CONTEXT The standard criteria used to evaluate tumor response, the Response Evaluation Criteria in Solid Tumors (RECIST), were developed to assess tumor shrinkage after cytotoxic chemotherapy and may be limited in assessing response to biologic agents, which have a cytostatic mechanism of action. OBJECTIVE To validate novel tumor response criteria based on morphologic changes observed on comp...

OBJECTIVE This study investigates the prognostic value of (18)F-FDG PET/CT qualitative therapy assessment (Hopkins criteria) in patients with head and neck squamous cell carcinomas (HNSCCs) with residual neck nodes after definitive chemoradiation therapy and compares the Hopkins criteria with anatomic nodal size and morphologic features for prediction of survival outcomes. MATERIALS AND METHO...

OBJECTIVE To assess the outcome on management recommendations of a comparative approach vs a morphologic approach in evaluating dermoscopic images of lesions from a series of patients with multiple nevi. DESIGN In a 2-step study, 6 experienced dermoscopists were asked to provide management recommendations (excision or follow-up) for a series of lesions from patients with multiple nevi based o...

The aim was to clarify whether enhancement effects of the liver parenchyma in the hepatobiliary phase (HP) of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MR imaging were correlated with the morphological grading of the severity in cirrhosis. A total of 62 patients with chronic hepatitis or cirrhosis underwent Gd-EOB-DTPA-enhanced MR imaging. Relative enhan...

Hepatic sinusoid plays a vital role in human cavernous hemangioma of the liver (CHL), and its morphologic investigation facilitates the understanding of microcirculation mechanism and pathological change of CHL. However, precise anatomical view of the hepatic sinusoid has been limited by the resolution and contrast available from existing imaging techniques. While liver biopsy has traditionally...

Insulation co-ordination and the risk of failure for insulation can be predicted if critical flashover (CFO) and insulation withstand voltages are known. The paper aims at using the statistical method of evaluating the critical flashover and the withstand voltage for an airgap distance of 10cm. The work was carried out with a point-plane electrode (needle point) arrangement using air as the die...

Hypereosinophilic syndrome is defined as a peripheral blood eosinophil count ? 1.5 109/L associated with tissue or organ damage. Eosinophilic disorders represent group of pathological conditions heterogeneous pathophysiology, clinical presentation and prognosis. The disease prognosis based on identifying the subtype mechanism eosinophilia. It important to assess degree damage diagnostics that d...
