• Submission Type: Traditional
• Regulation: 21 CFR 892.1170
• Device Class: Class 2

Intended Use

The APEX for QDR X-Ray Bone Densitometers is indicated for the estimation of bone mineral density (BMD), comparison of measured variables obtained from a given QDR scan to a detabase of reference values, the estimation of fracture risk, vertebral deformity assessment, body composition analysis, and discrimination of bone from prosthetics using the Hologic ODR® X-Ray Bone Densitometers. IVA scans are intended for the visualization or quantitative assessment of vertebral body deformities. IVA also allows the visualization of abdominal aortic calcifications and, if present, clinical correlation may be advised since abdominal aortic calcification may be associated with cardiovascular disease.

Device Story

APEX 2.0 Software functions as an optional software package for Hologic QDR X-Ray Bone Densitometers. It processes X-ray scan data to estimate bone mineral density (BMD), assess fracture risk, perform body composition analysis, and distinguish bone from prosthetic materials. The software enables vertebral deformity assessment (IVA) and visualization of abdominal aortic calcifications. Used in clinical settings by healthcare professionals, the software transforms raw scan inputs into quantitative metrics and visual outputs. These outputs assist clinicians in diagnosing bone health, evaluating cardiovascular risk markers (aortic calcification), and monitoring treatment efficacy. The device provides standardized reference comparisons to aid clinical decision-making.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and intended use compared to the predicate device.

Technological Characteristics

Software-based image processing and analysis tool for QDR X-Ray Bone Densitometers. Operates as an add-on software module. Utilizes established densitometry algorithms for BMD estimation, vertebral deformity assessment, and body composition analysis. Connectivity via integration with Hologic QDR hardware.

Indications for Use

Indicated for patients requiring bone mineral density (BMD) estimation, fracture risk assessment, vertebral deformity assessment, body composition analysis, or discrimination of bone from prosthetics via QDR X-Ray Bone Densitometers. IVA scans indicated for visualization/quantitative assessment of vertebral deformities and abdominal aortic calcifications.

Regulatory Classification

Identification

A bone densitometer is a device intended for medical purposes to measure bone density and mineral content by x-ray or gamma ray transmission measurements through the bone and adjacent tissues. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

Dear Mr. Cowell:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Image /page/2/Picture/10 description: The image is a circular logo with the letters "FDA" in the center. Above the letters, the years "1906-2006" are printed. Below the letters, the word "Centennial" is printed in a stylized font. The logo is surrounded by a dotted border.
