The aim of this study was to investigate radiation dose and image quality of coronary computed tomography (CT) angiography (CCTA) for patients with high heart rate variability (HRv) using 16-cm wide-detector CT scanner.
Although multidetector-row computed tomography (MDCT) before biliary drainage is useful for the assessment of the resectability of perihilar cholangiocarcinoma (PHC), the impact of biliary drainage on MDCT images before surgical resection for PHC has been poorly studied, and its possible consequences for R0 resection of PHC remain unclear. This study was performed to compare the surgical outcomes of patients with PHC who underwent MDCT before versus after biliary drainage.
The aim of this study was to evaluate the accuracy of cone-beam computed tomography (CBCT) for determining cortical thickness and the gray value, investigating its correlation with micro-computed tomography (CT) and histology analysis. Sixty-two bone samples from 4 anatomic regions of the jaw were analyzed. A radiographic surgical stent was used during CBCT and bone sample harvesting. The cortical thickness and gray value of the planned implant were evaluated by CBCT. Bone volumetric fractions, bone mineral...
To investigate the size and variations of the foramen transversarium (TF). In addition, to study the anatomical variations of the vertebral artery entering the transverse foramen of the cervical vertebrae.
Accuracy of Quantification of Iodine and Hounsfield Unit Values on Virtual Monochromatic Imaging Using Dual-Energy Computed Tomography: Comparison of Dual-Layer Computed Tomography With Fast Kilovolt-Switching Computed Tomography.
The aim of the study was to compare the accuracy of quantification of iodine and Hounsfield unit (HU) values on virtual monochromatic imaging (VMI) using dual-layer computed tomography (DLCT) and fast kilovolt-switching computed tomography (FKSCT).
High-accuracy diagnostic imaging is needed to diagnose and manage coronary artery disease as well as to allow risk stratification for future events. Advancements in multidetector computed tomography and image postprocessing allow for routine computed tomography coronary angiography to provide anatomic luminal assessment similar to invasive coronary angiography, and, similarly, computational fractional flow reserve derived from computed tomography facilitates determination of hemodynamically relevant stenosi...
Contrast enhanced cardiac computed tomography (CE-CT) provides useful substrate characterization in patients with ventricular tachycardia (VT).
In this heart failure patient, TEE images confirm the presence of the persistent left SVC with a dilated coronary sinus, severe mitral regurgitation, and aortic stenosis. Computed tomography reveals an isolated persistent left SVC and rules out anomalous pulmonary vein drainage or additional congenital disease.
The aim of this study was to determine the prevalence and computed tomography (CT) features of malignancy in incidental focal fundal gallbladder wall thickening.
The aim of this study was to better assess the prevalence and appearance of thymic tissue in adults stratified by age using multidetector computed tomography (MDCT) in order to prevent misinterpretation of normal thymic tissue as pathology.
Prior studies have compared radiographic and computed tomography (CT) imaging for evaluation of pre-arthritic hip pain. However, the inter-modality, inter-rater, and intra-rater consistencies of those parameters have not been investigated.
Cardiovascular computed tomography (CCT) is an important imaging modality in congenital and acquired paediatric heart disease. Technological advances have resulted in marked improvements in spatial and temporal resolution with a concomitant increase in speed of data acquisition and a decrease in radiation doses. This has elevated CCT from being sparingly used to an essential diagnostic tool in the daily multimodality imaging practice alongside echocardiography, cardiovascular magnetic resonance and invasive...
Increased arterial stiffness is reportedly associated with cardiac remodelling, including the left atrium and left ventricle, in middle-aged and older adults. However, little is known about this association in young adults.
The 13th Annual Scientific Meeting of the SCCT, held from July 13 to July 15 in Dallas, TX, was attended by 690 attendees from 39 countries, 55 sessions with 140 speakers, and 18 exhibitors with the abstracts of all scientific posters published in the Journal of the Cardiovascular Computed Tomography. This article summarizes the many themes and topics of presentation and discussion in this meeting, and the many technical advances that are likely to impact future clinical practice in cardiac computed tomogra...
