BACKGROUND The purpose of this study was to assess the relationship of CT-perfusion (CTP), 18F-FDG-PET/CT and histological parameters, and the possible added value of CTP to FDG-PET/CT in the initial staging of lung cancer. METHODS Fifty-four consecutive patients (median age 65 years, 15 females, 39 males) with suspected lung cancer were evaluated prospectively by CT-perfusion scan and 18F-FD...

Since its introduction in the early nineties as a promising functional imaging technique in the management of neoplastic disorders, FDG-PET, and subsequently FDG-PET/CT, has become a cornerstone in several oncologic procedures such as tumor staging and restaging, treatment efficacy assessment during or after treatment end and radiotherapy planning. Moreover, the continuous technological progres...

background since tuberculosis (tb) is a major public health problem that is a leading cause of mortality and morbidity among infectious diseases worldwide, early diagnosis and treatment are important to control an effective tuberculosis (tb) and also the increasing number of patients with atypical manifestations of active tb. it suggests more evaluation for active tb in fibrotic lesion in ct sc...

abstract   background: the purpose of this study was to evaluate the significance of the q angle with respect to the patella position. we assess the correlation between the q angles (calculated by clinical exam) in different positions and ct indices (with more impression on tttg).   method: atotal number of 68 knee joints of 50 cases entered the study. clinical examination was used to measure q...

conclusions because this incident may have occurred during the patient’s neonatal period, it may be a case of child abuse. in spite of the very limited number of cases in the literature, having a stepmother, a stepfather, or a babysitter, being the youngest child, or having family members who suffer from psychiatric disorders, (especially if these relatives are responsible for child care), livi...

background and aims. current infiltration techniques for achieving anesthesia in dental procedures are not applicable in posterior mandibular region because of its dense cortical bone. the aim of this study was to evaluate the efficacy of a specific infiltration anesthesia in posterior mandibular teeth instead of inferior alveolar nerve block for restorative procedures. materials and methods. c...

background & aim: dental implants should be surrounded with at least 1mm bone. assessing ridge width is an important part to achieve this goal. the use of ridge mapping to assess bone levels available avoids some of the problems associated with ct-scanning. the aim of this study was to assess the accuracy of ridge-mapping compared to ct-scan in determination of bony ridge widths. methods & mate...

introduction: pulmonary involvement secondary to systemic sclerosis (ssc) is the major cause of morbidity and mortality in ssc patients. we designed this study to determine the correlation of important lung function parameters with lung high resolution ct (hrct) scan findings.materials and methods: thirty–two consecutive diffuse ssc patients with pulmonary fibrosis were enrolled in this cross-s...

introduction: the selection of   optimal treatment of obstructive nephrouropathy requires information about the functional status of each kidney. nuclear renal scanning objectively measure differential renal function, multiple studies have demonstrated the role of assessment of renal perfusion and gfr with triphasic ct. the aim of this study is to assess the role of ct based on renal parenchyma...

metastasis of gastroesphageal junction (gej) adenocarcinoma in skeletal muscle is rare and primary sites for skeletal muscle metastases are usually lung, renal and colorectal cancer. we have encountered with the first case report of solitary psoas muscle metastasis of gej adenocarcinoma. here we describe a 65 years old man was diagnosed with gej adenocarcinoma in tertiary hospital, tehran, iran...
