Background: CT scans with contrast media administration have been used to confirm the presence of pathology in blood vessel brain. High accuracy and fast scanning time produced by make this modality main choice assessing aneurysm Technological advances development CT-helical image acquisition techniques enabled neuroradiologists evaluate brain aneurysms a short time. Magnetic resonance (MR) ang...

BACKGROUND Use of computed tomography (CT) for diagnostic evaluation has increased dramatically over the past 2 decades. Even though CT is associated with substantially higher radiation exposure than conventional radiography, typical doses are not known. We sought to estimate the radiation dose associated with common CT studies in clinical practice and quantify the potential cancer risk associa...

introduction: in patients with coronary artery disease (cad) noninvasive evaluation for detection of ischemia is important to avoid invasive interventions like angiography. exercise stress test is conventionally the first study used in evaluation of cad. considering the noninvasive nature of the myocardial perfusion scan, we decided to compare its accuracy with stress test. methods: patients wi...

Pulmonary embolism is considered as a great masquerader due to its frequent nonspecific signs and symptoms. Typically pulmonary embolism is under-diagnosed or over-diagnosed. In this study a patient with pulmonary embolism is reported in which the patient exhibited two unusual manifestations namely; right upper quadrant abdominal pain and ST-T elevation in anterior precordial leads. Due to the ...

Neurological examination showed weakness limb without sensitive impairment. She had previous history bipolar affective diso...

Solitary fibrous tumours of the pleura (SFTPs) are rare and roughly 80% of them have a benign course. Malignant SFTPs are seldom reported, as are their computed tomography (CT) manifestations. We report the case of a 45-year old male patient who presented with coughing for over 2 months. A large lesion in his right hemithorax was found by chest X-ray. CT scan showed patchy areas and a sharp tim...

The newer approach to management of penetrating neck injuries (PNI) involves the No Zone approach: comprehensive physical examination combined with CT angiography for triage to effectively identify or exclude vascular and aerodigestive injury. This approach, however, has a low negative exploration rate; there is risk of missing occult injuries especially Zone I and III PNI. We report a case of ...
