background and objective: computerized tomography and fluoroscopic computerized tomography are amongst the methods used for guiding needle biopsy processes; however, fluoroscopic computerized tomography demonstrates the images during the process of biopsy. this study aims to compare and contrast the success of biopsy under guide of computerized tomography and fluoroscopic computerized tomograph...

the purpose of this study was to identify the anatomic structures of the abdominal region of cat throughcomputed tomography (ct) to be used by veterinary radiologists, clinicians and surgeons. the abdominalregion of four cats were scanned twice, with and without using contrast medium in a same position, usinghigh-resolution imaging protocol. slice intervals were 11 mm and were adjusted so that ...

conclusion according to our findings, ct-guided percutaneous drainage is a safe and effective procedure in the treatment of abdominal abscess and fluid collection. results the average age of the patients was 54 years (range 12 to 79), including 21 (51%) men and 20 (49%) women. the common signs and symptoms were pain (83%) and fever (80.5%). the most prevalent abdominal abscess etiology was prev...

introduction: computed tomography (ct) is an imaging technique with gives us an opportunity to review cross sections of the body in live animals. in veterinary medicine although ct is mostly used for diagnostic purposes in small animals, but in recent years ct also has been used as a non invasive modality in non clinical studies. jebeer gazelle (gazella bennettii) is one of the species of the g...

background: methanol is a colorless and poisonous liquid that is commonly used as an industrial and household solvent. methanol poisoning is a rare but extremely hazardous form of in toxication that affects the central nervous system and causes visual disorder, drowsiness, seizures and coma.  case presentation: a 29-years-old man with methanol intoxication presented with drowsiness and acidosis...

Using the island divertors (ID) of W7-AS and W7-X and the helical divertor (HD) of LHD as examples, the paper presents a comparative divertor transport study for three typical helical devices of different machine-size following two distinct divertor concepts, aiming at identifying common physics issues/effects for mutual validation and combined studies. Based on EMC3/EIRENE simulations supporte...

Question: How does dual-section helical computed tomography compare to selective pulmonary arteriography (SPA) in diagnosing pulmonary embolism (PE)? Design: A prospective cross-sectional study. Setting: Cardiology and intensive care units of a university teaching hospital in Paris, France. Patients: Two hundred and four consecutive patients were clinically suspected of having an acute PE. Of t...

Hughes and Stovin first reported a syndrome consisting of multiple pulmonary artery aneurysms and venous thrombosis in 1959. Here, we encountered a 42-year old woman who had hemoptysis revealing a Hughes-Stovin syndrome. Helical computed tomography showed multiple pulmonary artery aneurysms with pulmonary thromboembolism. The patient was treated with steroid therapy, cyclophosphamide and antico...

PURPOSE To study the imaging exams more commonly used for abdominal aortic aneurysms evaluation - ultrasonography, conventional computerized tomography, helical computerized tomography and nuclear magnetic angioresonance - comparing the preoperative measurements reached by those radiological methods with the measurements made during the surgical procedures. METHODS Patients who had indication...
