Assessing the bone quality of your patients is just a few clicks away

Quibim is proud to introduce its new advanced methodolgy to assess bone quality and fracture risk: QTS (Quality of Trabecular Structure). The need for a reliable approach for the characterization of trabecular microarchitecture is evident, as conditions and diseases related to trabecular bone quality and structure are becoming a focal point of precision medicine. Millions of dollars are spent in bone fracture care and prevention, which in many cases represent a grave danger to the patient health. In this scenario, can we rely upon available methods to predict bone fractures? Regrettably, the answer is no. Or so it was. Before we introduce QTS in detail, let’s first review some of the available methods to evaluate fracture risk.

DEXA Bone Mineral Density (BMD) limitations as a fracture predictor are widely known. However, despite its glaring shortcomings it’s still considered as the gold standard in clinical practice. The WHO developed the FRAX tool hoping to improve the low ratio of success of BMD as a predictor, and, while it improves sensibility and specificity assessing fracture risk, it’s still not satisfactory enough for it to be used as a stand-alone predictor in clinical practice or clinical trials.

In an attempt to fill this void in the search of a reliable predictor, new imaging biomarkers that guarantee to provide the needed sensibility and specificity have been developed. Trabecular Bone Score (TBS®) by Medimaps is a fracture risk predictor using DEXA as a source. TBS® performs a gray level analysis (textures) on the DEXA images to determine bone integrity. But, is DEXA adequate for this task? Unlike regular XR, in which it’s possible to assess the trabecular structure, DEXA’s low radiation is not enough for trabeculae differentiation. In addition, DEXA (like XR) represents a 3D structure as a projection onto a plane, losing spatial information.

Other medical imaging modalities are much more adequate for bone analysis and the subsequent fracture risk evaluation. Thanks to advanced computing models, Quibim has developed a new imaging biomarker that uses either magnetic resonance (MR), computerized tomography (CT) or X-ray imaging for a detailed characterization of the trabecular structure. QTS (Quality of Trabecular Structure) by Quibim introduces several advantages over other analysis methods:

  • Real extraction of the trabecular bone microarchitecture: bone volume, trabecular thickness, trabecular separation…
  • Information of the complexity of the structure: fractal analysis
  • 3D spatial information, not only in plane (only CT and MR)
  • 3D reconstruction of the trabecular bone (only CT and MR)
  • Optional mechanical analysis (only CT and MR, with QTS+)
  • QTS Score comprises all this information in a single score for a rapid and accurate characterization of the bone structure.

This groundbreaking analysis method is already available at our cloud web platform: Quibim Precision. Below we detail how to analyze your study in a few simple steps.

Quibim Precision allows the upload of studies in Dicom format. The upload process is easy, intuitive and 100% secure, guaranteeing the patient confidentiality thanks to Quibim’s anonymization and encryption system. The whole process is performed without the need of installing any additional software. To start, click on the green “Upload Study” button to the right of the website.

00

The platform will then ask for Dicom studies selection. With Google Chrome, we can drag and drop the study folder directly to the dotted box. With any other browser, we need to select the Dicom files to be uploaded.

00b

Once the Dicom folders have been selected, Quibim Precision allows the pre-visualization of the study to choose which sequences we wish to upload. In this case, we need a CT, an X-ray or a 3D T1 MR.

After the selection, the files will be anonymized and encrypted. Quibim Precision will ask for an encryption password before the upload process starts. The user needs to preserve this password, as it’s needed for patient traceability.

00c

After the upload process is completed, we click on the “Analyze Study” button of the study we want to evaluate.

01

This will take us to the detailed view of the study, where we can perform all actions related to it. First of all, we will choose among all the available sequences the one to be analyzed and its Quibim standard name. In this case, the name of the sequence is “Linear Attenuation [1/cm] (3035)”, which corresponds to the standard name “High Resolution CT”.

02

Next, we open the embedded Dicom viewer by clicking on “View”. Thanks to this viewer we can draw the ROI that will be used for the analysis. The viewer allows drawing 3D ROIs, first drawing a 2D rectangular ROI, and then selecting the slices on which it should be replicated. Clicking on “Apply” and “Save and go back” will store the ROI and it will be used for the analysis.

04b

Finally, we should choose which analysis method we’ll use among all the available apps in Quibim Precision. In this case we’ll click on the “Start Analysis” button of the “3D Bone microarchitecture – QTS Score” app. The analysis process will then start, and the user doesn’t need to perform any other action than checking the results.

03

The results of the analysis are available on the view of the study. Once the analysis is completed we can check them by clicking on the “View Study” button on the “Processed Biomarkers” section.

05

We can examine the 3D reconstruction images and the numeric results of the extracted imaging biomarkers on the results view. Furthermore, we can download them and the structured report in pdf format, which includes all the generated data in a compact, easy to read way.

Our experience at BIO 2016 and USA tour

We were delighted to be present at past BIO conference in San Francisco (Moscone Center), from 6th to 9th of June, with a booth in the Spanish pavillion. Our presence was due to the incorporation of QUIBIM in the ICEX next program, the Spanish program that assists SME’s in their internationalization.

I can now confirm that the meeting covered my expectations and I agree with the definition in their website: The BIO International Convention (BIO) attracts over 15,000 biotechnology and pharma leaders who come together for one week of intensive networking to discover new opportunities and promising partnerships. This event covers a wide spectrum of life science and application areas including drug discovery, biomanufacturing, genomics, biofuels, nanotechnology and cell therapy.

The attendees were also variate:

  • One-third of BIO attendees come from outside the U.S.
  • 2,500+ CEO’s from leading biotech companies
  • More than 70% of attendees are either Managers, Directors, C-Level or Executive Management.
  • All company sizes: 33% of attendees are from companies with more than 500 employees and 40% are from companies with fewer than 50 employees.

Our first event in the congress was the session “Spain Kicks off 2016 BIO International Convention” in a charming venue: The Ferry Building. A session were we were able to learn from leading experts on how to select the appropriate path, develop and execute our strategy successfully, as well as best practices and what we need to understand in any approach. High level executives from TTS Global Initiative, Breakout Labs, CytomX, GeronIRB Barcelona, pH PharmaRoche, Stanford University and the Thiel Foundation participated in the panel.

In the BIO convention, we had a total of 23 one-to-one partnering meetings organised. The meetings were very well organised and distributed and having the possibility of discussing 30 minutes with potential customers, providers or investors to explore further ways of collaboration justifies our presence in the congress. New business opportunities that are now being executed arose.

After BIO convention, we decided to spend a pair of days at Case Western Reserve Medical Center in Cleveland, visiting Dr. Pablo Ros, member of our advisory board and Chairman at the Department of Radiology in UH Case Medical Center. The purpose of the visit was to discover the biomedical engineering department and the projects that are being performed. Among the short meetings I shared with senior reserchers, I must highlight the meeting with Dr. Mark Griswold, the promoter of the MRI fingerprinting technique.

In summary, we will probably repeat our attendance at BIO conference due to the success of networking.
