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 Al processing, the output of the algorithm analysis is transferred to an image review software (desktop application), and forwarded to user review in the PACS. The BriefCase-Quantification produces a preview image annotated with the maximum axial 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 and not final measurement, 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.

Yes
The device description explicitly states "Following the Al processing, the output of the algorithm analysis is transferred to an image review software". Additionally, the "Mentions AI, DNN, or ML" field is marked as "Yes".

No.
The device is described as a "radiological image management and processing system software" intended to "assist appropriately trained medical specialists by providing the user with the maximum abdominal aortic axial diameter measurement." It explicitly states that "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" and "not for diagnostic use." This indicates it's an aid for measurement and analysis, not a device that directly treats, cures, mitigates, or prevents diseases.

No

The text explicitly states multiple times that the device's measurements are "unofficial," "not final," and "not for diagnostic use," and clarifies that it is intended to "assist" medical specialists but not for "stand-alone basis for clinical decision-making."

Yes

The device description explicitly states that BriefCase-Quantification is a "radiological medical image management and processing device" and that 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." This indicates it is purely software performing image processing and analysis.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • BriefCase-Quantification's Function: BriefCase-Quantification analyzes radiological images (CT scans), which are external to the body. It processes these images to measure the diameter of the abdominal aorta.
  • No Biological Samples: The device does not interact with or analyze any biological samples from the patient.

Therefore, based on the provided information, BriefCase-Quantification falls under the category of a radiological image processing and analysis system, not an In Vitro Diagnostic device.

No
The provided text does not contain any explicit statement that the FDA has reviewed, approved, or cleared a Predetermined Change Control Plan (PCCP) for this specific device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Pivotal Study Summary
Aidoc conducted a retrospective, blinded, multicenter study with the BriefCase-Quantification software to evaluate the software's performance in providing maximum axial diameter measurements of the abdominal aorta in CT images in 160 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 1.95 mm (95% Cl: 1.59 mm, 2.32 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: 1.95 mm (95% C1: 1.59 mm, 2.32 mm); the reference device: 1.6 mm (95% Cl: 1.5 mm, 1.7 mm)] demonstrates comparable performance.
Additional descriptive statistics and Bland Altman analysis were also reported in the labeling.

Comparison of Technological Characteristics

The subject BriefCase-Quantification of the Abdominal Aortic Measurement (M-AbdAo) is substantially similar to primary predicate Viz RV/LV (K221100) and is similar to reference device Al-Rad Companion (Cardiovascular) (K183268), as explained below.

The subject, predicate and the reference devices are radiological computer-aided medical image management and processing software. All devices are artificial intelligence, deep-learning algorithms incorporating software packages for use with compliant scanners. PACS, and radiology workstations. The predicate Viz RV/LV and the reference Al-Rad Companion (Cardiovascular) evaluate images from CT scanners as does the proposed device for BriefCase-Quantification of the Abdominal Aortic Measurement (M-AbdAo). The subject, predicate and reference devices produce similar outputs that includes a diameter measurement of an anatomical organ image series (Abdominal aorta; Left and right ventricles of the heart; aorta - respectively).

The proposed device for BriefCase-Quantification of the Abdominal Aortic Measurement (M-AbdAo) has similar technology and design as the primary predicate device and the reference device, and similar indications for use, i.e., all three devices are intended to aid in measurement of radiological images. The subject, the predicate Viz RV/LV and the reference Al-Rad Companion (Cardiovascular) devices raise the same types of safety and effectiveness questions. A table comparing the key features of the subject device, the primary predicate device and the reference predicate device is provided below.

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 1.95 mm (95% Cl: 1.59 mm, 2.32 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: 1.95 mm (95% C1: 1.59 mm, 2.32 mm); the reference device: 1.6 mm (95% Cl: 1.5 mm, 1.7 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 66.8 years, with a standard deviation of 14.8 years. Gender distribution was 58.8% male, and 40.0% female (Table 3). Scanner distribution can also be found in Table 4 below.

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

Conclusions

The subject BriefCase-Quantification of the Abdominal Aortic Measurement (M-AbdAo), the predicate Viz RV/LV and the reference device Al-Rad Companion (Cardiovascular) are intended to aid in medical image management and processing of radiological images in CT. The subject, predicate and the reference devices are not intended to be used as diagnostic devices. All three devices are software packages with similar technological characteristics and principles of operation, incorporating deep learning AI algorithms that process images. They additionally operate in parallel to the standard of care workflow in the sense that they have the potential to allow accurate measurement and facilitate the standard manual workflow.

In both devices, the labeling instructs the user that the results are not intended to be used on a stand-alone basis for clinical decision making or otherwise preclude clinical assessment. The subject and reference device have similar clinical indications and show substantially similar performance.

The BriefCase-Quantification of the Abdominal Aortic Measurement (M-AbdAo) device is thus substantially equivalent and is as safe and effective to the Viz RV/LV and Al-Rad Companion (Cardiovascular).
