BACKGROUND Computerized tomographic scans are routinely obtained to evaluate a number of musculoskeletal conditions. However, since computerized tomographic scans expose patients to the greatest amounts of radiation of all imaging modalities, the physician must be cognizant of the effective doses of radiation that are administered. This investigation was performed to quantify the effective dose...

BACKGROUND The correlation between normal cardiac chamber linear dimensions measured during retrospective coronary computed tomographic angiography as compared to transthoracic echocardiography using the American Society of Echocardiography guidelines is not well established. METHODS We performed a review from January 2005 to July 2011 to identify subjects with retrospective electrocardiogram...

BACKGROUND Hepatic portal venous gas (HPVG) in adults is a rare entity. The underlying pathologic condition is usually an intestinal ischemia, but it has been reported in association with a variety of conditions. HYPOTHESIS Miscomprehension of the underlying pathologic conditions has led to some confusion in the literature concerning its etiology, diagnostic methods, and clinical consequences...

hydatid disease is a rare parasitic disease, which mainly involves liver then lung tissues. cardiac involvement is very rare, especially when there is not hepatic involvement. we describe a 47-year-old woman with a history of a lung hydatid cyst who was referred to rajaei heart center, tehran, iran in 2012. her chest computed tomographic scan showed a cardiac mass. echocardiographic examination...

BACKGROUND Computed tomographic angiography is increasingly used during surgical planning for abdominally based microvascular breast reconstruction. Cost-analysis studies have demonstrated a benefit to the use of computed tomographic angiography, although the secondary costs of incidental findings have not been previously reported. This study investigates the cost of computed tomographic angiog...

BACKGROUND Early diagnosis of pulmonary hypertension (PH) can potentially improve survival and quality of life. Detecting PH using echocardiography is often insensitive in subjects with lung fibrosis or hyperinflation. Right heart catheterization (RHC) for the diagnosis of PH adds risk and expense due to its invasive nature. Pre-defined measurements utilizing computed tomography (CT) of the che...

A 76 year old man with shaking movements of the fingers, weakness of the arm and lacunar infarctions on computed tomographic scan is described. The shaking limb should be included in the group of lacunar syndromes.

The case is presented of an 82 year old woman with breathlessness, stridor, and upper mediastinal widening on chest radiography. Computed tomographic scanning showed tracheal compression by aneurysms of the brachiocephalic and left common carotid arteries.
