Objective: The aim of this study was to detect and describe the existence and incidence of anatomical variations of the coeliac trunk by Using imaging technique. Materials and Methods: 80 patients visited the, radiology department of S.M.S.MEDICAL college jaipur . To cover the whole abdominal aorta in each patient, spiral CT angiography scan will be made and thin slices (0.6 mm) axial images wi...

Early reports established a role for MRI in the investigation of thoracic malignancy. Gamsu et a I (1) showed two main advantages over CT in the mediastinum: ease in distinguishing between lymph nodes and vascular structures and very high contrast between lesions and fatty tissue. The ability to scan in any desired plane is also an advantage. If direct comparison with chest X-rays is desired th...

Introduction: One of the main steps in the optimization process in diagnostic imaging is the quality control of radiology devices. The usual method of CT scan calibration is used of a phantom. The phantom created a certain weakening for the radiation through which it passes. One of the most suitable methods for quantitative analysis of the resolution and contrast in CT scan im...

A 25-year old male presented overnight with a single air rifle wound to the chest. A CT scan revealed a developing pericardial effusion with a pellet in the right ventricle (Figs 1 and 2). A right atrial entry wound was primarily repaired while on cardiopul-monary bypass in theatre. Figure 1: Chest computed tomography. (Left) Axial 1 mm section showing metal opacity within the right ventricle. ...

To improve the radiologic recognition of pituitary microadenomas that have subtle or no mass effect, the appearance of the normal pituitary gland on computed tomographic (CT) images was studied. Thirteen autopsy specimens of the pituitary gland and sella turcica were examined by coronal CT and histologically sectioned in similar coronal planes. The CT and histologic findings were correlated, th...

Introduction: Becuase of the most radiation dose receiving by human is related to medical radiation exposures, and also Computed Tomography (CT) is a special type of radiography that is one of the main method of radiation exposure today, and it's growing increasingly. Therefore, radio technologists working in CT scan imaging centers, are at risk of radiation. Due to the high am...

results the study consisted of 40 patients (all men, with mean age of 33.38 ± 7.4 years). ct evaluation with standard dose were positive in 22 patients (55%). only 1 (2.5%) ct scan assigned as unacceptable by each radiologist in low-dose group. noise average of low-dose protocol, was approximately 7 times greater than standard dose group, while dlp and ed are 9.7 times smaller. in comparison wi...

background: cone beam computed tomography (cbct) is an alternative to a computed tomography (ct) scan, which is appropriate for a wide range of craniomaxillofacial indications. the long‑term use of metallic materials in dentistry means that artifacts caused by metallic restorations in the oral cavity should be taken into account when utilizing cbct and ct scanners. the aim of this study was to ...

A 49 year old man with previous history of colectomy for colon cancer was referred to our department for further evaluation of suspicious hepatic lesions noticed during an abdominal CT scan. 99mTc-RBC scan revealed multiple hot spots in the region of the liver, correlating to the CT and liver-spleen scan. Further follow-ups of the patient revealed no remarkable change in the size or numbe...