Computed tomography (CT)-assessed sarcopenia indexes have been reported to predict postoperative morbidity and mortality; however conclusions drawn from different indexes and studies remain controversial.
Assessment of the Cerebral Hemodynamic Benefits of Carotid Artery Stenting for Patients with Preoperative Hemodynamic Impairment Using Cerebral Single Photon Emission Computed Tomography (SPECT) and Carbon Dioxide Inhalation.
BACKGROUND The aim of this study was to evaluate the effects of carotid artery angioplasty and carotid artery stenting (CAS) on cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) in patients with preoperative cerebrovascular hemodynamic impairment. MATERIAL AND METHODS Seventeen patients with unilateral severe internal carotid artery (ICA) stenosis and ipsilateral CVR impairment underwent CAS. CBF and CVR were measured by single photon emission computed tomography (SPECT) with inhalation of carb...
The purpose of this study was to evaluate intermediate and long-term changes in expiratory tracheal collapsibility by computed tomography (CT) in patients with tracheobronchomalacia following surgical treatment with tracheobronchoplasty and to correlate CT findings with clinical findings.
Assessing right ventricular function in patients with pulmonary artery hypertension based on noninvasive measurements: correlation between cardiac MRI, ultrasonic cardiogram, multidetector CT and right heart catheterization.
To compare the value of cardiac MRI (CMRI), ultrasonic cardiogram (UCG), multidetector CT (MDCT) in assessing right ventricular function (RV) in patients with PAH. A total of 31 consecutive patients with PAH (17 males and 14 females, 55±12 years) in Beijing Chao-Yang Hospital from August 2012 to February 2014 were prospectively enrolled. All patients underwent CMRI to get parameters including right ventricular end-systolic volume (ESV), end-diastolic dimension (EDV), stroke volume (SV), ejection fraction ...
Internal hernia is a rare cause of intestinal obstruction, and sigmoid mesocolon hernia is an extremely rare form of this condition. Among sigmoid mesocolon hernias, intramesosigmoid hernia is the least frequent subtype. We described a case of intramesosigmoid hernia through the orifice on the right leaf of the mesosigmoid with an incarcerated ileum of 6 cm in length without strangulation. This case was diagnosed by multidetector computed tomography with multiplanar reconstruction images and treated withou...
To quantify between-day reliability of upper-body diaphyseal measurements (radius, ulna, humerus) using peripheral Quantitative Computed Tomography (pQCT).
A 90-year-old female patient presented to the emergency department with abdominal pain. Computed tomography (CT) set the suspicion of a cardiac tumor in the right heart chambers. We describe the presentation, the differential diagnosis and the decision for management of the patient.
Aims Heart failure patients with LV dyssynchrony often do not respond to cardiac resynchronization therapy (CRT), indicating that the pathophysiology is insufficiently understood. Intracardiac hemodynamic forces computed from 4D flow MRI have been proposed as a new measure of cardiac function. We therefore aimed to investigate how hemodynamic forces are altered in LV dyssynchrony. Methods 31 patients with heart failure and LV dyssynchrony and 39 controls underwent cardiac magnetic resonance imaging with acq...
Usefulness of F Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in Infective Endocarditis in Daily Practice: Individualized Analysis of Each Potential Focus of Infection: A Prospective Cohort Study.
The clinical examination alone is widely considered unreliable when assessing fluid responsiveness in critically ill patients. Little evidence exists on the performance of the clinical examination to predict other hemodynamic derangements or more complex hemodynamic states.
No guidelines at present describe when fludeoxyglucose F 18-labeled positron emission tomography and computed tomography (FDG PET-CT) should be used in the initial posttreatment period for evaluation of oropharyngeal squamous cell carcinoma treatment outcome and recurrence.
