conclusion the determination of the presence of mb2 in the maxillary first molars may be carried out using cbct scans. if the ∠mdp was 91 degrees or greater, there was considered to be a higher probability that mb2 canals would be found in the endodontic cavity. due to the positive correlation between the ∠mdp and the ∠mdmb2, the localization of mb2 canals may be easily performed in relation to...

objectives to evaluate morphologic variations at the aortic isthmus with particular attention to ductus diverticulum, a mimicker of traumatic pseudoaneurysm, and to describe differences using computed tomography (ct) images. patients and methods from december 2013 to december 2014, patients who underwent a chest ct examination after blunt trauma at our emergency department were included. aortic...

the possibility of abnormal avf was considered and it was confirmed on contrast-enhanced computed tomography (ct), inferring that this modality is not only fast and non-invasive, but also accurate in detecting vascular abnormalities. herein, we report a 42-year-old woman with congenital avf between the external carotid artery and external jugular vein, presenting with palpitation and dyspnea. t...

abstract background and aim: cone beam computed tomography (cbct) produces high-quality data in periodontal diagnosis and treatment planning. the aim of this study was to compare the accuracy of cbct with intraoral digital and conventional radiography in the measurement of periodontal bone defects.  methods and materials: in this diagnostic research, two hundred and eighteen artificial osseous ...

objectives: to compare the thickness of the lateral wall of the maxillary sinus in individuals with and without teeth to determine if extraction of the teeth can lead to a significant reduction in the thickness of the maxillary sinus lateral wall or not. patients and methods: in a retrospective study on fifty patients with an edentulous space, the thickness of the lateral wall of the maxillary ...

conclusion our results indicate that dsct coronary angiography provides high diagnostic accuracy for the evaluation of cad patients during daily routine practice of a referral cardiovascular setting. background there are numerous studies that address the diagnostic value of dual-source computed tomography (dsct) as an alternative to conventional coronary angiography (cca). however, the benefit ...

the reversed halo sign (rhs) may sometimes be seen in patients with cryptogenic organizing pneumonia (cop), but is rarely associated with other diseases. herein, we present a case of a 21-year-old woman with chronic eosinophilic pneumonia, with high resolution computed tomography (hrct) finding of rhs. this is an unusual and rare presentation of chronic eosinophilic pneumonia.

objectives: this study aimed to evaluate the location and characteristics of mental foramen, anterior loop and mandibular incisive canal using cone beam computed tomography (cbct). materials and methods: this retrospective cross-sectional study evaluated 200 mandibular cbct scans for the location of mental foramen, anterior loop prevalence and mandibular incisive canal visibility, its mean leng...

background: the implications of cardiac risk stratification before orthotopic liver transplantation (olt) are not well established. we studied the usefulness of myocardial perfusion imaging (mpi) in this scenario. methods: mpi data of 24 patients (9 females), candidates of olt, were collected. they underwent mpi as part of their preoperative risk assessment. mpis were interpreted by 2 nuclear p...
