Introduction: Computed tomography (CT) imaging is the choice of investigation for evaluation of extent of tumor under the mucosa, locally and regionally. This study was undertaken to assess the accuracy of preoperative CT imaging in the staging of carcinoma of the larynx and hypopharynx.   Materials and Methods: In this retrospective study, all cases who were clinically (c) staged T3–T4 and w...

Introduction: Squamous Cell Carcinoma (SCC) is the most common head and neck malignancy. To decrease the side effects of treatment and mortality from disease relapse, careful staging for the proper treatment plan is necessary. The main purpose of this prospective study is to compare the diagnostic value of Computed Tomography (CT) and Magnetic Resonance Im-aging (MRI) in oral SCC and its lymph ...

To investigate the role of Computer Tomography (CT) in the esophageal cancer surgery. 97 cases confirmed by pathology as esophageal cancer were retrospectively analyzed with preoperative Computer Tomography images and intraoperative situation. Tthe Computer Tomography can accurately display the thickness and length of the lesion segment esophageal wall, the relations between tumor and the aorta...

We report a 31-year-old male with history of left forearm neuroma surgically removed, consulting for supraclavicular bultoma congruent the supradiaphragmatic lymphoproliferative syndrome in computed tomography (CT) scan. [18F]FDG PET/CT images helped to establish most diagnostic yield lesion biopsy, and allowed an accurate staging neurofibromatosis (NF) disease, leading appropriate therapeutic ...

OBJECTIVE [(18)F]Fluorodeoxyglucose positron emission tomography-computerized tomography (PET-CT) scan is a tool widely used in the diagnosis and staging of lung cancer. Referral bias is present when the results of a diagnostic study affect the decision to proceed with definitive testing. This bias artificially increases the sensitivity and decreases the specificity, and may inappropriately alt...

UNLABELLED Accurate staging of Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) is important for treatment management. In this study, the utility of 2-[18F]fluoro-2-deoxy-D-glucose (FDG) whole-body PET was evaluated as an imaging modality for initial staging or restaging of 7 HD and 11 NHL patients. METHODS Whole-body PET-based staging results were compared to the patient's clinical st...

ct image quality has been affected by many factors such as kvp, ma, exposure time, alogorithm and section thickness. gantry tilt has the main role in visualization of the temporal bone anatomic structures. in this study, we tried to optimize these factors to determine the best gantry tilt. this study was performed on the human skull phantom and then extended to 15 patients. the phantom was made...

Positron emission tomography/computed tomography (PET/CT) is an important tool to identify occult melanoma metastasis. To date, it is controversial which patients with primary cutaneous melanoma should have staging PET/CT. In this retrospective analysis of more than 800 consecutive patients with cutaneous melanoma, we sought to identify factors predictive of PET/CT positivity in the setting of ...

Staging of non-small-cell lung cancer is a multidisciplinary process involving imaging, endoscopic and surgical techniques. Accuracy is vital in order to avoid false-positive interpretations leading to a false stage III or IV diagnosis in early stage patients, or false-negative findings leading to a false early stage diagnosis in patients with mediastinal lymph node disease. CT scan offers grea...

Objective This study aimed to determine whether there is a clinical-radiological correlation in chronic rhinosinusitis (CRS), to compare operative findings with those of computed tomography (CT) imaging, and to determine the importance of a CT score and staging in management of CRS. Methods This study is a prospective study. Adult patients meeting diagnostic criteria for CRS were prospectivel...
