The objective of this study was to evaluate whether Doppler ultrasound (DUS) is of additional value to gray-scale ultrasound (GSUS) in predicting the benign or malignant nature of thyroid nodules. A total of 1,502 solid thyroid nodules ≥ 10 mm were evaluated. Suspicious vascularity (predominantly or exclusively central blood flow) was observed in only 5% of the nodules. This finding showed 96% ...

PURPOSE We assessed the application of the choroidal vascularity index (CVI) in the follow-up of Vogt-Koyanagi-Harada disease (VKH) patients derived from image binarization of enhanced depth imaging optical coherence tomography (EDI-OCT) images with Fiji software. Our secondary objective was to derive the retinochoroidal vascularity index based on en face fundus fluorescein and indocyanine gree...

Previous perfusion studies of the rotator cuff have demonstrated an area of bypovascularity in the distal part of the supraspinatus tendon. This has been implicated in the pathogenesis ofits rupture. We performed a quantitative histological analysis of the vascularity of the tendons ofsupraspinatus and infraspinatus. Vessel number, size and the percentage of the tendon occupied by vessels were ...

Bone quality is an important factor that may determine implant success. In addition to the other parameters that define bone quality, vascularity plays a vital role in the process of osseointegration of dental implants. Laser Doppler flowmetry (LDF) is an appropriate method for assessment of tissue vascularity at the level of microcirculation. It is non-invasive, painless and well accepted by t...

In lung transplant recipients, the submucosal vascular plexus of the airway wall potentially represents one of the key structures of graft injury. Narrow band imaging is a novel endoscope technique that allows visual enhancement of the mucosa vasculature. It was our aim to investigate the ability of narrow-band imaging in combination with computerized image analysis to quantitatively assess air...

We reviewed recent in vivo studies of the real-time changes in the vasculature of the follicle wall during selection of the dominant follicle as well as during ovulation in cows. Changes in follicle diameter and vascularity were determined by transrectal ultrasonography. Blood flow within the walls of the two largest follicles was detected at the time of wave emergence (largest follicle=5 mm in...
