"Dynamic imaging" (systolic compression) of myocardial bridge visualised by electronic beam computed tomography

Traumatic myocardial infarction visualised by computed tomography angiography.

Dynamic myocardial perfusion imaging by dual-source computed tomography.

We report a dual-source computed tomography study of dynamic and quantitative myocardial perfusion in a 44-year-old patient with previous documented coronary artery disease. Quantitatively, the tomography showed myocardial perfusion deficit in the territories with significant coronary stenosis, confirmed by computed tomography angiography and conventional angiography. Dual-source computed tomog...

Assessment of Accessory Mental Foramen by Cone-Beam Computed Tomography

Introduction: Any foramen in the buccal surface of mandibular body that transfers mental nerve and vessels except mental foramen, is called Accessory Mental Foramen (AMF). The objective of this study was the determination of the AMF using cone-beam computed tomography (CBCT). Materials and Methods:  this descriptive study was done on 180 CBCT projections which were selected by convenience samp...

Comparative Study between Electronic Portal Imaging Device (EPID) and Cone Beam Computed Tomography (CBCT) for Radiation Treatment Verifications

Introduction: Electronic Portal Imaging Device (EPID) and Cone Beam Computed Tomography (CBCT) are the preferred tools of Image Guided Radiotherapy (IGRT) and Dose Guided Radiotherapy (DGRT) which have been used for Radiotherapy treatment verifications. As a result, the number of publications dealing with these two tools for radiation treatment verification has increased consi...

Dosimetry of Critical Organs in Maxillofacial Imaging with Cone-beam Computed Tomography

Background: While the benefits of cone-beam computed tomography (CBCT) are well known in maxillofacial imaging, the use of this modality is not risk-free.Objective: The aim of this study was to evaluate the exposure doses received by patients during maxillofacial imaging with CBCT.Methods: Entrance surface dose (ESD) was measured by using thermoluminescent dosimeters (TLDs) attached to the eyes...
