trauma is the most common reason in 1-34 years olds. in patient with multiple traumas, the head is the most common involved part. the importance of computed tomography (ct scan) in diagnosis of brain trauma is well established and ct of the brain is a choice method. finding lesion in brain traumatic patient is very important so goal of this study is finding of brain ct scan in traumatic patient...

OBJECTIVE This study sought to assess the real incidence of pN2 among patients with non-small-cell lung cancer (NSCLC) (cN0) with negative mediastinal uptake of 2-deoxy-2-(18F)-fluoro-o-glucose (FDG). METHODS During 30 consecutive months (January 2007-May 2009), all patients with NSCLC scheduled for surgery in our unit had a preoperative FDG-positron emission tomography (PET)/computed tomogra...

PET-CT scan has demonstrated to be very effective in lung cancer diagnosis and staging, but lung cancer has multiple ways of presentation, which can lead to an error in diagnosis imaging and a delay on the beginning of specific treatment. We present a case of a 77-year-old man with an initial PET-CT scan showing high 18F-FDG intake, suggesting a bilateral pneumonia, who was finally diagnosed of...

A 50-yr-old man presented with intermittent hemoptysis and was diagnosed small cell lung cancer. (18)F-FDG PET/CT for staging demonstrated extensive hypermetabolic lesions throughout the skeleton and liver. Interestingly, skeletal muscles of limbs, mediastinum, bowel, and especially brain showed very low FDG uptake. Because of some characteristics in common with super scan on skeletal scintigra...

Abstract Introduction PSMA PET-CT (PSMA) is a relatively new development in PCa imaging. We report the role and impact of management both primary recurrent since our service's inception January 2020. Method A retrospective analysis database was conducted. All patients underwent conventional imaging (CI) [CT/MRI & Bone scan] as well. Indications for were: Data collected included demographics...

The article by Sherman et al is a broad review of the recent developments in the treatment of patients with small-cell lung cancer who present with limited disease. Intially, the authors emphasize that the increasing use of more intensive and refined staging procedures, such as computed tomography (CT) scan and, more recently, positron-emission tomography (PET) scan, have resulted in stage migr...

anaplastic thyroid carcinoma is an uncommon, highly aggressive malignancy usually presenting in the elderly. an eighteen year old boy was recently diagnosed as anaplastic carcinoma of the thyroid.  pet/cect scan performed for staging, revealed a large fdg avid heterogeneously enhancing thyroid mass with bilateral jugular venous thrombosis, which also showed increased fdg uptake, thus pointing t...

introduction bolus is a soft and resilient material which is used for increasing skin dose or to even out the irregular patient contour. the main property of various materials used presently as bolus is the water-equivalent electron density. ethyl methacrylate is used as a soft-liner in dentistry and its physical and chemical properties are proved to be nontoxic for human body. the goal of this...

Two hundred seventy-five cranial computed tomography (CT) scans performed on 179 patients with malignant melanoma were reviewed. Of the 101 patients with confirmed cerebral metastases, CT demonstrated lesions in 93. In 72% of these, areas of increased attenuation were present in the precontrast scan. These lesions also enhanced after contrast infusion. There was a direct correlation between the...

chronic rhinosinusitis (crs) is a common disease which is usually diagnosed clinically, considering the combination of natural history, physical examination and imaging studies. this study aimed to evaluate the clinical value of routine postoperative histopathologic examination (pohe) in patients with a clinical diagnosis of chronic rhinosinusitis with polyposis (crswp), or without polyposis (c...
