internally for verification rather than a formal clinical trial with expert interpretation for ground truth.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- This information is not provided. Given the nature of the "internal scans" for "sample clinical images" and the absence of explicit expert review processes, it's highly probable that a formal adjudication method was not used in the context typically seen in AI device studies. The primary goal was to demonstrate image production and quality consistent with the predicate, not diagnostic accuracy against a ground truth.
-
If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No, an MRMC comparative effectiveness study was not done. This submission is for a medical device (MRI coil), not an AI-assisted diagnostic tool. The document explicitly states: "The subject of this premarket submission, 1.5T 4CH Flex Coil did not require external clinical studies to support substantial equivalence."
-
If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- Not applicable. This device is an MRI coil, which is a component of an imaging system, not a standalone algorithm or AI. Its performance is evaluated on its ability to acquire images, not to perform interpretations.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For the "sample clinical images" obtained from internal scans, the concept of a formal "ground truth" (e.g., pathology, expert consensus on disease presence) in the context of diagnostic accuracy is not applicable or stated. The "ground truth" for the coil's performance was likely related to the expected image quality and signal-to-noise ratio compared to engineering specifications and the predicate device, demonstrated through visual inspection of the images themselves rather than an independent diagnostic gold standard.
-
The sample size for the training set:
- Not applicable. This is a hardware device (MRI coil), not a machine learning algorithm that requires a training set.
-
How the ground truth for the training set was established:
- Not applicable. (See point 7).
