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. OBJECTIVE An in vitro investigation of correlation between average gray scale in direct digital radiographs and Hounsfield units in CT-Scan pr...

Objective: Differences in bone density before and after regenerative endodontic treatment were examined in teeth with periapical lesions in Hounsfield Units (HUs) by using Cone Beam Computed

OBJECTIVES This study was undertaken: (1) to evaluate the usefulness of unenhanced computed tomography (CT), magnetic resonance imaging (MRI) and CT guided biopsy for the characterization of adrenal masses in patients with operable non-small-cell lung cancer (NSCLC) and (2) to evaluate the situations in which CT guided biopsy is absolutely necessary before potentially curative resection of NSCL...

Extracorporeal Shock Wave Lithotripsy (ESWL) is still the treatment of choice for most renal and upper ureteric stones; however the outcome depends on multiple factors. The objective of this study was to investigate the effects of stone density, as measured by Hounsfield Units (H.U) by non-contrast Computerized Tomography (CT), stone size and stone location on ESWL treatment outcome of urinary ...

The computed tomographic (CT) attenuation values and magnetic resonance (MR) signal intensities of simulated acute subarachnoid hemorrhage were compared systematically. In vitro MR and CT measurements (T1, T2, and Hounsfield units) were made of mixtures of normal human cerebrospinal fluid (CSF) and normal heparinized blood, ranging from 0% to 100% by volume. The mixtures were measured in a plex...
