AIMS The aim of this study was to evaluate the capability of intraoperative ultrasonography (IOUSG) in identifying malignant intraparenchymal tumors during surgical intervention. SETTINGS AND DESIGN Forty patients with intrinsic malignant tumors were evaluated by using IOUSG. MATERIALS AND METHODS A real-time ultrasound scanner with a 3- or 5-MHz transducer was used for this study in all ca...
Background: The oral cavity is one of the most common sites for various tumors and tumor like lesions. Among the malignant lesions, squamous cell carcinoma is single most common malignant lesion of this region. Aims and Objectives: To study the histopathology of different tumor and tumor like lesion of oral cavity with relation to age, sex , site and risk factors involved in these lesions. Mate...
BACKGROUND We found that (18)F-2-fluoro-2-deoxy-D-glucose ((18)F-FDG) uptake in malignant lesion was enhanced, and it was decreased in the inflammatory lesion after the use of peroxisome proliferator activated receptor-γ (PPAR-γ) agonist in our previous preclinical study. The purpose of this study was to investigate the effect of PPAR-γ agonist on malignant lesions in clinical (18)F-FDG positro...
Space occupying liver lesions usually present with abdominal pain or abnormal physical findings, such as a palpable abdominal mass or distention. Liver lesions identified in children include benign and malignant neoplasms, inflammatory masses, cysts and metastatic lesions. Two-thirds of liver lesions in children are malignant. Hepatoblastoma accounts for two-thirds of malignant liver tumors in ...
OBJECTIVE To assess the diagnostic accuracy of triphasic spiral CT in differentiating benign from malignant focal tumoral liver lesions. METHODS The study was conducted in Department of Radiology of Aga Khan University Hospital and Sind Institute of Urology and Transplantation, Karachi from Feb 2006 to Feb 2007. By convenient sampling, 45 patients found to have focal tumoral liver lesions wer...
OBJECTIVE To better characterize the dermoscopic patterns of mucosal lesions in relation to the histopathologic characteristics. DESIGN Retrospective and observational study. SETTING Fourteen referral pigmented lesion clinics in 10 countries. PATIENTS A total of 140 pigmented mucosal lesions (126 benign lesions, 11 melanomas, 2 Bowen disease lesions, and 1 metastasis) from 92 females (66%...
BACKGROUND We evaluated the differential diagnosis of solitary pulmonary lesions on magnetic resonance imaging. AIMS To investigate the value of diffusion weighted imaging on the differential diagnosis of solitary pulmonary lesions. STUDY DESIGN Randomized prospective study. METHODS This prospective study included 48 solitary pulmonary nodules and masses (18 benign, 30 malignant). Single ...
BACKGROUND AND PURPOSE Differential diagnosis between malignant tumors and chronic infections in the masticator space remains challenging. The purpose of the study was to categorize various changes of both lesions by using single-voxel 1H-MR spectroscopy. MATERIALS AND METHODS Twenty-four masticator space lesions, 7 chronic infections, and 17 malignant tumors were assessed with 1H-MR spectros...
this study was undertaken to examine the ability of spect in differentiation of a pulmonary lesion suspecions of lung cancr. a total of 170 patients with suspected lung cancer were studied. a dose of tl-201 chloride {148-296 mbq) was injected intravenously and tomographic early and delayed scans were obtained at 15 miniutes and 3 hours post injection, respectively. delayed tl-201 spect visulize...
