PURPOSE To assess the role of fine-needle aspiration biopsy (FNA) in the evaluation and management of breast masses in adolescents. METHODS All FNAs performed on organ masses over a 15-year period on patients age 21 years and younger were evaluated. Cases were collected from four large university-affiliated teaching hospitals and clinics. Pathology(More)
The CT appearance of focal and diffuse fatty infiltration of the liver has been described in recent radiologic literature. Previous reports of focal steatosis have emphasized the differential diagnosis of the solitary lesion. We report a case of multifocal hepatic involvement and describe a new radiologic sign that is useful in differentiating this process(More)
A 77 year old female with asymptomatic severe aortic stenosis (AS) and normal LV systolic function was referred for exercise stress echocardiography (ESE) in order to assess whether she is truly asymptomatic and to risk-stratify her aortic valve disease. While she only developed minimal breathlessness after 4.2 min of Bruce protocol and no other high risk(More)
This work is on formal modeling, analysis and detection of job interference in large distributed multi-agent systems. Such an analysis usually requires an examination of all the global system states—often impossible due to the well-known state space explosion. We obtain a sufficient condition so that job interference can be detected by observations of(More)
