BACKGROUND A dermoscopic method based on the absence of a pigment network and the presence of at least one of six positive features has been described for diagnosis of pigmented basal cell carcinoma (BCC). OBJECTIVE To evaluate the observers' global agreement and interobserver agreement on each dermoscopic parameter of the method recently proposed. METHODS Dermoscopic images of 56 pigmented...

BACKGROUND AND PURPOSE Reproducibility in identifying the fibrous cap (FC) of carotid artery plaques by noncontrast-enhanced MRI has been shown to be poor. The objective of this study was to assess the reproducibility of multisequence MRI, including contrast-enhanced images, in assessing FC status. METHODS Forty-five symptomatic patients with 30% to 69% carotid artery stenosis underwent a mul...

BACKGROUND AND PURPOSE Because evidence-based articles are difficult to recognize among the large volume of publications available, some journals have adopted evidence-based medicine criteria to classify their articles. Our purpose was to determine whether an evidence-based medicine classification used by a subspecialty-imaging journal allowed consistent categorization of levels of evidence amo...

AIM To assess the reproducibility of clinical diagnosis of occlusal caries using unaided visual examination and examination with an operating microscope (16 x magnification) and to determine the agreement between these 2 methods. MATERIALS AND METHODS Three experienced dentists used unaided visual examination and an operating microscope to grade, according to a standard caries rating scale, a...

BACKGROUND AND PURPOSE Several studies have reported on the clinical utility of DWI in head and neck cancer, but none of these studies compared HASTE with EPI-DWI in patients with head and neck cancer. The aim of our study was to compare detection and delineation of primary tumors and lymph nodes by using HASTE and EPI-DWI techniques in patients with HNSCC. MATERIALS AND METHODS Twelve patien...

AIM To establish consensual definitions of anoperineal lesions of Crohn's (APLOC) disease and assess interobserver agreement on their diagnosis between experts. METHODS A database of digitally recorded pictures of APLOC was examined by a coordinating group who selected two series of 20 pictures illustrating the various aspects of APLOC. A reading group comprised: eight experts from the Sociét...

BACKGROUND The grade of gastric mucosa atrophy caused by Helicobacter pylori (H. pylori) infection is closely associated with the risk of gastric cancer, especially of the intestinal type. Interobserver and intraobserver agreement for endoscopic gastric mucosa atrophy in subjects with H. pylori-uninfected, currently infected and past infected was investigated. METHODS Endoscopic images of 91 ...

OBJECTIVE To assess the feasibility of contrast-enhanced spectral mammography (CESM) of the breast for assessing the size of residual tumors after neoadjuvant chemotherapy (NAC). MATERIALS AND METHODS In breast cancer patients who underwent NAC between 2011 and 2013, we evaluated residual tumor measurements obtained with CESM and full-field digital mammography (FFDM). We determined the concor...

OBJECTIVE To evaluate the performance of magnetic resonance imaging (MRI) in detecting periosteal reactions and to compare MRI and conventional radiography (CR) in terms of the classification of periosteal reactions. MATERIALS AND METHODS Retrospective study of 42 consecutive patients (mean age, 22 years; 20 men) with a confirmed diagnosis of osteosarcoma or Ewing's sarcoma, MRI and CR images...

Background: Management of endometrial precancerous lesions has been of much debate due to inconsistencies in their classification, natural history and histologic diagnosis. Endometrial hyperplasia constitutes a wide range of histomorphologic features associated with high intra and interobserver diagnostic variability. Although traditional microscopic diagnosis is by far the most applicable meth...
