conclusion dt-sfp can improve the detection of relatively early bone abnormalities in acetabular and proximal femur compared with conventional radiography. dt-sfp can also observe the abnormal impact between acetabular and proximal femur. patients and methods ninety-four consecutive patients with discomfort around the hip joint underwent dt-sfp and conventional radiography. the imaging features...

background: a solitary necrotic nodule (snn) of the liver is an uncommon lesion, which is different from primary and metastatic liver cancers. objectives: to analyze the classification, ct and mr manifestation, and the pathological basis of solitary necrotic nodule of the liver (snn) in order to evaluate ct and mri as a diagnosing tool. patients and methods: this study included 29 patients with...

introduction: endoscopy is an invasive procedure and finding noninvasive alternative tools in detection of probable upper gastrointestinal (gi) tract injuries following caustic ingestion is an area of interest. the present study aimed to evaluate the screening performance characteristics of thoraco-abdominal computed tomography (ct) scan in this regard. methods: this prospective cross sectional...

background: computed tomography (ct) scan is one the most useful devices in chest imaging. ct scan can be used in mediastinal abnormality, lungs, and pleural evaluations. according to the high prevalence and different causes of pulmonary nodules, we designed this study to evaluate the prevalence and the types of pulmonary nodules in noncancerous patients who underwent chest multi-detector ct (m...

hydatid disease (hd) is a parasitic infection that is most commonly caused by the larval stage of echinococcus granulosus. unusual location for this disease can cause diagnostic and therapeutic problems. we herein report a case of sacrococcygeal hd at an unusual location in a 30-year-old woman. she was evaluated using computed tomography (ct) imaging and magnetic resonance imaging (mri) after t...

gorlin-goltz syndrome (ggs) consists of ectodermal and mesodermal abnormalities. in this case report we will investigate lower extremity lesions of ggs. a 52-year-old man with ggs underwent skull and lower extremity computer tomography. radiographic findings included cervical spondylosis, transparent areas with slurred margins, and cerebral falx calcification. tibial and fibular specific cortic...

primary small cell carcinoma of the ureter is an extremely rare disease, only several cases have been reported worldwide so far. we report a 70-year-old woman who was examined with intravenous urography and abdominal computed tomography and was diagnosed as small cell carcinoma confirmed by pathology. we describe and discuss the urography and computed tomography findings of this case.

introduction one of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...

introduction: rapid diagnosis of traumatic intrathoracic injuries leads to improvement in patient management. this study was designed to evaluate the diagnostic value of chest radiography (cxr) in comparison to chest computed tomography (ct) scan in diagnosis of traumatic intrathoracic injuries. methods: participants of this prospective diagnostic accuracy study included multiple trauma patient...

introduction: in cases of blunt abdominal traumas, predicting the possible intra-abdominal injuries is still a challenge for the physicians involved with these patients. therefore, this study was designed, to evaluate the accuracy of urinalysis in predicting intra-abdominal injuries. methods: patients aged 15 to 65 years with blunt abdominal trauma who were admitted to emergency departments wer...
