OBJECTIVE To assess the sensitivity of the routine computed tomographic (CT) scan of the temporal bone coupled to a virtual endoscopy, with density threshold variation, in detecting small fistulas in human temporal bone specimens. DESIGN Single-blind, before-after trial. SETTING This study was carried out in a research laboratory in collaboration with a radiology department. PATIENTS Five...
Abstract Background: The purpose of this study was to evaluate the significance of the Q angle with respect to the patella position. We assess the correlation between the Q angles (calculated by clinical exam) in different positions and CT indices (with more impression on TTTG). Method: Atotal number of 68 knee joints of 50 cases entered the study. Clinical examination was used to m...
The use of computed tomography (CT) as a diagnostic tool has been considerably increased. Therefore, the controlled and protection-based use of the CT scan is necessary to reduce the detrimental effects of radiation. This study was carried out to determine patient dose level in routine CT protocols and measure CTDIW and DLP in routine CT protocols among adult patients in Kashan Shahid Beheshti ...
In the 1980s CT imaging of coronary arteries began after the introduction of electron beam CT (EBCT), with the main application being quantification of calcifications in the coronary arteries for risk stratification. In the late 1990s helical multidetector row CT (MDCT), starting with the four-detector row, was used for noninvasive evaluation of suspected coronary artery disease. Initially MDCT...
conclusion spiral-ct scan is superior to conventional ct in the diagnosis of lesions in com before operation. it can be used for detailed evaluation of ossicular chain in such patients. objectives this study was performed to compare the findings of three-dimensional reconstructed spiral and conventional ct scan of ossicular chain study in patients with com. patients and methods fifty patients e...
Background and Objectives: Investigating the changes in CT scans of patients is one of the most important methods to determine the prognosis of patients with head trauma, which has been considered by researchers. The aim of this study was to determine the findings of delayed CT scan in blunt head trauma patients referred to Shahid Bahonar Hospital of Kerman in 2020. Methods: This was a descript...
There are considerable rates of pediatrics trauma referring emergency department following a traumatic event. The worried parents are requesting for the most sensitive diagnostic test, so emergency physicians ask them to underwent brain computed tomography (CT) scan. Lower threshold of decision making regarding use of brain CT scan results in huge number of normal imaging. On the other hand, ra...
