results thirty-four patients were hyperglycemic and 127 non diabetic. sensitivity, specificity, positive predictive value and negative predictive value of fdg-pet/ct were 90%, 88%, 87% and 91% in non diabetic and 82%, 92%, 95% and 73% in hyperglycemic patients, respectively. overall, the accuracy was higher in non diabetic than hyperglycemic patients (89% vs. 85%). conclusions accuracy of fdg-p...

Introduction:Spontaneous pneumomediastinum, pneumothorax, and subcutaneous emphysema are rare, but serious complications of inflammatory myopathies and occur more commonly in DM than PM. complications of dermatomyositis (DM) and polymyositis (PM), both of which can be fatal. Case Report:A 20-year-old woman was admitted with neck pain, dyspnea, cough, and fever. She had been diagnosed with derma...

Diseases affecting the small airways are difficult to detect by traditional diagnostic tests. Widespread involvement is needed before symptoms and abnormalities on pulmonary function testing or chest radiography become apparent. Obstruction of the bronchioles may be detected indirectly by computed tomography (CT) because regional under-ventilation results in reduced perfusion which in turn is s...

An 85-year-old man, who had previously undergone coronary bypass surgery, was subjected to a computed tomography (CT) scan because of an echocardiographic suspect of massive pulmonary embolism. A huge aortic arch aneurysm compressed the pulmonary arteries (Fig. 1). Sudden cardio-respiratory failure required mechanical ventilation. At this stage, surgeons considered him inoperable for high risk....

Introduction During mechanical ventilation, reduction of expiratory pressure may trigger heterogeneous processes of derecruitment, collapse and overdistension of airspaces. However the relationship of such processes with precise regional location inside the lung has not been fully studied in vivo. Synchrotron Radiation Computed Tomography (SRCT) can provide in vivo regional images of the lung a...

maxillary sinus aplasia and hypoplasia are rare conditions that can cause symptoms such as headaches and voice alteration. the majority of patients are asymptomatic, but these conditions must be noticed for importance of differential diagnosis such as infection and neoplasms. conventional radiographs could not differentiate between infl ammatory mucosal thickening, neoplasm, and hypoplasia of t...

Renal cell carcinoma (RCC) accounts for only 3% of adult malignancies, and the lung is the most common site of metastasis of this tumor, which may be accompanied by pleural metastasis. However, solitary pleural involvement is very rare and its presentation with dyspnea as the first manifestation of RCC is extremely rare.We describe a 39-year-old male with episodes of dyspnea dating back 6...

conclusions a high index of suspicion is essential for early detection of ddr and dddr. patients with high impact injuries or surrounding organ damage should be followed with serial clinical examinations, follow-up radiologic assessments, and even re-exploration in situations highly suspicious for diaphragmatic injuries. introduction diaphragmatic rupture (dr) is an uncommon, potentially seriou...

Understanding spatial and temporal patterns of bioirrigation induced by benthic fauna ventilation is critical given its significance on benthic nutrient exchange and biogeochemistry in coastal ecosystems. The quantification of this process challenges marine scientists because faunal activities and behaviors are concealed in an opaque sediment matrix. Here, we use a hybrid medical imaging techni...

Introduction: Orbital metastasis of prostate cancer (PC) is very rare and even more unique in castration-resistant PC (CRPC). In this scenario, choline positron emission tomography/computed tomography (choline PET/CT) is the gold-standard restaging method of choice available in our setting, and new anti-androgens treatments show improvement in overall survival. Case presentation: We report the...
