In this series a pictorial quiz pertaining to identification of normal anatomical structures and landmarks at a given level on the computed tomography (CT) is presented. An image depicting normal anatomy is followed by a series of images showing different pathologies. Readers are expected to identify and appreciate variation and changes in the normal anatomy in presence of a given pathology. Th...

This letter underpins the use of three-dimensional computed tomography (3D-CT) reconstruction as an aid to teach veterinary anatomy. Cases were presented to students in order to observe normal and clinically abnormal patients. The images provided excellent details of relevant structures and could serve as a tool for teaching anatomy. Many sources describe different options to enhance anatomical...

Objectives- to provide a reference anatomy of the bronchial tree of the Jebeer Gazelle by using computed tomographic modality. Design- Experimental study. Animals- Three female Jebeer Gazelle Procedures- Spiral CT images were taken from the thoracic region perpendicular to long axis of the body. CT windows were adjusted as necessary to have optimized images of pulmonary organ. The images ...

OBJECTIVE In this part one of a two-part article, we aim to illustrate our understanding of and approach to comprehensive cardiac CT reporting, cardiac CT technique, and coronary calcium scoring CT, as well as normal and anomalous coronary artery anatomy. CONCLUSION Structured cardiac CT reporting is important to effectively communicate with referring clinicians. Knowledge of cardiac CT techn...

Three-dimensional (3D) printing is increasingly being used for congenital heart disease to allow an in-depth understanding of complex cardiac anatomy; however, access 3D hindered by lack access. This study investigated the feasibility rapid prototyping (RP)using a readily available on-site printer. Patients with anatomy were prospectively identified. All patients underwent ECG-gated computed to...

Introduction: Use of SPECT/CT data is the most accurate method for patient-specific internal dosimetry when isotopes emit single gamma rays. The manual or semi-automatic segmentation of organs is a major obstacle that slows down and limits the patient-specific dosimetry. Using digital phantoms that mimic patient’s anatomy can bypass the segmentation step and facilitate the dosi...

The purpose of this study was to develop an approach to generate artificial computed tomography (CT) images with known deformation by learning the anatomy changes in a patient population for voxel-level validation of deformable image registration. Using a dataset of CT images representing anatomy changes during the course of radiation therapy, we selected a reference image and registered the re...

anatomy: middle cranial fossa mainly floored by sphenoidal bone and located post. to innominate bone or lesser wing and ant. to temporal bone. main foramens are located in deep part, bilateral to sellae are orbital fissures, optic canals, foramen rotundom, ovale and spinosum, foramen lacerum also meckle cave or trigeminal impression and carotid canal. this fossa is like a butterfly in shape. le...
