background: patient radiation doses from computed tomography (ct) are increasing due to the number of ct examinations performed every day. the aim of this study was assess and evaluate patient radiation doses for adult’s common ct examinations to derive local diagnostic guidance levels for common ct examinations. materials and methods: volume and weighted computed tomography dose index (ctdivol...

Diversity in data is critical for the successful training of deep learning models. Leveraged by a recurrent generative adversarial network, we propose CT-SGAN model that generates large-scale 3D synthetic CT-scan volumes (\({\ge }224\times 224\times 224\)) when trained on small dataset chest CT-scans. offers an attractive solution to two major challenges facing machine medical imaging: number g...

Invagination is a kind of intestine disease in children and it is occurred between 2 upto 14 years old. This is a report of 17 months infant with intussusception due to trauma. The patient had admitted to emergency department because of motor vehicle accident and because of abdominal pain, abdominal computed tomography (CT) scan was done.

This article reports a pelvic hydatid cyst in a 10-year-old boy who initially presented with right flank pain. Computed tomography (CT) revealed a cystic lesion containing internal densities, which was found to be a hydatid cyst between the bladder and rectum during surgery. The lesion was excised and sent to a pathology laboratory for further examination.

ABSTRACTNeuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. It is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. Neuroimaging modalities include X-ray computed tomography (CT), magnetic resonance imaging (MRI), single photon emis...

Swyer-James-MacLeod syndrome (SJMS) is an uncommon obliterative lung disease that is radiologically characterized by hyperlucency of a part of or the entire lung. A 33-year-old man presented to our hospital for chest tightness. A chest X-ray revealed unilateral hyperlucency of left lower lung, and contrast-enhanced computed tomography (CT) of the chest disclosed a hyperlucent left lung without ...

two cases of hydatid cysts of the orbit causing unilateral exophthalmos are reported. diagnosis were suspected by means of computed tomography (ct) and confirmed at operation. ct changes are described and its value in diagnosis of this lesion particularly in the endemic areas is stressed.

Multidetector-row computed tomography (MDCT) can be used to quantify morphological features and investigate structure/function relationship in COPD. This approach allows a phenotypical definition of COPD patients, and might improve our understanding of disease pathogenesis and suggest new therapeutical options. In recent years, magnetic resonance imaging (MRI) has also become potentially suitab...
