Intended Use
BriefCase-Quantification is a radiological image management and processing system software indicated for use in the analysis of CT exams with contrast, that include the abdominal aorta, in adults or transitional adolescents aged 18 and older. The device is intended to assist appropriately trained medical specialists by providing the user with the maximum abdominal aortic diameter measurement of cases that include the abdominal aorta (M-AbdAo). BriefCase-Quantification is indicated to evaluate normal and aneurysmal abdominal aortas and is not intended to evaluate post-operative aortas. The BriefCase-Quantification results are not intended to be used on a stand-alone basis for clinical decision-making or otherwise preclude clinical assessment of cases. These measurements are unofficial, are not final, and are subject to change after review by a radiologist. For final clinically approved measurements, please refer to the official radiology report. Clinicians are responsible for viewing full images per the standard of care.
Device Description
BriefCase-Quantification is a radiological medical image management and processing device. The software consists of a single module based on an algorithm programmed component and is intended to run on a linux-based server in a cloud environment. The BriefCase-Quantification receives filtered DICOM Images, and processes them chronologically by running the algorithm on relevant series to measure the maximum abdominal aortic diameter. Following the AI processing, the output of the algorithm analysis is transferred to an image review software (desktop application), and forwarded to user review in the PACS. BriefCase-Quantification produces a preview image annotated with the maximum diameter measurement. The diameter marking is not intended to be a final output, but serves the purpose of visualization and measurement. The original, unmarked series remains available in the PACS as well. The preview image presents an unofficial measurement which is not final, and the user is instructed to review the full image and any other clinical information before making a clinical decision. The image includes a disclaimer: "Not for diagnostic use. The measurement is unofficial, not final, and must be reviewed by a radiologist." BriefCase-Quantification is not intended to evaluate post-operative aortas.

Primary Endpoint
The algorithm performance showed that the mean absolute error between the ground truth measurement and algorithm was 1.52 mm (95% Cl: 1.20 mm, 1.83 mm). Because the mean absolute error estimate was below the prespecified performance goal, the study's primary endpoint was achieved.

The reported similar mean absolute error [the subject device: 1.52 mm (95% C1: 1.20 mm, 1.83 mm); the predicate device: 1.95 mm (95% Cl: 1.59 mm, 2.32 mm)] demonstrates comparable performance.

Performance testing results for the Bland-Altman analysis is reported below:

The mean difference between the ground truth compared to the algorithm output is 0.58 mm, indicating that there is little to no bias between the two measurements, demonstrating the study's secondary endpoint was achieved.

Summary of Technological Characteristics

The subject BriefCase-Quantification device is substantially similar to the predicate device BriefCase-Quantification (K230534). Both devices are radiological computer-aided medical image management and processing software devices, intended to aid in measurement of radiological images.

Both devices are artificial intelligence, deep-learning algorithms incorporating software packages for use with compliant scanners, PACS, and radiology workstations. Both are intended to assist appropriately trained medical specialists by providing the user with the maximum abdominal aortic diameter measurement. The subject device presents key slice with the long and short axis of the aorta in the reformatted slice with the maximum measurement, while the predicate device presents key slice in axial format.

The main difference between the subject and predicate device is the performance, due to its training on a larger data set, in that the subject device demonstrates improved performance over the predicate device. With regards to the indications for use, for the predicate device the indications refer to axial measurement of cases that include the abdominal aorta. For the subject device, measurement is orthogonal to the blood flow, therefore the word axial was omitted from the indications for use statement.

Both devices raise the same types of safety and effectiveness questions. A table comparing the key features of the subject and predicate devices is provided below:

Performance Data

Pivotal Study Summary

Aidoc conducted a retrospective, blinded, multicenter study with the BriefCase-Quantification software to evaluate the software's performance in providing maximum diameter measurements of the abdominal aorta in CT images in 162 cases, from 6 US-based clinical sites, both academic and community centers, compared to the ground truth, as determined by three US board-certified radiologists. The cases collected for the pivotal dataset were all distinct in time and/or center from the cases used to train the algorithm.

Primary Endpoint

The algorithm performance showed that the mean absolute error between the ground truth measurement and algorithm was 1.52 mm (95% Cl: 1.20 mm, 1.83 mm). Because the mean absolute error estimate was below the prespecified performance goal, the study's primary endpoint was achieved.

The reported similar mean absolute error [the subject device: 1.52 mm (95% C1: 1.20 mm, 1.83 mm); the predicate device: 1.95 mm (95% Cl: 1.59 mm, 2.32 mm)] demonstrates comparable performance.

As can be seen in Table 2, the mean age of patients whose scans were reviewed for BriefCase-Quantification of the Abdominal Aortic Measurement was 62.8 years, with a standard deviation of 19.6 years. Gender distribution was 46.9% male, and 53.1% female (Table 3). Scanner distribution can also be found in Table 4 below.

Performance testing results for the Bland-Altman analysis is reported below:

The mean difference between the ground truth compared to the algorithm output is 0.58 mm, indicating that there is little to no bias between the two measurements, demonstrating the study's secondary endpoint was achieved.

In summary, performance validation data, combined with a comparison of mean absolute error metric with the reference device demonstrated equivalent performance.

Conclusions

The subject and predicate BriefCase-Quantification for Abdominal Aortic Measurement (M-AbdAo) devices are intended to aid in medical image management and processing of radiological images in CT.

BriefCase-Quantification of M-AbdAo is as safe and effective as the predicate device cleared under K230534. BriefCase-Quantification has similar intended uses and similar indications, technological characteristics, and principles of operation as its predicate device. The minor differences in the indications for use and in the technological characteristics do not alter the intended use of the device and do not affect its safety and effectiveness when used as labeled. Performance data demonstrate that the subject device is as safe and effective as the predicate device. Thus, BriefCase-Quantification of M-AbdAo is substantially equivalent to the previously cleared BriefCase-Quantification of M-AbdAo device (K230534).
