Objective- The aim of this study was preparing detailed anatomic images of the thoracic cavity of the southern white-breasted hedgehog using the non-invasive computed tomography (CT) technique.Design- Descriptive study.Animals- Five southern white-breasted hedgehog (Erinaceus concolor) which is a species native to the Middle East, Anatolia, Transcaucasia, and Iran. Since some people...

t akotsubo cardiomyopathy (tcm), also known as stress-induced cardiomyopathy, is a clinical syndrome of transient left ventricular (lv) apical wall motion abnormality with relative preservation of the basal heart segments in the absence of any significant atherosclerosis. recurrence of this condition is rare. we report a postmenopausal woman, who experienced two episodes of tcm within 4 months ...

teratomas are rare germline tumors that originate from one or more embryonic germ cell layers. teratoma of the kidney is extremely rare, and less than 30 cases of primary intrarenal teratomas have been published to date. we report the main radiologic features of an unusual case of mature cystic teratoma arising from the left kidney in a two-year-old boy. a left-sided abdominal mass was detected...

conclusion considering the similar diagnostic efficacy of all voxel sizes, 300 µm voxel size can be used with adequate efficacy for detection of external root resorption defects with minimal patient radiation dose and the shortest scanning time. background selecting a voxel size that yields minimal radiation dose with no significant compromise of the diagnostic accuracy of cone beam computed to...

background coronary artery anomalies are not common, but could be very serious. objectives this study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (mdct). patients and methods the results of cardiac mdct study in 2697 consecutive patients were analyzed retrospectively. acquisition was performed by a 64-detector row ct machine. imag...

objective: the diagnosis of vertical root fracture (vrf) in endodontically treated teeth is a clinical challenge due to lack of specific clinical and radiographic signs. although radiographic evaluation such as cbct is helpful, intracanal posts can produce artifacts and may impair the quality of cbct scans. this study aimed to compare the diagnostic accuracy of different resolutions of cbct in ...

In this series a pictorial quiz pertaining to identification of normal anatomical structures and landmarks at a given level on the computed tomography (CT) is presented. An image depicting normal anatomy is followed by a series of images showing different pathologies. Readers are expected to identify and appreciate variation and changes in the normal anatomy in presence of a given pathology. Th...

 For ten years now, Siemens’ Dual Source systems have been making an impact on computed tomography and expanding its potential applications  Somatom Force and Somatom Definition Flash each perform scans using two X-ray tubes and two detectors  High temporal resolution and reduced motion artifacts support precise diagnostics for all patients – even in critical situations  Low-dose examinatio...

AIM To evaluate safety and utility of coronary computed tomography angiography (CCTA) compared to invasive coronary angiography (ICA) in new cardiomyopathy. METHODS Eighteen patients (mean age 56.5 years, 10 males) who presented for evaluation of new onset heart failure with evidence of systolic dysfunction (ejection fraction < 40%) on echocardiography and recent ICA were prospectively enroll...
