Estimation of bone mineral density with hounsfield unit measurement

British Journal of Neurosurgery, 2021
Although dual-energy x-ray absorptiometry (DXA) remains the gold standard for the measurement of bone mineral density (BMD), degenerative spine and spinal instrumentation yields inaccurate results, warranting the need for optional methods.Surgical options depend on the BMD of the patients, and to accommodate this need, we compared Hounsfield unit (HU ...

Synthetic Hounsfield units from spectral CT data

Physics in Medicine and Biology, 2012
Beam-hardening-free synthetic images with absolute CT numbers that radiologists are used to can be constructed from spectral CT data by forming 'dichromatic" images after basis decomposition. The CT numbers are accurate for all tissues and the method does not require additional reconstruction.

Relationship between Hounsfield Unit in CT Scan and Gray Scale in CBCT

Journal of Dental Research, Dental Clinics, Dental Prospects, 2014
Background and aims. Cone-beam computed tomography (CBCT) is an imaging system which has many advantages over computed tomography (CT). In CT scan, Hounsfield Unit (HU) is proportional to the degree of x-ray attenuation by the tissue.

The impact of Hounsfield unit-related variables on percutaneous nephrolithotomy outcomes

Scientific Reports, 2022
We aimed to identify the association between Hounsfield Unit(HU)-related variables and percutaneous nephrolithotomy (PCNL) outcomes. We enrolled patients with single renal stones (1–3 cm) who underwent single-tract PCNL between January 2014 and October ...

In vitro Evaluation of the Relationship between Gray Scales in Digital Intraoral Radiographs and Hounsfield Units in CT Scans

Journal of Biomedical Physics and Engineering, 2017
Background: Jaw bone quality plays an essential role in treatment planning and prognosis of dental implants. Regarding several available methods for bone density measurements, they are not routinely used before implant surgery due to hard accessibility ...

The comparative survey of Hounsfield units of stone composition in urolithiasis patients

Journal of Research in Medical Sciences, 2014
Background: Non-contrast computed tomography (NCCT) is the diagnostic choice for renal stone disease. Knowing the composition of a stone before passage can help to choose a better management.

Can Deltoid Hounsfield Unit/Supraspinatus Hounsfield Unit Predict Postoperative Rotator Cuff Retear? [PDF]

Orthop Surg
This study carries significant implications for the management of postoperative retear following arthroscopic rotator cuff repair. We introduced a novel predictive marker—the Deltoid‐to‐Supraspinatus muscle HU (Hounsfield Unit) ratio—and developed several predictive models by integrating multiple risk factors.

Assessment of Hounsfield unit in the differential diagnosis of odontogenic cysts

Dentomaxillofacial Radiology, 2021
Objectives: The purpose of this study was to evaluate the usefulness of Hounsfield unit (HU) assessment with multislice-CT in the differentiation of radicular cysts (RCs), dentigerous cysts (DCs) and odontogenic keratocysts (OKCs). Methods: In total, 307 odontogenic cysts (RCs, DCs and OKCs) were included in this study.
