BACKGROUND BI-RADS was first developed in 1993 for mammography and in 2003 it was redesigned for ultrasonography (US). If the observer agreement is high, the method used in the classification of lesion would be reproducible. OBJECTIVES The aim of this study is to evaluate the inter- and intraobserver agreement of sonographic BI-RADS lexicon in the categorization and feature characterization o...

OBJECTIVE The aim of this study is to assess the intraobserver and interobserver reproducibility of measurement of amniotic fluid index (AFI) and single deepest vertical pool (SDVP), also known as the maximal vertical pocket. METHODS A total of 175 fetuses were evaluated. For each fetus, two observers acquired duplicate sets of AFI and SDVP. Measurement differences were expressed as actual an...

BACKGROUND Immunohistochemical (IHC) assessment of estrogen receptor (ER) and progesterone receptor (PR) status has become a routine practice to predict the likely outcome of Tamoxifen therapy. AIMS To assess the interobserver variation in scoring hormone receptor status of breast carcinoma, using the Quick Score. MATERIALS AND METHODS IHC-stained slides of breast carcinomas reported by the...

BACKGROUND AND STUDY AIMS Endoscopic mucosal resection (EMR) plays an important role in the staging of Barrett's esophagus (BE) and the evaluation of high grade dysplasia (HGD). The study aim is to assess the interobserver agreement among gastroenterologists expert in BE endotherapy, gastroenterologists without specified expertise in BE endotherapy, and gastroenterology trainees in recommending...

BACKGROUND The diagnostic yield of capsule endoscopy is vulnerable to inadequate visualization related to residual bile or chyme remaining in the lumen despite intestinal lavage. It has been challenging to determine the optimal lavage preparation of the bowel and patient diet before capsule endoscopy, as well as the timing of the procedure, because no well-accepted, validated grading system for...

OBJECTIVE: The present study was aimed at evaluating the role of computed tomography in the local clinical staging of supraglottic tumors according to the TNM classification, as well as the interobserver agreement on the detection of the tumor extent. MATERIALS AND METHODS: Thirty-nine dossiers of inpatients of Hospital Heliópolis with supraglottic squamous cell carcinoma in the period between ...

Gadolinium-enhanced MRI is a sensitive and objective means to monitor disease activity in multiple sclerosis (MS). We evaluated the interobserver agreement and the value of observer training in reporting enhancing lesions from serial MRI. Scans of 16 MS patients were evaluated by five inexperienced and five experienced observers before and after consensus formation and training. The number of l...

STUDY DESIGN Repeated-measurement design. OBJECTIVES To explore interobserver reliability of the modified physical dysfunction severity (mPDS) as a measure for impairment of the cervical spine and the modified cervical nonorganic signs (mcNOS) as a measure for behavioral signs, and to explore construct validity of the mPDS and mcNOS. BACKGROUND The PDS has been used for evaluation of treatm...

Background: The soft tissues injury in periarticular fractures of the lower extremities determines the proper time to perform bone fixation. Objetive: The aim of this study was to determine the intra and interobserver agreement in the Tscherne classification. Methods: This is a descriptive, prospective study for patients admitted to the Pablo Tobón Uribe Hospital (PTUH) with tibial plateau or t...
