BACKGROUND AND PURPOSE Calcified cerebral emboli are a rarely reported but devastating cause of stroke and may be the first manifestation of vascular or cardiac disease. Our aim was to evaluate the diagnosis, prevalence, imaging appearance, presumed embolic source, treatment, and outcome of patients with calcified cerebral emboli. MATERIALS AND METHODS Our radiology information system was sea...

BACKGROUND It is generally well-known that smoking has a substantial impact on general health, and cardiovascular health in particular. The purpose of this study was to analyze the effects of different smoking status on the burden and characteristics of coronary artery plaques in Chinese men. METHODS Our study enrolled 1920 individuals with suspected coronary artery disease undergoing 256-det...

Calcified renal metastases from osteosarcoma are extremely rare. We present a case of a young female with osteosarcoma of the right ulna who developed late recurrence in the form of large metastatic calcified renal and pulmonary lesions. Review of the literature suggests that osteosarcoma metastases of the kidneys usually exhibit aggressive behaviour with poor prognosis. A brief review of the c...

OBJECTIVES This study sought to evaluate the long-term prognostic value of the number and sites of calcified coronary lesions and to compare the accuracy of number of calcified lesions with the extent of total calcium score. BACKGROUND There is a strong relationship between mortality and total coronary artery calcium (CAC) score. It is not known whether the number of calcified lesions or thei...

BACKGROUND Characteristics of individual calcified plaques, especially calcium concentration (CC), may provide incremental value to global calcium scores in the assessment of plaque burden and risk of coronary events and evaluation of therapeutic intervention. In this study, therefore, we assessed the characteristics of individual calcified plaques and their relationship to other parameters der...

thoracobiliary fistula is a rare complication of hydatid cyst of the liver especially in the calcified form. surgery is the only medical option. the treatment consists of radical surgical procedures in the majority of the patients. conservative surgical treatments are performed with high mortality rate. herein, we will describe two patients of calcified hydatid cysts of the liver whose conditio...

BACKGROUND Calcifications of atherosclerotic plaques represent a controversial issue as they either lead to the stabilization or rupture of the lesion. However, the cellular key players involved in the progression of the calcified plaques have not yet been described. The primary reason for this lacuna is that decalcification procedures impair protein and nucleic acids contained in the calcified...

Three patients with the central type of neurofibromatosis, who on CT showed multiple subependymal calcified deposits, are presented. The literature on intracranial non-tumourous calcifications in neurofibromatosis is briefly reviewed. On the basis of our findings and the literature, it is proposed that such intracranial calcified deposits may be part of the neurofibromatosis syndrome and are ca...

BACKGROUND High-speed rotational atherectomy uses a diamond-coated, elliptical burr to abrade occlusive atherosclerosis, especially noncompliant calcified plaque. METHODS AND RESULTS Intravascular ultrasound (IVUS) was used to analyze 28 patients after atherectomy. Arteries treated and imaged were left main (three), left anterior descending (12), left circumflex (five), right coronary (seven)...

BACKGROUND Material decomposition of dual-energy computed tomography (DECT) enables subtraction of calcified plaque. PURPOSE To evaluate the accuracy of lumen area measurement in calcified plaque by subtraction of DECT and to determine the effect of contrast material concentration, lumen diameter, density, and thickness of calcified plaque for the measurement. MATERIAL AND METHODS Vessel ph...
