perivascular epithelioid cell tumor (pecoma) is a rare mesenchymal tumor composed of immunohistochemically and histologically distinctive perivascular epithelioid cells. here, we report on the computed tomography (ct) and magnetic resonance imaging (mri) findings of ovarian pecoma with pulmonary metastasis. the tumor was visible as a multilocular hemorrhagic mass that encased the ovarian vessel...

conclusion the designed split-bolus mdct technique can be proposed alternatively to triphasic mdct and in a single-pass to pvp in the initial staging and in the follow-up respectively in oncologic patients. patients and methods we retrospectively analyzed the follow-up split-bolus 64-detector row ct protocol in 36 oncologic patients to characterize focal liver lesions. the split-bolus mdct prot...

Continuous improvement in multislice computed tomography technology has further enabled advances in coronary artery bypass graft imaging. Multidetector platforms and retrospective electrocardiography gating have enabled sensitivities and specificities in the 95% to 99% range while avoiding the morbidity associated with invasive catheter angiography. Identification of bypass graft stenoses and b...

Background Vascular ring is less than 1% of congenital heart disease. Double aortic arch (DAA) is the most common form of it.  Its detecting is important because of the effects of pressure on the esophagus and trachea. Case Report In this study, three children suffering from double aortic arch with symptoms of dysphagia and recurrent aspiration, which in two cases had led to cardiac arrest, wer...

Life-threatening hemoptysis is a severe condition that requires rapid diagnosis and treatment. One of the treatments of choice is embolization. The initial assessment aims to locate the origin and cause of bleeding. The technological advance of the development of multidetector computed tomography (MDCT) has changed the management of patients with life-threatening hemoptysis. MDCT angiography ma...

Flat panel detectors have revolutionized tomographic imaging in the angio suite. Recent developments in hardware and software have improved soft tissue resolution and acquisition time even further, enabling soft-tissue and perfusion imaging within the angio suite. The so called “one-stop-shop” stroke imaging with flat panel detector computed tomography (FDCT) will significantly improve door to ...
