سابقه و هدف: با توجه به اندیکاسیون کارگذاری پیچ های داخل پدیکل و آمار متفاوت فراوانی جاگذاری ناصحیح آن و عوامل مرتبط با آن در تحقیقات کشورهای خارجی به منظور تعیین فراوانی جاگذاری ناصحیح پیچ های داخل پدیکل و عوامل مرتبط با آن و نقش آن در پیش آگهی بیماران این تحقیق در مراجعین به بیمارستان امام حسین (ع) در سال های 1386- 1384 انجام شد. مواد و روش ها: تحقیق با طراحی case- series انجام گرفت. کلیه بیم...
M e t h o d s Data sources: MEDLINE (1985 to 2003), EMBASE/Excerpta Medica (1985 to 2003), bibliographies of relevant studies, and contact with experts. Articles on helical CT were limited to those published between 1990 and 2003, and articles on V/Q scan were limited to those published between 1985 and 2003. Study selection and assessment: Englishlanguage studies that used helical CT or V/Q sc...
Recently, the usefulness of three-dimensional CT angiography (3D-CTA) using helical CT has been reported. Although 3D-CTA has been applied for neurosurgical diseases, especially for surgical planning, it has not done for emergency patients because of the long time required for image reconstruction and location of a helical CT scanner. We studied emergency patients with SAH, and compared the 3D-...
Introduction: Accurate evaluation of femoral and tibial torsion is essential for children or adult with legs deformity, becuse incorrect legs morphogenesis can lead to pathological situation. CT scan is commonly used for the measurement of skeletal bone parameters. But, disability in imaging from standing and sitting posture and absorb dose of patients are deficits of this meth...
Adenosine-induced stress myocardial perfusion imaging using dual-source cardiac computed tomography.
OBJECTIVES This study sought to determine the feasibility of performing a comprehensive cardiac computed tomographic (CT) examination incorporating stress and rest myocardial perfusion imaging together with coronary computed tomography angiography (CTA). BACKGROUND Although cardiac CT can identify coronary stenosis, very little data exist on the ability to detect stress-induced myocardial per...
Background: Cardiac CT imaging is gaining in popularity. When imaging the heart with CT, additional structures are visualized, including the lungs. Whether the lung fields should be evaluated during cardiac CT imaging is controversial. Some cardiology groups believe that analyzing the lung fields will only lead to increased patient anxiety and increased costs without clinical benefit. Objective...
conclusions in hemodynamically stable patients with a ruptured raml, early detection by ct followed by selective arterial embolization may be lifesaving. introduction renal angiomyolipoma (raml), is a rare, benign tumor arising from renal mesenchymal cells. frequently, it is asymptomatic and found incidentally. spontaneous rupture with consequent retroperitoneal hemorrhage is an uncommon but ca...
Background: The accuracy of reduction of ankle fractures using postoperative plain radiographies (x-ray) remainswidely controversial. Some authors have demonstrated that postoperative computed tomography (CT) scan can beuseful for these patients. In current study, the efficacy of x-rays after fixation of ankle fractures was investigated basedon the CT scan findings.Metho...
A patient presented with a painful third nerve palsy. This resolved spontaneously, but recurred several months later. At his second presentation carotid angiography gave normal results, but a high resolution CT scan showed a tumour in the right parasellar region. The serum prolactin was raised at over 22,000 millimicrons/, showing this to be a prolactinoma.
The outcome of patients with thoracic vascular prostheses is usually uneventful. We report two cases of collapse of thoracic vascular prostheses which occurred ten and forty years, respectively, after the implantation. The diagnoses were obtained preoperatively by CT-scan or NMR and angiography. Both patients were successfully treated with prosthetic replacement by an open approach.
