Objective(s): In this study, we aimed to describe the characteristics of portal vein tumor thrombosis (PVTT), complicating hepatocellular carcinoma (HCC) in contrast-enhanced FDG PET/CT scan. Methods: In this retrospective study, 9 HCC patients with FDG-avid PVTT were diagnosed by contrast-enhanced fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT), which is a comb...

Compressive strength represents a basic standard by which the quality of concrete is assessed. However, in view of the inherent shortcomings of the compressive strength test, current trend is towards performance oriented test using Non Destructive Methods, NDT. This is a report on a research carried out on the assessment of concrete strengths using computer tomography (CT) scan method. First, a...

INTRODUCTION The clinical profile as well as the therapeutic and diagnostic strategies for patients with pulmonary embolism, describes clinical practice in the approach of the disease. Such information, scarce in national studies, enables a better understanding of pulmonary embolism. METHODS A multicenter trial included 727 patients with pulmonary embolism who were admitted in emergency or in...

OBJECTIVE To observe the incidence of reversed halo sign in different pulmonary diseases and the pathological correspondence of reversed halo sign. METHODS Retrospectively studied the high resolution computer tomography scans of all the patients who were admitted in our department with abnormal pulmonary imaging, from 1st of January 2011 to 31st of December 2013, and all the cases with revers...

Ingestion of foreign bodies is one of the common causes of emergency department visits. History, physical examination, and noninvasive imaging such as plain radiography and computer tomography scan can guide us regarding the type and location of the ingested foreign body. Most of the patients can be managed conservatively but few may need endoscopic evaluation and treatment.

Two Greek female patients with Aicardi's syndrome are presented. The clinical picture, electroencephalogram, computer axial tomography scan, and the ophthalmological findings in these patients are described. The ocular features are emphasised because they can establish the diagnosis of this rare syndrome.

hepatosplenic candidiasis is a fungal infection, which mostly affects patientswith hematologic malignancies such as leukemia. the pathogenesis of thisinfection is not clear yet, and the liver is the most commonly affected organ.diagnosis of hepatosplenic candidiasis can be only established via biopsy,since computed tomography (ct) scan, ultrasonography, and magneticresonance imaging (mri) yield...
