Skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. The skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. Focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. The patients with skull meta...

hepatic inflammatory pseudotumor (ipt) is a rare non-neoplastic process of unknown etiology, generally following a benign inflammatory condition. it is often mistaken as an either primary or metastatic malignancy in imaging studies. we report a 48 year-old female with numerous target lesions (2-4 cm) seen on high resolution ultrasound, spiral ct scan, and mri in all liver lobes compatible with ...

orbital lynphangioma is a low-flow or no-flow vascular malformation. it is a congenital and isolated hemodynamic lesion in which the clinical presentation and onset are related to orbital, peri-orbital or intracranial involvement. in addition, history of previous trauma and upper respiratory tract infection are important predictor factors. high resolution mri, doppler ultrasound and ct-scan are...

conclusions it seems that in advanced cases of cf, at older ages and with lack of appropriate medical care, severity, prevalence, and appearance of lung lesions do not follow a definite specific pattern. therefore, a similar study is suggested in older patients with a larger sample size for comparison of results. results all studied patients had bronchiectasis and peribronchial wall thickening ...

the presence of anatomic variations of paranasal sinuses must be noted in order to attain a full understanding and accurate diagnosis of chronic sinusitis. the frequency of anatomic variations in chronic sinusitis is different in various studies. the purpose of this study is to assess the frequency of anatomic variations in chronic sinusitis patients admitted to otolaryngology ward of shahid sa...

introduction in ct imaging, metallic implants inside the tissues cause metal artifact that reduce the quality of image for diagnosis. in order to reduce the effect of this artifact, a new method with more appropriate results has been presented in this research work. materials and methods the presented method comprised of following steps: a) image enhancement and metal areas extraction, b) sinog...

introduction: pulmonary embolism (pe) is a common lethal disease that its clinical symptoms may be seen in many other diseases. computed tomography pulmonary angiography (ctpa) is a valuable diagnostic modality for detection of pe. in addition, it can accurately detect the other diseases with clinical symptoms similar to pe. the aim of this study is to evaluate the frequency of pe and nonemboli...

Cardiac imaging with multiple-row detector computed tomography (CT) has become possible due to rapid advances in CT technologies. Images with high temporal and spatial resolution can be obtained with multiple-row detector CT scanners; however, the radiation dose associated with cardiac imaging is high. Understanding the physics of cardiac imaging with multiple-row detector CT scanners allows op...
