Performance criteria for quantitative ultrasonology and image parameterisation

Clinical Physics and Physiological Measurement, 1990
For the purpose of assessing and comparing the practical performance of various specific approaches to quantitative tissue characterisation, three sets of performance criteria are proposed, relating respectively to contrast resolution, spatial resolution, and speed of presentation. In each case numerical performance targets are suggested: in particular

The accuracy of ultrasonography in classification of groin hernias according to the criteria of the unified classification system

Hernia, 2008
The modern concept of type-related individualized groin hernia surgery imposes a demand for precise and accurate preoperative determination of the type of groin hernia. The aim of this prospective study was to evaluate the accuracy of ultrasonography in classification of groin hernias, according to the criteria of the unified classification system ...

[Evaluation of doppler ultrasonography criteria for the differential diagnosis of pancreatic tumors].

Ultraschall in der Medizin (Stuttgart, Germany : 1980), 2001
In order to improve the differential diagnosis of pancreatic lesions, dopplersonographic criteria for the tumours were evaluated.35 patients diagnosed by conventional ultrasound as having a tumour of pancreas were further investigated by B-mode sonography, fundamental and echo-enhanced power-Doppler sonography focusing on specific properties of the ...

Pancreatic Cancer Staging: Endoscopic Ultrasonography Criteria for Vascular Invasion

Gastrointestinal Endoscopy Clinics of North America, 1995
Endoscopic ultrasound (EUS) is the most sensitive imaging test available for examining the pancreas and associated structures. Small (< 2 cm) pancreatic malignancies can be detected with accuracy rates of more than 90%. Several EUS criteria have been proposed for their ability to diagnose malignant venous invasion.

A Prospective Study on Endoscopic Ultrasonography Criteria to Guide Management in Upper GI Submucosal Tumors

Polish Journal of Surgery, 2011
Endoscopic ultrasonography (EUS) can differentiate between impression and submucosal tumor (SMT) but it is not known whether EUS criteria can reliably guide management. The aim of this prospective study was to assess an approach to recommend removal versus follow-up investigation based on clinical and EUS criteria, with respect to the predictive values

Classification of Uterine Anomalies by 3-Dimensional Ultrasonography Using ESHRE/ESGE Criteria: Interobserver Variability

Reproductive Sciences, 2018
To evaluate the interobserver repeatability of the coronal view measurements and classification of the uterine malformations (UM) according to the ESHRE/ESGE consensus by transvaginal three-dimensional ultrasound (3D-US).89 transvaginal 3D-US volumes acquired during the last two years at Delta Ecografía in Madrid, Spain, were selected from our archive ...

Diagnostic Criteria and Accuracy of Categorizing Malignant Thyroid Nodules by Ultrasonography and Ultrasound Elastography with Pathologic Correlation

Ultrasonic Imaging, 2015
Thyroid nodules are a common medical and surgical concern. Thyroid ultrasound (US) is the primary imaging modality used for initial evaluation and assortment of nodules for fine needle aspiration (FNA) cytology/biopsy. Ultrasound elastography (USE) is believed to improve the diagnostic accuracy of US in distinguishing benign from malignant nodules ...

[Gastroschisis: Prenatal ultrasonography and obstetrical criteria for predicting neonatal outcome].

Gynecologie, obstetrique & fertilite, 2017
Prenatal diagnosis of complex laparoschisis is difficult and yet it is associated with a significantly increased morbidity and mortality. The aim of the study was to define ultrasonographic factor and obstetrical criteria to predicting adverse neonatal outcome.Retrospective cohort study over 10 years, of 35 gastroschisis cases in CHU of Reims (France).
